    • We recommend that you clean your microwave before proceeding, as any nasty gunk on the bottom may end up stuck to the iOpener.

    • Place the iOpener in the center of the microwave.

    • For carousel microwaves: Make sure the plate spins freely. If your iOpener gets stuck, it may overheat and burn.

  2. iPad 4 CDMA Logic Board Replacement: adım 2, 1 resimden 1.
    • Heat the iOpener for thirty seconds.

    • Throughout the repair procedure, as the iOpener cools, reheat it in the microwave for an additional thirty seconds at a time.

    • Be careful not to overheat the iOpener during the repair. Overheating may cause the iOpener to burst. Do not attempt to heat over 100˚C (212˚F).

    • Never touch the iOpener if it appears swollen.

    • If the iOpener is still too hot in the middle to touch, continue using it while waiting for it to cool down some more before reheating. A properly heated iOpener should stay warm for up to 10 minutes.

  3. iPad 4 CDMA Logic Board Replacement: adım 3, 1 resimden 1.
    • Remove the iOpener from the microwave, holding it by one of the two flat ends to avoid the hot center.

    • The iOpener will be very hot, so be careful when handling it. Use an oven mitt if necessary.

    • If you don't have a microwave, follow this step to heat your iOpener in boiling water.

    • Fill a pot or pan with enough water to fully submerge an iOpener.

    • Heat the water to a boil. Turn off the heat.

    • Place an iOpener into the hot water for 2-3 minutes. Make sure the iOpener is fully submerged in the water.

    • Use tongs to extract the heated iOpener from the hot water.

    • Thoroughly dry the iOpener with a towel.

    • The iOpener will be very hot, so be careful to hold it only by the end tabs.

    • Your iOpener is ready for use! If you need to reheat the iOpener, heat the water to a boil, turn off the heat, and place the iOpener in the water for 2-3 minutes.

    • If your display glass is cracked, keep further breakage contained and prevent bodily harm during your repair by taping the glass.

    • Lay overlapping strips of clear packing tape over the iPad's display until the whole face is covered.

    • This will keep glass shards contained and provide structural integrity when prying and lifting the display.

    • Do your best to follow the rest of the guide as described. However, once the glass is broken, it will likely continue to crack as you work, and you may need to use a metal prying tool to scoop the glass out.

    • Wear safety glasses to protect your eyes, and be careful not to damage the LCD screen.

    Yes...wear safety glasses for sure when doing this!

    Josh West - Yanıt

    If you have ANY cracks FOR SURE do the tape. I would also make sure to wear safety glasses as it can fly all over even with the tape. And do it somewhere that you don't mind tiny glass shards going everywhere. I had one 3 inch crack in the glass in the lower right corner and it started spidering. The plastic pics don't work once well once they hit a broken point in the glass so you better have a lot of heat to loosen the adhesive, or you end up using an exacto knife to get around the cracked spots.

    jesseokerlund - Yanıt

    On a few occasions I had an unexpected pop as the glass shattered and little shards struck me in the face. I had taped the surface but pieces at the edge still managed to break free. My advice: definitely wear the safety glasses, and definitely tape the entire glass surface.

    robertmhussey - Yanıt

    Echo jesseokerlund's comments that you will have glass flying. I made the mistake of doing the repair at my kitchen table and had a lot of cleanup to do. The job would be much easier if there was no broken glass, and the hardest part is where the glass is broken right next to the bezel. I used the metal spudger to work those pieces free, but it takes some time.

    robertmhussey - Yanıt

    + 1 on the safety glass, I almost got hurt while doing this.

    alexisfogel - Yanıt

    I followed all the safety precautions mentioned: tape, safety glasses… The best advice I saw on this is to put the iPad in the sun for a few minutes. I placed mine on the windshield of my car in direct sunlight for about 5 minutes. I also used the iOpener to keep heat on the edges I wasn’t working on. I was able to easily remove the glass without any shards flying in about 30-40 minutes total. Great advice and safest way I’ve seen to remove broken glass.

    • Again, as you may find yourself working with broken glass during this procedure, we strongly recommend wearing safety glasses for protection from flying shards.

    • Lay the iOpener flat on the right edge of the iPad, smoothing it out so that there is good contact between the surface of the iPad and the iOpener.

    • Let the bag sit on the iPad for approximately 90 seconds before attempting to open the front panel.

    It is ver likely that the glass you are trying to replace is broken, and this is tempered glass therefore it will chatter in many small pieces while you are working on it. Take this safety advice very seriously and protect your eyes!!! The glass pieces fly everywhere. AGAIN: PROTECT YOUR EYES!!!! BE SAFE!!!

    McGiord - Yanıt

    This last statement cannot be underemphasized! I got two shards of very fine glass into my right eye, luckily got them out right away, before reaching for the safety goggles! Later on, I removed them again because working w/ the small parts was easier. Protect your eyes, people!

    Lou Bomski -

    Just use some scotch wide transparent tape and cover the broken screen BEFORE you start to taking it apart. It will hold all the shards together and nothing will fly around.

    Vatevaaa -

    I covered the screen in clear packing tape to control glass particles.

    I placed the ipad outside in direct afternoon sunlight for an hour and all of the adhesive was softened quite well.....the screen was off in just a few minutes !

    This is a very good idea John, I wish I'd seen this comment before I spent hours picking tiny bits of glass off the glue!

    Thumbs up for this tip. I left it out in the sun for 15 min only and it worked a treat. I used a razor blade. The plastic tools are next to useless.

    I had some issues after replacing this cable.

    Once I had it in and back together only the down volume was working, and shortly after the gyro gave out.

    I ended up going to where the new cable connects to the board, removing it, then replacing it as gently as possible. Not too firm.

    I also removed a foam spacer in that area because it was pushed out over the gyro board.

    Now I'm back to full functionality!

    Badly broken screen, taped and warmed about 15 minutes on heating pad set on high. Perfect, gentle, overall warming! Mark the front with Sharpie, ie WiFi, cable, etc. Used thin metal iSes... type tool and guitar pics. BUY NEW Plastic bezel!!! So super cheap. Rewarm on heating pad as necessary. Compressed air helpful to blow away tiny glass bits. Wear glasses! Take breaks! This is easy if you warm carefully and are patient!

    Max - Yanıt

    I am in the process of replacing a shattered screen on an iPad 3 wifi, and I literally was removing glass piece by piece! I do recommend having a roll of wide clear sealing tape at hand. Then, when you see loose glass shards, pull off about 4 to 5 inches, and stick the tape to pick up the loose glass, and once in a while, fold the tape onto itself (sticky to sticky side), and set it aside. This helps keep it from getting everywhere. Also, spread news paper under your work. Some people don't really think of these things, but the fact is, hardened glass will find its way into your skin very easily. Extremely sharp!

    Have not attempted this repair on my wife's iPad 2, but is there a reason that you put the iOpener on top of the device rather than putting the device on top of the iOpener? After all, heat rises.

    • There is a small gap in the iPad's adhesive ring in the upper right corner of the iPad, approximately 2.0 inches (~5 cm) from the top of the iPad. You are going to exploit this weakness.

    • Align the tool with the mute button. Insert the tip of a plastic opening tool into the gap between the front glass and the plastic bezel. Just insert the very tip of the opening tool, just enough to widen the crack.

    • It may require some force to get the wedged tip of the opening tool between the glass and plastic. Work patiently and carefully, wiggling the plastic opening tool back and forth as necessary.

    there is the power flex cable near the top right side of the screen. It could be damaged is not careful.

    cli168 - Yanıt

    Yes, I severed this one on my first attempt. Might note that you want to start prying open below the sound controls. Additionally I found that a razor was helpful in getting the first pic into the device. Obviously you want to be careful as a razor could cause some serious damage, but I just used the tip of the metal to get some space to fit a pick.

    Nick Dresang - Yanıt

    Maybe I was doing it wrong, but the plastic opening tool I was using kept bending before it was prying anything apart. Therefore I suggest using either a metal spudger or a razor blade to make the very first opening but being VERY careful. My assistant/wife later scratched the LCD going overboard with the metal tools.

    Logan Kennedy - Yanıt

    There is a way of making the Wifi/Bluetooth Antenna replacement much easier. If you have a steady hand and a soldering iron simply desolder the connecting cable from the bottom of the antenna and solder it back onto the new antenna. This means there is no need to dismantle the iPad and the repair is much faster. Hope this helps :-)

    Richard - Yanıt

    The process was pretty straightforward, you do need to be careful in a few spots (like the wifi antenna in the lower right) but overall I found it to be of medium level of difficulty.

    It took me 2.5hrs to slowly dismantle and replace the broken screen.

    Here are some tips I learned while doing it:

    - instead of plastic spudger, better to use kit knife or razor blade. I found plastic to bend and malform quite easily.

    - watch out for lower right corner where wifi antenna sits, it's easy to damage it

    - if you have a cracked screen, use protective goggles - i used tape to secure broken glass pieces together, but that didn't quite work and lots of glass was flying as I was prying the screen off the ipad

    - opening tool you put in the microwave sold here is not worth it - didn't do that great for me. I mostly used a hair drier and was very successful melting adhesive

    - tools I'd only need again to do it again - guitar picks, kit knife, phillips screwdriver, hair drier :D

    Overall, I found it to be quite interesting project!

    michalmotykiewicz - Yanıt

    Seconding the problem about plastic components. They just aren't strong / precise enough to fight this glass. Save them for the really nasty bits like the wifi cable, and use an X-Acto or equivalent everywhere else.

    Golden Neckbeard -

    Wish I would have seen your comment before I went through it. Switched to a razor blade and that helped for sure. Thought about a hair dryer as well but stuck with the micro heating tool. Probably should have done the dryer. :-/

    Josh West -

    Had much more success using the metal spudger versus the plastic opening tool that came with the front panel kit.

    Paul Boyer - Yanıt

    I had success using Paddle Pop sticks instead of guitar picks. (not sure what they are called in the US). The guitar picks tended to deform and melt with the heat of my hot gun. The glue used to attach the screen is just amazingly strong! It takes a lot of patience to remove all the fragments. I have done about 6 screens now and it is a turdful job!

    Jack - Yanıt

    I think we call those popsicle sticks. They seem kind of thick for this, at least a lot thicker than a guitar pick.

    John -

    It is not glue, they use a very strong double sided 3M tape

    Pay attention to the Power Button cable located in the upper right corner !!!

    Nathan - Yanıt

    Successful battery change but I did sever the cord/ribbon to the power/sleep button. As my iPad had been opened before at a repair shop, I think they put adhesive over the cord as the small section was stuck underneath the LCD, barely visible. So be careful not to put adhesive above that exposed ribbon/cord to the power/sleep button or the next time you open it up, it's severed.

    Breadman - Yanıt

    On the iPad 2 I repaired, the opening started at 1 inch and ended at 3mm.

    Justin H - Yanıt

    Like others i found the plastic tool pretty useless. Exacto, razor blade, or small metal pick/pry tool works much better to get that first guitar pick inserted. Be careful not to damage the bezel too much. Unless to plan to replace it.

    B Kirkham - Yanıt

    If you have an iPAD that has been repaired before note that the adhesive strip might not have an opening by the volume control as shown. I replaced the glass and the new glass had a 2" gap to the left of the Home button only.

    winwoodc - Yanıt

    The glass is much thinner than you'd think and I broke mine trying to lever it off before the adhesive has softened enough. Be VERY gentle!

    winwoodc - Yanıt

    My plastic opening tool broke in no time flat. Perhaps I was pressing down too hard and not wiggling it enough. But for me I found that the metal spudger was the best tool for the job. I was able to wiggle it while slowly prying up the glass and once it was under the surface of the glass I was able to work it along the edge quite easily. I saw that some people used a razor blade but I would be afraid the blade would break. The metal spudger was just thin enough to do the job well.

    robertmhussey - Yanıt

    sean blanche - Yanıt

    I have found that using these plastic picks, spudgers and edge tools are ineffective as tools for inserting or creating a gap and glue separation action.

    They are just too soft and too thick for this, causing cracks and not able to reach underneath without causing stresses.

    After heating the adhesive with a heat gun (and using cardboard to shield the lcd screen) I have been using a metal round headed scalpel to insert between the glass and bezel, and to very carefully use as an adhesive separation tool at a very oblique angle so as to miss any sensitive cables or components.

    Also, instead of this iTool heating pad and a microwave, they should create an electrically heated shaped pad, this would avoid the constant cooling and reheating and maintain the right temperature.

    G Trieste - Yanıt

    Addendum, I have a temperature controlled heat gun, and set it to 180F for this.

    G Trieste - Yanıt

    The iOpener works fine, I'm not sure what y'all are talking about. To be fair, you have to press the iOpener into the iPad in order for it to work, which isn't explained well in this tutorial. Wear heat-resistant gloves when you do this, the center portion of the iOpener gets VERY hot. I use a pair of gloves from ACE Hardware. While it takes a bit more effort with the picks, I was able to heat up one side of the iPad, then seperate the adhesive with the picks the rest of the way through.

    I do not recommend using the little blue tool they show above, the part you're supposed to wedge in is way too thick. I use the Jimmy and some opening picks.

    Third image is slightly misleading, you want to go about a centimeter below the volume button.

    • Make sure you place the tool in the proper spot—between the plastic display bezel and the front panel glass.

    This visual is helpful. It would be great also to have a diagram of the top of the ipad, marked with "top," "bottom," "left," "right," and then an arrow pointing to each of the problematic areas, such as wifi cable, digitizer cable, etc. It would be easier to see the whole schematic while working rather than scrolling through the instructions and trying to visualize each piece separately. Good to see where to be careful...

    • Keeping the tip of the plastic opening tool wedged between the front glass and plastic bezel, slide a plastic opening pick in the gap, right next to the plastic opening tool.

    My screen was too broken for this "heat, cut with picks, and leave in place" method to work anywhere but the top, where it was essentially undamaged.

    I wound up using a spudger through all the cracked sections to pry upwards just *inside* the perimeter of the adhesive, intentionally breaking the digitizer and the glass further, until I could remove the entire front panel except for the adhered portions - about half the perimeter in my case.

    I then used tools to pry up the glass from the *opposite* direction, that is the broken interior edge I had earlier created, thus not having to fight the bezel and also having a clear line of sight to any interior components I might be damaging.

    Of course, doing it this way made it much easier to drop tiny shards of glass all over the interior, but I found a little diligent cleaning much easier than trying to keep the glass intact while breaking the glue, as in this guide.

    Golden Neckbeard - Yanıt

    I found that using a scraper blade was the easiest way to get under the glass, both for broken and unbroken areas.

    • Remove the plastic opening tool from the iPad, and push the opening pick further underneath the front glass to a depth of ~0.5 inches.

    It should be noted that the glass can be much more difficult to remove when it is cracked and shattered (as is usually the reason for replacement) . Depending on the location and severity of the cracks, the order and technique of removal requires modification.

    I have found that putting a layer of clear packing tape over the entire screen is helpful, wether it's cracked or not. It will prevent the spraying of glass shards, should the glass break while separating the adhesive; with a broken screen, it should eliminate the risk of cutting yourself during removal, as well as hold all the pieces together. Unfortunately, it also makes the iOpener slightly less effective, so peel it back when applying it. Suction cups can also be helpful during final removal of the glass.

    Having a hot air gun/pencil can be helpful in removing smaller pieces if broken glass that remain once the bulk of it is removed.

    Just trashed an I pad... Not an electronics person. Did an iphone 5 battery with no problems was following instructions and once I hit the next step I realized I had already screwed up the screen... Moving forward tring to unhook LCD pictures are not very clear on which direction to push or pull so broke that... Now writing a review on it... Take it to a pro if you aren't certain!

    rondiedonelson - Yanıt

    I found that the adhesive could be separated when the pick or spudger was in at a depth of between 1/4" (6.4 mm) and 3/8" (9.5 mm). You can always go back and work it in deeper if you are having trouble separating.

    robertmhussey - Yanıt

    Yoh but this is not so simple of your screen is shattered to the edges. Basically I had to lift, shatter more, and then pick off the splintered glass with tweezers bit by bit. Patience is a virtue here. I gave up on saving the adhesive and used it to help remove the splinters. I basically removed the edges of the iPad like that and then lift glass off. WEAR SAFETY GLASSES. I would be blind now if I didn’t. wifi antenna -Go slow make sure it’s hot +check what you are doing in the crack. Remove all splinters fromiPad when it’s open. Clean LCD with a microfibre cloth and inside of your new digitizer. When I first reassembled, the home button didn’t work. I reopened and made sure the two gold connectors align with the two spikes on the body. I placed the home button board face down onto the connector spikes with adhesive on the other side, then lowered the digitiser onto it so the board would stick to the digitiser. Notes: forget plastic spudger they’re only place holders, I used a blade knife and metal Spudgers

    • While you work on releasing the adhesive on the right side of the iPad, reheat the iOpener, and replace it on the bottom edge of the iPad.

    I have found that its better to put more than one pick down the side of the screen to keep it open and prevent it from sticking back down.

    • While the bottom edge is being heated by the iOpener, begin releasing the adhesive from the right edge of the iPad.

    • Slide the opening pick down along the edge of the iPad, releasing the adhesive as you go.

    • The adhesive is very strong, and some serious force may be required. Work carefully.

    • If you can see the tip of the opening pick underneath the front glass, pull the pick out just a little bit. While using the opening pick this deep won't damage anything, it may get adhesive residue all over the LCD.

    • It may be necessary to move the heated iOpener back onto the right edge of the iPad as you release the adhesive. This depends on how long the iPad has been able to cool while you were working on it.

    • If the opening pick gets stuck in the adhesive, "roll" the pick along the side of the iPad, continuing to release the adhesive.

    The volume power button cable is really close to the edge and is frequently loose and non adherent to the frame. If your pick is deep into the iPad, you are almost sure to cut the cable. Be very cautious around the top right corner of the iPad.

    silvain1038 - Yanıt

    I absolutely severed this cable when loosening the adhesive around the volume button area. There is really no way of knowing if this cable somewhat elevated from the frame and therefore susceptible to being cut, and it happens to be right where one starts to remove the face with the guitar picks. The cable is directly in from the down volume button, so be extra careful not to put the guitar pick in too far in this area. I recommend buying a power/volume button cable just in case. Replacing this cable is also not easy, but doable. Just try to avoid doing it.

    nickmalmquist - Yanıt

    Why not work in reverse to the top edge, and back around to the area where that cable may be unsecured? Haven't don't an iPad (yet, staring one in the face right now) but that would be my alternative so the screen is mostly loose and you could possibly see the cable looking from the now open left side of the glass?

    • Before removing the first opening pick from the bottom corner of the iPad, insert a second pick under the right edge of the front glass to keep the adhesive from re-adhering.

    • Re-heat the iOpener, and move it to the top edge of the iPad.

  17. iPad 4 CDMA Logic Board Replacement: adım 17, 1 resimden 1.
    • The next few steps require extreme caution.

    • The Wi-Fi antenna is attached to the bottom right edge of the rear case of the iPad via screws and a cable. Because of the orientation of the Wi-Fi antenna, it is imperative to proceed with caution otherwise irreversible damage to the Wi-Fi antenna may result.

    • You will have to release the adhesive securing the antenna to the front panel without damaging the delicate parts attaching the antenna to the bottom of the iPad. Follow the next steps carefully.

    I cut through my wifi cable partially, but it still works (surprisingly). I'd recommend staying well clear of this with the pick. When you go to lift the screen (future step, NOT NOW), use a really good light, start to lift the glass slightly at the corner and you will be able to see the cable. Then you can heat it more and watch the cable as you pull through the adhesive there making sure your not catching the cable.

    B Kirkham - Yanıt

    If you heat the sides and top, releasing the adhesive, you can peel the broken glass front panel up from the body and with a little force the bottom comes loose. This avoids working around and damaging the Wi-Fi Antennae.

    Michael Vovaris - Yanıt

    I know it is hard to tell from the photo, but the Wi-Fi antenna is kind of like a flap that opens on the right and is attached on the left. So if you use a pick to slide from right to left, the pick might slide under the flap and then sever how it is attached. When I had my pick just to the right of where the Wi-Fi antenna is, I was able to twist my pick a little (like you are tightening a screw) and pry the screen up where the antenna is located. Then I just moved my pick to the left of the antenna and could continue loosening the screen.

    Laurie Higgins - Yanıt

    Irreversible damage to the Wi-Fi antenna is nearly unavoidable, but this is not the end of the world since you can pick up a perfectly fine replacement on-line for a few bucks. Many digitizer screen replacement kits include a new WiFi antenna and new bezel since removing the screen without damage to these is also nearly impossible. If your iPad is old enough to need a new battery, and you plan on keeping it thru at least another battery's expected life span, then I would plan on replacing the digitizer screen, bezel, and WiFi antenna as part of the battery replacement. The battery is going to be the most expensive of the set, say around $15 (US), and adding the other three will only add about another $15 (check the prices in ebay, amazon, etc.). Removing the screen often results in damage to the on/off and volume control cable since it too runs along the upper right hand edge of the base right under the screen. If you cut thru this then add another $1 to replace it too.

    Jerry - Yanıt

    Based on my experience just (nearly) completing this job on an iPad 2, CDMA, is that the trickiest step is reconnecting the three CDMA antenna cables on the underside of the CDMA chip that is part of the logic board assembly. These are nearly microscopic button connectors (maybe 0.5 mm in diameter). I needed 8X magnification glasses, very bright light, tweezers, and incredible luck to get these reattached. They pop off no problem, but getting them positioned to apply pop-on force takes a LOT of patients! Maybe someone knows a trick to doing this? There’s a similar connector on the WiFi cable but the chip it attaches to can be removed from the logic board so you’re able to manage positioning them interdependently. The CDMA chip is attached (soldered?) to the logic board and the three button connectors are on the underside, and pretty close to one another, so getting all THREE attached and then the logic board in place is a miracle.

    • Slide the opening pick around the bottom right corner of the iPad, releasing the adhesive there.

    • Do not slide the pick further than the bottom right corner. You may damage the Wi-Fi antenna by doing so.

    Be sure to have a replacement Bluetooth Wi-Fi antenna because it is very likely to get the cable broken at this step.

    McGiord - Yanıt

    Be extremely careful and patient at this step. Proceed slowly with only the tip ( 1/16th in. - 2mm max.) of the pick. There are two tinny screws that attach the bottom of the antenna to the iPad frame. This antenna part is easly severed if the pick goes too far.

    • This step requires you to move the opening pick along the bottom right edge of the front panel. The Wi-Fi antenna is very close to the corner and is easily severed if the adhesive is released improperly.

    • Do not completely remove the pick from under the front glass, but pull it out just a little bit so that ~1/8" (3 mm) of the tip is still under the front glass.

    • Slide the tip of the opening pick along the bottom edge of the iPad, releasing the adhesive over the Wi-Fi antenna.

    I nearly broke my wifi antenna because I didn't read this whole step clearly and didn't go backwards and release the antenna from the front panel. Admittedly, this is my own fault but I've edited the step to make this point more clear.

    Logan Kennedy - Yanıt

    My screen was way too shattered for me to be able to use the screen instructions as suggested, so I followed the general principal but ignored the order around, because that simply wouldn't have worked...and destroyed the antenna.

    Maybe step one should be "BE CAREFUL IN THIS CORNER OR YOU WILL BREAK THE ANTENNA!" A diagram highlighting where all the cables (antenna, digitiser, volume, toggle switch) lie with the screen still attached would be helpful too.

    I Broke my antenna like many others. It is glued to the glass and has 1mm thick foam backing that is also glued to the inner case. Then there is a tiny grounding connector screwed at the lower edge of the case. Once you can get things loosened up around this antenna, you will need to detach this antenna from the glass. Work at it with your picks or spudger until you get it free, if you do not get it to release from the glass you will break the grounding ribbon. I bought a cheap aftermarket antenna on amazon for $3. turns out it has a bad cable coming from it. I was able to unsolder the cable from the one I broke and solder it to the new antenna.

    It wasn't obvious to me at first that I'd broken the antenna. A picture of the antenna that works compared with one that is broken would be useful. Fortunately I'd ordered the replacement part just in case, as suggested.

    I think using extra heat on this spot may make it easier to unstick without breaking the antenna?

    A diagram of what the antenna looks like, from the side, would make it clearer what to do with the pick. You are trying to detach the antenna from the glass, without ripping it off where it's screwed into the bottom of the ipad. Since you can't see what you are doing, and the antenna is quite fragile, that's tricky.

    I think once you've broken one you would know better how to do it. When you slide the pick to the right you need to be sure the pick is moving above the antenna and not snagging on it in any way, and you need to be sure the antenna is completely detached from the glass, so you don't tear it when you lift the glass up.

    Another lesson learned while removing the WiFi antenna. The photo shows the iPad laying face up on the table, but to see what you’re doing when detaching the antenna you ‘re better off with the iPad edge up so you can see how the antenna is attached. The antenna is very, very easily broken. To be honest, it’s a lot easier to replace a broken antenna than to try to pry it loose.

    • Once you have moved past the Wi-FI antenna (approximately 3" (75 mm) from the right edge, or right next to the home button) re-insert the opening pick to its full depth.

    • Slide the pick to the right, releasing the adhesive securing the Wi-Fi antenna to the front glass.

    • The antenna is attached to the bottom of the iPad via screws and a cable. This step detaches the antenna from the front panel, ensuring that when you remove the panel, the antenna will not be damaged.

    Be extremely cautious on this step! I did it wrong and my antenna went to !@#$.

    Lars Lien Ankile - Yanıt

    Also once it is unattached from the front panel, if the antennas adhesive touches the glass again it can re-adhere to front panel and may rip apart after all. Keep a close eye on it or leave a pick or card in there to prevent it from re-sticking.

    • Continue releasing the adhesive along the bottom of the iPad, pulling the opening pick out far enough to go around the home button, and re-inserting it to a depth of 1/2 inch (10 mm) once the pick is past the home button.

    • If the adhesive has cooled too much along the bottom edge, reheat the iOpener to warm the adhesive where you are working.

    • Do not heat the iOpener more than a minute at a time, and always allow at least two minutes before reheating it.

    • Continue releasing the adhesive all the way along the bottom edge of the iPad.

    • On iPad 4 models, insert the pick to a maximum depth of 1/2 inch (10 mm) in this area, to avoid damaging the home button ribbon cable.

    • Leave the opening pick wedged underneath the front glass near the home button.

    This should include details about the Home Button Ribbon Cable. Unlike an iPad 3 (which doesn't have this cable) the iPad 4 has a Home Button Ribbon Cable that runs along the left side of the Home Button and is adhered to the glass. If the guitar pick is inserted too far (more than 0.5") it is possible to damage or sever this cable.

    • Slide the opening pick along the top edge of the iPad, pulling it out slightly to go around the front-facing camera bracket.

    • The adhesive along this section is very thick, and a fair amount of force may be required. Work carefully and slowly, making sure to not slip and damage yourself or your iPad.

    • If the adhesive has cooled too much, replace the iOpener along the top edge and continue working. If the iOpener has cooled too much, reheat it.

    • If the opening pick is getting stuck in the adhesive, "roll" the pick as shown in step 9.

    +1 on the right 3g antenna - it is adhered to the glass and I cut right through it with the opening pick. The replacement included adhesive to re-stick it to the glass, so this is a definite feature of this antenna. This is a thin film similar to the wifi antenna, so maybe going around it at a shallow depth from the corner to the camera and then returning to the corner slightly deeper would allow you to separate the antenna from the glass without damaging it.

    The GSM component is glued to the screen with different adhesive (more like glue). I managed to not damage this but it was really tricky. The guitar pick is too thick and weak to release this from the screen. Id recommend you wait until you lift the glass (future step, NOT NOW). Then, with a good light you'll see the white plastic adhered to the glass. A thin metal pick or exacto is needed to patiently cut & pry your way through the adhesive. Careful of the camera as your pulling in that direction.

    There is an error in the red text in this step. It says ‘The digitizer cable is located approximately 2" from the bottom of the iPad’. The next sentence says .. ‘Stop sliding the pick when you get ~2.25" from the bottom of the iPad.. This will slice and ruin that cable. The last sentence should read ‘Stop sliding the pick when you get ~1.75" from the bottom of the iPad.’ so you stop cutting glue before you get to the digitizer cable.

    Be very careful when pushing the guitar pick around the corner of the power/volume buttons. The ribbon cable for these buttons may be stuck to the adhesive and break when lifting the screen or when sliding the pick along this area. I have done 4 iPad 2 repairs and at least one of the delicate components do not make it. I would recommend ordering a wi-fi/bluetooth antenna, bezel with strips, and a power/volume cable. It is nice to have a "just-in-case" part or two, they are very inexpensive. I noticed that the I tended to break one of these delicate components when the screen was shattered in the area of those components.

    thetechandtutor - Yanıt

    I absolutely severed this cable when loosening the adhesive around the volume button area. There is really no way of knowing if this cable somewhat elevated from the frame and therefore susceptible to being cut, and it happens to be right where one starts to remove the face with the guitar picks. The cable is directly in from the down volume button, so be extra careful not to put the guitar pick in too far in this area. I recommend buying a power/volume button cable just in case. Replacing this cable is also not easy, but doable. Just try to avoid doing it.

    nickmalmquist - Yanıt

    At this point it is a good idea to get the packing tape back out and wrap it around 2 or 3 of your fingers making a circle with the sticky on the outside. Make it loose enough you can place your fingers on the table surface to the side and pull your fingers out. When you remove all the tiny parts/screws in the next steps put them on top of the tape so you know exactly where they are when you need them

    • Holding the iPad by the top and bottom right corners, rotate the front glass away from the iPad.

    • Be careful of any adhesive that may still be attached, and use an opening pick to cut any adhesive that may still be holding the front panel down.

    • During reassembly use a microfiber cloth and compressed air to clean any dust or fingerprints off the LCD before reinstalling the glass.

    Check to the right of the Home button to see if the wifi/bluetooth antenna is still stuck to the glass side or has released. If it is still stuck to the glass use the guitar pick to carefully scrape it off. If your goal is to replace the antenna, then you needn't be so careful.

    Be very careful not to touch the LCD. It's a pain to remove smudges. One thing that might help when you need to hold it while reattaching it during reassembly: attach a small suction cup to the metal side. That way you can avoid touching the sides where your hand might slip to the LCD side.

    Go slowly as you lift up the glass and be sure that you are not tearing a ribbon cable. When I lifted the glass the digitizer cable was torn and unusable.

I don’t know if anyone would have the luxury of being able to remove a screen in one piece, the ipads I've fixed have been completely smashed pretty much all the way around the outside of the lcd underneath. I used this guide to know where to watch for cables etc - very helpful. I end up using a window scraper/razor to scrape off the glass shards/adhesive around the edge. Glass shards/dust all over the lcd is easy enough to get off but cleaning the lcd after that is a real pain. Does anyone have any suggestions how to clean the lcd properly?

    When reassembling the glass, align the camera first. On the back of the glass there are two pins on the metal camera frame.

    +1 to Luca’s comment. This deserves a RED NOTE for reassembly. I probably just destroyed my new wifi antenna due to not having a reassembly call out for alignment of the screen.

    The pictures here are very misleading. The ZIF lock tab is towards the back of the connector - opposite to where the cable comes in. you flip it up and over. The picture here does NOT show the lock tab released! when replacing make sure the white lines go right into the connector - you should almost not see them anymore.

    Mark Smith - Yanıt

    As Mark Smith noted the lock on the ZIF connector is at the BACK of the connector, the side FARTHEST from the cable. Put your spudger or opener at the back of the connector and gently pull up while pushing toward the connector. The black bar at the back of the connector will pop up and release pressure on the cable.

    Awfki - Yanıt

    The ZIF connector lock is almost impossible to see in the pictures, and even tough to see when you're looking at it. It is a really thin black bar with a hinge on the long edge. As Mark Smith and Awfki stated, pull up gently on the long edge that is opposite the ribbon cable. When inserting the new ribbon cable be sure to get the cable lined up, then push in straight and evenly.

    robertmhussey - Yanıt

    It IS possible to replace these connectors through a combination of hot air, microsoldering, experience, and talent (full disclosure:I sell replacements on eBay) but quite frankly, it’s a…it’s very difficult. Hiring a technician experienced enough to do it confidently and well will (should) cost you almost as much as the device is worth.

    So try the methods (like tape) that thicken the cable slightly at the point of insertion, so its contacts will make strong downward contact with the connector’s. Then tape the cable down well to keep it from pulling out.

    These solutions rely on recognizing the latch and breaking only it, so the above comments noting the latch’s location are essential.

    Bonnie Baxter - Yanıt

    FWIW, the second picture does show the connector’s latch in the “open” position. If what you see at the edge of the connector farthest from where the cable inserts is black, (first picture), the latch is still closed. If instead you can begin to see the metal pins (second picture), it is open. When open it is not even straight up—it is at perhaps 75 degrees from the closed position. Don’t open it too far or with too much force, or the latch will break off.

    Bonnie Baxter - Yanıt

    The same happened to me. While unplugging the cable I have broken the lock. I realized it only when putting everything back in place. After several attempts I noticed that if I pressed with a finger where the lock was the LCD worked.

    So, I inserted the cable and taped it so that it doesn’t slip out. In the iOpener kit you get some transparent plastic cards (not sure what are they meant for). I cut 2 small pieces the size of the connection and taped them down firmly.

    put everything back in and it worked.

    The lock is there just to make pressure on the connection.

    • If present, remove the piece of electrical tape covering the Wi-Fi antenna, speaker cable, and home button ribbon cable.

    If you’re replacing a battery, you can skip most of steps 34-49. You need to loosen the logic board to take the battery out, but you don’t need to remove it, nor do you need to disconnect all those other items. This is partly about saving work but mostly about avoiding many opportunities to break things. Before you start the following, study steps 46, 47, and 50.

    You must take out the 7 screws shown in step 47. One of them is covered by the piece of tape described in Step 46, so pull that off first. The screw marked in orange also holds down the power terminal from the battery. You can see the tab in the photo for Step 50, at the top of the battery, and that hole in the tab is where the screw goes through.

    (to be continued)

    Brian Pickrell - Yanıt

    (continued) Then pry the battery loose as described in steps 50 and on, except that you’ll have to reach in from the other side since the logic board is still in the way—this should not be a problem. I did it with a kitchen spatula and liberal use of the iOpener from beneath to keep the adhesive warm. Once the battery is all loose except for the power terminal tab, rock the logic board back (away from the battery) a teeny amount, just enough to get the spudger or spatula in under the tab and break it free. Then pull it out and put the new battery in such that the screw hole in the tab lines up, and screw the logic board back down.

    Now, all you have to put back together is the LCD, plastic bezel and touchscreen.

    I found it easier to remove the 7 screws first in step 42 then gently pull the logic board towards you freeing the SIM board cable.

    This cable is really fragile, I found it easier to flip the retaining flap then remove all 7 screws in step 42 then gently pull the logic board toward you freeing the SIM board cable.

    Rich1981 - Yanıt

    For me, it was impossible to accomplish this step without first removing the 7 screws from the Logic Board and disconnecting the Logic Board connectors (Wi-Fi, Speaker, Dock/Lightning) at the bottom. Then, I could slide the Logic Board downward just enough to pull free the SIM cable. When reassembling, I attached the 3 antenna connectors first, then the SIM cable, before installing the 7 screws and Logic Board connectors (Wi-Fi, Speaker, Dock/Lightning) at the bottom. Went a bit easier.

    • Disconnect the following connectors from their respective sockets on the logic board:

    • Wi-Fi antenna cable

    • Speaker connector cable.

    • Dock/Lightning connector cable.

    • There may be a piece of black tape covering this connector. Remove it with tweezers.

    • Make sure to pry underneath the connector and not the socket itself. Prying on the socket itself may cause severe damage.

    This was an ambiguous step. The Dock/Lightning connector and Wi-Fi antenna cable lift off fairly easily, but the Speaker connector cable does not. I ruined the existing Logic Board at this step. Not an emotional event, as I was replacing it, anyway, but showing how the connector looks, lifted out of it’s socket, would have helped. What tool did you use to pull/lift the connector from it’s socket? Prying from under the wires just stressed the wires, and I had to stop that attempt for fear of damaging the connector. Once I ripped the socket from the Logic Board, I was able to pry the two apart with my fingers, and had a better understanding of how to connect the Speaker cable to the replacement Logic Board. Sometimes these connections slide together, sometimes they’re pressed down into a socket connector. Do one when the other was intended, and you ruin things. You fell short, here.

    it would be helpful to show the image as to how to pry speaker connection cable.

    ian - Yanıt

    All connectors are pressed directly into the logic board (in the negative-Z direction). Use a spudger or, with extreme caution, tweezers, remove the connector straight out and away (plus-Z direction). Perform leverage as close to the connector as possible, to reduce any risk of wire damage. The dock/lightning connector is rectangular and centered in the depicted area highlighted in yellow.

    I applied some heat with a fan to the connector and pried him softly up from the left to the right. My first ipad went to !&&*, but with my workaround the second one was saved.

    Nils Grobys - Yanıt

    For the speaker cable, the connector needs to be lifted straight up to be released. The connector actually fits within a raised socket that surrounds it on three sides (up/camera side, and left and right sides). For this reason, don't try to pry directly from the left, the right, or the camera side, because you will actually be prying the socket rather than the connector. I used a pointed metal tweezer to pry on the bottom right corner immediately next to and just underneath where the wires connect. The socket popped off immediately with little force.

    Not showing how the speaker cable comes off is a serious oversight. The connector lifted off logic board. Disappointed. Everything good until that critical point. And then, you don't have logic board in stock.

    Vincent Martinez - Yanıt

    Another another vote for needing more information on how to disconnect the speaker cable. That is a major oversight, and on my iPad 4 it didn’t pop off easily either, probably due to age.

    • Remove the following seven screws securing the logic board to the rear aluminum panel.

    • Six 2.1mm Phillips #00

    • One of these screws, at the top of the logic board, is tucked beneath the headphone jack assembly cable. Take care to hold the cable out of the way while removing and replacing this screw.

    • One 2.5mm Phillips #00

    Be sure you follow step 37 and free the headphone jack ribbon cable. I missed that step and found myself puzzling how to get the rightmost screw on the logicboard.

    • Holding the logic board by the side nearest the dock connector, carefully pull the logic board toward the bottom of the iPad.

    • Flip the logic board over, minding any cables that may get caught.

    • Using the tip of a spudger, remove the three antenna connectors from their sockets on the logic board.

    Follow these steps for both a speaker replacement, and then a touch screen replacement later on. However when I had to replace the battery, the cable between the main part of the logic board, and the LTE cellular component got ripped. Now the ipad will only stay booted for 1m30s before it reboots itself in a continuous loop. Has anyone seen this problem before?

    I followed all the steps and I was able to replace a battery and a the screen on my daughter ipad3 but when plugged back in, the ipad goes in a resetting loop. turns on for 7-8 sec turns off for 7-8 sec. I tryed to do a hard reset but the ipad will not stay on to be able to move it fro the wall to the computer.

    I did not shattered or destroyed any cable (as far as I know) and I opened and checked the connections 3 times now and nothing changed. The old battery got destryed in the process so I cant try it on to see id the same things happening. Please somebody help me!

    laura - Yanıt

    This same thing happened to me. I ended up holding the power button and home button down until the iPad rebooted. When it powered back up, it was working correctly.

    If new battery was criticality low in charge, it will boot loop. Put iPad in freezer for 30m and immediately plug to charger when you remove it. Reason: too low % on battery after repairs won't allow to boot so loop occurs and you can't charge a device in a boot loop. Freezer forces an emergency shutdown and will stay off till temperature is normal by then you should have enough charge to boot. Hopefully this helps!

    The 3 wire connections to the underside of the system board are identical, so you might want to color code them before removal ... get them back in the right place, I think they are for the left and right GSM antennas and maybe the front camera?

    Peter Dearnley - Yanıt

    I did not have to remove any of the three antenna connectors while removing the battery just take your time and you can leave the connectors connected.

    Rich1981 - Yanıt

    I wish I did what you did.

    Dear Peter, does it really matter which socket the 3 wire connections were connected to? I did not mark/color them with any sign!

    Alexandre Bernier - Yanıt

    Well…. i am at this stage now, i have lifted the 3 x wire connectors…and have not colored them… I am noticing that the cables leading to the connectors are of different lenghts : the shortest can obviously only fit on the connector which is the closest to the edge of the small board… and the longest should be for the connector which is the furthest away from the edge….

    ptouboul - Yanıt

    When reconnecting, getting them to stay in place is a pain. Any suggestions?

To reassemble your device, follow these directions in reverse and use our iPad 4 CDMA Front Panel Adhesive strips guide to reattach the front panel.

I was replacing the lcd and digitizer for this model and lifted the battery connector a bit with a piece of plastic,as to not shock either when I reinstalled them. The shim tore the ribbon cable to the CDMA card. I found an iCloud locked model in the junk pile and re soldered the connector on the line up holes on the logic board side and the alignment windows on the CDMA side. I still get a searching prompt for about 5 minutes and then it reboots like clockwork. What have I done wrong?
