So I thought maybe the battery is faulty. I changed again a new battery and phone keeps restarting if I try to log in to my Apple ID or update it. Battery does not show health and this time it won’t charge more that 27%.

All I can do is perhaps change a charging port. I don’t know the history of the phone and I don’t know how to check or fix problems on board.

Any advises or should I just toss this to trash bin?

n00b here!

I got this iPhone 7 Plus with qualcomm.

I give it direct power, It draws 0 current.

When BUTTON_POWER_KEY_CONN_L shorted to ground it draws 0.43A then ranges between 0.2A -0.4A

When in phone housing, it is not detected by itunes, I also tried with other housing.

Please guide!

Thanks!

After a few minutes, wifi will work but will be bugged. The phone says the wifi is off while it’s on.

When I restart the iphone wifi is greyed out again. Does anyone have experience with this? The second phone in 2 weeks that have this problem. First time the customer came back and saying her wifi was broken again. I reset the network settings and it worked the first time so I didn’t read too much into it and didn’t charge her money.

Sounds like a wifi chip problem, but I wanna make sure. Repairing the audio IC isn’t an issue but I don’t wanna make things worse after heating up the board when repairing audio IC.

EDIT: Just repaired the audio IC and left it like that. The customer is aware wifi can fail any moment but didn’t want to pay for the repair. Can’t do anything else than that.

I have dropped my phone from about 40cm in height from the table onto the carpet. The screen when picking up slowly faded to black and it never lit back up. It is worth noting the screen has not a single scratch nor crack, same for the phone. It landed quite soft and the home button does still work when pressing.

Tried restarting, DFU, all software options but without any resolution. Then opened it with the iFixit tools & guide as I read in a lot of places it could be just a simple dislodged screen cable.

I have not noticed anything particularly loose inside but I followed the guide anyway and disconnected & re-connected the two screen cables several times but no resolution. The Taptip engine/home button still works masterfully.

Does anybody have any suggestions on how to proceed now? I have already another iPhone so it is not really that I want to use it, I just desperately am trying to get to my data as I also was unable to transfer the backup I made some time ago onto my new iPhone. I really just care about the data, which is why buying a screen replacement would be the last step to undertake knowing I have another phone already.

Many tthanks in advance!

KR,

Kevin

I have an iphone 7 with vddmain short.

The phone story is very normal, client said, he just put out the phone from his pocket and find it off.

I check it with DCPW, they show.

1,2 Volt and 1.4 Amp.

(my DCPS voltage down automatically when i connect short phone and it i manually up the voltagage button, nothing happen and remain same.

The back lower part is hot.

The hottest ic is q2101 and Tigris u2101.

I put out both of them and check the short present.

i change both ic’s but short remain.

Usually i check with Freez spray and always find the bad capicitor or ic, but in this case i cant find nothing strange.

Anybody has a suggestion plz?

Thanks

EDIT: DFU mode also did not give any success or evidence of progress in any way.

Any help would me very much appreciated, as the phone is unusable and I'm out of ideas.

we have another problem facing us: iphone 7/7+ - if you are so unlucky to break your homebutton or sensor flex, your phone will not boot, it will just stay at the apple logo. You simply cannot just go changing them with aftermarket parts or OEM parts, it must be fully original (not chinese-original), which means 1. much, much harder to get, 2. much, much more expensive. This does, however, not effect screens, you can easily use the high copy grade - as long as the small parts are ORIGINAL! So, fair warning my friends, be very careful not to bust anything when taking the screens apart. Basically, Apple reinstated error code 53, but not as an itunes error, more as a phone that'll brick when booting. If you switch to original parts, it boots just fine again. Apple has not yet solved this in the latest update like they did touch-ic error on iphone 6S, and who knows if they will at all. Back in the day, they got convicted into removing error 53 (if you had aftermarket homebutton installed on ip6, your phone would brick on updating in itunes, until original button was mounted), as it was a violation of consumer rights, as Apple was making it possible, only for Apple to fix it. We are facing the same problem here, basically - and as i see it, there are 2 solutions: Apple will have to change this (as this haven't been a problem the since ip7/7+ release, but is a new thing in thread with ios 11), or we be very careful, and buy original parts when we mess up. My personal opinion: get a lawsuit going, so we get the possibility and freedom of using the parts we want (and the customers want in most cases, as it is much cheaper for them as well), back!

BTW, i don't know if this can be viewed as a question, sorry for that! This is basically just knowledge i've been researching, and passing on to you, so that you don't have to spend days looking for a fix that will not work ;)

Any recommendations for getting the chip cover to fit perfectly every time? Has anyone taken off the OEM chip cover and replace the non-OEM cover with it? Could you just pop off the non-OEM chip cover and simply place it in the small area inside the phone where it should fit and it'll naturally cover the touch IC chip without it actually being glued on? The 7 Plus phones have more wiggle room for this chip cover, so I've never ran into problems with that model.

just over night my iPhone is showing the apple logo (contonious, no blinking). I tried:

-new battery

- hard reset

-recovery mode

-DFU Mode

Just the DFU Mode helped a little bit. But in the end, it shows three different failures

- iTunes failure nr -50

-iPhone can't be identified

-iPhone can't be activated, because the iPhone doesn't send an activation information (i don't even know what that means :D)

Sometimes i can connect the iPhone with iTunes and it recognized the iPhone, but the display continious just shows the apple logo.

Thanks in advance for help.
