After all was done I had 1 spare part that I did not know where it came from.

Now when I talk to my mother I hear my voice echoed realy loud.

I am sure it has to do with this part.

Please help, I could not find it even on exploded views.

I have a iphone 4s and screen cracked ages ago decided to repair it finally.

bought a replacement screen and it arrived, i opened up the phone and tried to fit it and turns out they sent me a iphone 4 one not 4s so it didnt fit, i tried to connect the flex cables anyway and it didnt work that well.

anyway next day bought another screen for 4s this time and got it fitted. it turned on and worked well for the rest of the day and then at night it turned off and hasnt come back on since.

I have charged it and the sound toggle on the left top makes the phone vibrate and i can call it and it will ring.

at a few times when i played around with the charger and stuff the screen lit up for a while, like a white hazy border inside the screen but nothing to resemble the wallpeper or homescreen.

the backlight doesnt seem to come on at all but i think i heard the keyboard type once but havnt been able to confirm since the screen isnt working..

i can disassemble it and reassemble it but i dont think it will help.

i have tried to undo and re seat the lcd tabs (two of them) but doesnt make a difference.

do you guys think it might be the connection on the motherboard thats the problem and not the screen?

This thing is important because I’ve got an iPhone 4S with 9.3.5 iOS and I noticed that this iOS is really slow, so I would like to downgrade to iOS 7.0 but I noticed that this is not possible because Apple didn’t sign iOS 7.0 or 7.0.x.

So, what is the solution? If Apple didn’t sign an iOS, but if I’ve the file of iOS 7.0.x is possible with another software downgrade actual iOS to iOS 7.0.x?

Thank you in advance for reply.

For starters, I have an iphone 4s here that has been dropped in a HOT TUB, and was left there overnight until found the next morning. Im guessing the hot tub had chlorine in it too, not sure. It had been taken out that morning and was taken straight to me,

Now, bearing in mind the fact that despite nobody attempted to turn the phone on after it had been dropped into the hot tub for several hours, it still had not been turned off manually, so the power had obviously failed and the phone shut down whilst it went for a little swim.

However, I disassembled phone and submerged the logic board in a container filled with 99% isoproyl and waited about 5 minutes. I then took it out and used a tooth brush and gentley brushed every area of the board, including underneath the metal shields. (I was careful whilst taking these off and then lightly brushed the chips)

I also cleaned every contact of the phone inside the housing including the LCD digitizer etc.

The only signs of corrosion that you can visually see is on some of the screws, nothing else, the logic board now looks clean.

I then replaced the battery and the power button flex cable, cause 9/10 the flex cable fizzles out just as much as the battery.

I assembled only some parts of the phone to save time, so all that I had connected to the logic board was the battery, the power button flex cable, and the two digitizer ribbon cables...just so that I could see if the phone could gain power.

I tried my luck, and WALLA, after pressing the power button the screen came on! I thought I had fixed the phone because the apple logo came up, an then the main screen came up where you enter your pass code.

I left it out for about 15 minutes and it was working fine. Until I decided to check to see if the camera was working, and without turning off the phone and I went ahead and just connected the camera connector straight to the mother board while it was still ON! (bearing in mind that I have done this many times with my actual phone whilst the phone was still on and this never caused a problem) Until then all of a sudden the screen went BLACK and I have not been able to power it up ever since!

What went wrong ???

So to summarise,

I cleaned the phone and logic board with isoproyl.

I replaced the battery

Replaced the power flex cable

I managed to power up the phone temporarly

I then connected another component whilst phone was LIVE, (naughty I know)

and then nothing, black screen. Still is now.

I couldn't possibly imagine that I blew the motherboard as I connected the camera did I? I mean, iv done it many times on my iphone 4 without turning it off first and nothing bad happened. So I am guessing that a different fault may have happened coincidently as I plugged in the camera. But none the less, still no power.

wtf#ifucked.
