What caused my iPhone 5s to brick)?
I purchased this iPhone 5s used in January 2017 for 100 dollars, and at the time it worked great. I later dropped it in the lake by accident, but recovered it and put it in rice. It worked afterwards, but the vibrator motor glitched for a day or two, eventually correcting itself. It has been 1 1/2 years since and everything was working, until the vibrator motor stopped. Since i recently repaired my iPhone 5’s battery, I figured I could easily take it apart and reseat or replace the motor.
I disassembled the phone, reseated the motor, and then half-reassembled it. Bam! It worked again. I don’t think I reattached the screws inside but I may have, not sure. But I realized the flash on the back broke, so I took it back apart to try and fix it by reseating cables and such. I tried several times without success, and one time while trying to restart it again it just did nothing. Before this it had been starting fine and working normally even when I hadn’t totally reassembled it, but now there was a black screen with no responsiveness, didn’t even show up in iTunes.
I’m baffled as to what happened. I read that if I put the 1.3 mm screw in the 1.2 mm hole I could have broke the logic board and caused it to go into a boot loop with a blue screen, but it does literally nothing. I don’t think I ESD the board, because there’s plastic shields all over it. I did pull a bit hard on one of the screen connectors, but I really doubt that was the problem because everything was working fine after I did that until one of the times I turned it off and removed the screen again to inspect the flash. I also accidentally disconnecting the LCD when it was on, but again it seems unlikely that would break it. Does anybody know what I did and if its salvageable? I don’t want a new phone, the screens are too big for me, and replacing the logic board would cost as much as the phone’s worth, so I’d rather not. Thanks!
Update: I had a weird theory that leaving it alone for a week could potentially fix it. I was correct. I plugged it in today and it started up, working properly with the exception of the power button, vibrator and switch, and volume. I have determined that the connector for these buttons (FPC J2) is broken and needs to be replaced at micro-soldering levels, in other words I’m going to use assistive touch from now on because there is no way I’m buying a micro-soldering kit when there’s a 99% chance I’ll botch the repair anyway.
TL;DR Leaving an iPhone to sit and then charging it will fix it sometimes. Because that’s Apple. If anyone knows how I can fix the connector or jimmyrig it, let me know. If you think its safe enough to attempt micro-solder without frying it, (I’ve never done it before but price and time isn’t a concern, I just don’t want to break it since I got it working well enough), let me know. The connector is iPhone 5s J2, this is what it should look like:
and this is what mine looks like:

As you can see I damaged it quite badly, and the flex connector and everything attached would need replacement as well. Unless I could just do some sort of jumper set up with 18 micro solders connecting the plates to the connector wire. Let me know your thoughts in comments.
Es esta una buena pregunta?
