iPhone X water damage salvage. Powers on now but boot loops
So my friend asked if I could try and fix his iPhone X that got put through the washing machine. I told him I've never done this sort of thing before -- mostly just screen and battery replacements. He said it's ok because if I cant fix it he can't afford the repair bill a shop would charge anyways.
After fully disassembling it and meticulously cleaning the connectors by hand since I dont have an ultrasonic cleaner, I finally managed to get it to power on but its stuck in a boot loop.
From what I've read, this is normally caused by not enough power going into the device right? My battery testing board shows the battery is okay, however I did notice the battery socket on the logic board looks a bit dark. I fear he may have fried it.
Is it realistic to replace this socket or should he just buy a new logic board? His current board is 256gb so it would really be a shame if it cant be salvaged.
Anyone have any opinion on what the best path forward is at this point? Thanks :)
