iPhone 7 Plus does not charge or connect to computer after cleaning
My iPhone 7 Plus recently was dropped in salt water. I continued to use it for about a day (it's supposed to be good for 30 minutes in 1m of water right!?!?) until it went into a boot loop.
I opened it up and cleaned it out. There was some corrosion at the top in the rear camera socket and antennae. But all seemed to be contained to this upper area. No signs that it got near the Logic board. Once satisfied with cleaning it, I powered it back up and was able to charge it. Only thing was that it was getting pretty hot pretty quickly.
So I then soaked the logic board in 99% isopropyl alcohol for about 15 minutes and then let it dry overnight. I re-assembled it and it works perfectly now... Except it does not charge or be recognized by a computer.
The phone however recognizes that it’s got a cable attached to it as it will power on when plugged in (if off) or if it’s on it will vibrate and the notification saying “Unlock iPhone to use this accessory” pops up.
I have re-seated the lightning connector to the logic board a few times now. It’s not that. I cleaned out the lightning port and the lightning connector. Nothing. I am stumped. I’ve come to the conclusion that it’s either:
- Lightning port is corroded beyond repair or the lightning module is busted;
- Dunking the Logic board fried the Tristar/U2/IC chip; or
- There’s more damage from the salt water that I can’t see.
Took it to a local repair shop and we’re going to try a new lightning module tomorrow to see if that works. If not, I’m not sure what to do…
