How To Repair Logic Board Water Damage Iphone 6s
I'm enlightened of this question, however information technology doesn't solve my problem.
Today I bought a water damaged iPhone 6 at a expert price, thinking that since I am pretty decent at repairing iPhones (and fixing water damaged ones before), that I should be able to fix it without whatever issues and take a working iPhone 6. Still, after doing my usual "accept the while thing apart and clean information technology with isopropyl booze" h2o damage repair routine that has worked well in the by, information technology nonetheless won't turn on or even be recognized past iTunes.
This iPhone 6 has been dropped in a pool, whether it'due south chlorinated or saltwater, I don't know. I do know that information technology has been around a week since then, the seller informed me.
I have tried (in order):
- Cleaning with an alcohol-soaked fabric multiple times
- Taking a spudger and gently scraping around the chips
- Soaking the board in alcohol and when that didn't work, cleaning it with a toothbrush while submerged in alcohol
- Running the logic board nether warm tap water, so submerging it in booze and cleaning with a toothbrush once more
In each case, I made sure that the board was dry before testing.
Edit: I decided to break out the soldering fe and removed all three shields from the logic board. After removing the first one (the one below the SIM slot), the iPhone came on, merely was stuck in a boot loop. However, afterward removing the second one (on the dorsum), the phone no longer comes on, and cleaning the behind the third i (covering the A8) didn't aid either. Strangely, sometimes when I connect the iPhone to the wall charger, if I press the shield upwards where information technology should go, the Apple logo flashes once and then goes to black, though the LCD is on. Whatever ideas on what to do adjacent? Can I use computer thermal paste on the A8 chip and heat sink; is it the same thing as what's already on it?
Whatsoever ideas on how to gear up the board?
Besides, it's almost definitely the board, as I've used multiple lightning docks and digitizer assemblies for the iPhone 6 that I had lying around and bypassed the battery by plugging the iPhone direct into the wall.
