iPhone 6 can restore in recovery mode but nothing after that
I have a severely water damaged iPhone 6 which has corrosion on the top part of the board, the bottom part looks fine and not corroded. I have cleaned up as much of the corrosion as possible with 99% IPA but the display connector probably needs to be replaced and therefore nothing the screen is not working and does not display anything (although there could be another underlying issue). The phone is able to successfully restore in iTunes through recovery mode but does not show up in iTunes after that. As the screen outputs nothing, I cannot see if the phone has actually booted after restoring or is just bootlooping after that. I have transferred the logic board into the body of another working (but iCloud locked) iPhone 6 to test if the screen or battery were causing the problem. but there was no difference. PP1V8_LCM_CONN is outputting a stable 1.8V as it should and there is a normal amount of heat coming from the CPU and the baseband IC.
Is there anything I could do to diagnose the problem and find the issue? Any help would be greatly appreciated.
