Bootloop after few drops of water (TWRP recovery and bootloader working fine)

[bbijoch]

Hi,

I have unlocked MI 5S Plus with TWRP 3.1.1.0 recovery and custom ROM lineage-14.1-20170518-nightly-natrium-signed.
Few days ago some water got inside the phone, just some (the phone didn't fall into the water). From that time I have a bootloop.
I can't boot the system, but TWRP recovery and bootloader mode is working perfectly fine.
I treid many times to load different zip ROMs from TWRP.
I also tried stock rom *.tgz via bootloader - stable and dev - still bootloop.
I opened the phone and cleaned the PCB with isopropyl alcohol, but no change.

What else can I do to get rid of bootloop and boot the system?

Regards
Bernard

have you tried running FSCK on the partitions? that may help determine if the chip is bad.
Failing that, we'd need some logcat or something to diagnose the problem. Can you get a logcat using ADB during boot?
