s6 motherboard boot loop/freezing after water damage repair, hardware
Hello, phone had minor water damage, not fully submerged, and customer brought it in with no power.
After cleaning w/ 99% isopropyl alcohol and a run through the ulrasonic cleaner, it will power on and boot to samsung logo, download mode, or recovery mode.
Tried flashing stock rom (older versions and then newest firmware) and no change.
At one point I was able to get it to boot normally but it rebooted after a minute or so. Most times it freezes on the samsung logo, sometimes it reboots on the samsung logo.
Tried many different combinations of factory data reset, clear cache partion before and after flashing stock rom.
So it is a hardware issue. Motherboard does not have any hot spots nor corrosion visible under 10x.
Any help or advice troubleshooting this on s6 or s6 edge appreciated. A google search turns up nothing substantial, although some others have similar (unanswered) questions
I am comfortable micro soldering, replacing components and wanting advice on how to troubleshoot this repair
