iPhone 6 Plus - pulls charge, but no boot
I have an iPhone 6 plus with water damage, it pulls .5A (it drops to .01 every few seconds then back up) but doesn't boot. I cleaned the board and checked for shorts and found nothing. I'm fairly new to board level repairs, so I'm mainly looking for what steps I should take from this point to narrow down the fault
Is dit een goede vraag?

If you are new to board repair the first rule is to rule out a parts issue.

@imicrosoldering The first thing I did was removed board and used new battery, new screen, and new charging port. It's definitely a board issue, just not sure the next steps to take when there's no short. I hooked up battery and tested voltage throughout the board, got 3.7 throughout the main power rail, where should I look next? I also replaced tristar which didn't resolve anything, which I expected since it already pulls a charge. Also plugged into pc to see if it was booting to dfu, but that was a no go as well

@shadowsuave Have you tried an update with iTunes?

@imicrosoldering it's not detected by iTunes

@shadowsuave You will need to put the phone into recovery mode or if data is not important DFU mode.
