HTC One M8 - Stuck on the HTC logo

[AC Question]

Hi,
My phone is stuck on the white screen HTC logo.
I've already tried several things: fastboot, recovery, factory reset, etc. None of them worked.
Anyone has a solution for this?

Context:
I dropped my phone in water. This problem happened after that. Maybe while I wiped the device with a cloth I pushed a combination of buttons that caused this.

Or maybe just water damage, with or without impact damage depending on the depth of the water. See this:
