[Q] D800 power button not working

Problem: Power button is not working on my D800. It doesnt turn on or off when I try to click on it. If the phone is off, the only way to turn it back on is plug in the USB. However, the phone still reset if I hold it for like 10sec. I can't get into recovery by holding the power button and down.
History: The phone was recently bricked into qhsusb_bulk mode. I followed the instructions on this board and re flashed some files. I think this is when the power button stopped working. After that I used LG Flash tool to restore to stock 4.4.2.
If anyone can help, I would very appreciate.

Hard key map

Hi,
I'm having issue with a GT-I9505 S4 phone after droped it in the water, key combinaison to turn the phone up are altered, if i only push "power" button, the phone boot in recovery mode, if i push "volume down + home + power" the phone boot android in normal mode.
I've tryed to re-install samsung stock rom, the problem persist, i've tryed to install cyanogenmod 12 and problem still here too.
It's seem the water have corrupted a firmware (maybe qualcomm's firmware?) so i don't find which one !
When powering the phone with "volume down + home + power", all work just fine !
I've checked if some buttons are stuck, so it's seem they work fine too.
Partition mapping seems good, using adb to restart the phone in recovery, download or normal mode work fine, so if i try to reboot from android's menu, it boot in recovery mode.
Does anyone have some help or infos to help me to solve this problem?
Is it possible to "re-map" the key combinaison for turning up the phone?
Thank in advance
Kev
