[Q] Help - HTC One is not charging topic

Hello,

I've searched the forums but I could not find a solution for the issue I have with my HTC One.

Since I left it fully discharge some weeks ago, the phone won't charge anymore unless Fastboot is disabled and the phone is off.

So far, I've tried the following:
- Factory Reset
- Re-flash the ROM (from an older ARHD to ARHD 31.6)
- Start phone in Safe Mode
- Hold down Power + Vol Up + Vol Down for 2 minutes
- Clean the USB port using compressed air to remove the dust

I don't know what else to try, I can't even tell if it's a hardware or a software issue.
Also, my phone is *not* being recognized when I plug it on my PC (Windows 7), so I can't use adb or fastboot.

My HTC One is the ATT variant, S-OFF, running ARHD 31.6 (4.3), below is the beginning of the Bug Report generated by the phone using the Developer option:

The phone is not on warranty anymore.

Thank you!
