[One (M7) Q&A, Help & Troubleshooting] hallaj:
help needed with what I think is a bricked HTC One M7

Hi, I hope someone could help me out here. Let me give a bit of background on the event :)

The unit I have is still a stock unit, but just ran out of warranty.

1. Phone went into a boot-loop cycle until battery drained.

2. Hooked it up to the charger (USB to wall and USB to PC) but nothing happens (phone looks in a turned off mode, temperature, cold).

3. Tried several suggestions that I read online:

1. Hook it up to the USB-Wall for 10 minunites, tried to power on, or even hold Volume Down + Power; nothing happens.

2. Continued hooking it to the USB-wall for a longer period (4 to 5 hours) and tried both again. Still, no luck.

3. Hooked it up the my PC, and tried the above. Nothing happens.

4. Hooked it up to my PC (and glanced into dmesg) (I'm running Fedora 20) and saw that my device was detected.

5. Thinking that it may work, I tried adb, but the device wasn't detected.

6. Thought it was probably becuase it was detected as USB modem, so then I tried the Volume Down + Power button combination, and a new log appears from dmesg.

7. Noticed that my phone was restarting itself, even in that mode. Adb still doesn't show the hardware, I suppose it's because it's in a power cycle mode.

Based on the events above, could someone help me in getting it back to life? Or it's just completely dead? I'm tempted to try the HTC center again, but my warranty expired and the center is too far from my area.

Please, anyone with suggestions or ideas, do share it with me as I've completely ran out of ideas.

Thank you :)
