My HTC One just crashed (hang) two hours ago. I didn't do any 'dangerous' manipulation (as ROM flashing etc.) -> it just stop working. Now it is stuck with a black screen and the home/back keys are light up.
I tried to do a soft reset (hold the power button more than 20s), a hard reset ((hold the volume down and the power button more than 20s), hard and soft reset with a bright light, but nothing work. I am a bit afraid for my phone
Is there any trick I can test to reboot the phone? (It is currently sitting in my freezer in order to accelerate the battery draining -> yes I'm desperate).
EDIT: The phone is not recognize by my laptop (no event with dmesg and lsusb see nothing...)
