This is going to sound crazy but it works.
put phone under a bright light source
press and hold power
lights will eventually blink
phone will shut off

yes. It's necessary to overwhelm the ambient light sensor.

I read somewhere also that if you hold power button and volume up as well as volume down all at the same time for a few seconds when phone is frozen, it boots the phone like a pulling battery out reboot effect.

True, but there seems to be some kind of safety feature HTC built into the phone to prevent you from accidentally restarting your phone like that in say your pocket. The ambient light sensor is checked before the reboot will take place, hence the recommendation of rebooting with a light pointed at the sensor or at least in a brightly lit room.

thank you guys , this really works ...4 a moment i tought my phone is gone ...so keep up the good work :good::good::good:

I never knew that the phone checks the ambient light sensor before it reboots. I usually just hold the power and volume up button for about 10 seconds

---

Uh I just usually hold power until the back and home button starts blinking then it will stop to tell you the phone is off. I thought the guy who said the thing about ambient light was being sarcastic

and 9 times out of ten that will work, but for some reason, from recovery, or when old aroma would get stuck, it didn't, unless you held the phone under a bright light.

Confirm this is true!
I was stuck in the aroma when I was flashing the kernel. I tried for hours to shut it down (tried everything, like hold down for minutes, all combination of holding buttons, etc..) but nothing works. At last I found this post and followed the instructions...
Additional info: The Light sensor has to be stimulated for couple second (may due to some buffer on the sensor reading). The last time I succeeded when I pointed a LED light to the sensor for about 10 seconds and then hold down the power button.
Thanks gunnyman! (Say thanks with words and Thanks button! XD)

alternate method to holding down buttons
I had to find a way to restart the phone when it was in TWRP and frozen. This was caused by using an outdated version of TWRP and no combination of buttons or bright lights was working. If you have access to a computer and are comfortable using adb, this method worked for me.
1) Get and install the latest adb files. I use something called minimal adb and fastboot.
2) Connect your phone, open a command prompt in the directory where your adb is located
3) Type "adb devices" and your phone SHOULD show up
4) Type "adb reboot" or "adb reboot-bootloader" and the phone will reboot either normally or into the bootloader, whichever you prefer.
5) ?????
6) Profit.

thanks all, power and vol up and down worked like a charm

Hi there, am also stuck on frozen TWRP screen, all was well and good for a while but then my damn stock rom downloaded an android update over wifi between reboots (didnt notice) and applied it without asking and now TWRP is non-responsive to touch. Have tried following the above but for some reason now fastboot wont recognise the device, it just says device not found when i try the above (when booted into stock rom). Have tried booting into TWRP and pushing the recovery flash, at the moment its not working either (can get into and out of TWRP as described above). Is it pertinent that during the process i get "ADB server is out of date. Killing:*Daemon started successfully? I have updated android studio to latest but still get this message for some reason...Any help much appreciated. Just trying to get a working recovery so i can flash rom.

Maybe my question above is in the wrong thread? I can confirm that holding down both up and down volume buttons an then power does the same thing as taking the battery out in other models (restart).

Fastboot commands work in the bootloader / fastboot USB
adb commands work in TWRP / recovery
If you can get to the bootloader fastboot USB reflash TWRP or relock the bootloader and flash the same version firmware you have now again
and then flash TWRP

Hi cIsA, thanks for your reply and for distinguishing that after replacing the recovery with TWRP only adb commands will work. Havent had this problems with other phones I have modded. When you say get to the bootloader, one does that by holding down volume down and power no? That takes me to TWRP. I thought recovery and bootloader were the same. So this mean i cant run fastboot commands after installing TWRP? I have re-posted my question in the TWRP thread for this device as I think I may be off topic given the thread title.

try shut down / then power + volume down / this should load the bootloader not TWRP
from TWRP choose reboot bootloader...does this get you to fastboot usb ?
This is the bootloader
