[One (M7) Q&A, Help & Troubleshooting] ban19:
Hi Fellas,

Just Rooted my HTC One m7 UK 3G Sense 6.0 Android 4.4.2 using this tutorial: http://xdaforums.com/showpost.php?p=38933080&postcount=1 And after that it wont turn on, all the time in boot loop. Would Appreciate any help to move forward unbricking my phone.

1. Unlocking bootloader with HTC DEV went OK

2. Ive flashed CWM Recovery

3. I havent rooted the device, as it said that with custom rom it wasnt requiered (it may have been a mistake?)

4. Ive flashed "Android_Revolution_HD-One_71.1" through fastboot. Installation went fine, but at the end it asked if I want to ROOT the device, pressed NO. After rebooting the device it wouldn't go past the HTC Boot screen. Tried going back to Recovery, but it wouldnt boot.

5. I didnt install boot.img for this ROM

I reinstalled the ROM from External USB connected with OTG USB cable and this time flashes the boot.img, but it didnt help, does this rom need ROOT?

I flashed it again with TWRP Recovery 2.4 and it didnt allow access to recovery, then flashed with TWRP 2.7. I gained access to recovery but there were no more files in there, and I couldn.t access phone memory from PC. Then I tried running RUU from this tutorial: https://www.youtube.com/watch?v=C0G0hKY4P9Y But it dodn't work as it couldn't verify the signature.

FAILED (remote: 12 signature verify fail)

It doesnt show now, but I believe that the main was: 5.12.771.3

I found this RUU Stock ROM, but not sure if it is the right one https://mega.co.nz/#!s1o1jY6S!xKwJh0BALIBxdoo-n23KlHdlXkjeDnC6pAsBmFv8ags

I also have onother HTC, not branded:

If I get another HTC from 3 Network, is it possible to extract RUU from it?

Thank You all in advance, all usefull help will be rewarded.
