Great! Could you show me any thread/guide for flashing from fastboot?
thanks.
No Guarantee, do it at your own risk!!

Download the file behind the keywords "complete firmware", it's version 6.04.1700.19 (the latest one). READ EVERYTHING IMPORTANT IN THAT THREAD FROM THE BEGINNING (NOT ONLY THAT POST)!
Boot your phone into bootloader.
Switch into FASTBOOT mode.
Connect your phone via USB with your PC.
It must be shown "FASTBOOT USB".
On your PC use "htc_fastboot.exe" instead of standard "fastboot.exe" (search in this forum and you'll find it).
Switch to RUU flashmode:
> htc_fastboot.exe oem rebootRUU
Now flash the firmware:
> htc_fastboot.exe flash zip M7_UL_GPE_Firmware_6.04.1700.19.zip
htc_fastboot runs automatically two install cycles (first is hboot-preupdate only). With standard fastboot you need to install twice manually.
Now reboot into bootloader again, and — tadaaa — your GPE firmware is there.
> htc_fastboot.exe reboot bootloader
That's it.
