For those who need the signed firmware, below are the Marshmallow firmware that I have. 


CID HTC__621

MID 0P6B11000 


How to install firmware :

  1. Install latest TWRP 3.0.2-0

  2. Download fw_6.20.709.2.zip 

  3. Download and restore 6.20.709.2

  4. After restore is complete, go to reboot menu then select reboot to bootloader

  5. Depends on where you put the fw_6.20.709.2.zip – must be in fastboot/adb folder (or anywhere if using system-wide adb/fastboot) – open command promt

  6. Run these commands

fastboot oem lock
fastboot reboot-bootloader

fastboot oem rebootRUU
fastboot flash zip fw_6.20.709.2.zip

you'll see ERROR/FAILED, repeat

fastboot flash zip fw_6.20.709.2.zip
fastboot reboot

Done … now you have stock Marshmallow.
