Writing phone firmware without real necessity is at your own risk.

Downgrade may lead to phone damage!

Please, make sure the phone's battery is fully charged.
Disconnect all other devices from the computer (including phones,
modems, etc.) and close all other running programs.
To avoid errors in the flashing process, use a clean PC (without any
installed drivers for other Qualcomm-based devices).
You should not run any other programs or attach new devices to your
computer during the flashing!
