- Your device must have an unlocked bootloader ;
- You need to boot to bootloader and ensure that you device is detectable by your computer with
fastboot devices; - You need to have the images in the working directory ;
- Run
./flash.sh.
You may need :
- to run it as root
sudo ./flash - to run it twice to flash slots a and b
- to erase userdata
fastboot -wafter the flashs
If you see the warning that shuts down the phone after the 30 seconds, do not forget to press the power button to boot.
