sorry, firsts post were very confuse, i could not figure what version was currently installed on the phone
also, used tools and modes were mixed :
-
fastboot command is expected to be used in bootloader mode to unlock or relock the bootloader
-
included install script is expected to be used in bootloader mode for new install with
IMG-e-3.2-a14-20251022539005-official-FP4.zip -
when adb command can be used in recovery mode to update with
e-3.2-a14-20251022539005-official-FP4.zip
