I want to install B2G on a Xperia Z3. The build was ok, I get the image-files. Now my problem is the flash process. I tried to unlock the boot loader with fastboot and Sonys unlock code, but fastboot return “FAILED (remote: Command not allowed)”. I looked in the “service info” “rooting status”. There I see the message “bootloader unlock allowed: no”. Anyway I tried to flash the images to the Z3, but it fail also with “FAILED (remote: Command not allowed)”.
Exist a other way to install B2G on the Z3? Thanks for ideas and hints.
