Fastboot don't work to re-lock BL. what can I do?
I have flashed stock ROM using TWRP recovery. Adb works but fastboot not
Oem lock is grayed in dev op.
Resolved: it was a cable issue
I've tried (clear data of weather app) but bug is still present. Changing the language to english (form italian) solved the problem but after a reboot the bug reappeared.
