That is very strange it is my phone lost in the setting the developer option. Why ?

@kugiigi I have passed the first grade ton unlock the bootloader. But yet adb devices dont make any thing. The phone is not recognized. And i don't enter the last command "fastboot flashing unlock_critical"

Hi,
Classic truble, i think, i'am stuck to unlock the fastboot mode. To downgrade to android 13. When i type "fastboot flashing unlock", nothing appen's, only "waiting for any device" in my term, although "adb device" command work.
Any idea ? The wire ?
