I was trying to get a bit familiar with fastboot commands.
I have tried to use oem lock command, this locked my 410C board.
$ sudo fastboot oem lock
Then I tried to unlock bootloader but failed.
$ sudo fastboot oem unlock
…
FAILED (remote: oem unlock is not allowed)
finished. total time: 0.003s
$ sudo fastboot oem device-info
…
(bootloader) Device tampered: false
(bootloader) Device unlocked: false
(bootloader) Charger screen enabled: false
(bootloader) Display panel:
OKAY [ 0.007s]
finished. total time: 0.007s
Since bootloader is locked, now I can not flash images to my board.
$ sudo fastboot boot boot.img
downloading ‘boot.img’…
OKAY [ 0.768s]
booting…
FAILED (remote: unlock device to use this command)
finished. total time: 0.771s
I have tried to recover the device by re-flashing the SD Card image with no luck.
Can anyone help?
Thanks
