I can't relock my bootloader. Haven't rooted or anything. I unlocked it, couldnt flash the kernel for root so gave up on it and wanted to relock my bootloader. Getting these errors:

c:\adb>fastboot flashing lock_critical
FAILED (Write to device failed (No such file or directory))
fastboot: error: Command failed

Any ideas?

Are you sure the kernel didn't flash at all?

I'd recommend flashing a factory image and then trying to lock it just in case something went wrong.

If it still doesn't work is your device showing on CMD using "fastboot devices"?

I'm getting the error device already locked even though my bootloader clearly states that the bootloader is in unlocked. I just flashed the factory image for the phone and still same error. Any ideas?

hello i was able to get it to show up in fastboot devices but i am unable to relock...when i try to get it to relock it goes and says waiting for device even though its in fast boot mode.
