I'm trying to unlock the bootloader of my tablet for hours now.. There's no solution out there that worked for me. I've already tried:
- fastboot oem unlock (the tablet responses with a question screen where I can select "yes, unlock bootloader" and "no, don't unlock bootloader", but when I select yes it responses with an error "Unlock failed - Err:0x7000")
- fastboot oem bootloader unlock (this command stucks at "...")
I also tried to flash custom recovery so I could get around this but now I'm stuck in a bootloop.. I have a backup of the stock recovery, but I can't flash it either..
fastboot flash recovery recovery_stock.img responses with:
sending 'recovery' (10240 KB)... OKAY [ 0.417s] writing 'recovery'... FAILED (remote: Security deny - Err:0x2017 ) finished. total time: 0.430s
I know that
Security deny - Err:0x2017 is because of unlocked bootloader...
