Bootloader unlock
First method
This method works on most sc9863a devices.
- Download required files
- Open Developer options and toggle Bootloader unlock option on
- Move to fastboot mode
- Get identifier token with
fastboot oem get_identifier_token
- Run
./signidentifier_unlockbootloader.sh paste_token_hre rsa4096_vbmeta.pem signature.bin - Run
fastboot flashing unlock signature.bin
Second method
Some manufacturers sign bootloaders with their own keys (e.g. Itel). In this case, bootloader exploit may help with unlocking, see https://github.com/TomKing062/CVE-2022-38694_unlock_bootloader for more information.
