[Development] How to unlock and relock Android bootloader with fastboot
(29-09-2021, 09:56 AM)Trunks614 Nothing comes up when I run command "fastboot devices". When I run command "adb reboot-bootloader" my phone simply switches off. I've also tried manually booting into bootloader through recovery mode, but the device also switches off. Please what could be wrong?

Then, he says we must flash the official firmware.
question is, flashing stock rom does not re-locks bootloader?

unless the person gave a specific process to follow, e.g on a mediatek device, erasing or overwriting seccfg partition relock the bootloader
so if you flash firmware without formatting or overwriting seccfg then bootloader will remain unlocked
