I'm now having a Samsung Galaxy Superior (GT-I9260) running on cm12.1 downloaded from the cm website. I want to flash it to kali linux now, and it tells me to unlock the bootloader first. After doing some research, I found out that people suggest some commands like
adb reboot bootloader and
fastboot oem unlock. But I just cant boot into the bootloader, even if I'm booting it from the recovery using the option
reboot bootloader. My problem is, is that my bootloader has been unlocked, or I need some other ways to make it work?
Note: I'm currently using a linux computer.
