Samsung A21s software fastboot is disabled



  • I have a Samsung Galaxy A21s phone that I am trying to install Android 12 on. I have unlocked the bootloader, I go into the recovery mode and I select bootloader, however when I get there, it is just some red text saying "Entering fastboot mode..." and then it gets stuck there.

    Does anyone know why this is happening, and if there is any way to fix it without carting it off to Samsung?



  • Samsung devices only have a placeholder Fastboot mode. It doesn't actually serve any purpose. Please use Download Mode instead.
