Development BKLYN Kernel for SM-G998B (Samsung Galaxy S21 Ultra)

Search This thread
mate, I had bootloops initially (God knows why), while installing kernel, solved it by sideloading Magisk-558710bb-alpha-2(23016) and installing it after flashing the kernel as per instruction of the creator.
Cheers for the update Champ....

Truth be known the Kernal that comes with the rom I'm using is great... I don't tweak CPU etc, but I did find this one gave me better battery.

I just couldn't be f88ked stuffing around with it to be honest.

    This tutorial assumes you understand how to use adb and fastboot.

    Your device’s bootloader has to be unlocked.

    IMPORTANT NOTE: It seems some users need to flash a vbmeta image file provided by Google in order to boot and user the Custom Kernel. If you find yourself in a situation were you are not able to boot, please flash the attached vbmeta img along with the Kernel and if still bootlooping share the last_kmsg to determine what's driving the issue.
