Opening CMD as an admin

Open CMD as an administrator, then run the below command, replacing path\to\platform-tools with the actual path to the platform-tools folder, for example C:\platform-tools.

Do not close this window. You will need to use it throughout this entire guide.

cd path\to\platform-tools

Boot modified TWRP recovery

Replace path\to\moddedtwrp.img with the actual path of the image

fastboot boot path\to\moddedtwrp.img

Back up your boot image

This will back up your boot image in the current directory (for example C:\platform-tools).

adb pull /dev/block/by-name/boot_a boot.img

Setting up required files

• Download magiskboot.exe and move it into the platform-tools folder.
• Download DualBootKernelPatcher.zip and extract the DualBootKernelPatcher folder into the platform-tools folder.
• Download DEVICENAME.fd for your device and move it into the platform-tools folder.

Unpacking your boot image

Make sure boot.img is in the platform-tools folder.

./magiskboot unpack boot.img

Patching your boot image

Replace DEVICENAME.fd in the below command with your actual devicename (guacamole.fd or hotdog.fd)

./DualBootKernelPatcher\bin\Windows\DualBootKernelPatcher-x86_64.exe ./kernel ./DEVICENAME.fd ./output ./DualBootKernelPatcher\Config\DualBoot.Sm8150.cfg ./DualBootKernelPatcher\ShellCode\ShellCode.Hotdog.bin

Renaming the kernel file

• Delete or rename the kernel file in the platform-tools folder, then rename the output file to kernel

This will repack your patched boot image into a new file called new_boot.img

./magiskboot repack boot.img

Reboot to fastboot

adb reboot bootloader

Flashing the patched boot image

Replace path\to\new_boot.img with the actual path of the image
