There are two methods listed below, the first one requires root, the second one does not. Use whichever method suits you the most, as they both do the same.
- Download and install the WOA Helper app, then open it and grant it root access.
- Open WOA Toolbox, then press the DUALBOOT KERNEL PATCHER button.
- Wait for it to finish, then reboot your device.
- Close the magnetic case and reboot (or turn on) your device.
- Open the magnetic case and reboot (or turn on) your device.
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
While in fastboot mode, replace
path\to\recovery.img
with the actual path of the recovery image
fastboot boot path\to\recovery.img
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
- 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 nabu.fd move it into the
platform-tools
folder.
Make sure boot.img is in the
platform-tools
folder.
./magiskboot unpack boot.img
./DualBootKernelPatcher\bin\Windows\DualBootKernelPatcher-x86_64.exe ./kernel ./nabu.fd ./output ./DualBootKernelPatcher\Config\DualBoot.Sm8150.cfg ./DualBootKernelPatcher\ShellCode\ShellCode.Nabu.bin
- Delete or rename the kernel file in the
platform-tools
folder, then rename the output file tokernel
This will repack your patched boot image into a new file called new_boot.img
./magiskboot repack boot.img
adb reboot bootloader
Replace
path\to\new_boot.img
with the actual path of the image
fastboot flash boot_a path\to\new_boot.img
fastboot flash boot_b path\to\new_boot.img
fastboot reboot
- Close the magnetic case and reboot (or turn on) your device.
- Open the magnetic case and reboot (or turn on) your device.
