Describe the bug

When patching an init-boot.img, an error occurs that states "Unknown KMI" and to use --kmi to specify it. How do I do that, and how is the KMI unknown to begin with?

To Reproduce

Open the app
Tap "Not installed, click to install"
Select a boot.img or init_boot.img of a custom rom, such as LineageOS, of a device with the supported kernel

Expected behavior

I expected a successful output of the patched init_boot.img

Your kernel name does not follow the GKI specification, so it is not possible to determine which LKM should be used. You will need to manually execute the command line.

The "android13" label should not be removed.

Ok, so how do I execute the command line for my case?

ksud boot-patch -b <your image> --magiskboot <magiskboot path> --kmi <your kmi>

I'm guessing that line is for a desktop (I have Windows btw) but I don't seem to know where to install the right files to even execute ksud...
