I've only ever used Magisk on my phones, but now I have been looking to Kernel Su. I'm currently on crDroid. I tried using kernel su next manager to patch my init_boot. I chose the matching kernel 6.1 android 14 in the manager my device went into bootloop. If anyone knows how to install it with LKM mode would be helpful. I guess it is supported as the manager doesn't say unsupported.
