| Method | How it works | Does it disable verification? | |--------|--------------|-------------------------------| | | Some Magisk versions try to keep dm-verity enabled while modifying boot only | No (partial) | | KernelSU | Kernel-level root that doesn't modify system partition | No | | AVB custom keys | Replace OEM keys with your own, sign all partitions | No (but requires re-signing) | | GSI with AVB test keys | Use pre-signed GSIs that match generic test keys | No (but risky) |
