If your backup already has a9lh it won't remove it.
Yeah but if he followed the guide properly doing the a9lh install, he should have a sysnand original like i mentioned before. Restoring that without keeping a9lh will revert to a stock 9.x. Format the SD afterwards and that's it.
I don't get why people have mods, yet don't have backups to rely on.
