You don't need a NAND backup to use the installer. You can install different forks normally.So I was curious, is there a simple way to update the a9lh fork? or do we have to use the installer combined with our original nand backup again if we want to change it? I'm also assuming you cant just backup your 10.7 sysnand and use that with the installer if you already have a9lh installed? Again just curious, and doesnt look like anyone has asked this yet so figured I may as well.
