@s1guza hey! Do you possibly know how I could extract the root filesystem key of a firmware below 10.x with checkm8? There’s no information on it and it seems to be impossible

AFAIK it's embedded in some daemon on the ramdisk(s). Don't know details though, never had to deal with that myself. cc

get the ramdisk iv+key, then decrypt+extract the ramdisk from its container (img4). then, you need to feed that ramdisk along with rootfs and platform name to genpass[1] to get the passphrase. extract the rootfs with vfdecrypt, using said passphrase. [1]https://github.com/xerub/genpass
