Hello
I wanted to install Syberia A12 from stock A11 and I got stuck somewhere in the process.
So I'm stuck with the internal storage on the phone (not backed up) that is inaccessible since it's encrypted and the rest of the partitions backed up on the pc using adb backup (a single .ab file).
In theory I should restore the partitions to the phone and I should be able to access everything and boot as it was before, right? However now I have the syberia ROM installed and I'm not rooted anymore (and won't boot).
Can I restore /system like this?

What I care about is access the internal storage, what can I do?

I tried restoring the entire .ab file, however it gets stuck at "restoring efs2" and I should only try to restore /data and /system but I can't select specific partitions being a adb backup with twrp.
All tools I tried to extract the content fails.
