What does the MRPI log show?
If reinstall KUAL-coplate via MRPI doesn't work, all I can think of is this:
- factory reset (deletes hotfix and user data but *should* leave jailbreak alone)
- reinstall hotfix (link)
- MRPI (from NiLuJe snapshots)
- KUAL coplate (link)
Unfortunately, factory reset runs the risk of losing the JB.
