So i got a PW2 this week after enjoying my K4 for several years. I had all my collections set up using Calibre. I realised straight away i can't do collections like that anymore and need something like LibrarianSync.

So i need to jail break.
The PW2 started at 5.8.1 (i think it did an update between me getting hold of it and realising i needed to JB).
I successfuly downgraded and JB it, got the mkk folder, and installed KUAL.
At the 5.4.3.2 FW i can see KUAL on the home screen (but it doesn't run, which is correct for non-Japanese models right?)
When i update back to 5.8.1 i can no longer see a KUAL shortcut.

Am i misunderstanding what capabilities i should have?

All i really want is LibrarianSync

Help and/or direction much appreciated
