No success. Uninstalled jailbreak twice, restarted, uninstalled launcher again, same result. Error 006
Will have to go the way back to jailbreak and reinstall my stuff on 5.0.4 again.
I had a similar problem on my K3 from 3.2.1 to 3.3, what solved it there was, to overwrite a pem.key in the system. Anyone a clue, what the "original" pem.key should be?
