I have installed several ICS leaked ROMs on my SGS2. In the last ones there has been a problem with the annoying Software update notification that wont go away because registering fails every time. I have now flashed the 'official' final release found at XDA ([ROM+Guide]Official i9100 Firmwares K/G/H/I/J/K1/2/5/KL1/2/3/LA2,4/LB2,LPE/Q Download - xda-developers) (XXLPQ MultiCSC). This problem persists, it is not possible to accept the terms of the software update agreement, and the notification is still there 
So I tried to install a gingerbread rom (XWKI8) from the same thread so I could update to the newest firmware OTA instead. But after installing it keeps crashing during the setup wizard
Now it seems I cant go back to GB and I cant get ICS to work properly.. Can someone please give me a hint on this?
