I had cssu-thumb installed in my N900 , and when I updated the catalogs in app-manager I saw the new update to T-Maemo 6 .. I just updated to it and everything went ok and after rebooting I could see the version 1Tmaemo6 installed in my device , but with no thumb ... did that returned me to cssu-testing and just remove the thumb , or thumb was crashed ?? is there any effect on my device ?? can i roll back to thumb if the new update will be dangerous ??
