Before update I had installed JB 0.5.1, Screensaverhack 0.24N, and german language (from DiBa) 0.92M. Then my fault: I have resetted it to factory defaults without de-installing anything, and updated to 3.4. The update works fine.
Afterwards there was no JB (could not install other hacks) and the re-install of JB dosn't work.
Sorry for my ignorance, I am a totally beginner ....
