Well, I tried to enable a theme (FDB), and didn't realize that the fdb folder MUST be in ~/MyDocs , not in any other folder. So, when I ran the script, there were lots of cp errors, which I couldn't read because the device rebooted too fast, neither I could press ctrl-c... So now I'm stuck on the boot animation, I guess because it can't find the boot video. I want to restore the default theme with the 'default.sh' script via SSH, and that's the problem...
