Hi, I f***ed up my SGS by installing a theme.
I created a backup of the files, overwritten by the theme.
The problem is I can not start my SGS anymore.
So I started into Recovery mode and conntected to the SGS via ADB Shell.
everything is working there but when I say su I got the error: permission denied.
And yes my phone is rooted and I also installed apps which needed root permissions.
How do I get root permissions in the adb shell during recovery mode?
