When you have booted into RECOVERY MODE, and you are either trying to make a Nandroid backup or restore, and you get a "Run nandroid-mobile.sh via adb!" error, then try these things: SD Card - it could be too full to write a recovery. Try deleting some things and try again. "Nandroid folder" inside your SD card - If you have renamed some of your backups, then this could also be an issue. Change the names back to what they were and try again. If anyone else has other experiences please feel free to add them here so others will have something to look at when in need.
