Clone Android device including the content of SD card I have to clone about 65 Android devices (Samsung Galaxy Tab 10.1N). I would do it with a backup in CyanogenMod, but the problem with the Cyanogen Backup is, it does not back up the SD card.
Any other methods to completely clone an Android device? (Homescreen settings, installed apps, data on SD card, etc.)
Make a nandroid backup from recovery. 
Make sure that the backup is located on the sdcard. 
Mount the sdcard on a computer and copy it's contents to a folder on a pc.
Copy the entire contents of the folder you made above to the target device. 
Root the device than install a custom recovery if you didn't do this already. 
In recovery restore the nandroid backup. 
Reboot the device. Now everything should be exactly the same as on the original. 


Repeat steps 4-7 for every device. 


If there're lots of small files that need to be transferred, another possibility is zip them up copy to the phone and than unzip it using 

adb shell unzip path/to/file.zip


Once the command is launched you can disconnect the device the process will continue as long as there're no conflicting files or folders.
