Want to change CSC on your Samsung Galaxy S III and Samsung Galaxy Note II? You still can use the old method ~ type *#272*Device IMEI# at Phone dial pad on older Samsung Galaxy S3 firmware. However, latest firmware (like XXELLA) disabled this shortcut. And this method totally won’t work on Samsung Galaxy Note 2. How to change CSC then? No worry, CSC Changer application comes to rescue. Thanks to XDA Developer, bassie1995. However, root access is required.
Note – Changing CSC will factory reset your phone. Everything will be deleted. Do backup before perform this task.
