A complete factory reset (not just deregister) will take you back to the firmware version that came with the device out of the box. If it's earlier than 1.2.1, you can upgrade.I am on 1.2.2 now is it possible for me to downgrade to 1.2.1 ? I really need a rom like this but i don't know how to do it :/
However, I doubt you can get the 1337 ROM to work properly for you. Start reading here.
