I believe you need an pandora battery to downgrade your OFW.

and a magic memory stick...this might help you out http://forums.afterdawn.com/thread_view.cfm/610313 tells you how to make a magic ms and pandora battery without cfw

Just follow the link that amaric gave you.. I also had the same situation as you before. Making the Magic Memory Stick is easy with the program provided your only trouble is where to get a pandora battery... You can either hardmod it or try to look for a program that would convert your slim battery to a pandora battery and back to a regular battery pack.

Good luck!

you can also hardmodd a slim battery...it is posssible i did it...and buy a second one though i wouldnt recomend it, youd be better off buying a datel tool battery it works just the same as a pandora one just already modded or the new datel battery converter it changes your battery between pandora and normal wit the click of a button(so it says)
