My guess is your "gizmo" is no good. I never heard of such a device that does such a thing. I hope you didn't pay much for it.
All you should need to mod a phatty is Pandora Battery Creator on your modded slim, the battery from the phatty in your slim and a good tutorial. (check our tutorial section)
Take your time and read carefully.
Good luck.
Oh and update the firmware on your slim to at least 3.90.
