Looking at the mod instructions, my mind immediately goes to the part about cutting traces. You probably already have, but the first place I would look is making sure only the traces that are supposed to be cut have been cut, and that the cut traces are completely severed. Mutlimeter continuity check on the cut lines to make sure there is no continuity, and multimeter check on any nearby lines to make sure they still have continuity.
