    Have never been able to get into Mask ROM mode.. What am I doing wrong?

    I have 4 J22's here that are bricked from having incompatible ROM's put on them. Have tried many times to do the 7-8 or 8-9 pin bridging on the correct chip.

    I did see someone talk about doing USB 1.1 and that fixing it? What is that?
