I spent the last couple hours confirming I have the info I need to be able to reprogram the pic firmware. Whether it works in the particular case / problem you have is a different issue. It will take a little more work than I had hoped (my code needs more refactoring as the S9 and T9's talk to the pic in a different way). I don't know that I will get it done today, but I will continue to work on it.
On the plus side if it works. The bmminer I made allows you to overclock it haha. It's the same firmware as the 8.8v for the s9 just for the T9 firmware hopefully darval will be able to help you out!
