bricked 2010 TCM

I tried tuning a 2010 duramax and once I read out the file I had no definition, so I emaild and I would have to use the newer 2.24 software which cant do delete so theres no point. I then tried flashing another 2010 OS that will work with 2.23 it flashed but now tcm was all messed and cant get it to work correct. so I gave up and tried to return to the orig file that I had saved. all that happens is it goes into tcm recoverey finishes but doesent work. I cant communicate with the tcm, even took to GM and a tech 2 cannot communicate with it.

getting a weird c101 code,

basically im about to buy a new tcm and try flashing with efi live or h and s

any ideas? I know the 2010 is the A50 but we have the ability to flash that I thought?

I also have a bench harness so I could take out the ecu to reprogramm but not the TCM


any ideas would be greatly appreciated
