GM MDI2 - MTS6531 VCI to Bosch VCI

Hi pals! do you know there is some possiblity to change firmware of this MDI2 from GM to Bosch VCI MTS6531. I think there is the same hardware and im seeing that can be more usefull for me if it's bosch firmware than gm.

Did you succeed to change firmware?

Did you succeed to change firmware?

Not at all. didn't find solution for this. I find somthing about changing serial number but not sure. any suggestions?

Please attach photos of the pcb. I have successfully converted MTS6520 to MTS6520-Saic, as that variant was the only one for wich I was able to find a driver.

I know this is an old thread, but hopefully someone knows how to do this? Or does anybody know if there are PINS on the board for a JTAG or serial console?
