"I managed to program thit chip using just FT2232H JTAG and some python code to take binary and send it to the controller. "
Would you mind sharing that python code please?

I found something, even though it's most likely an initial version. It connects through telnet to a running OpenOCD instance and sends direct reads and writes and talks to the controller... I've given you access in private but if it works fine I'll happily disclose it for the public.
You'll need the correct openocd script with the fix I mentioned before.
The way to go would be to write the 'correct' driver for OpenOCD. May be that's the time....

Hello! I would also like to get this code in Python if possible! I'm currently trying to fix my laptop, I replaced the EC from another model's laptop, and the computer is not working.
For anyone lurking, here it is. Once again I observe yearly resurgence in interest in this topic so making a mental note to add a proper driver to OpenOCD someday

Pretty cool! Glad that you figured it out.
My thinkpad still has UUID and machine ID emptied after the reflash, so maybe I'll return to that project some day...
Having OpenOCD as an alternative to closed-source "repair" programmers would definitely benefit some folks out there...
