Flashing stopped working after 3 or 4 successes, hangs/aborts at "Upgrading to programming session..." #139

Was able to unlock and successfully flash the ECU 3 or 4 times, but now when I try to flash it with either a tune or stock file, it gets to "Upgrading to programming session..." and aborts. If I try to relock, I get the same error. If I try to unlock again, I get an error unpacking the file. "Get ECU Info" still works. I suspect I did something I shouldn't have and bricked the ECU, but I want to know if there is any way to recover.

Hi; I can’t see this Google Drive link. Usually this means you flashed a file without a matching power class, but it could have a less fatal cause too.

My apologies, permissions have been updated.

It was a Hail Mary pass at an attempt to get a CTUA block running with a CXCA ECM and sensors, so it wouldn't surprise me if that is the case.

Thank you for your time.
