I previously had stage 2+ OFT tune on my 2019 brz. Today I tried to flash to the original file. I've switched the tune using the OFT a decent number of times and all things seemed normal until it was about to finish writing. I received an error on the tablet:

An error occurred while writing the ECU. Check cable connections, ignition switch position, then try again. Error code: 10010

I kept the tablet and cable completely still while it was writing.
After this I checked cable connection; all seemed good there. Assumed maybe it was a fluke and tried flash back to the original again. This time it didn't even begin the write operation. I was receiving the 10010 error before any writing happened. At this point I tried seeing if the OFT could
read any data and got nothing. Can't see live diagnostic info, can't get ECU info, nothing. After this I unplugged OFT and tried to start the car. No crank, car won't start.
Before flashing the car had been running for ~30 min so I'm thinking it was unlikely a problem w the battery being low. I also disconnected the battery for about an hour and tried to start again, didn't work. When ignition is on I see a 'engine coolant high temperature' warning? Honestly no idea what to do from here. I'm thinking I'm screwed but I figured I'd post here to see if anyone have ideas before I start spending money to fix this issue.
