Checksum error on 2017 Toyota Tundra

[AMERICANNERO]

Flashed my truck yesterday and when I hit write it had an abnormally long time to write like 8 minutes when usually it takes like a minute and a half when it wrote to 100% I got a checksum error and now the truck will not start. Anything I can do or is it bricked?

If you connect to the car, can you see the VIN number?

I can not it just tells me controller failure if I try to read it.
