ISC-027BW Grill reading Help

I can’t get this to change. Probe plugged in not plugged in it reads 300 degrees constantly. I’ve tried a reset and it prompts me to upgrade firmware from v1.0.0 to v1.0.6 it appears to complete then the temp reading drops to 0 then immediately goes back
To 300. I reset again and again it says update firmware! It’s like Groundhog Day! Food probes temps work perfectly. How can I fix this?
