Had a non-GPS TTGO LoRa32 board (TTGO T3_V1.6 20180606) that was running fine on 1.1.23- just update to 1.2.20 via the Meshtastic Android app and it’s now displaying “Critical Fault #6” and telling me I should post here… so I am! 
I also hit “Report Bug” in the app, but is there another log or anything I should pull from somewhere? I might try flashing the board directly via USB to see if it clears the error, but thought I should report this behavior.
