After unbricking, all the sensors need to calibrated. Does Modalai keep a factory cal file from initial set up and flight? I think I saw a post somewhere in the forum, but I cant find it.

@McMason Yes, if you provide the serial number of your drone, which is on a white sticker in the form MXXXXXXXXXX, we can provide you with your camera calibration files. The rest of the calibrations (imu, gyro, etc.) can be done easily through QGC.

@tom, have you had any issue with calibration or operation over WiFi? I know there is a warning about it through QGC

@McMason That is how we usually calibrate our sensors, you should have no issue doing so. I will send your camera calibration files to the email you have registered with the forum.
