Launched MavicPro in the air to hover but it started to fly away erratically not listening to controller input. Tried to land it and it crashed. Airdata link below and DJI Go4 files attached. Someone who knows how to decipher this, please tell me what happened, thank you very much in advance.

I'm no expert, but I found this below. Don't know what FORBIN error is, nothing came up on my GO 4 screen, and clueless what could have caused an ESC error, with plenty of battery.

It's hard to tell what happened from the data.
There were non-specified error messages all over the data right from the start.
The drone never recorded a home point and shouldn't have been launched.

Odd, the data shows an "H", from where it was launched. Also, I've flown without GPS signal in canyons and mountains before, manually, and it wasn't an issue. I bet it's the "ESC error / not enough force" that caused the crash. Wonder what happened. Maybe it overheated?

Looking into the code for "FORBIN" I found this:

local REC_OSD_GENERAL_GPS_STATE_ENUM = {
[0]="ALREADY",
[1]="FORBIN",
[2]="GPSNUM_NONENOUGH",
[3]="GPS_HDOP_LARGE",
[4]="GPS_POSITION_NONMATCH",
[5]="SPEED_ERROR_LARGE",
[6]="YAW_ERROR_LARGE",
[7]="COMPASS_ERROR_LARGE",
[8]="UNKNOWN",
}

It is part of the GPS status process, I'm not sure, but it may mean forbidden as in takeoff is forbidden but who knows without pouring through a lot more code, so it remains a mystery....

Cheers!
