MP DAT Files Problem

[whatmeworry]

Have a prob w/ the MP.
So I...
Imported 7 DAT files from DJI Assistant 2 from the MP.
Only 3 files show up in my folder.
Used DJI Extract on the files and nothing shows up in another folder.
Ive done this before successfully in the past. They will show up as FLYxxx.dat

Whats going on ?

 

[whatmeworry]

I deleted the dat files and folders from the MP1 memory.
Did 2 takeoff attempts. There now 2 files showing.
Dwnloaded and extracted. Still no flyxxx.dat

Have you tried just processing those files through DatCon?

Needs to be extracted first. Extraction shows no flyxx.dat.

The MP1 main problem is the rear end lifts off and flips over. Doesnt lift level.
Trying to get motor data.

Going revert back one firmware version. Last nite it took over 1 hr w/out success.

Without seeing the file in question I can't help. Have you considered just using the mobile device DAT file? That will include all the data that you need to diagnose that problem.

Android only shows xxx.txt files in flight record folder.

Firmware downgrade unsuccessful 4x. Disconnects at 24% updating.

Right - this is far too little information for me to be able to help you. Good luck fixing it.

I have pre-crash dats. DJI Assistant dat -130mb. Extracted cvs-19mb and flyxxdat- 178mb.
What are guidelines for posting attachments ?

If it wasn't props fitted wrong, do you know what it was ?

 

[whatmeworry]

It had a broke left rear arm. After repair, problem was the wires were switched on the main board. doh !

Re-calibrated the IMU. Flies like new.

The person who crashed it, according to geo location dat, took off on a sidewalk, next to parking lot and a building.
Possible mag interference ? Or possible someone forced the LR arm and cracked before takeoff. or IMU was off. Not sure.
Altitude was about 2.3m.
Heres an overlay... Red is LF motor, blue is LR motor.

You're likely to get more help if you could provide more info. Two suggestions
1) Use the Copy To Clipboard feature

and then paste into a post via a Ctrl-V. That way the legends are also copied




2) Provide the .DAT using something like Dropbox or GoogleDrive.
