How to rollback Mavic firmware

[brett8883]

1. Yes I have tried. When I connect RC with Phone and go to pairing. I get the message "Difine Frequency" and only give me the option yes or cancel. YES and wont do nothing.

2. Yes, aircraft in RC mode.

3. Yes. I downloaded each firmware for AC and RC.

4. Assistant V1.1.2View attachment 84306View attachment 84307View attachment 84308View attachment 84309

Ok you need Assistant 1.2.5 for Windows to update the firmware on the Mavic. Assistant 1.1.2 is only for modifying parameters.

Use the newer version of Assistant to upgrade the firmware on the RC.

If that doesn’t work use this version of dumldore instead DUMLdore v3.12 which has support for flashing firmware to a device with “unknown” firmware.

This is the remote right? Try updating the remote to the latest version instead.

Dumldore is linked above. Just click on the text DUMLdore v3.12 above and it will automatically download

"Unsble to connect the device to FTP server connection message"

This explains how to do it. How to rollback Mavic firmware

I am having an issue with DUMLdore flashing the firmware, completing successfully, but when I turn the drone on it is still on the same firmware.

I'm trying to go from 1.03.1000 to 1.03.0700 - any help would be appreciated. I also tried using NLD and all flashing fails. Drone still works fine and DJI Assistant can successfully re-flast to 1.03.1000.

Thanks!

It was bought a long time ago and I'm pretty sure it has the SD card, but there's not way to check without ripping it apart. Production date is 2017-09

You may have to go down gradually like .800 etc flash it 2x make sure to enable adb every time esp. when you reboot

Yea, I tried 1.03.0900 with no luck - doesn't seem to take anything I throw at it.

I found that all versions of DUMLdore >= 3.00 failed in this upgrade path. Upgrade gets to 15% then skips to 100% and exits. I only succeeded when I used DUMLdore version 2.14.
