How to rollback Mavic firmware

[Racin8de]

Just the RC on its own, no mavic
Want to see if its the computer or mavic

Connect RC to PC using USB, power up RC, wait 2 minutes for it to boot then try FTP / DUMLdore

Ok , I will give this a try.

Once it updated to the normal stock 1.4.000 via the app, I was then able to rollback to .700. No issues there and functioned like it should under .700. I then proceeded to upgrade to a modded 1.4.000 (minus 305, 306, and 905), without a problem. It runs the modded 1.4.000 like it was .700, and yet I now have the new Quickshot features and compatibility of other apps, like with stock 1.4.000 firmware.

Does this method (3.700 -> modded 4.000) work with DroneZBreak on a Mac? Anyone tried? I've downgraded to .700 on a Mac, not with DUMLdore on Windows; now that people are having issues with the latter, I'm wondering if doing this on a Mac will be a more smooth sailing.

Does anybody have a description of each of the modules in the firmware? A couple posts here mentioned removing the 905 module in addition to the 305 and 306 modules, so I'm wondering how do you know what each one does?

Does this method (3.700 -> modded 4.000) work with DroneZBreak on a Mac? Anyone tried? I've downgraded to .700 on a Mac, not with DUMLdore on Windows; now that people are having issues with the latter, I'm wondering if doing this on a Mac will be a more smooth sailing.

It shouldn't make a difference. All either of those programs are doing is uploading the .bin file to the Mavic itself. Once there, the programs can/should be shut off. The Mavic does the rest automatically.

I suspect that all the problems people are mentioning with the error messages are related to the ftp connection being made via the COM port. This is a communication issue, nothing more. Likely it is a TCP/IP issue or a firewall causing the lack of communication. I'm no networking expert, so working out the COM port communication to the Mavic is out of my wheelhouse.

 

[JustViewerFun]

Okay, next question...
Do backups via DumLore also backup my current settings like yaw EXP, etc.? So, if I restore the backed up firmware version, later I'll get my settings back?

Not at all. You have to write down/screenshot those and set them back, even after most official updates.

Ahh, bummer! I have them written down already, but I was hoping this would be a way around that. Oh, well. Thanks for answering, Kilrah

This exactly the problem I'm having.I have tried everything,even HaloweenHampster helped me yesterday trying a few different methods but none worked.I also tried to setup another connection on my router instead of using wifi and nothing. This is crazy, this is the worst problem I've ever had trying to figure out a PC issue. I do appreciate the help Gents,thanks !

 

[vtcats]

Quick question/thoughts
I've updated from 3.700 to modded 4.000 both the Mavic and RC and now have unmodded current iOS app.
After turning on I got my first compass calib since I did it when it was purchased this past spring.
It was next to all my electronics/router etc, so I turned off and moved outside. This time no warning.
Any thoughts as to if you would go ahead and calibrate it or not?
Too dark now to fly but will tomorrow to test everything.
Also, Lisadoc, let me know with my parameter question via PM.
Thanks

Probably no need to but it won't kill you if you did.

Also, Lisadoc, let me know with my parameter question via PM.

I already did.

I figured it out.

Control Panel\Network and Internet\Network Connections

Find your Local Area Connection RNDIS adapter.

Right click / properties

Double click Internet Protocol Version 4

Set the ip address to 192.168.42.3
Subnet 255.255.255.0
Gateway left blank
DNS servers left alone as well.

Close DUMLDORE. Relaunch. Problem is fixed.

 

[xtravbx]

Yes

HaloweenHampster- The DUMLdore picks up aircraft it says COMM 3. DUMLdore won't let me backup files, I get the FTP error code with that IP address.I have tried reinstalling, using another laptop with Windows 8.1 which DJI Assisant doesn't even detect aircraft.Windows 10 does detect aircraft..Any help would certainly be appreciated ..- thanks

Check my post at the end of this thread w/ your answer.

 

[Haloweenhamster]

Sorry the developer of DUMLdore posted the answer 23rd Oct, I missed it


For win 10
Settings > network & internet > Ethernet > change adapter options > Ethernet * > properties > internet protocol version 4

* which ever one has NDIS in the description

Hi, is still possible rollback mavic from 01.04.0000 to 0700?? I'm not sure but I had read someone said there are problems now to do it, something about SD Card errors.

There's no issue rolling it back from 1.4.000
