DUMLdore v2.12
Downgrading from V1.4.0100:

Choose new jcase anti-rollback method
Wait for it to defeat it (may take up to a couple of minutes)
Normal start flashing dialog will show
Upgrade will begin
Close DUMLdore
Check with Assistant2

After the upgrade Assistant2 will probably show the firmware as:
1.4.0100-

It has downgraded but some modules were skipped
Close Assistant2
Start DUMLdore and flash as per usual
Say NO to new rollback method (we dont need to do that now we can just do it the old way)
Normal start flashing dialog will show
Upgrade will begin
Close DUMLdore
Check with Assistant2 (it will be a much faster flash than before)
Upgrade will complete and show the correct firmware

@MiniChopper4Me What mavic do you have? Artic, Platinum or just plain Mavic Pro?

I have an old Pro, from October of 2016. I just had to do the IP address thing to be able to connect to the ftp server.

Now the process completed, but Assistant shows ver 1.4.0100-

I'm trying to do DUMLdore again as suggested, but keep getting stuck on stage2.bin with no more progress (tried twice already). Seems these old Mavics are finicky.

 

[MiniChopper4Me]

Nevermind, you just skip the downgrade defeat method the second time by clicking "no". Its downgrading again now.

I actually updated mine from 400 to 700 but I want the quickshots which is on V01.03.1000.

I have a Mavic Pro sept2017 build on 4.100 came with 4.000 so not sure if it has a internal sc card . So what are my best options 700 or need to stay at least on 4.000 or higher with some mods removed like 306 &305
Want to be able to modify all parameters like my spark with assistant

Finally i can downgrade to .700 [emoji16][emoji16]

Looks like you can't find some of the file.
Try downloading the zip again (not just the .exe) and make sure that you extract ALL files.

This is a system issue
Try this connection test:
Timeout while trying to backup Mavic Pro v01.03.1000 firmware · Issue #9 · jezzab/DUMLdore · GitHub

You can also "de-install" and and "re-install" Assistant to make sure all driver are properly installed.

Well i took the plunge

But the Dumbldore tool just sat as Stage1.bin and that's it. I left it for 5 minutes and no change

So i started again and the only thing I didn't do the first time was to open the assistant and close it before starting Dumbldore.

The tool reported that the roll back was defeated and it copied the file to the quad

I closed out Dumbldore and opened the assistant and it showed no sign of upgrading.

Quad got restarted and again no sign of upgrading

So I started again and once again Dumbldore finished stage1.bin and reported (flashed up real quick) that anti roll back was defeated and then started stage2.bin and nothing it sat there for another 5 minutes so I turned off the quad and gave up.

The app shows that the quad is upgrading but it isn't according to the assistant software



I hit refresh in the assistant and let it reflash the latest FW.

Only thing i cant do now is get the IOS app to connect, the Android app works fine

update, i had to remove/reinstall the app on the IOS for some reason

what about the restore factory defaults option will that rollback to original firmware?
