I "updated" the firmware on the IOSD Mini to version 4 and now it is mis-matched on the firmware and can not make or save changes.  Does anyone know how to downgrade the firmware?

You can only reapply firmware for the iOSD Mini, it cannot be downgraded. Just to clarify, what flight controller are you using?

Got the same here and just can't seem to get by it.

Has anyone had any luck with this at all?

Upgraded to 4.0 and just get Firmware mis-match and cannot get to the main screen. Now when i check for updates, it tells me there are none. This is on a NAZA M V2 on latest firmware.

Any help would be awesome!

Regards,

Hal

dear,
I have the some problem

I have the same exact issue. Opened the 4.1 iosd mini app to adjust settings; said a FW upgrade was available to version 4.01 from 1.06. Upgraded, said successful, restarted device and now i can't get into the Menu to adjust any settings, only says Firmware Mismatch.

Iv also got the same problem

Any progress on this one?
In the iOSD assistant I see firmware version in my iOSD mini 4.00 and latest version 4.0
so I guess there is somewhere a mismatch ... looks like a 0 is missing or to much.
Would be nice if someone fro, DJI could jump in.

Same issue here.  Any updates?

Same issue for me, I was running v.1.06 before I connected it to the computer and performed the recommended firmware update. I haven't tried the function of the IOSD mini yet. Using it with Naza M V2. Though I can't make any changes in the DJI iOSD Assistant (v4.1) anymore.

DJI, I know this is a discontinued product. But anyone trying to update to the latest version of the IOSD mini will end up here. So please make a comment with some kind of statement.

Regards,
Fredrik.

Update!

The problem can be resolved by either contacting DJIs support or by using iOSD Assistant V4.0. The software is still downloadable via DJI at this location:

Hit "Upgrade" do perform the downgrade the firmware from 4.00 to 1.6.

Pefect thanks for the information - rolled back the firmware on mine perfectly to v1.06 and allowed changing the settings again.
