Hello,


I am installing an A3 without LB2 and trying to have some OSD.
I upgraded the IOSD mini to the latest firmware 4.0 and now I am unable to reconect it to IOSD assistant or even downgrade it becaus the assistant always says "firmware mismatch".
I should I do to make it work again and with A3?
Thanks

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

Bit of an update.

Contacted DJI support via E-Mail and sent me a one time download to resolve.

All working OK now.

Tried to use the download again and it has been restricted so can't pass on.

Just contact support and they will be able to help you out.

Hope this helps,

I have had exactly the same issues with my iOSD mini. I have had a protracted discussion with DJI about the problem since January. DJI have asked me to send my mini back so they can have a look. I only found this thread a few days ago so it is rather perplexing to fine that this doesn't appear to be a unique problem and that it has previously been resolved by e-mailing a download which solved the issue and presumably in very quick time At the moment my mini is on its way to Holland. No idea when I will get it back! The only point I noted which hasn't been commented on in this thread is that when I looked at the version of the update it was quoted as being 3.03 (if I remember correctly) even though the assistant quoted version 4xx

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.

Same happens to me and when I contacted support, they gave me some instructions on how to re flash to the previous version using a secret menu. I was sworn to secrecy about the process and may have said too much already. But there is away to go back, re flash and use the iOSD as per before.

An update to my post on the 12th March.

I have received a replacement iOSD mini as the original was deemed to be faulty. The turnaround from sending to receiving a new one was about 18  days.

I installed the new unit to check everything was working and then set up the parameters using the 4.1 assistant, which told me that a firmware upgrade was needed to version 4xx, I delayed upgrading until I was sure that everything was working. Happy that everything was ok I "successfully" upgraded the firmware according to the assistant but guess what; I have exactly the same problem as before.  The assistant tells me the upgrade was successful but there is a firmware mismatch which means that I can't access the set up page to adjust any of the parameters. The mini is working and appears to be providing correct data, but the firmware and set up parameters are frozen.

Having looked through a lot of the post in all of the topics there are quite a few relating to this issue with the iOSD mini so it is not a one off. Perhaps something could be done about this issue!!

Yes something could be done about this. But and i mean BUT that would mean DJI would have to accept responsibility for the widespread issue and either:

1: Post the fix that has been given to so many already over Phone Support ONLY since its a total secret and make each person swear on their lives they won't help or tell others.

2: Just simply fix the issue and post it as an update. Be done, and STOp telling others they MUST call in to fix it.

Well i have a life, Job, family, and the last thing i'm going to do is spend my time on a phone jumping over more language barriers.

Bunt, to the point, and nothing but the truth.

User Pops from fpvlab(.)com suggests doing as follows:
To all that have the DJI iOSD Mini, there is a HUGE problem when using iOSD Assistant V4.01 and firmware upgrade.   When plugging an iOSD Mini into V4.01, the Assistant will state the firmware is upgradable to V4.00 (or V4.01, I don't recall). DO NOT DO IT. The Assistant ID's the Mini as a MKII and the firmware V4 is for MKII ONLY. It will load the MKII firmware and now it will give a "Firmware mismatch" warning. This bricks the iOSD Mini. iOSD Mini latest firmware is V1.06.   DJI site does not indicate this problem exists because they would need to admit they screwed up. They give no downgrade path and you must contact them via e-mail and they will send a one-shot program to fix it.   I found a work around to downgrade back to V1.06   1. Load the older iOSD Assistant 4.0 (luckily I still had the installer file) 2. Start Assistant V4.0 program 3. Connect the iOSD Mini 4. Software will ask if you want to "upgrade" to V1.06. Hit yes to "upgrade" firmware 5. When "upgrade" is done, Re-boot the iOSD Mini 6. All is good now with firmware 1.06 installed   Hope this helps..

Thank you, Pops!
