I have 2.77, 2.80, 2.85 and 2.86 as an ISO to burn a CD. I also have 2.86 to put on a USB stick.

Hi im searching for the 2.85 Version du Update my currently FW 2.21. Ive read that Updating from lower Version directly to 2.86 can cause Problems.

Best Regards

According to the attached charts updating from 2.21 to any later version will mean losing your configuration settings. This will need either paying a dealer so that they can download the configuration files from the Stellantis servers or using Diagbox to change individual settings. You should be able to use Mirascripts to download the configuration file before you update and then apply it after updating. I strongly suggest that you do this.

Uh, how many users with the echo problems after the update to 2.86...
I tried to solve the problem with both Diagbox and MIrascript and it doesn't work at all, does anyone have a solution?
I need to go back to one of the previous versions eg 2.85 and test it.
Someone to help me? Any download link for 2.85, or maybe some another versions to try?

[Paul-R]

If you've installed 2.86 then there's no going back to an earlier version.

If you can't get Mirascripts to sort the echo out then you can pay a dealer to download the configuration file for your car from the Stellantis servers in France.

I am willing to try and i think there is a way to forced install.
Can you send me version 2.85 (if possible version 2.85b ) and 2.80.
If I succeed, I will report the solution, it will be of interest to many users

Unfortunately no, it doesn't seem possible to do without a big risk of permanently damaging the device itself. I was not ready for such a risk.
Better not to use phone while driving than to drive in silence without music .
We are waiting for a new update with the hope that it will work better than the current one.

Why do you want to upgrade to 2.80? What problem do have using 2.1?

Hi Paul,

Thanks for your answer.

My bluetooth disconnected permanently : when I listen music mostly. When I'm calling, I have less problems.

If you look at the tables ten posts above this you can see that updating from 2.1 (actually 2.10) is only advised to 2.21 to be good. Any higher version will need a Diagbox session which means going to a Citroen dealer so they can connect to the servers in Paris to download the configuration file for your vehicle. They will charge for this service.

You should be able to use the Mirascripts program to download the current configuration from your vehicle before you go to the higher updates and then upload this configuration to new firmware. This should work although a post above says that they had failure doing this. Mirascripts can also change your configuration (for volume, Bluetooth echo, etc) although I have never done this.

Check your PM for a link to download 2.21. This is a version to load onto a USB stick. Usual disclaimers, use this at your own risk, etc.

Use Mirascripts to download your configuration first just in case of an unforeseen problem. Let us know if this works for you and then, if necessary, I can provide links to later firmware versions.
