Touch screen update keeps showing "Version not compatible with hardware" error.

Hi,

I have a Citroen eC4 shine plus. I recently attempted to use some of the free services on the My Citroen app as the "Charge" & "Climate" services were free. After attempting to use these feature the My Citroen app keeps telling me to update the SW on my car's touchscreen. I then proceeded with downloading the Citroen Update desktop application onto my laptop and used a blank 256GB USB with Citroen update app to do the update on my car. The Citroen update app is download the updates fine and formatting the USB without issue, however, when I actually insert the USB into the USB-C port of my car the car shows a message stating "Version not compatible with hardware" which I am not able to do anything about.

I have asked the a Citroen dealer who have said that I will need to pay them to perform the update, however, I only bought this car 2nd hand a little more than a week ago and unfortunately as this error is not due to an obvious electrical fault in my car so the warranty supplier is not covering it.

Does anyone have any experience with this error and what I can do to resolve this issue?

How old is the vehicle?

You probably have a NAC_EUR_WAVE4 infotainment system and the "Citroën Update" software is wrongly offering the 44.06.44.22_NAC-r0 firmware and the 15.0.0-r0 European map. Both are old versions and have expired signing certificates, that's why you're seeing the generic "version not compatible with hardware" error.

Latest versions for that system are:
* 44.07.33.32_NAC-r0 (that's the only version that could be installed at the moment);
* 17.0.0-r0 European map (but a new version is expected in a couple of months).

To install any of those versions you have to prepare the USB flash drive manually - extract the .tar update file (avoid using WinZip) to a FAT32-formatted USB flash drive.

Windows will by default format a drive bigger than 32gb as NTFS, you have to make sure it's using FAT32.
