Basically your vehicle was shipped with a 'Wave 3' Hardware version of the system. These are compatible with the later Wave 4 systems, but only after what we call a 'bridging firmware' is applied to make them compatible with the future Wave 4 system firmware and map updates.
The issue is that the firmware files are signed with a digital certificate that expires after a certain period - and because your system has not been updated in a timely manner whether by you or a previous owner, the firmware certificate on many of the older firmware files has expired and that is preventing systems in general from being updated.
Try the files above, but if you get the situation where it does not install because of an incompatible hardware error - then you need to contact your dealer and moan to them. Pressure fed back through the dealer network is the only way to get them to release updated versions with new certificates.
I have read all posts but I want a reminder, if is it possible.
I own a Cactus '19 with 31.09.46.62_NAC-r0. I am getting the "Version not compatible with the hardware" error and I reckon it's what you have mentioned so many times.
Should I try my luck with a bridging firmware? Which is this firmware, the latest from Citroen App?
Would you like me to send you my vin number to try or not worthing to try?
I have tried with Citroen Update but no luck.
Thank you.
