You need to deal with MMI eeprom to be able to update..
Someone updated my MMI to K3344, he connected with a D-Link DUB-E100 Ethernet adaptor to the USB port via telnet / putty

@aberbic you should add it on the first post of the VC and repo thread.

@Clixt I'm guessing you haven't actually used that site. Check it out and I'm sure you won't find it as useful as it appears to be.

Thanks for the replies and information. My current train is not listed as a supported train in the metainfo file. I have minimal access to any sort of scan tool, but Carista says:
Infotainment system
Part #: 8W0035880F
Component: MU-P-LNS-US


Is the component equal to the variant listed in the metainfo file?

Does anyone know what SupportedTrains means exactly? Does it mean you are supposed to install the updates in that order or does it just mean you can use any of those updates on your mmi?

It's could be either. Sometimes to get to a version, you need to install the intermediate versions because that's the defined upgrade path. But other times, it just means that you can't upgrade. Think of it as Tracks rather than Trains.
Audi has determined a safe upgrade route which is written into the meta file. Some people are so confident that a certain version will work on their hardware, so what they do is update the eeprom of their current hardware with a version number that the normal update process will accept.

Go to your MMI information screen and see what version you have installed. You can also see this in the Version Information screen on the Red Menu. You dont need a scan tool for that.
But tbh if you don't have a decent scan tool, it tells me that you aren't into messing about. I wouldn't update the firmware then, if I were you.
