MG4 Software Update Thread

Maybe try this : MG4 Software Update Thread | MG4 EV (2022 to 2025) Forum

Take the R41 file named "update."something" and compress with 7zip to a zip file and name it "ficm_soc.zip"

After that try a USB update from engineering menu.

And maybe there's a process we don't know yet or not available with VNCI (require a VCI II)?

Only to be sure I unterstand you correctly:

I should try to take the xxxxxx.51 file which contains the installer.json and the usb_ota_update.zip and rename/rezip it as „ficm_soc.zip“?
Or should I only rename the „usb_ota_update.zip“ to „ficm_soc.zip“?

Rename the .51 file

Didn't work... unfortunately...

Still getting the error:

The package in the root directory of the USB flash disk drive is not detected / recognized correctly. Please check if the package's storage address is correct.

And yet there must be a solution!
There's little documentation on this case.

Have you tried the R36 file instead of the R41 one? Hash problem?

 

[Lanor]

Yes, I also tried the R36.
Same result.

We miss something...
Maybe we'll sort this one day.

There's the problem, the folder structure seems not to follow the previous SWI-branches.

Using the folder AVN_MPU wasn't successful, using the root folder wasn't either.
I also tried a bunch of other folder names...

The installer.json file names the FCIM-MPU folder but doesn't mention AVN, in case that helps.
I'm not familiar with the engineering mode structure of your vehicle, so there might be a new section.
