MG4 Software Update Thread

Yes, you need to put the update.zip file into a folder named AVN_MPU…

Only that or with the other files in root? Like this it will fails

It should not…

How does it fail?

I entered Engineering Mode, then went to USB Update > Infotainment ECU. It checked if I was in P (Park), etc. After a reboot, an error appeared.

USB flashdrive FAT32.

Maybe i will try another USB or only the update.zip without the other files?

You can try:

• to format the USB drive in NTFS
• to downgrade to R38 and then upgrade back to R40

Looks like I’m stuck on version R63 on my MG4 SE.

When I went to the car, I noticed that the display was still on. It had frozen during the first update attempt, and I had to disconnect the 12V battery.

I tried the update multiple times afterwards – even using the R38 package – but nothing worked.

When I tap on “Infotainment ECU” in the update menu, it shows the restart prompt, but the car doesn’t reboot. It just freezes and nothing happens.

When I try “AVN MPU”, it says that more than one update file exists on the USB stick.

I haven’t tested with NTFS formatting, since FAT32 used to work without issues.

So for now, I’ll probably just stick with the R63 version and wait for R67 to be released but my next scheduled service is in five months anyway.

I think part of the problem might be my new MacBook. Back when I used my old Windows PC, the updates from R33 to R38 and R63 worked without any issues!
