MG4 Software Update Thread

[tommasov]

I had my Trophy upgraded to the latest software the other day and I've just realised the garage left the USB in my car. If it's of any help I can upload the files if anyone wants to try doing it for themselves?

Wow please share, as a developer I would love to learn more about it

Apart from accessing the engineering menu does anyone know what the procedure is, do you need to depress the brake pedal to put the car in ready mode or is just sitting in the car to wake it up enough before starting the installation?

It tells you what to do when you are in engineering menu. The car needs to be in ready mode so yes you need to depress the brake pedal.

In any case I do not think we will get the firmware ….

Is it the firmware CPU update or AVN MPU update option

.......so, who will be the first person brave enough to install?

checksoc.txt indicates that the file is R46:
SWI68-29958-1300R46

@BobbyBrown can you confirm that your vehicle has R46 (not R59)?

Don't know if it still applies but originally you had to make sure nobody was sitting in the driver's seat when doing an upgrade or it could brick the system - dealers learned this early on.

That was related to software/firmware upgrades as I understood. A map update is just pumping new data in.

@BobbyBrown was very kind to share the files with me

I have them on my google drive and can share a link to them for anyone who is interested but use them at your own risk! As I mentioned before, you could completely brick your car

Thanks @BobbyBrown and @Deanicus

The fun has begun!

If the brake pedal needed to be depressed to wake the car up, would they then have to get out and move over to the passenger seat to continue?

Anyone used to playing with Android Phone firmwares will find this very very familiar.
How long before someone changes their boot screen?

Yes. Caught them out early on as the obvious thing to do was to sit in the driver's seat with the laptop connected doing updates.

I don't know if this is still relevant (bug now fixed?), nor whether it was just certain updates that had this problem but it did come up in the early days.

Curious what program you are using there?

Also it would be worth checking the service manual to see if there is a recommended procedure.

Once you've unpacked the payload.bin file, it's older but Ext2Read handles those image files fine.

Ext2Read

Download Ext2Read for free. Ext2Read is an explorer like utility to explore ext2/ext3/ext4 files. It now supports LVM2 and EXT4 extents.

Presumably (looking at your directory tree image above), background wallpapers and fonts can be changed too.

Possibly, although the launcher seems to be very custom so I doubt the normal Android methods will apply.

Be nice to change the car images to match the actual colour of your car!

You could always paint the top of your car white
