MG4 Software Update Thread

[the happy bunny]

In your specific case, since you’re still on R16, most of your car’s ECUs are likely severely outdated. Your car should be upgraded via SIPS before attempting any MPU update.

R38 is available online, but as far as I know, R16 is not… meaning there’s no way to roll back.

For both tbox and infotainment (r38 is the current version right now for you) you'll need a computer with a vdi dongle and sips access.

I'd strongly advise against doing just the usb update as you'll definitely encounter bugs

So updating the tbox means both usb and sips? Just found a usb stick labeled tbox under the passenger seat...

Again, I'd strongly encourage not to do so. You'll probably end up with bugs like one of the steering wheel star buttons not working.

Edit: I mean running R38 just via USB update without SIPS reconfiguration to install the MCU software.

my USB upgrade from R05 to R38 seemed to upgrade the MCU (version number displayed at least)?

 

[the happy bunny]

You can update the MCU either via SIPS or USB, but you have to perform both updates separately.

You moved from an Aussie version to a European one. Both versions are highly similar.
I did the opposite job for testing purposes, trying both R05 and R27.

R05 is seriously outdated. It lags about 18 months behind SWI131R27/SWI69R38 in development.

R27/38 are quite similar…

I think I remember you went for R38 instead of R27 because of rear-view camera issues, right?

Just picked up our SE today. I asked before collecting it for confirmation that the Infotainment had the latest update. They assured me it had. However it's on R29 and I thought R38 was the latest for the SE? Is it worth making a fuss? Anyone know what the difference between the two versions is? Cheers

correct. on my first MG i went to R38 via R27 (which is SWI131 so didn't need to disable version check) on my second i went straight to R38 and the MCU updated to same 131.1.3.0 despite it being a SWI69 update

 

[the happy bunny]

What’s the full version number? (It should start with SWI or DBI.)


I’m asking because MY24 and MY25 cars have different release numbers…

It's sw1132-29958-1100R29

is MY25 out already? If so from when and in which countries? I am assured by the sales man that M25 is not out in UK.

 

[leonkernan]

Why roll back? Service place won't care, and probably won't even know what the car was supplied with.

When I had a newer version of the FCIM software to what was on the server for me, SIPS highlighted that specifically.

R38 & R63 have been class as overseas versions which include Australia for release

I would share a screenshot the release info but they now watermark the username which I'd rather not share at the moment

 

[Jonperry64]

I'm only going by the versions actually released out into the "wild". We never saw R29 or R32.

I've got R29!

 

[the happy bunny]

It's sw1132-29958-1100R29

That’s what I thought.

You have a MY24/MY25 car, and your software version is SWI132-29958-1100R29.

It is not the same as R38, which is SWI69-29958-1100R38.

The lower release number doesn’t mean this version is older; it just indicates that it’s the 29th release of SWI132…

 

[Jonperry64]

Thank you. But I'm still not sure if I have the most up to date version!
(ie. Is the 29th release of sw1132 older or newer than the 38th release of sw169?)

 

[the happy bunny]

Well, the two versions belong to different cars, so they can’t be directly compared.

I’m not sure if there’s a more recent release for your car, but MY24 releases are more fluid and responsive.

I've posted this picture before when you've stated there was no R29! This was my Trophy when new in 2022.

 

[the happy bunny]

These are the releases I currently have…

The variant being discussed was the SE.

This mine.

Which is another Trophy version.
