MG4 Software Update Thread

[the happy bunny]

Here's a quick recap:

For MY22 and MY23:
SWI68 = Trophy (UK) / Luxury (EU) + X-Power
SWI69 = SE, SE LR (UK) / Standard, Comfort (EU)
SWI86 = Standard (Thailand)
SWI131 = Excite (AUS-NZ)
SWI171 = Standard (Indonesia)

29958 = MG4

1100 = Standard, Comfort, SE, Excite
1300 = Luxury, Trophy, X-Power, Essence

Rxx = Release version

For MY24:
It’s an entirely different set of versions, not directly comparable to MY22/MY23 releases.

Is infotainment different too, or just versioning?

 

[PeteC]

The variant being discussed was the SE.

Ooops!

 

[the happy bunny]

SWI68, SWI69, and SWI131 share the same hardware, including GPS and Wi-Fi connectivity. This means it’s possible to install Trophy releases on an SE or run Australian software on a European car without any issues.

However, SWI86 and SWI171, while based on the same system, have some hard or soft differences/limitations. Technically, you can install Indonesian or Thai releases on a European car, but GPS and connectivity functions will not work at all.

For MY24 cars, I really don’t know…

My friends just took delivery of a new Trophy LR which is presumably MY24 (at least).
The software version is:
SWI133-29176-1300R30

 

[the happy bunny]

Yep, it looks like SWI133 is for Trophy models, while SWI132 is for SE versions.

29176 also shows MY24 are largely revamped cars…

 

[hojnikb]

Is base android still 9.0 or did MG upgrade that for newer cars?

 

[the happy bunny]

I’m not sure if MY24 cars are running a newer version of Android.

But don’t think of Android 9 as outdated. it definitely is obsolete for a phone or a tablet, but not necessarily for an automotive infotainment system.
In these systems, Android serves as a low-level layer, with the entire operating environment built on top of it, a bit like a comprehensive launcher.

That’s why they use simple, fast and stable base systems.

android 10+ would be great, as that would enable additional APIs for natively run ABPR to pull data from the car directly (instead of using enode or OBD).

 

[the happy bunny]

For engineers designing a closed system, this is not a major concern, they just want a stable version that meets basic requirements. They prioritise reliability over having the latest software. They don’t need advanced ressource-hungry APIs (especially since the hardware is relatively modest, with only 4 gigs of memory and an old CPU)

Using a more recent version of Android could also make it harder for us to access the base system.

But for an internet connected system not getting any software updates. It's a security nightmare.

 

[the happy bunny]

Yeah, security is definitely an open question here.

When it’s this easy to access the Android base system, install unauthorised apps, and update with other versions, it raises concerns about potential vulnerabilities.

It’s surprising that there aren’t more restrictions in place.

Hello, having taken the responsibility of updating my MG4SE directly from R16 to R33, I’m giving you a quick update regarding this and thank you for your support: improved fluidity and numerous bugs fixed, much faster connection with i-Smart and functional startup with i-Smart, everything seems to be working correctly, including the shortcuts. The significant improvement is, of course, the presence of distance with the reverse radars and the much more practical heating menu, even though the design is less appealing. The loss of a menu in the sound system is a regression (“3D sound”), but it was never used anyway. Obviously, I still have my heating problem, but I have an appointment at the dealership to fix it along with the “LKA.” On the other hand, the problem with DAB radio display is not fixed by this update, or perhaps a separate module update is required? I also wonder about the “touch” update visible in the engineer menu since my version is very old. Once again, I thank all contributors. Thanks, thanks, thanks!

3D sound option comes back in 1100R38.

Together with an HVAC module update, 1100R38 greatly improves the HVAC system and resets the temperature range and target setting to what we would expect.

So, want 21°C ambient temperature? Before the latest updates you'd have to set a target of 24 or 25°C; afterwards you can set 21°C.

 

[Rolfe]

Good.

 

[rod93]

However, false hope—the start-up with the phone does not work. I think an update of the T-box is necessary...

 

[N80SSM]

Dropped mine off at garage this morning, told the tech literally nothing works properly. He seemed to appreciate what I was saying, let's see what they do with it

 

[N80SSM]

So got it back, they claim to have updated lkas/adas systems and lka and acc did seem a little better on drove home, if anything I'd say a little unresponsive as I was on the white lines and it wasn't alarming. How do I know what they have actually done? I also tried TJA and it was as useless/dangerous as ever. I don't have the new option to disable lka in the drop down menu so does this mean I don't have the r59 update? They also claimed i already have the latest infotainment, but again not convinced by this, pic attached.

Not sure you can check the LKA but my LR is on R63 for info version.

 

[Dhaerha]

hi, i have a mg4 trophy 77kWh, EU version.
the current software version i have is SWI68-29958-1300R40
so as far i can understand i can update to R59 (or r63?), i need only the "r59" update file and use USB? all the module like TBOX MCU end so on are updated by the R59? or it's infotainment only? and i have/need(?) to update others module too?

thanks.
