MG4 Software Update Thread

[wbuczolich]

It is odd maybe something did break somewhere but they've not picked up until dealers start complaining via official channels?

The server status thing doesn't necessarily seem accurate given it shows last up time was in October.

My Ismart is still linked and plugged into my home assistant but obvious Weather maps etc don't work but I don't use anyway.

This server status page seems user-made. The services appear offline, because either MG activated authentication on them, or the login used for checking doesn't work any more. But I sure didn't have any problems one week ago, or the week before that. I don't think that this status page is of much help...

My iSmart is also linked, only the in car apps stopped working (User, Weather), and now, after deactivation, the Navigation-App will not start too.

It seems to be a global (or at least pan-European) issue. I’d suggest avoiding any upgrades, downgrades or factory resets for now if your system is currently activated, as you’ll likely encounter an activation problem.

And we don’t have any idea of when and how this issue will be sorted out.

Maybe the data volume has simply been used up? In the German forum, there’s talk about it being limited to only 1GB per month, and when it’s used up, features like weather and similar services stop working.

1GB per month for 3 years

Amazon Music geht nimma - MG4 Electric Forum

Bei mir hat Amazon Music - aka Online-Musik - bis dato (irgendwann im Sommer) brav getan, jetzt krieg ich bei jedem Lied eine Fehlermeldung..wem gehts auch so?

Yeah I know is that. I used Amazon Music to overcast data limit. But it's the first time unit doesn't connect with Wi-Fi connexion.

Yes, as I said, gladly iSMART still works and it all it matters for me.

Back forth emails with MG but this is an after sales customer service and not Ismart Chinese support. My guess is he don't know and is just pushing towards dealer.

Their answer seems a bit rough.

They omit to mention that factory reset is a feature available to the consumer. They can’t put the blame on you for simply attempting to use it.

Yeah, MG does seem like a bunch of unhelpful or uneducated sales people at least in the UK.

Did some code research in the weather app:
getting weather info from the testsystem (notice the t in front of gateway):

https://tgateway-eu.soimt.com/api.avn/v1/navi/weather/positionInfo

returns a message {"code":1001,"message":"AVN ID does not exist."} which is okay, because i didnt send any payload with my request

doing the same on the production system:

https://gateway-eu.soimt.com/api.avn/v1/navi/weather/positionInfo

gives a http-404-error (not found) . which basically means that the requested service is not installed on the server...

under the activation menu you can switch environment. i think there was a "T" environment with R46, but currently (on R59) i can only switch between P and PP.

edit: the User-App uses these URLs, which are present on the test-system but not on the productive system
@GET("/api.avn/v1/vehicle/admin/basicInfo")
@GET("/api.avn/v1/vehicle/admin/basicInfoV2")
@POST("/api.avn/v1/vehicle/bind/qrcode")
@GET("/api.avn/v1/vehicle/bind/qrcode")
@GET("/api.avn/v1/user/app/installUrl")
@POST("/api.avn/v1/auth/auth/account/logout")

by the way, the ismart remote controll is using a different server, thats probably why it is still working

Going back to r38 on my SE. For now, it seems impossible to get the Plus features working.

It’s maybe just a matter of days…

Hi, I upgraded my SE to R63 and want to downgrade now to R33. Can anyone help how to? The menue on R63 is diffrent then on it was on R33. Thanks

 

[wbuczolich]

go to settings->system
tap 5x on the system version
input 200519
from there you should be able to do the downgrade

 

[bruggerb]

Thank you, I already entered this menue. On the Standart the update was a two step process. Update AVN Vip and update AVN Soc. What do I need to do in the r63 Menue after the input 200519? Thanks

 

[wbuczolich]

"AVN MPU" should be the main OS of the infotainment system
"Infotainment ECU" should be the second part

 

[bruggerb]

With the r33 on the usb drive I get an error when I try to update the AVN MPU.
The ECU updates runs and the Infotaibment confirms the update but stays on the r63. I think the not working MPU downgrade is the problem. Any tips?

 

[wbuczolich]

what error? maybe theres a hidden file in the avn_mpu folder. Only the ota.zip file is allowed in that folder.
Google for "windows show hidden files" to make sure there are no other files in that folder.

Did some more code analysis:

Activation basically checks if the car (VIN) and the infotainment system (Serial Number) belong together.
I'm pretty sure that the VIN and the serial number of the infotainment system can't be deleted that easily, also, if they were, we should get different error messages:

• Lack of VIN number, please contact dealer.
• Lack of SN number, please contact dealer.
• Lack of VIN and SN number, please contact dealer.

So the VIN and the SN are sent to the server, and its the same server that the weather information is fetched from, and we already know that this server is broken.

Good to know, seems something is a bit screwed and hopefully they sort soonish.

hello this evening wanting to watch my version of TBOX... noted:

soc: unknown

any idea?

Tbh you should have read up more before starting as doing things without knowledge is when you'll likely have issues

The info you needed is in this thread

To put SE software like R38 / R33 on a trophy you need to create a folder AVN_MPU and place the OTA zip file inside, if you don't then it won't find a valid update to load

It’s straightforward once you know what to do, but not something you’d guess at first glance.

You can downgrade to either R33 or R38, though I’d recommend the latter.

As mentioned earlier, tap 5 times on the version number in the settings, then enter 200519 passcode.

Next, navigate to the USB update menu, then choose Update AVN.

Here’s the trick with the USB stick:

The update file must be in the AVN_MPU folder only when you’re on a Trophy release, and at root when you’re on a SE release.

So, it’s best to leave the update file at the root and copy it into a folder called AVN_MPU as well.

This is why I always emphasise in my posts to only attempt things you fully understand.

I’ll always be here to help, whether in PMs or in this thread, but it’s far better to assist beforehand!

So, I can place the update.zip in both the root directory and the AVN_MCU folder to use the same USB stick with the SE Engineering Menu and the Trophy’s menu? Good to know for the next time!

I’m going back to r38 tomorrow. This time, I’ve kept the m5d check and vipimage. Hopefully, there won’t be any issues with them.
