Yes you can go back down if you wish

I’d strongly recommend exercising great caution before attempting to install these files, particularly if you are unsure whether the original version for your car is included in case you need to revert.

(And take a look a few pages earlier in this thread—I’m a bit of a daredevil when it comes to testing firmware.)


You may want to look in \META-INF\userdata\mulpart.conf

11775918.51 seems to be the archive of SNAKP23E32
11545879.51 seems to be the archive of SNAKP21E32
11533108.51 seems to be the archive of SNAKP0432A
11400605.51 seems to be the archive of SNAKP18E32

yes i checked files also and i m working on 11775918.51 one. cause already i have snakp21e32.

If i am doing correctly, it should work. I ll be notify. Thanks for tips btw

Also if i understand correctly, r59 firmware with snakp23e32 fine. r46 should be snakp21e32 version.but these two versions are operated independently. I can be wrong also.

Hello everyone!
I have a mg4 51 kWh and I updated from R13 to R38. I really liked the new interface etc. but ACC was following the vehicle in front of me closely, even though the adjustable distance was at max. It seemed like this was better in R13. Can I update again to R33 or lower? Of course, whichever one satisfies me with the following distance.

Also, the energy consumption was not working in R38. This situation is also sad.

Doesn't it relate to the distance now being recalled? Change it to level three and it will stick to the larger distance.

Thanks for the advice. It's already at level 3. But when we compare r13 and r38, they made some changes about the following distance.

Did you update it yourself, or was the update carried out at a dealership?

If you upgraded it yourself, it’s possibly a placebo effect, as the ACC is not managed by the MCU/MPU.
(Unless there’s a bug due to the other outdated ECUs)

If the update was performed by the dealer, it’s probably because they also updated other modules directly. In that case, reverting to an older release wouldn’t make any difference.

Minor point that I've mentioned previously so sorry if I'm repeating stuff already known but a handy workaround for the unable to swipe AC controls in carplay is to double tap (switch off and on) the fans and it brings the panel up over Carplay and returns to carplay when you dismiss it.

I know it's not a fix though, just mentioning in case it improves someones day

Why not just use voice commands available with the exception of SE?

Thanks for your answer. I updated it myself. I am adding a picture. But I see a clear difference. It is related to the following distance. I don't think it is a placebo effect. If acc is not managed by mcu/mpu, how is this possible?
By the way, the picture with the consumption is from r13. r38 only has a percentage and it doesn't work properly either, it doesn't show numerical data. Really interesting.

You can open the A/C with a voice command, but you can not close it. By long press of the button on the steering wheel does make AA pop up again.

Is there still a difference between 1, 2 and 3?

 

[Semerkand]

1, 2 ve 3 arasında hala bir fark var mı?

The levels are working properly. There is a difference between them, yes.

 

[Semerkand]

By the way, is it normal that the transition between acc and tja doesn't work in r38? With a long press.
Also it didn't work in r13 either.

Added to the drive

TBOX – Google Drive

drive.google.com

Checked several vins and they have either come up with 1 or 3 files, all 4 are in the drive
View attachment 32803

You can open the files with a zip program like 7zip winrar etc
Never loaded one but would expect that you just extract it to the root of the drive
Here's what MG say

well here is an update:
i tried with this file and prepare usb with how manual said. Result: Upgrade Failed. Correct files are not in usb basically.

So if anyone have a clue, i'm open to ideas.

Btw, i didn't meaning files are broken or misguided, i m sure files are ok, but i didn't make right something. At the moment, i don't have a clue about it.

Do you have both Android and Apple phones in use in your car? If not then those 2 statements are mutually exclusive. (In 1100R38 for the SE there is no pulldown menu when AA/CarPlay is active on the screen. I'd be surprised if 1300R63 was different).

I only have CarPlay.

I have the Pulldown on the CarPlay screen as well as Data Signal, Weather and Radio Information.

Not sure about Android as I don't use it.

Didn't have the pulldown on the older R46? - but now I have it on the R63.

 

[Rolfe]

There is still a difference between 1, 2 and 3, but they made the distances longer. It's not related to the infotainment version because mine changed at the service where they left me on R13.

Semerkand says with R38 the distances were shortened...

 

[siteguru]

I haven't noticed any change in follow difference between R33 and R38 ... and I wouldn't expect to, as this is likely governed by other modules.

 

[NLMGSAN]

And I think the minimum distance is based on the 2 seconds rule, which means it is speed dependent.

I have r46 with AA and the pull down menu visible when AA is active. However, no button to disable lka so I do not need it.

That's why I mentioned the placebo effect... Unless it's the butterfly effect caused by a bug with other outdated modules

I would expect the last one. Although I would not mind having shorter distances. It would greatly help in busy traffic yet without jamming.
