MG4 Secret Menu Mode...

[siteguru]

And to access that menu (before the 5x tap) just press on the phone icon, select the keypad, and then enter the code ... you don't need to hit the Dial button, as soon as you enter the last * the menu pops up.

Anyone have any ideas as to what the other codes for the engineer mode on previous cars are? This might give us some insight!

 

[siteguru]

The Trophy code is 200519, but it has a different method to reach the Engineer menu. We still don't know the secret code for the SE.

Very interesting stuff here Secret menu Mk2 - Pin

Interesting ... but no good for SE owners as there's no data connection unlike there is on the Trophy. (Unless the eSIM happens to work for the Infotainment unit rather than only providing the data connection to MG's servers).

So how does that number relate to the trophy? Release date maybe?

Ignore the release date bit. I’m just trying to figure out the correlation of codes!

One theory is that it's the date of birth of the SAIC Chairman/President/Whatever's granddaughter.

He's done kinda what i'm trying to do, except we can't turn on ADB in the MG4 51 yet.
My concern is that older cars ask for a pincode (the 200519) but the SE/Excite asks for a Password instead.

Pretty sure I could do that trick in a Trophy/Essence/whatever since we've known how to get into those for a while now..

It's interesting in the workshop manuals, the higher end system is called "SAIC1.0+" while the basic system is called "Color Radio"
(and yes, i've already tried that, mulan, saic and a bunch of other things as the password)

 

[siteguru]

In the General Workshop Procedures the only passwords that are mentioned are the two we already know ... the password after clicking the bottom-right 5 times isn't mentioned. (Has anyone tried the same SE code again in that prompt?)

Confirm both and I’ll give them a try. I did try the 200*** number!

Getting further into the android system but no joy on the password!

Wondered if we've got any further with it.

The code for the SE is now known - see below. I think I posted screen grabs in my 1100R33 thread of what we can access.

Open the phone icon in the car.
Select the keyboard then enter the following - the Engineer screen
should pop up when you press the last character:

#*#4479*#*

I'll have a play!

Open the phone tile in the car.
Select the keyboard then enter the following - the Engineer screen
should pop up when you press the last character:

#*#4479*#*

But this isn’t for the bottom right 5 times menu, this is just the lower version - still working on the code!

 

[siteguru]

Correct - the additional password is as of yet unknown.

@siteguru Correct - the additional password is as of yet unknown

## has the opposite "mirror" pattern to *#, so perhaps that is a clue.
A lot of people chose pin numbers on the basis of patterns that resonate with them for some reason.
4479 is, on a key pad, 2 of the left middle, then the digit below followed by the end digit on that line.
So I'd be looking at the likes of 6631,6697,4413, 1146, 3364, 9931 etc.
Then flip them if needed so 4479 becomes 4413, 6697 becomes 6631, etc.
Easy enough to write a little bit of code to come up with these kind of patterns to try.

Cool

The most likely way we’ll get it is by disassembling the APK files. Either by getting hold of an infotainment update file or by pulling them from another system where we already have ADB access.
The ZS EV mk2 guys already have ADB access to their system which is almost identical, I’m hoping one of them share the files from their car and MG used the same code.

What surprises me is the lack of Carista support. That's a Bluetooth dongle that allows supported cars to have modifications. For example, I had a Seat Altea XL and you could alter the following:
Automatic Light Threshold.
Set Indicators to side marker function as well as indicate.
Switch cornering lights on off
Alarm on off
Alarm lights or horn or both
One touch windows upon holding door locked on remote.
Automatic sunroof closure upon rain
Fault diagnosis
