MG4 Software Update Thread

[Pisuke]

@Pisuke I'll help you .

#1: Choose an USB stick up to 32 GBs so you can format it easily with fat32. If your USB stick is larger, use Rufus to format it with fat32 extended.

#2: Go to root directory. It must be blank. Then, please create a folder called Tbox_MPU.

#3: Download correct ...P23EH32 zip-file, extract it and put every file in folder Tbox_MPU.

The structure looks like this:

#4: Follow pdf guide and update again.

Your file structure is wrong. You haven't followed the guide correctly .

First of all, thank you for your help.
The USB drive 64Gb is formatted in exFAT.
If I extract the .zip file (screenshot attached), I get a message saying there are too many files and only one is needed.
If I don't extract it, it says the USB drive isn't recognized.

 

[DonBattino452]

Which message? Where does it come from?

That sounds strange!

I see your USB stick is 64 GBs... Are you sure it's formatted with fat32? I ask this because Windows doesn't offer this by default. You have to use Rufus as a helper app.

It's easier when you use a USB stick with 32 GBs or lower.

Okay, I'll try with a small USB drive.

 

[DonBattino452]

And make Screenshots when you get error messages... it's easier to help then

I tried an 8GB USB drive formatted in FAT32 and the same thing happens, it complains about too many files.
I noticed that when I extract the .zip file, a message appears saying to overwrite F:\Tbox_MPU\root\full\usr\lib\xtables\libxt_DSCP.so, which varies by a few bits.
I'm missing something...

The screenshots say there are multiple files, I can do them but they are in Spanish.

I noticed that when extracting the .zip file, it gets to Tbox_MPU\root\full\usr\lib\xtables\libxt_DSCP.so and an overwrite message appears, which varies by a few bits. I clicked YES. It still doesn't work. I'm missing something...

 

[DonBattino452]

Please show the screenshot. My Spanish is not that bad, it should be A1/A2 level .

Very good... I'll try it again and take a screenshot.
One curious thing when unzipping the .zip file is that many files appear requesting overwriting. Before, I said YES, now I said NO.

Examples of what you request and some more, I have gotten tired and said NO to everything:

I find this very curious...

I'm going to test what happens and I'll let you know.

I made a test to unzip the SNAKP23E32 archive some minutes ago. Everything was fine, I could extract everything without problems on my Samsung Galaxy S23 and copy everything on a USB stick with 16 GBs formatted with fat32.

I think your windows is the problem. Please look at this:

The same error, this is the screenshot.

 

[DonBattino452]

Please show me with your fingers which button you pressed when you were in the engineering menu.

First I select the USB update "Mejora" option and then the MPU T_Box "MPU de la caja Telematica".
The translations leave much to be desired...

 

[tsedge]

Sounds like long filenames being overwritten on an OS that doesn't support them - classic evidence for that.

Instructions

Preparing the USB flash stick via android smartphone (Samsung Galaxy in my case) and putting the files on stick with correct structure. Please follow exactly that way.

Nothing, it's still giving the same error.
One thing I noticed is that it's normal for the "audio/video" option to appear when inserting the USB drive.
I'll try the decompression with another laptop tomorrow.
Thank you so much for your time, I owe you one

Long file names aren't the issue, the issue is with windows doesn't support case sensitive file names
Linux does support case sensitive naming and this zip file has multiple files with the same name in the same folder but due to at least 1 character being a different case it allows it
Tbh I can't remember how I got around it
Android and Linux works, windows I don't think you can make it work
Not tried any apple products but I can imagine Mac will work, no idea with the phones

Edit, added a quick Google screenshot

 

[Pisuke]

Well, after thinking about it a lot in bed, I couldn't resist.

First of all, my thanks for the support you've given me, especially @DonBattino452 and @haloweenhamster.
I tried your advice, remembering that I have a Kali distro which I unzipped, and without any overwrite errors like I had on Windows 10, I tried it again, and the same "error."
As the error message said when updating, "multiple files, I only wanted a single file," it occurred to me to put the FOTA_SNAKP23E32.zip directly in the root of Tbox_MPU, and voila... OK.
I don't understand why the PDF says to extract the files, has something changed?
The process took me 5 minutes at most; at the workshop they told me it would take a whole morning.
Tomorrow I'll have to run SIPS again and finish the job.

 

[DonBattino452]

@Pisuke Thanks for the correction and great job by the way!

The thing is: I made my TBox update in November 25' and I forgot the correct procedure. There are multiple file versions of ...P23EH32 with different file structures. I picked that one that was already ready for being copied to the Tbox_MPU folder without additional extraction. Sorry for that.

You've caught me trying to log into SIPS and I can't get past the damn login screen.

 

[DonBattino452]

Credentials valid?

I just bought an hour pass but it's not working, it's "error".

Can you confirm if the pass is the one to the right of the SNW?
Between the nerves and my Alzheimer's...
I don't remember it from the other day; I have to document everything or I'll forget.
