SW update for MIB2 infotainment system?

Yes the mib2 standard firmware isn't the bees knees it allows memory mismanagement we did get it once in the Arona. I pinned it down. That was due to embedded JPEGs in the music file being played in the unit. They are suppose to be circa 512x512. You would not expect a large jpeg breaking that parameter to reboot the system.

First I thought it was a corrupt mapcard. Pulled it out, tried another one I'd got, same issue. Not the map card. Next tried it without playing the SD music card, it worked. Then pinned it down to a track / album. It was off the net someone had embedded a 1,000 x 1,000 jpeg image in the track. Well fine on a home system but not on a mib2 standard where the programmer hadn't made an allowance for that. You'd go can I load this image into memory, yes/no. No don't load it in. They had gone yes and had produced memory overflow where it crashes the system.

This issue will come up on mp3 and FLAC libraries. There are programs you can run to delete the embedded jpeg and then put your own image as say cover.jpg in the album directory no bigger than 512×512. I've got a post where I name that program on the board, it was used a lot in the past.

I cover my problem here and solution:


It might be that issue. You have to see whether it reboots not playing music but just navigation. No music or navigation. If rebooting on navigation alone it will be a corrupt SD card. Buy another VAG one. Any brand.

You can put the unit in demo for navigation, under advanced. Engine off and just wait for the unit to reboot. That's what I did in the diagnosis of the issue going through those alternatives.
But there is no Music SD card inside... and no USB...
How can I put a demo or a replace mode if the screen is not touchable? Is there a direct method?
I would like to know if is possible to enter in recovery mode and install a new firmware (also, which is the correct one? the Infotainment is similar at the one in the photo... Seat Leon Xperience 2018).
Thank Yoy so much for the reply

I think at this point you are talking about your friend or have you messed up your own system ?. This is the importance of keeping within train on the updates. The updates are within train not across train. So the units aren't designed to be updated from the train they are on to another. 2* say is the train so if you aim for 5* you get a problem. Some retrofitters sell modified firmware that will go across trains but never the less cause issues. Once broken they have to be taken apart and pins shorted. @East Yorkshire Retrofits historically sorted out a number of board posters that messed up their upgrades via DIY firmware train jumping.

If you aren't prepared to take the unit apart you need to find someone who can to do that pin short. You will find recent conversations on the mib2 standard toolbox on the thread here. Hobbyists that have taken the units apart. Only really recently has the mib2 standard toolbox been discussed here that's where they fiddle with the non standard firmware upgrades. All the rest is were where they didn't follow keeping within train or loosing power during an upgrade then find they can't boot up the unit. The source of that issue is wrong firmware, loss of power during the update or fumbling with the mib2 standard toolbox.

My friend ask me to update his maps, so i Done it downloading from original Seat, but it doesn't works, so, after a couple of trying, maybe I used the OVERALL.NDS file from my SD Navigation.. Maybe is this the problem with his infotainment?
We do not even tried to update the firmware, we only worked on the SD Navigation Card...

He should take a photo of the sticker that is stuck to the unit. The unit can be removed in 5 minutes and there are enough videos to go with it. Everything else is guesswork

Thank you for the answer! The others newest version aren’t useful for my car so?
Is there a risk updating my firmware with the 253T version?
Sorry for the questions, but I’m worried about it because one of my friend have tried to update map navigator for the attached version and now he has problems with using the entire infotainment. It shut down and it doesn’t works for minutes… now even don’t open it… He tried to disconnect the battery for 10 minutes and it worked for a few minutes later, before turning off again... how could he fix it?
Then he bricked the system with wrong firmware or patch. Because navi update you can do by yourself only on MHIG and MHI2 systems. MST2 system works only with SD card and only with the original one iff you didnt patch the unit

Or didnt let the engine run for the whol update. And wich system does he have?

Good morning,
Maybe I explained myself badly.
The 2018 Seat Leon Xperience infotainment (device number 5QA035846A, hardware H30 and software 0359) has startup problems after using maybe the wrong map update on the SD card.
I would need to understand if there is the possibility of restoring and/or updating the infotainment system even though the infotainment itself does not always turn on and does not react. Is there a method to reset the infotainment system remotely?
Update firmware to last version. Navi wont brick your system

It's those youtube video can be dangerous that Mr Fixit puts out. As above get someone to fix the firmware or broken unit. The navigation link provides how to fix it if you lost the overall.nds file but if you have bricked it as above you need to sort that out. People watch those videos but they lead you into a trap.

It's going to be bricked via fumbling the firmware update. Not used allowed firmware train or powered down during the update.

I've tried a lot with my units and done a lot of stupid things with the map material, but I've never been able to damage a device because of it...

How can I update to the latest firmware if I can't start the update via the touch screen? Is there a way to boot the infotainment into recovery mode for the update?
And which firmware update should I safely download?

Can be done in the car but you need to make a cable and a uart serial to usb adapter the right firware and short the pins also putty to open the terminal.

However it sounds like the unit is dead so a corrupt eprom is the probable cause. Lot of faff to fix that one.
