SW update for MIB2 infotainment system?

[Tell]

You'd only need to side step the map SD card authorisation if your map card was corrupted and you couldn't buy another one in your country. In the EU we just buy them off ebay saves the hassle of modding the firmware. The map workaround methods of shifting the overall.nds file defeats mapcare. Only if you wanted specific extras from the toolbox that its worth doing.

As for moving off your train I recall now that defects in the jumped to update were the reason why the poster was trying to get off that version but the defects might have been due to the Turkish firmware sold, so they had bought a mess why they were told to revert. Thus if the firmware works fine stay on it but if the reason to upgrade is that it's not working well, is that you have been sold a pig in a poke. An English expression.

Hi everyone!
I have a Leon X-perience 2015 with MIB2 High.
My actual sw version is: MHI2_ER_SEG11_S0257 which is 0123, this is very old, and my map is old as well, date 2018.
My question is that can i update my firmware one step to MHI2_ER_SEG11_P4709_1_AIO_MU1447_20230320 ?
Than i can update my maps too.
Is there any risk or something won't work after update?
Thank you!

I'm 99% sure that you cannot update in one go, you have to do it in stages.

I found a post about direct upgrade from 0123 to 1447, worked succesfully. LINK
I do not know was it just luck...

I will let one of the experts answer that, @Tell @East Yorkshire Retrofits .

It's the mibsolution.one 1447AIO which has proved durable to big jumps in the releases. The mib2 firmware thread describes the success.

Basically the mib2 enthusiasts using an exploit in mib2 firmware have customised the final release of the mib2 high firmware namely 1447 adding the navigation life long fecs, sports screen, updating gracenotes etc. That they called 147AIO (AIO short for all in one). Normally 1447 would not include life long fecs and the rest.

Series of success with that on the thread with big jumps of firmware which you can't do with the mib2 standard but can with the high.

It's that thread that @MIB-Wiki put up. I did note one poster had the unit hanging after but just needed to interrupt the process. The back end menu can be idiosyncratic. Find that one with a search of 1447 aio pulling the fuse out. Others didnt. Another poster got impatient and said no to mib tools running at the end so didn't get the FeC upgrade, sports screen. Other than that it's worked well on old units as well as new.

Might be the same as above. As said it's the hobbyist group material but has been found to do the job by a number of people

Note, I've re-edited the above since PCBBC implemented a method where you didn't need Obdeleven Pro / VCDS to change the traffic TMC code, they did that within the module. If you do have Obdeleven Pro / VCDS and you are taking the car abroad and want the RR solution, then use option a. Obviously...

That's where the guys on the thread said previously to people "get back on your original train". The modified ones can't be updated further from that point, not in the normal way. I note @leonlad is on 5 series now. I suspect the toolkit helped. Think the Turkish guy left a series of issues around as Polish retrofitters did in the UK in the past. Been there done that. As a few others.

The reliable retrofitter and board sponsor is this one :

MIB2 ZR software updates SEAT

Seat MIB2 software updates

eastyorkshireretrofits.co.uk

I note they ask for the 2xx units to be returned if they want 4xx or 5xx with tiles. It's the way the update works else it may brick the unit. Then you short some pins inside to get it back if DIY it's on the net. There might be techniques which are more DIY to that 2xx to 4xx / 5xx. But if doing it yourself be prepared for it to be bricked and know the way to get it back if not UK based. East Yorkshire have fixed with bricked units from the board before and their associate up there. These were round that Turkish software as I recall. I arrived late to the party. Only the Poles were messing up mib2 highs with their antics in the UK of miss selling map and firmware updates. Those had to be sorted out by East Yorkshire or DIY which had progressed a bit with the mib2 high tool kit and 1447 AIO. The bricked units are an expert or the screws out. Expensive kit to mess up. Mib2 highs are more forgiving with train jumping, mìb2 standards aren't.

yes toolkit and python file that changes a file on the firmware that checks what unit you have so it will run on another older train.

These seat mib2 std units all seems to be the same regardless of part number, i have had 5x running on a 2x unit, i did revert back to 4xxx on a 2xx unit and its been perfect as vcds has no label file for 5x firmware, there was no difference between 4x and 5x that i noticed anyway, but a huge difference from the clunky slow old 2x firmware.
