Tried a soft reset? What is the coding of bytes 17 and 18?

 

[realtoker]

can u explain soft reset please? I have coding bytes 3, 17 and 18 without any effects

 

[cairus]

Press Power Button, until the unit make a reboot.

And the HEX Code of this Bytes are?

 

[realtoker]

oh yes, I had soft reset.

I tried:
Byte 00 Hex Value = 04 (standard)
Byte 01 Hex Value = 73 (standard)
Byte 02 Hex Value = 02 (standard) and 82
Byte 17 Value = 0, 1 and 2
Byte 18 Value = 1 and 2

 

[cairus]

Try:

Byte 00 = Hex 04
Byte 01 = Hex 73
Byte 02 = Hex 82
Byte 17 = Hex 01
Byte 18 = Hex 01

 

[realtoker]

Try:

Byte 00 = Hex 04
Byte 01 = Hex 73
Byte 02 = Hex 82
Byte 17 = Hex 01
Byte 18 = Hex 01

i will.
But "Byte 02 = Hex 82" isn't it a standard Leon ST? I found "02" for Cupra ST. I'll try it tomorrow

 

[cairus]

want to see if anything happens at all

I'm looking at this thread and this post:

Car image in infotainment

Is there any why to pick inside the current firmware for stored images ? Or Extract them, edit via photoshop and put back Sent from my SM-G965F using Tapatalk

Useful. This shows I think the coding.

The thread was about Cupra Ateca standard mib2 which was fitted to non Europeans models. They just had a missing image but never the less it goes over the key parameters. I passed the VCDS into OBDEleven to get the Ateca Cupra graphics but that image on the thread is the key coding. Needs a little bit of computer science to pass those strings and get the OBDEleven codes... as I recall... I stretched to it .

It's this image on that thread... 5F8 is being shown:

that was also my thought, that the graphics are missing or maybe corrupt.

it' possible if you are hitting the right code ... you do need to reboot the unit after changing that setting. The long on / off hold... did miss that ?.

i will try the whole procedure tomorrow again

 

[realtoker]

Try:

Byte 00 = Hex 04
Byte 01 = Hex 73
Byte 02 = Hex 82
Byte 17 = Hex 01
Byte 18 = Hex 01

You are right. Byte 02 was the problem and i must softreset every time.

but i'm confused.
I had found this pic and there is 047302 for ST Cupra.

In my case 02 is the standard 5-door and 82 is the Cupra ST.
But now its the Facelift shown.

Has anybody a correct list for Byte 02? Is there a the value for pre Facelift Model?

 

[cairus]

According to my information there is no pre-facelift model available anymore

1447 came in as the last mib2 high firmware circa 2019, it was really for that model range at that time. The question one suspects is how far back did they put old images in the library if this wasn't an area the mib2 enthusiasts didn't back fit images. Suspect 2018 on to 2020 would be your lot. Target cars would be where Seat intended to fit the mib2 high.
