Hi Guys!

I have problem with MMI 3g High unit in Audi A4 B8 2010MY.

Buy car with death unit, and now try to fix it.

MMI Screen was completly black after ignition turning on.

I connect ftdi using instruction by Keldo and got log which finish: |OnOff: error Metainfo CRC error!!!
I tried different versions of softwares, but none working with that unit.
Still got RED screen with message "Metainfo CRC Error"

What i can do to fix that unit?

Thank you very much for help!

Here's completly log from putty:

You need SD HNav_EU_K0022_2_D1
Put that SD in slot one and reboot.
Auto recovery should be able to finish.

[Rashk999]

why that so old  firmware, put FW HNav_EU_K0257_6_D1

[TechniX]

I have tried both sw 022 and 257, and any doesen't fit - still Metainfo CRC Error

[Rashk999]

this line 

MetafileChecksum = "SOMETHING"

delete and paste this line

skipMetaCRC = "true"

in root folder metainfo2.txt file

[congo11]

why that so old  firmware, put FW HNav_EU_K0257_6_D1

Because update with that firmware was started earlier and now unit wants this one. That's why.
Unit now search for meta info with that checksum -> update.txt: MetafileCRC = D6945337
But it looks like the software SD they used is not stock as that CRC is not from stock SD or it's not K0022.

[TechniX]

Still the same - Metainfo CRC error.
In attachment modificated metainfo2.txt from 022 SW and LOG from Putty
Thank you very much for help 

[Rashk999]

EnableUserDefinedSWDLMode = "true"

try add this line above crc skip line

[TechniX]

Still the same.

Try to overwrite with : MetafileChecksum = "D6945337" when it is not already the MetafileChecksum from your SD Card. Or try with the two other ones then : 963512b2 and 7282f817

they must not be right at this moment, because

One Guy named CarFreak (worked together with keldo) wrote once: (translated)

The 3G / 3GP (5F) in Emergency Mode accepts only the last used source like used before (SD1 / SD2 / DVD) so when a DVD was used, a SD Card use is not possible and only with the last used checksum when it failed. So be careful and save the last used checksum from metainfo2.txt on a secure place, when entering red EmergencyMode. So it is possible to bring the 3G/3GP Unit out of the EmergencyMode with this checksum.

As your 3G gives us these 3 checksums before starting with metainfo2.txt reading, then you can try to replace with them, no matter if the checksum is right at that moment. maybe it helps!
