Turbo Quattro

Hallo, bad news :-(
Reflashing of efs-persist was vain.

I succesfully flashed using the backup I done this morning from my 3GP version 666.
Then I restarted, waited the complete boot and after a minute I restarted. I boot/restarded a couple of times.
But the main unit is still broken: it starts ...

Perfect! Backup done!
I created the SD with the script, and just to be sure that the SD path was correct, I modified in:
cat /dev/fs0p3 > $dstPath/efs-persist.efs

I understand why the efs-persist image is not shareable: it's full of semi-personal data (addresses, name of paired phones, address book ...

To extract the efs-persist image, the only main unit I have is a 3GP "666" (8R1035666): it's on my car.
I have read (on another post by you, this ) that it's possible to use a script on a SD card.

Can you tell me how to create the SD card and how to launch the script? (I'm sorry but I never created ...

Thank you, I will try tomorrow.
But just in case, is there a efs-persist image inside the SD that I can flash?
What would be the command?
See you soon

Hello all
anyone has an idea about how to rebirth my MMI?
Thank you

Hello Tschako, I've tried as suggested.
Reconnected the DVD, started in IPL mode, deleted headers and installed the 767 fw from the SD.

But as you can read in the logs, there are no steps forward :-(
I reconnected also the ...

Thank you Tschako!
Just to be sure that I will do exactly what you suggest:
1) I will reconnect the DVD (I will leave the HDD disconnected)
2) I will delete the header at 680000hex with " flashit -a 680000 -e 1000"
3) I will delete also the FPGA header with "flashit -a 40000 -e 1000"
4) then I will ...

Hi all
I tried to boot without HDD and DVD.
System connected to MOST.

As you can see in the log, MMI don't complete the boot.
The display is completely black and shows only the Audi logo for 2 seconds at start (as before).

From the inside of MMI, I ...

It's strange because it was connected to the car bus system. All cables were connected, and the car bus system is ok because it mounts a 3GP unit (8R1035666, without SIM slot).
Maybe the MOST connector is faulty?
How can I check if the optical ports are working?
Thank you for your help and also for ...

Hello,
there is an update.
In IPL mode, doing a SCAN command I see a checksum error on BIOS.
And the IFS headers are named "old".

Hello all
I am trying to revive an MMI 3GP (8R1035670G) that probably was updated badly (I suppose an attempt to update the maps).
The behavior is this: the central unit starts, appears for a few seconds, the Audi logo appear on the display but the button lights remain off, and after a few seconds ...
