You might need GEM (Green engineering menu) activated and use User Defined Mode and manually select all that is under AUDI_MMI3G_ECE if it's not selected.
Warning - FW update K0900 is removing the "Emergency Update" option from the "Green Menu".
• Emergency menu activation on K0900 firmware. [ Only for A5OC ] Download
• To enable the Green Menu you could use VCDS, VAS or the following script [ Green menu activation ] Download
• 03623 [ 03623 Remove ] Download
1. Unzip it on the SD card.
2. Put the sd card in the MMI.
3. When prompted press the center knob.
4. After the script is done you will see confirmation screen.
5. Remove the SD card and reboot MMI
Do not use MAC to unpack and/or copy the files to the SD card.
The problem:
I've tried to update my firmware (MMI 3G+) to K0767 and got the following error:
GEMMI_nav:0 error code 141
I could only access "Retry" choice (but update kept blocking at 5% with the same error) or "Back" button that was useless
Unable to do anything else, even the Reset procedure didn't work!
Root cause:
This is a file corruption error, the MMI didn't like what it found on the SD card.
Because I'm a stupid software engineer who thinks he knows best, I didn't trust the forums and copied the files from my mac onto the SD card (using command line to clean-up the .Trashes/ and alike folders)
So this is the lesson: DO NOT COPY FROM A MAC
Sub-lesson: better learn from other's mistakes than redo the experience...
Solution:
As stated previously, even a MMI reset procedure didn't allow me to get out of the error.
So I went to my neighbour's Windows PC, reformatted the SD card and extracted the RAR archive onto it.
Back to the car, update went fine and completed successfully after 30 minutes
LESSONS LEARNED - NEVER USE MAC OS (or Unix, Linux based OS) for unpack and copy map or firmware data into SD card. Also always format SD card in Windows OS. USE ONLY WINDOWS FOR UNPACK/COPY!!
upgrade Firmware as well. I could not load map data even they were copied in windows. It means that also Firmware was corrupted.
I found cca 10 000 hidden files on Firmware SD card. Dangerous is that Firmware seemed to be OK all the time but it was not and I could destroy whole MMI
(Imagine that FPGA or EEPROM is burned with some hidden apple .bin file....).
Q&A section
Here are some of the questions raised by the forum members about the update process that I might failed to explain in the manual.
Q. Do i need VCDS to do the update?
A. No, you need VCDS only to clear some errors after the update but the MMI will function correctly even if you don’t clear them out.
Q. I have a Bang & Olufsen sound system not a Bose. Does this also mean that i need to exclude it?
A. Yes, better not to update the DSP system.
Q. Currently no updates for North America?
A. Not for now.
Q. I have mmi 3gp , version p0XXX can i go straight to k0900?
A. Yes.
Q. Have found the activation script and it includes "2380_00040009.fsc". This should be changed according to manual Page 31 to the MAC address specifically to my MMI or should I continue to use the "2380_00040009.fsc" as stated in the manual page 18.
A. Leave the filename as it is now.
Q. The 2380_00040009.fsc file contains a VIN number. Should that be changed to my VIN number?
A. No, do not attempt the edit the fsc file.
Q. Will my VIN be visible and correct in the MMI
A. Yes.
Q. Only thing is that my Google Maps option is greyed out... any hints?
A. Reinstall the GEMMI_nav component from the K0900.
Q. 01043 - Control Module; Incorrect Software Version - How can i solve this ?
A. Restart the MMI and remove the key from ignition then put it back in. The error should change from 01043 - Control Module; Incorrect Software Version to 03276 - Please Check Software Version Management.
Q. What does the new firmware bring in terms of added functionality?
A. Not much, apart from K0770/K0767 fixing the issues with the SIM data connection and Bluetooth usage at the same time.
Q. What are 03276 and 03175, will they affect the MMI in anyway and how can they be avoided?
A. 03276 - Please Check Software Version Management will appear every time when the software is updated w/o VAS connection to the VW/Audi servers.
03175 - Invalid Data Set will appear when updating the map w/o deleting it first. Sometimes this helps to avoid that error.
They will not affect the functionality or the sound characteristics of the MMI.
Q. Is there a way to use used defined mode w/o "Green Menu"?
A. Yes. In file metainfo2.txt in the root folder if you remove the line "MetafileChecksum=XXXXXX" and add
EnableUserDefinedSWDLMode = "true"
skipMetaCRC = "true"
the you will be able to use the user mode w/o the green menu.
