Access to Green Menu on MMI 3G Basic

ZTAudi  Access to Green Menu on MMI 3G Basic
Hi all....

Anybody know how to activate the secret menu on an MMI3G Basic unit without access to VCDS/VAS to enable it?

The unit is bricked (getting red screen) following a botched firmware update. It isn't communicating with VCDS/VAGCOM or VAS so I can't enable the green menu to put it into Emergency Update mode.

When I switch on the ignition I get a green screen, immediately followed by a red screen with this text:
MMI3G EmApp 22.27.1642
MU9303
Trigger Shutdown in XX sec!
(xx counts down from 60 to 0)
Mount Error (Or Metainfo CRC Error if I have an SD card in the slot)
Update Failed! Trigger shutdown after countdown.

Alternatively, I may try and re-flash it but this would be a last resort.

Any help would be greatly appreciated.

Try putting the firmware that you were trying to update to an a sd card and put it into the unit.

Tried that...no luck. So i picked up a head unit on flea bay, installed it and had dealer remove component protection. However the firmware that's on it is 3G_DAB_K0098.
Can i update this to BNav_EU_K0257_2_D1 (my radio doesnt have DAB) as i want to install 2015 maps?

Thanks for the advice!

It was entirely my own fault that the unit was bricked.

I was installing version K206 which I had downloaded.

Can i update the new unit from 3G_DAB_K0098 to BNav_EU_K0257_2_D1?? (Of course, I will enable the green menu first!)

Can anybody give me the specs on the edge connector needed to connect to the main PCB on the head unit? Or better still, a manufacturer and reference number??
