Cannot activate Developer Mode - MIB2 - A4B9 - Firmware K3344 #258

Hello to all and many thanks for all infos.

I have an issue with my MIB2 unit on A4 B9 2016... cannot enable developer mode. Few months ago i installed last update K3344 (MHI2_ER_AUG22_K3344, MU vers 1438) and apply patch through GEM and also corrected SVM error. All was fine, except few days before when i observed accidentally that navigation unit, during voice guidance is silent... checked all settings, incl. change language and found that in more than half of database languages are working, except UK-EN, US-EN, ES... It looks like some files are corrupted and i was trying to install last firmware again and observed that i cannot access GEM. I used a clone VAG-COM interface (22.3) and observed that Developer Mode cannot be activated, even after i used security password 20103 (accepted). I used another interface (Launch) with licenced software - same result (parameter out of range). I also ask for help from a certified service with licenced ODIS - online (VAS6154) and even that was not able to activate developer mode...

Now, my question is there is any other way, except direct connection and putty to install firmware ? I think to a custom AIO Firmware that can be installed through RED Menu without GEM...

change to development mode and use 20103.

The code 20103 is not accepted by controller. Adaptation to activate developer mode gives error: value out of range. There are no any faults in any modules... scaned with VCDS, Launch and Odis. I will try with OBD 11 and Delphi but i think it is a hardware issue...

LEL: it was quite incredible but, OBD 11 was able to activate GEM but, after firmware update, developer mode was de-activated... very strange behaviour of MMI controller. Anyway, can close this trouble. Thank you !

Have you tried S12345?

Yes, tried both 20103 and S12345 into a clone VCDS, but also on licenced ODIS and Launch. The controller 5F is not accepting any security security-key.

My main issue is that the unit is not working on english language (Navi & Speech System), all other languages working fine... so I intend to re-install last firmware version (thinking that some files are corrupted) and need to activate user define install through GEM. Can close. Thank you !
