I already opened it to enter to recovery mode. I will try to 'extract' OTG port. Meantime I contacted with navifly. They said that will send new FW via email. Still waiting for it.

Thank you anyway for your tip's

Any... it is you who have to decide what you want. Any decent USB DAC will be much better than Android's.

try to encode the standard head unit first, so as not to use the aux cord

Possible for CIC iDrive? Tks.

Yes

Headunit:
block 3000 HMI:
CDMM_AUX_HU = aktiv
block 3003 TELEFON_TELEMATIK_ONLINE:
CDMM_USB_AUDIO_SINGLE = nicht_aktiv
CDMM_USB_AUDIO_DOUBLE = nicht_aktiv

UPD:

Everyone should have the KSW Toolkit

Client https://github.com/Snaggly/KSW-ToolK...eases/tag/v1.1
Service https://github.com/Snaggly/KSW-ToolK...ses/tag/v1.1.0

After installation, run the program
In the program, start service, enable autorun at startup
After that, go to - System tweaks
And turn on - Sound Restorer to keep sound running on OEM side

May I know how do I do this pls? Tks.

Using this program will take no more than 2 minutes https://bimmercode.app

Not to be confused with bimmerlink. Bimmerlink is used for diagnostics

Or any other bmw coding program

Or visit a diagnostician who has at least some coding knowledge

P.S. the aux in the armrest and the regular USB (OEM BMW) stops working (charging via USB will work).
The point here is that only the multimedia block is encoded so that the aux will work directly from it. This encoding is for E/F series bmw CIC+Combox or CIC+Mulf2High or Entry+Combox.

In the case of CCC+Combox or CCC+Mulf2High, it is necessary to select aux_config in the CAPPL block and put mounted. A second AUX item will be added to the menu, through which the sound will go in android.

Headunit:
block CCC_ECUS:
AUX_CONFIG = Mounted

Is this reversible? Just in case I mess it up.

So with this I don't have to connect the DAC AUX to the AUX under the armrest right?

Thanks!

Of course reversible BMW can be rolled back to the factory at any time.
Any encoding begins with saving the encoding data. Some programs do this by default after changing and saving. So that you can go back if something went wrong with you And in this case, to remember the data before the change, I don't think it will cause difficulties to manually return it back after.

You don't need to connect anything to the AUX connector in the armrest.

Hi,

Finally I restored OS in my HU.
U used this tool: https://github.com/libxzr/FastbootEnhance
This tool is realy good GUI for fastboot.
Evan me, withou tbig knowledge about it i was able to understand what is going on with my HU.
The problem was unsuccessful update.
It stuck in "Snapshoted" state (https://source.android.com/docs/core...l_ab/implement)
I had just cancell previous update using button and then switch A/B partitions.
After that HU started with previously sucessfull installed FW.

Thank you for your help.

Best regards,
Jacek

Unless that 6+128 is not a Snapdragon 662 or KSW unit. Which is also possible.

Can you please support with how to upgrade to ID8 UI?
My unit is bought from navifly
I upgraded to firmware version 2.4.4 already

Sometimes I feel like a glorified link reposter... it would have been so much easier if people actually read these posts or use search function, but here we are.

Try using SD card recovery. In most cases, this is enough. Unless, of course, the android loader was blown to smithereens. This method has been described more than once on the forum pages

I'm glad you did it.Sometimes an additional change from R to S helps to return the original state of A 11 in case of an unsuccessful upgrade to A12. Here is a description of the methods. Including, do not rename. First they try it from a flash drive. It does not work, switch to recovery mode. From simple to complex. It all depends on the neglect of the case. Sometimes it happens that a lot of knowledge only aggravates the situation .
