Hi,
After struggling hard to find how to update my unit (what doesn't seems possible with USB key in my case ; only with a MicroSD card), I finaly did it.
This new system is Android 11 based, and allow to connect to Android Auto wireless, sounds good uh?

My unit is AC8257 based, and has 8 core, 64 GB ROM, 4 GB LPDDR4 RAM @ 1024x600, but the upload also contains 800x600 & 1280x720px, there is .BAT files that make easyier to pick up the good Android_scatter file.

Here is where I come from first :

And here is where I am now :

Below, a picture of the app/system that detect that my phone is close by and ready to pair with Android Auto. I first had to connect it with wire to show him the way. It now seems automatic.

Hi anyone knows password for diagnostic and engineer mode for this firmware. I think there must be some settings that can resolve quick boot issue. Thanks

Does anyone know if there is an apk I can just install on the head unit to get wireless android auto working rather than having to reflash new firmware on to it please?

Thanks the firmware, unfortunately won't install on my headunit, current have the following 2610 version installed IL1G0104-P10-2.1.2.1.2_20220614_092407

Is there a newer one available that fastboot works on? Or is there a way to force it to downgrade to this one you've posted?
