8257 / AC8257 / AC8257_DEMO Android 11 & Android 12 with MCU update
Hi there @texlaws !
I would love to get Android 12 on my device. I asked for it from the supplier and they hacked/faked it on Android 10 lol. I was like uhhh this ain't 12...
But seeing your post, I think I have a headunit that can support Android 12? It looks like I have the 8257 chip. Are you able to tell from my screenshot if my device is compatible with your Android 12 release? Also.. what does dude above me mean it's fake?

By fake i mean it is based on android 11 and not android 12. Although it says Android 12….it is not.
Perfect Android 12 image for me. Very fast Wireless Android Auto, with full 1024*600 resolution (which was not the case with an Android 11 image from another post, it was only 800*480 wireless and 1024*600 wired) Also I had a subwoofer problem with the Android 11 Image, almost no sub before 30/40 volume which was annoying, fixed with this image.
Thanks a lot !
Thanks a lot !

yes and no but know how to fix it before you start.
I need recovey mode to try some of the other firmware i have.
If anyone know how to get into recovery mode, I need the help. and I know nothing about the 360 camera sorry
You should be able to reboot to recovery via terminal emulator. Just type "reboot recovery". You may need a keyboard to navigate. I was able to reboot to recovery that way but I do not have a keyboard with me currently, so I couldn't navigate.
