Is it possible to update android 6 YT9216B to this android 8 version ??

Possible? Yes. But I wouldn't recommend it unless you really know what you're doing. This will require a specific Android 8 bootloader file unique to your head unit.

Frankly, Android 6 is better by far, when it comes to my mods for compatible YT921xx devices.

Also bear in mind that YT9216BJ package is not compatible with YT9216B head units. Please visit my super mod thread for your particular model. Check my signature.

I cannot get my TPMS sensors to work with my yt9216bj AHU. I downloaded a BLE app and it never locates a device. Same app works on my android phone. Is there a setting or a driver that I need to install? I'm running android 9.1 car edition, kernel 3.18.79, API 28. All other bluetooth devices will connect (phone, ELM327).

Wrong thread I'm afraid. I only provide support on my mods.

Sorry, I'll repost in another thread. I watched your video and it is the best instructional video I have found on XDA. I bought a spare AHU because it went down to $89 on Amazon. I will follow your instructions and try it on my spare before the one in my car. Keep up the good work!!!

Hi all,

If you want to greatly improve the way your head unit works, sounds and looks like - you've come to the right place!

Why install this?
With this package you will greatly improve:
  • Stability
  • Speed
  • User Interface
  • Sound tweaking options
  • Customization options
Following my previous Super MOD guide, I have now completed a new project, this time on a newer YT9216BJ head unit running the Android 6 API23 operating system (fake Android 8.1, 9.0 and 9.1).
If your head unit is Android 8 API 27 (fake Android 10 or 11), proceed to
this guide instead.

This guide is for YT9216BJ units with 1 Gb RAM and 16Gb flash with no physical buttons*.
  • ON PHYSICAL BUTTONS: this software has only been tested on head units with no physical buttons (like volume) | Before making any changes, access the CAR SETTINGS -> FACTORY SETTINGS -> ENCODER SETTINGS on your head unit and take a screenshot of the current settings (see example below). After installing the package, go back to these settings and adjust them if needed. If that doesn't help and if you can't successfully re-calibrate the buttons after installing the firmware, restore your backup

Do not use this package if your unit is "HIFI" or has a separate radio chip installed (A or NXP series)


!! TAKE A PICTURE OF YOUR SYSTEM INFO AND KERNEL VERSION BEFORE DOING ANYTHING TO YOUR HEAD UNIT !!

Disclaimer

I do not create the software itself but rather use research and put together different mods and hacks into one package that includes very user-friendly step-by-step instructions on how to install it all. You will find the links to original posts in the instructions pdf's if credit is due. The software might include smaller changes made by me and has been fully tested in real units.

The Software Package contains:

  • Custom Android 6 firmware for YT9216BJ
  • ROOT (SuperSU)
  • TWRP Recovery
  • Viper4Android / Viper4A / ViperFX
  • Custom UI (Car Launcher)
  • Custom Boot Animation

Hi mod Iceblue1980, i got a head unit for my bmw320d e46 no hard buttons, the XY AUTO, YT9216BJ and android 9.1 on it. My concern about my head unit is few to mention, the wi-fi areal is very low, hardly connect to wireless router at about 3-4.mtr, or direct wi-fi appears but not functional, and i face lag's on maps and music player a bit, so i am willing to downgrade to this android room v.6.1 if you recommend me that, and if you think this will solve my wi-fi troubles.
I tried to locate a hardware wi-fi external antenna pins but no success, so if you have any idea, would you show me on pic please.😊
Btw, i have some knowledge on flashing rom's on samy android phones.

Yeah, the head unit is the same with this one on video link, and i already downloaded the rum and tools, i just have to find USB cable to plug in, but my question. is, will it have better wi-fi performance and longer signal area connection or not?
To improve Wifi (and subsequently BlueTooth), a hardware modification is required. You need to install a WIFI antenna. I plan to record a video guide on this mod soon.

    Please, it would be great, i already have open head unit few times to find out where is the external antenna pin print so i can connect external antenna wire that i have from other broken Laptops, but no lucky.
    The Bluetooth works fine.

    There are a number of different ways to do it but we prefer our way which generates much more stable operations. Follow us on YouTube to get notified when new content comes out.

    Do you know of a way to get live wallpapers working?

    Normally I just change to full on black wallpaper so that it blends in when you switch between apps.

    With the Car Launcher, you won't see the wallpaper at all other than when switching between the apps.

    Can my unit follow this guide or should I follow another One?View attachment 5389371

    I would probably recommend the Android 8 software package instead.

    Do think any other mod of your work in this unit ?
    None of my mods will work on your unit without alteration, I'm afraid.
