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.

Does SP flash tool not work with a head unit with a front USB port? I don't have the 4 or 6 pin USB connector and it doesn't seem to work with the front port. I may have a dead USB-A to A cable, but I want to confirm.

Is there a way to verify the MediaTek driver is installed post removing the device? I tried another comment's suggestion with holding the reset button (in my case it's a pin hole) and plugging it in during that, but it just restarts and doesn't download on SP Flash Tool.

SP Flash Tool will work with any MediaTek device. However far from all MediaTek devices have compatible, out-of-the-box USB ports. If you don't have the ports shown, this thread is not for you.

Yes, if you watch this video on installing the drivers and get exactly the same outcome, then you're fine.

I found out the USB A to A cable I got is probably dead. I connected an adapter to it and couldn't even get power to my phone. New one ordered.

Unrelated to that, today I did a virus scan on my computer and it detected the file android-terminal-emulator-1-0-70.apk. A VirusTotal scan brings up more results. Can you explain this?

New cable arrived, confirmed it transfers data by hooking it up to my phone. I press start on SP Flash Tool, plug in the USB, and nothing happens. I tried the reset thing too. I also installed the driver twice to make sure I did it correctly. Any advice? This is the correct thread I'm sure, my head unit is YT9216BJ (8227L-DEMO).

That's a false positive. Here's the virus threat report done today on the same file:

Please share pictures of your head unit that show:
  • System Info
  • Front and Rear side of the head unit
  • Kernel version
  • Product Link if available (i.e where did you buy it?)
Example pics so you know what to look for:

Thank you. You should not attempt installing this software package unless you are intentionally trying to rollback to Android 6 API 23.

You have Android 8 API 27 currently. You will find the link to the appropriate mod in thr first post and my signature.

Are you looking to rollback to Android 6?

How do you know it's Android 8 API 27? I'm just looking to get better control over the system.

We work a lot with these head units so we can tell a lot from the pictures you shared. If you look at our signature, you'll find a lot of resources on these types of head units and you can always visit our website to learn more.

I'm just looking to get better control over the system.

Our software packages will certainly help you do that. Just make sure to install the correct one and follow the instructions. If you don't, you will end up with a bricked device.

Here's the thread for Android 8 for YT9216BJ 2/32 GB.

A side note - this package will not work on your head unit as it is made for YT9216BJ 1/16 GB.

So, here is few pics and version of my head unit, still not rooted, i did fix the Wi-Fi signal as its shown on one of this pics jack pin out nr.10 but internet connection still slow and direct Wi-fi i can't get to work even i establish connection between head unit and the phone.
As for the USB wires is the same trouble, the phone connects to the head unit to charge the phone battery, the pop-up request on the phone for data transfer i accepted but i don't see the devices on Myfiles app, so if my USB is not fully functional, i'm afraid i'm confused to root my head unit device in this conditions for now.

First off, this isn't the right thread for you as you have Android 8 API 27.

What you're trying to do, requires modified firmware and root at the very least.

The WiFi speed issues can only be solved with a hardware modification.

How that, it says it's Android 9.1, is that kind of a fake or what!
If so, which rom is suitable for my head unit, or isn't any of them, bcz. I already downloaded this version in hope i would be able to install on my head unit?

    Hello mate,
    Please can you confirm that I am in the right place for my Head-Units.

    Actually, I would like to update it to SUPER MOD but I am afraid to lose it, Please can you support me with this update.

    Yes this package is the correct one. You don't need to worry about ruining your head unit if you follow the instructions.

    If it doesn't work then you can always restore your backup.

    You currently have Android 6 installed (fake Android 10.1).

    If the package doesn't work, after restoring your device, you can try the Android 8 mod. Link is in my signature.

    Thanks a lot for your reply,

    Actually, I am from Syria and you know the situation, the problem is it is very difficult to take of the head unit from the car and connected to power suppler, So can i do it in car with full connecting to the car battery?

    You can but it's not recommended. You will need to connect it only to ignition, not the car battery so that your head unit shuts down completely when you turn off the engine.

    This upgrade will take many hours and you will have to start and shut down the engine many times. That's not good for the car...

    This is why we recommend doing this on your desktop.

    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

      encoder settings.png

    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 !!


    YT9216BJ 8227L System Info.png

    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

    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.

    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.
