We wanted to share these all-in-one software packages with you, that we put together using various sources as well as our own modifications for Chinese Android Head units with 1Gb RAM and 16Gb FLASH drive, no physical buttons, with screen resolution of 1024x600 px.

  ​

• YT9216B & YT9217B (same package)​

  
  
  

• YT9218CH​

  

Disclaimer
We 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.

2. Proceed to download the software package for your unit and the drivers package in the same folder
   
   
3. It's highly recommended to do these upgrades with your unit connected on your desktop, rather than in the car. Video Guide
   
   
4. Install the Mediatek & ADB drivers on your Windows computer. Video Guide - use the same principle for ADB drivers.
   
   
5. Backup your current system by exporting a full memory dump. Video Guide
   
   
6. Import back your memory dump from step-5 to ensure it fully works. This is how.

6. If successful - try to install the software package again or stay with your original one

IF THIS SOFTWARE PACKAGE HAS BRICKED YOUR HEAD UNIT AND YOU HAVE NO BACKUP AVAILABLE, follow the steps below:

1. Share the pictures of your System Info and Kernel in this thread and I'll try to help you

---------------------------------------

IF YOUR HEAD UNIT HAS 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.

** IF YOU ARE UNABLE TO RESTORE YOUR UNIT, PLEASE CONSIDER DONATING IT TO US @ ExtremeMOD, SO WE CAN BUILD MORE MODS AND TUTORIALS​

Hello, is it true Android 9.1 or fake based on 6.0 ?

 

[ExtremeMOD]

It's 6.0 as most of these units and frankly that's the best version for the hardware otherwise it'll be really slow.

 

[K4f]

Hi,
Could you show us some screenshot / pictures how this Android look like?

How look the radio app?
Google maps run smoothly?

 

[codecxbox]

Sorry if this is off topic.
I have this same unit(purchased a week ago) and the music quality is very bad, very flat, system equalizer doesn't work, Volume 1 is too loud.
I have used viper before on phones connected to head units with great success. After viper is this unit now providing clear sound and bass? My setup is using factory amp.
I am still in my return window and wanted an opinion before rooting or sending it back.

QUOTE=iceblue1980;83842081]Hi all,

Wanted to share this MOD with you that I created for 8227L_demo Android Head unit, model: YT9213AJ with 1Gb RAM and 16Gb FLASH drive. You can use this to debrick your unit or to fully install the latest firmware (Aug2020) with fully working:

YT9213AJ_00011_V001_20200806

ROOT (SuperSU)
TWRP Recovery
Viper4Android / Viper4A / ViperFX
Scatter file (should work for any 8227L YT921xx device)
Full Memory Dump

Download link

How to use

1. Download the file and unzip it onto you PC hard drive
2. Make sure Mediatek drivers are correctly installed on your PC (you can view many guides here on XDA on how to properly install them)
3. Download FlashTool version 5.1824 (or you will get transfer errors with reading DRAM or Scatter file) - if this version doesn't work try other versions between v5.1736 and v5.1916
4. In Flash Tool, 'write to memory' both BOOT1 and ROM_USER file (search for instructions on XDA on ow to import memory dump) using the information from "Memory Map.txt" file (shows what memory values to type in when importing in the Flash Tool) and you will need USB-A cable for this. During this step make sure your head unit is completely disconnected from car battery or any other power source
5. When installation is complete (import can take roughly 20 min), restart the unit in TWRP Recovery mode (use the Shutdown app that came pre-installed with the mod) and in TWRP pick "Wipe Cache / Dalvik".
6. Done!

If you are doing brick recovery, you can follow the very same method with Test Point method also fully described here on XDA Forums.

Enjoy!

Can this work on 2Gb RAM / 32Gb ROM?

Hello!
I have a YT9213A (without last "J"), with 2Gb RAM and 32Gb ROM, and I wish to root it in order to change the radio app with a mod made by a 4pda member.

Can I root it without reflashing the entire firmware?

If not, will yours be compatible with my unit?

EDIT: PS: The download link is not working for me, please fix it.

Thanks in advance.

It's super fast. With this mod you can easily install custom radio app or use one included. Here is a video I made showcasing similar unit but with exactly the same software -

Viper will improve the sound considerably however the main reason for poor sound quality in this unit is the built in amplifier chip which is YD7388 and is absolute crap. If you have basic soldering skills, replace it with TDA7850 and a 10000 UF 25V capacitor and together with Viper, your unit will sound like a very hi end head unit.

You don't "insert" modifications per se or at least this isn't how I did it. I modified everything first and only then performed the memory dump.
