Yes, you used the wrong Updatefile. Now you must find the right Softwarepackage and install it from the scratch.

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!

No Sound issue Update:

The vehicle had an oe amp, which the head unit had to turn on via blue ( ant wire) after the update it would not send a signal to the factory amp but would send if the fm radio app was on, hence the radio had sound and music app did not. ( very weird issue, every worked before the mod )

Solution:

removed the oem amp turn on wire from head unit antenna wire. Reconnected to the red ACC wire ( the amp will turn of when key is on )

FYI: The vehicle installed on is a 2008 Honda Element EX

Hola amigos
Disculpe la traducción al inglés, soy hispanohablante.
Tengo una radio china de modelo: YT9217B
Sistema: Android 9.1
DDR: 1GB
Flash: 16G
Al momento de la actualización no hice ninguna copia de seguridad de los archivos de la radio y lamentablemente no se pudo completar la actualización, lo que ocasionó que la radio tuviera una pantalla negra
he estado leyendo el foro y pude realizar la actualización usando el método de punto de prueba con la herramienta flash y descargando los archivos que corresponden a mi radio desde el sitio web de XYAUTO, pero sin éxito. La pantalla negra sigue apareciendo al encender la radio.
Solicito su amable apoyo para que me ayuden a solucionar este problema y me dejen un link para descargar los archivos para mi radio YT9217B o algún método que pueda estar ignorando al momento de recuperarlo.
Estaré muy agradecido por su apoyo.
Adjunto la foto de la información del sistema de mi radio y el video que hasta ahora sigue apareciendo la pantalla negra.

    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 any of these packages you will greatly improve:
    • Stability
    • Speed
    • User Interface
    • Sound tweaking options
    • Customization options


    I wanted to share these all-in-one software packages with you, that I put together using various sources as well as my own modifications for Chinese Android Head units with 1Gb RAM and 16Gb FLASH drive, no physical buttons, models:
    • YT9213AJ (with Audio Chip types: TDA, CSC or SCS)
      Fade not working 8227L YT9213.jpg YT9213AJ_00011_V001_20200421.png

    • YT9216B & YT9217B (same package)

      YT9216B_00002_V004_20200610.png IMG_20210513_234136.png

    • YT9218CH

      YT9218 System Info.png InkedYT9218CH label_LI (1).jpg

    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 Packages contain:

    • YT9213AJ custom firmware
    • YT9216B/YT9217B custom firmware with split-screen option
    • YT9218CH custom firmware
    • ROOT (SuperSU)
    • TWRP Recovery
    • Viper4Android / Viper4A / ViperFX
    • Custom UI (Car Launcher)
    • Custom Boot Animation

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


    !! ALWAYS BACKUP YOUR UNIT BEFORE MAKING ANY CHANGES TO IT !!


    ad pic.png split screen.png EQ.png


    DOWNLOAD #1
    YT9213AJ (with audio chip) supermod package & drivers

    DOWNLOAD #2
    YT9216B & YT9217B supermod package and drivers

    DOWNLOAD #3
    YT9218CH supermod package and drivers



    STEP-BY-STEP GUIDE (upgrading from working stock firmware):
    1. DO NOT SKIP ANY STEPS, AND INSTALL EVERYTHING IN THE CORRECT ORDER. STEPS 5 AND 6 ARE MOST CRITICAL.

    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.

    7. Install the package. Separate instructions are included in every folder of the downloaded zip file. Follow them by the order.

    IF THIS SOFTWARE PACKAGE HAS BRICKED YOUR HEAD UNIT AND YOU HAVE YOUR BACKUP AVAILABLE, follow the steps below:
    1. DO NOT SKIP ANY STEPS, AND INSTALL EVERYTHING IN THE CORRECT ORDER.

    2. It's highly recommended to do these upgrades with your unit connected on your desktop, rather than in the car. Video Guide

    3. Install the Mediatek & ADB drivers on your Windows computer. Video Guide - use the same principle for ADB drivers - (download link is in the video description)

    4. Watch this video on Test Point recovery

    5. Import back your memory dump. 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.

    This post is being frequently updated and you'll find more guides and mods in my signature​
