Try to connect your unit to power after inserting the USB cable (and repeat for every time you insert the USB cable)

I've tried it too but unfortunately still can't figure out what's wrong?

If your head unit is currently working fine, then it's an issue with the USB cable, USB port on your PC (make sure to use USB 2.0 port) or the drivers.

If your head unit isn't working then it's preloader is corrupt.

Have you tried to disconnect the motherboard from the screen?

Yes this is exactly the problem. You're trying to install Android 6 while you currently have Android 8. It is doable but requires expert skills.

Restore your backup and head on to our Android 8 SuperMOD instead. Link is in our signature.

There is only one and it covers all the YT92xxxx models. Because you probably don't have the necessary audio chip (see original post on YT9213AJ), you won't be able to benefit from all the improvements to the sound. Frankly, the whole mod is built around better sounds rather than anything else so.

hello good people,
i have very bad situation with my android HU and i'm asking for help,
I have podofo 8.1 and it's hard bricked, it's a version 1/16, YT9216BJ ( pictures attached of motherboard) unfortunately I don't have any backup, I tried flash (via SP flash tool) a lot firmwares but unsuccessfully, the best I've ever done is white screen with vertical lines ( pics attached) or just black screen with nothing happened,
my HU is normally recognized from pc and I can flash other firmwares
If anybody has maybe backup or something for my device, I know that android 8.1 is actually android 6, any help or links for working firmware with preloader and scatter are welcome

apologize for long post and bad english

There is a full video on this:
Good morning.
I'm from Brazil and my device is 1din with 7'' screen 1024x600p. (Writed on motherboard is YT9217 ver1.61 and it is different than software printscreen YT9216B)
I bricked my device on July, 2021.

I, inattentively, flash your "boot_1" file and, after this, It was not recognized by "SP Flashtool v5.1824" anymore. So, it turned a brick.
I give up to trying recover on that year.
Here I am again for one more time.

Mate, I don't have tweezers to touch the "Test Point", but I'm using a tin or metal filament. I didn't solder, I just touch the "Test Point" with tin or metal.
Is it enough?

I followed the procedures inside videos made by yourself. (Using windows 11)
By the way, SP Flashtool "format tab" doesn't recognize device.
Installed drivers (I don't know if it's working correctly, because motherboard is not being recognized by laptop).
With only usb connected, Motherboard Blue light is flashing. With DC Car Charger connected it is constant

Does Test point method needs to install ADB drivers?

Did you flash BOOT1 before or after bricking your head unit?

First, on July 2021, I made full memory dump backup with SP_flashtool v5.1824.
After this, I tried to flash MOD, following your tutorial.
But, even not needed, I flashed your boot file and I think it bricked my device, because, after this, It was not recognized anymore.

I was very lazy to disassembly device and use Test Point method.
Now, I made it, but I don't have DC charge adapter. If I need power supply, I need to use car power supply.
My laptop only has USB 3.0 and Type C

    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.

    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!
