En primer lugar, espero que no lo rompa. Si lo hace, puede enviármelo y puedo ver si puedo repararlo. Sin embargo, si vive fuera del Reino Unido, es posible que no valga la pena, ya que los gastos de envío serán demasiado altos. Si no puede restaurarlo, puedo organizar una recogida de la unidad principal y usarla en el laboratorio para pruebas, etc.

Si va a comprar una nueva unidad principal de Android, asegúrese de que sea del tipo YT9216B, YT9217B, YT9218x o cualquier YT9216xxx. Evite YT9213A y YT9213AJ, ya que estas unidades normalmente vienen sin chip de procesamiento de audio. Y, por supuesto, no compre ningún otro tipo. Puedo indicarte algunos vendedores en AliExpress que sé que venden estas unidades.

Espero que vaya bien.

Try to use my video guide instead. It's in the first thread and in my signature.

If that doesn't work, it's a driver issue. Follow my guide on how to install Mediatek drivers and make sure to use the drivers I attached.

Let me know how it goes.

The symptoms are described in detail in my SP Flash Tool guide. I am releasing a full video guide, probably tomorrow, on how to successfully backup and upgrade your head unit.

Thanks for your answer. In fact I have used your video for the test point and my laptop detects the device without problem, just like flash tool. The problem is basically that I don't have a backup to fix the problem, and I'm trying to fix it by searching here on xda.

Okay, please try this package:

YT9213AJ Bootloader Restoration (Android 6)

Remember to install the full firmware package after you have restored your bootloader.

If it doesn't work, describe in detail what you do and what errors you get and we'll troubleshoot further.

I think I need the preloader file for MT8127 but there is no preloader file in the folder. Tried putting in supermod yt9216 file and flash file but it remains black. Is the preloader always the same or does it change?

First you need to recover your head unit. Then simply "Download" the firmware in SP Flash Tool, ticking all the boxes aside from preloader.

I have performed the procedure using test point:
first to recover the bootloader I have installed the scatter file just marking preloader in the format option.

second I have installed the boot1 in advanced mode following your video.

The above steps were done without any errors.

Third, I have installed the firmware by checking all the options in download mode without any error, the result was a black screen.
Did I do something wrong?

When installing the firmware, the Preloader box should not be ticked. Especially if you successfully uploaded BOOT1.

Also, it can take the head unit up to 15 min to boot the first time.

Have you done the full format of your flash by the way? I.e deleting everything including the bootloader, like shown in the video?

I have repeated the process again from the beginning, this time when installing the firmware I have not marked the preloader option.

I have connected the unit and it is on a black screen, according to your indication I will leave it connected for a while, waiting and it works.

About your question, I have followed your video to carry out the whole process.

edit: only the lights turn on but not the screen.

    Ok I'll try.
    The guide to use would be this?

    Or should I just use the scatter file?

    Here's the video I just uploaded. It should help.

    What do you mean by "fade will not work" for the unit without the audio chip? If the unit doesn't have the audio chip this mod will not work? Thanks.

    It means that if you have the newer generation YT9213AJ (applies to YT9216BJ as well) you won't have ability to manipulate sound by means of EQ and Fading/balancing sound between the speakers.

    The mod might work but it hasn't been tested on units without the audio processing microchip

    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.

    Thank you for your feedback guys. Unfortunately I don't have this unit so I cannot test the memory dump but last time I imported it, everything worked. There might be a number of reasons for the issues you are experiencing and so I've added TWRP, ViperFx, custom Boot Logo and Custom Interface files to the original post so you can manually install them. The good thing is, is that it is super easy and all of these files are optimized for YT9213AJ.

    I have used two days trying to get this working. I guess you need to press ctrl+alt+v in SP flash (advanced mode) for the write memory option. But I can not figure out how to apply hex size from the memory map txt file included in the download. Presumably the memorymap contains the size of the partitions, but SP Flash write mode ask for begin address...?
    Im also wondering why recovery partition does not seem to be included. Is TWRP not installed in the recovery partition?
    Included scatterfile from MT3367 ?

    No worries, I have updated the original post with a full guide on how to import this memory dump. Check it out.

    Your mod got me thinking could I do it with the later firmware, it was a mission but it's done, Latest API 27 v6.5 true android 8.1 with working ViPERFX instructions and download here https://forum.xda-developers.com/t/...d-8-1-2020-root-and-viper4android-fx.4205037/
