You could get your own backup just in case.
Btw XYAUTO, there are usually two packages on the xyauto website, one is for update thru 'android upgrade' in 'car setting'. the second one is for manually flashing update thru SpFlashTool. You could try the first 'android upgrade' option.

You can find useful info about backup, etc. on the first page of this thread or from these links:
- collection-of-8227l-firmware-android-vers-6-9

- rom-firmware-brick-recovery-for-7-android-head-unit-ac8227l-yt9217-yt9218-1-16gb - and i suggest you to direct your future questions to the thread from this link.
Because this thread here is only about Supermod8 modyfications

Hi,

Many thanks for making this detailed guide.

Spent all evening doing the backup, creating my own cluster file and installing the firmware

In the end got faced with a boot loop. I hope my HU is compatible. I have already restored it so everything is working fine just when I try install the new firmware it gets into a boot loop.

I will attach a picture of the HU info.

Bună, am o unitate cu Android 11 (nu cred), cu versiunea F9212B_AHD_00020_V001, XY AUTO:F7.0(X2) DISPLAY 1024X600, MCU:4.2(X2) DDR:2GB ȘI FLASH:32GB, este dedicat pentru Ford C-Max 2008, și nu funcționează foarte bine, și văd pe site-ul XYAuto un firmware nou 7.3.7, dar este Android 10, și încerc să actualizez sau poate să fac downgrade :) știi dacă este corect sau nu?
De fapt, nu pot vedea toate opțiunile din canbus-ul mașinii mele, cum ar fi senzorii de climatizare sau de parcare, toate originalele din fabricație.
TKS in advance,Cosmin.

This is not the right thread for you. We are only focusing on the ExtremeMOD firmware and tools, not factory configurations. Please create your own thread

Oh I didn’t see this, thank you for the info but it seems the model is different does it matter? I have seen one even YT9216B when mine is YT916BF.

Those two models are very different. Even YT9216B can be different from another YT9216B, thanks to the "intricacies" of Chinese manufacturers. Again, you need at the very least have your backup ready before starting to experiment.

@Emilson seems to know his way around this, so perhaps consult with him/her privately on the procedure of upgrading from 6 to 8.

Everything is backed up and I can restore without any issues

I will wait and see what he/she says before I pm

Thank you

The sound mod requires changing additional capacitors (the ones connected just before your speaker output pins on the TDA7850. They are 100 nf (4 of them) and you need 2.5 uf.


Then you need to properly configure Viper4Android to hear difference.

Make sure to have active cooling on your TDA7850 (heatsink with temperature-controlled fan) or your unit will burn up.
where are 100 nf capacitors located on the board that need to be changed to 2.5 uf?

Hi, I'm new to the forum I'm looking for if my Android radio YT9213AJ works apple car play and I find absolutely nothing, in other forums including this one talk about an application called "Zlink" and "Tlink" of which I could download "Zlink" and I get the message that it is not possible to install it. My radio has root with viper sound. In short I want to know if for the model of my radio there is the possibility of using CarPlay either remote or wired please thank you in advance for your answers.

Hi Gerper, unfortunately, this isn't the right thread for you, as it is only about our custom firmware.

In general, no Android Head Units works properly with Apple products, ZLink, Carplay and similar apps included. If you plan to mostly use your head unit with your iPhone - invest in a proper CarPlay head unit from one of the big brands like Sony or Alpine.

Your head unit has no audio chip, so Viper will have no effect and you have probably already noticed the poor sound quality.

    i have "android 9.0p" install and is very buggy.it's possible to stock android 8
    and whih one.

    can you help me?

    Your Android is already version 8. Our software should be compatible. Make sure to make full backup and follow the instructions to the letter.

    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
    • Customisation options

    • 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

    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.

    This firmware works on the following 1Gb RAM and 2 Gb RAM units with fake Android 8.1, 9.0, 9.1, 10 and Android 11 installed, with screen resolution of 1024x600 px. It will not work on Tesla-style units:

    - YT9216BF | YT9216CFJ | YT9216BJ | YT9216BFJ | YT9216CJ

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

    The zip file package contains:
    • Modified firmware - courtesy of Stranger21UFA @ 4PDA (link to the original post)
    • TWRP (separate folders for 1GB and 2GB RAM units)
    • Root via Magisk
    • Viper4Android
    • Car Launcher
    • Boot Animation
    • SEPARATE INSTRUCTIONS ARE INCLUDED IN EVERY FOLDER

    >>>> ALWAYS BACKUP YOUR UNIT BEFORE MAKING ANY CHANGES TO IT <<<<

    !! IMPORTANT !!

    This is a fairly advanced installation process and will require you to follow the individual guides included in the software package - to the letter. Failing to do so, will (in "best" case) result in a slow and buggy head unit and in the worse case - brick it altogether.​

    Below post is to show my respect & appreciation to iceblue1980 and in addition to share my experience that had for a few days while trying to make my unit better with above firmware.

    As I downloaded firmware package, I chose not to follow his guide by letter & skip a few steps, for example & most important, not to take full back up of memory.
    Then disaster followed, as I almost bricked the unit.
    So I turned back to post/s to find solutions. Iceblue1980 was there, day & night responding to me & sending me several alternatives to try.
    He even volunteered to fix my unit by sending it to him without any money even if he had to spend valuable time for it.
    Finally, after several attempts & lots of files / firmwares / guides he sent me the gold package & we made it work !!!

    I carefully followed his last guide by letter & that was it.

    Now my unit is back to life & even better than ever.

    This guy is awesome & I personally thank him so much.

    To all members, PLS FOLLOW author's
    guides BY LETTER EVERYTIME to avoid surprises !!!!
    AND
    Don't forget to thank the people who are there for you day or night.
    They use lot of their personal time to be there for you & that is priceless !!

    :) :) :) :)

    The links go to a '404' page.
    I did the first step as per the guide then did a factory reset. I then installed TWRP and rebooted then unit. Then I ran the 'reboot recovery' command in the terminal emulator and the unit rebooted, but it only shows the logo, some vertical lines on the bottom half of the screen, then a black screen and hangs there.

    I can still reboot normally and the unit will run.

    Separately, when resuming audio tracks after key-off, the audio is very choppy and unusable. Both bluetooth audio and the music app behave the same.

    To recover, I have to reset the unit and then the audio is ok.

    Also there's a very loud audio boom on start up and shutdown of the unit. This is not there in the stock firmware.View attachment 5409085

    Thank you for sharing these details. I'm afraid your head unit is not compatible with any of my software packages. If you haven't done so already, please revert back to factory firmware to avoid issues.

    These are the recovery test points:

    The Wifi/BT antenna mod is shown here, however I plan to post a proper guide on this particular mod in the future.

    The method I had to use slightly differs from everything I have read.

    1.) I wired a toggle switch to my positive lead. Left it in the off position (no power to head unit)

    You could share a picture of your soldered button. Some folks here might find it helpful :)

    I'm thinking of making a guide going for a permanent mod, where the soldered tactile SMD button will be accessible through a small hole in the back of the head unit (similar to how you access the RESET button). That way you can use a 'needle' to short the test points, rather than picking the unit apart every time.
