Could you please provide a link where can i buy a device that will be compatible with your MOD? (2GB ROM) thank you

That's a great question. I want to know that too.
Are there actually any real 2GB RAM devices?

That's not easy as unbranded units aren't standardized. The best way to ensure you're getting the right head unit - is to ask for the System Info screen from the seller. They will normally share it.

2GB RAM is mainly real on 32 GB Flash devices.

I bought a new head unit recently and it was suppose to be a 9217B but in fact the one that arrived is a 2gb ram and 32gb rom 9212B. I was wondering if one of the modded roms were compatible. I saw one earlier comment one user saying he had this unit and the equalizer didn't work because probably didn't have one audio chip. My unit actually have that chip (csc2313s dka6v) and the equalizer works but I have a problem that the audio in the lowest setting is to high and the fact that the original rom sometimes it's slow and some glitches happen. In the attachment i send some pictures of my unit. Thank you for your time and effort.

Now I'm not with the unit connected but tomorrow I can send pictures of rom it self. The rom says it is a 9.1 car edition and in the CPU-Z actually says it's api28.

Here is the pictures I took from the head unit today. It's a bit strange, the kernel in the device appears as version 4.14 but in the cpu-z appears as 3.18 with api level 28. Some of the instabilities are from of the wi-fi signal going down all the time. I'm thinking of installing a wifi antenna. I was wondering if for the bluetooth the same antenna can be used, or should I use another one?

You got a very bad deal. This unit isn't compatible with any of our mods and is also a really scaled down version of an already crappy YT92xxxx device.

I have an xtrons (or rebranded alps) unit. It's an 8227l. Is this mod compatible?

No it's not.

Can i install this ROM? No physical buttons

No you can't. Use our Android 6 MOD instead for your specific model. Link is in our signature.

WELCOME!

I'm sorry about the bad English speech, I'm writing with a translator...

I wonder how this package would work on my device?

Currently android 11 runs, but unfortunately the radio does not work and reacts very slowly. (Belated)

Thank you for your help.

You currently have Android 6. Your head unit isn't compatible with any of our mods.

Can this work for this head unit? It has no physical buttons.

Not compatible. If you bought this unit recently - return it. It's really worst of the worst.

Hello everybody!

Can I install this rom in my unit?

I have been having problmes with bluetooth delay in phonecalls with tis unit and im looking for a firmware to try to solve it.

Best regards

Can't say unless you also share your Kernel version.

How can I upgrade this device?

You can't with any of our mods. Your head unit needs to be upgraded to Android 8 API 27 first, and then you can install the appropriate package.

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

We have a library of preloaders for many of these models. PM us.

Hey, my headunit cant start android after some updates from playstore. It take a while i see the bootscreen and then after 5 minutes im in TWRP. Can i flash dirty with twrp? and can i flash root again with twrp?

You can but full reinstall is recommended.

Hello. I have recently bought an android head unit. I want to know if this mod is applicable on my head unit. I tried to backup my head unit with SP flash tool but my pc doesn't recognize the hu. I am attaching the relevant images

Thank you in advance

It is but if you're unable to make successful backup, it's a good indicator for not try to mess with your unit.

Sometimes you need to connect your head unit to power, 3 seconds after connecting the USB cable for the communication to start. Make sure to follow our instructional video.

Okay I messed up. I tried to do a flash update and now I’ve got the black screen. Nope, no backup file… I know it’s not bricked because Bluetooth still connects and plays audio. Also I get a screen flicker when the reverse camera tried to kick on. Really need some help. I took these photo before hand. Am I SOL? Thanks In advance.

Follow our video and make the backup. After it's made, you can create a "hard reset" firmware. You can flash that firmware (excluding preloader) and restore your unit to factory defaults.

Follow the instructions in the main post. There is a video on how to successfully connect to SP Flash Tools. If it doesn't work for you, try to connect your unit to power 3 seconds after inserting the USB cable and then disconnect from power when any given procedure is done. Do that for every step you insert the USB cable.

Não, não é.



Não, você não pode. Use nosso MOD Android 6 para seu modelo específico. O link está em nossa assinatura.



Você atualmente tem o Android 6. Sua unidade principal não é compatível com nenhum de nossos mods.



Não compatível. Se você comprou esta unidade recentemente - devolva-a. É realmente o pior dos piores.



Não posso dizer a menos que você também compartilhe sua versão do Kernel.



Você não pode com nenhum dos nossos mods. Sua unidade principal precisa ser atualizada para o Android 8 API 27 primeiro e, em seguida, você pode instalar o pacote apropriado.



Temos uma biblioteca de pré-carregadores para muitos desses modelos. PM nós.



Você pode, mas a reinstalação completa é recomendada.



É, mas se você não conseguir fazer backup com sucesso, é um bom indicador para não tentar mexer na sua unidade.

Sometimes you need to connect your head unit to power, 3 seconds after connecting the USB cable for the communication to start. Make sure to follow our instructional video.







You can't use this package as you are on Android 6, not 8. With expert skills it is possible to upgrade to Android 8 API 27 and only after that you can install this mod.

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
  • Customization options
View attachment 5383193

  • 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

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 guide works on the following 1Gb RAM and 2 Gb RAM units with fake Android 10 and Android 11 installed:

- 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.​

    "7. Boot Animation"

    i try copy new bootanimation.zip to root/system/media

    after copy done head unit will go to twrp and run recovery script automatic

    That is because you're triggering a built-in write protection on Android 8. You need to use ADB 'remount' procedure before replacing the bootanimation file. You can find instructions in several of the PDF's included in the package. Start with the one for Viper4Android

    Hiya guys,

    I bought a head unit last year from amazon.

    Details
    Xtrons PSP90CLT Link

    ALPS FF-5000
    ac8227l
    2GB ram
    16gb Rom

    Recently google maps started crashing, after clearing data, uninstalling updates, reinstalling updates the apps works, but when i try to download offline maps it crashes again.

    I had to do a full reset of the head unit to get it to work again. its working as it was before now, but I don't want to go through that hassle again, espeically if i'm away on a trip or very far from a data connection.

    I would like to install this custom rom have working root if possible.

    is this unit compatible with your directions here?

    if you need me to post more screens of any data or relay any more info just ask.

    (edit) I now realized too that reset had caused some issue with the reversing camera, before it worked flawlessly, but now it randomly works randomly shows a black screen.

    Unfortunately none of our mods is compatible with your head unit. I suggest you look at mods for "FF-5000" devices.

    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.

    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.
