[Android Head-Units] septicide:
Well after sucessfully following your tutorial with it running 100% then bricking my device upgrading to v6.5 (anybody else trying that after this mod dont use the stock preloader) then ripping her apart to do some xbox 360 modding on the test points and flashing/unbricking can safely say if it aint broke leave it the hell alone! Nice job guys you saved my a%#. Ive attached a switch to the back of my unit for future mistakes
[Android Head-Units] septicide:
Oh and if anybody is having trouble with flashtool not detecting with only usb power you may need to run dc power
[Android Head-Units] septicide:
One question man, since the device is uncertified by google the app store doesn't update, it's android 6.0 right so the latest variant of opengapps should work on this through twrp? I'm also having a play with merging the latest updates from xy auto, namely the CAN update onto this as it's impossible (for me) to get the twrp recovery loaded on the new firmware without bricking it ... *update* that was a stupid question it's android 8.1 go edition so no opengapps support just download latest google play store apk and download apps needed
[Android Head-Units] septicide:
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://xdaforums.com/t/yt9213aj-la...d-8-1-2020-root-and-viper4android-fx.4205037/
[Android Head-Units] Gunash:
I sucsesfully installed dump rom and device boot up normally but there is not twrp recovert and v4a and root access! Then try to add them manually and first start with twrp but when i hit download and connect device i have this Tpm changed for the rom it must be downloaded! What can i do to solve this and install recovert and root and v4a ?
[Android Head-Units] septicide:
You have to manually flash twrp afterwards, instructions are on the 2020 update on the first page.
[Android Head-Units] Gunash:
Thanks i manually install twrp and then try to install root and v4a butafter installing sucsesfull and boot up device there is not v4a installed in mu device ! Is there any other version or something of v4a to try installing via twrp ? Help me to solve this please.
[Android Head-Units] ExtremeMOD:
There is an installation guide in the zip file. I suggest you check it.

V4A, ViperFX and Viper4Android refer to the same app. In order to make this app work, you need to have couple of other apps installed in addition to root.

I also suggest you check instructions on how to use Viper4Android as it is quite vast.
[Android Head-Units] Gunash:
Thanks . i also have another question how can i boost start up time when i turn the car on and of it takes time to power up android ! Or is there any way to allways on the device and power of just when needed and not when the car is on and off ?
[Android Head-Units] septicide:
That's the fastest you are going to get for boot up time, the api 27 firmware I put up is slower than this, in regards to the power, hook both the batt+ and ignition wires up together to just the battery but put a switch in the dash somewhere and attach to the ignition wire through that so you can have control away from the ignition switch.
[Android Head-Units] cheesmountain:
What kind of material is that where the TDA7850 comes in?
[Android Head-Units] ExtremeMOD:
We can repair it for you if you wish to send it to the United Kingdom. Alternatively, find a similar repair shop near you
[Android Head-Units] Brainfarth:
The UI is so painful. My immediate goal is to run Android Auto so I can plug in my phone and do what I know. My later goals are custom everything. So I need a root and image that plays well with this unit. Can someone help me on my journey?
[Android Head-Units] ARTHASLF:
good morning friends attached photo of my board of my radio yt9213aj board model t9260 v1.2 but I notice that it is not the same board that they posted here to update the dsp chip. If you have the schematic and the location of the components for this board, I would appreciate it. Thank you so much.
[Android Head-Units] ExtremeMOD:
You should invest into an Android Auto unit, if this is your main area of use. A full-on Android will do everything AA does, including all phone functionality. Our ExtremeMOD head units are deliberately blocked form using Android Auto and CarPlay
[Android Head-Units] Brainfarth:
Your mod sounds like what I need then. Is there an issue if mine reads T9812B and not YT9812B?
[Android Head-Units] ExtremeMOD:
What it 'reads', doesn't always correlate to what's inside, it's a general direction. Here is an example of one of the ExtremeMOD Android head units built from an XYAUTO YT92:

You have to look at the motherboard itself.

In any case, if you don't skip the backup procedure then worse case, if the mod doesn't work - simply restore your backup.

Your motherboard should have these microchips as the bare minimum:

.....

And look very similar to this motherboard in terms of layout:

Good luck!
[Android Head-Units] Brainfarth:
My recovery at step 2 has failed for the second time.

I'm not totally hurt about $130 down the drain, so I was wondering what unit you would recommend? I dont mind spending a little to find something that's flexible and smooth.
[Android Head-Units] ExtremeMOD:
Your head unit isn't compatible with any of our mods.

We can try recover it for you in our workshop. We're located in the UK. Send us a PM for details.

The repair is free but we do welcome donations.
[Android Head-Units] B0SN1AN:
Hello ExtremeMOD.

I have the model from the picture without physical buttons. Everything works fine for me except the microphone, because the person I'm talking to can't hear me very well and the FM radio doesn't receive the stations very well. Will I improve with this if I install and can this work on my model? Thanks a lot.
[Android Head-Units] ExtremeMOD:
Unfortunately it will not, but you can improve the radio and mic audio in the Factory Settings (pw: 8888). You can find a lot of info here on XDA on how to do that.
[Android Head-Units] B0SN1AN:
This is my device inside and I believe it doesn't have a radio chip. I looked at your pictures from the beginning of the post and in yours I see that there is a chip in this place, but not on my device. I don't think I can fix the signal for FM, because I tried with the FM amplifier and I didn't get a better signal. I don't think I can help him :) Thank you very much for your reply and for the very helpful post.
[Android Head-Units] ExtremeMOD:
Yes, your model does not have the NXP chip which delivers HD Radio. But it can be installed.
[Android Head-Units] B0SN1AN:
Is the one I could install the same as yours from picture above? Should I search by number from yours?

I can't clearly read the letters on the radio chip from your picture. May I ask if you have a clearer picture of the chip somewhere?

Thx.
[Android Head-Units] ExtremeMOD:
Here is the product link. As well as the datasheet. Bear in mind that you need to add all the surrounding components (resistors etc) for it to work

MOD TRANSLATION

"Good evening what reading 😅

An Android car radio to buy on a Chinese site 😣

In short it works not terrible I change all that if it is possible to free everything and have a new Rom??!

At worst just an .apk to change the radio application which I find lame and which would work with the antenna without an internet connection.

If not to flash the rome if it were possible to do it quickly without dismantling the car radio that would be preferable thank you for answering me and congratulations for your work

I am looking for a NavrRadio compatible car radio application does not work internet radio just with car antenna"

Bonsoir que de lecture😅

Un autoradio Android acheter sur un site chinois😣

Bref ça marche pas terrible j'change tout ça s'il est possible de tout libérer et d'avoir une nouvelle Rom ??!

Au pire juste un .apk pour changer l'application radio que je trouve naze et qui fonctionnerait avec l'antenne sans connexion internet.

Sinon pour flasher la rome s'il était possible de le faire rapidement sans démonter l'autoradio cela serait préférable merci de me répondre et bravo pour votre travail

Je Cherche une application radio compatible voiture NavrRadio ne fonctionne pas de radio internet juste avec antenne de l'automobile

How can I downgrade the system? I'm on android 10 and it sucks
[Android Head-Units] ExtremeMOD:
It's already Android 8 API 27. Our firmware package 'officially' supports MCU 4.1 and below. We haven't tested nor can recommend installing it with higher version of MCU.

Good afternoon, fellow forum members, while browsing the 4PDA forum I have found information about the installation of the tda7729 audio processor and the chip for audio improvement. It would apply for yt9260 v1.1 board. If someone from the forum could verify this information.

[Android Head-Units] mark-1978:
got a bootloop. So i had to reinstall everything, but i found a smarta** way to install viper4android. So, you flash the magisk converted boot.img, and then you install magisk apk. Then you have a rooted device. Now you use magisk app to install the v4a zip file. Reboot. Install the v4a apk. Turn on legacy mode. Voila v4a installed.

Salve a tutti

Da qualche tempo cerco un nuovo aggiornamento per la mia aturadio yt9213aj

purtroppo anche dal sito non riesco a trovare il firmware appropriato

ovvero cè, ma al momento di installarlo dopo che arriva a circa il 30 % di installazione mi

da errore e si blocca, ripartendo nuovamente e ricaricando lo stesso firmware che ho

in questo momento, il quale manca di molte app ed come stabilità lascia

a desiderare.

Premetto che non sono uno specialista in merito

ma se qualcuno potrebbe aiutarmi magari postanto in italiano un guida di come

fare passo passo, ne sarei veramente grato.

Perfavore aiutatemi, altrimenti questa radio non fa altro che prendere polvere

ed la dovrei utilizzare come fermacarte, un peccato veramente.

Se poi qualcuno mi posta un firware che possa aggiornare tramite usb

ne sare veramente grato.

Grazie a tutti veramente.

GRAZIE....

@ExtremeMOD I have just bought a second hand vehicle with the below Head Unit.

YT9213AJ​

I joined the forums as you guys seem like you know this system inside and out so I am wondering if there are any recommended further flashes I should try since the original post on this thread way back in 2020? Or maybe it's as good as it will ever get rn on 9.1?

On the picture attached, it shows that is is currently on Android 9.1 Car edition. Apologies for the chopped off text but you can still see model, version etc.

If there's a more recent post with latest versions etc, I apologise. Any help pointing me in the right direction or any advice or links you have are greatly appreciated.

I include Kernel/version etc in the images, hopefully I have posted everything you need

Cheers.

Hi there, I've come across this thread, and got one of these stereos for about $25. It's okay so far, but I'm hoping I can use your software to make it even better.

It is a YT9213AJ, MCU 3.1, and Kernel 3.18.22

Images are enclosed for your review as well, and thanks very much for this thread, and your help!

[Android Head-Units] hqdmx2:
Give it a go. I have same unit and was able to do this mod. You will however have to connect power to unit everytime you go to use spflashtools. I found this out searching the forum.
[Android Head-Units] chosenone1:
can anyone please confirm. I want to start the upgrade process today
[Android Head-Units] hqdmx2:
Hey guys, I hope to get alil help. Maybe I'm not looking info on this up correctly. I did this whole process on 2 units. It all takes fine but as soon as I try to use link2sd for almost anything, both units reset as if I do a factory reset. Everything else seems to work fine. What am I doing wrong or how can I prevent the resets? TIA
[Android Head-Units] #40Fan:
If anyone figures out how to get the speed shown on the main screen changed from Kph to Mph, let me know.

I'm not using any of the Car Launcher or Viper part of this process because it caused the radio to wig out, if that makes any difference.
[Android Head-Units] chosenone1:
Hi @ExtremeMOD , following the process, I have installed drivers but when running memory test in sp flash tool nothing is detected. tried two cables as well as PCs. What am I missing?
[Android Head-Units] #40Fan:
You likely need to power on the radio 3 seconds after connecting the USB.

Hi, just got a new car with an Android Head Unit. Can @ExtremeMOD tell me if one of his mods work, its not clear to me because there are so many versions of it out there. I think i have a XYAuto yt9213aj WITHOUT a DSP chip, but i would be able to solder one if this changes things. I asume i have no Chip, because Fade does not Work for me. Also my Unit got an update to "Android 10" so i dont know if this one or the android 8 version would work for me. I post the Specs, hope you can help, and tell me what i have to do to use one of your mods.

just wanna say that this works great. installed it last year

rooted. viper driver is really nice. it doesn't work on Spotify though. but coverall, quite speedy and low on resources. I use nova launcher, waze and poweramp and it flies.

Thanks for the hard work.!!
[Android Head-Units] vladvlad12:
Man, thanks for your efforts to develop this, will try I think later today to install, will follow the guide and make a backup before, will let you guys now later how it went.

Thanks!

Edit: Can this be done with unit connected to car, and laptop connected to the USB port that it has?

Edit2: Just orderd an DC adapter and connector, will arrive tommorow probably.

Should it work with my navigation YT9218C not CH? Photos bellow ExtremeMOD
[Android Head-Units] arthur61:
Hello, please share if it is suitable for this device. If it is not suitable, can you share one that is suitable? Only the menu icon is very bad on my device
[Android Head-Units] arthur61:
Is there a USB version of this?
[Android Head-Units] vladvlad12:
Yep, it works!
[Android Head-Units] vladvlad12:
Was a bit slow for me cause I needed to order the power source and the iso socket for power.

After that I had an issue cause my usb was on the other port, the one with the 6 pins(but only 4 wires)... Needed to adjust it to fit in the 4 pins one.

After that everything worked smooth following the guides. Did not use the root method in the guide, and used magisk instead. Still it works.

Strange issue now, if my navigation is off, the laptop detects it as COM but If I power it on it does not detect it ( I was thinking maybe some driver issue) but then took the navigation back in the car where I have a front camera ( a simple camera with a SD card in it with the apk needed for it - XDR or something chinese, don't remember the exact name).

But still the camera won't connect via USB to the navigation. Anyone had a similar issue?

Tried both ports 6 one and 4 ones( this was used to flash navigation) still camera won't work.

In my country the camera is really a good thing to have, as we have many id10ts driving here...

At this step

I did not have the VENDOR, so chosed SYSTEM and ANDROID, can this cause this issue?

Hmm, seems like somehow I managed to fkc my usb, it gives no power, but using a 4 port usb switch, I get the power from an car charger to the switch, then from switch in the navigation, and in the camera, and it works
[Android Head-Units] vladvlad12:
Maybe try that thing with the Point test on motherboard, but if you do not have a backup of the unit it may be hard to recover. Maybe try and find the scatter file for your exact navigation and try with that to recover it.

I just installed yesterday this soft on my YT9218C and work pretty good.
[Android Head-Units] Gunash:
Also yesterday i installed v4a following your instruction but after installing v4a and open it up and try to install driver after dialog shows device restarts and lock in boot loop ! Waht can i do now in this situation ! Installing the whole rom again ?! 😢
[Android Head-Units] ExtremeMOD:
Faster? The unit starts in a couple of seconds when you start the car, provided you connected it correctly.
[Android Head-Units] ExtremeMOD:
Sorry to hear that. Viper4Android cannot cause bootloop by itself afaik so it must be something else.

Did you wipe the cache in TWRP after installing the mod?
[Android Head-Units] Gunash:
Yes i did but there is not chance to bootup device ! What do you suggest to do for me now ?
[Android Head-Units] Gunash:
If you mean 30 or 40 sec as couple of secounds yes its not fast . what can i find exact connecting how to ?!
[Android Head-Units] jpa66666:
Just wanted to say I used this today to flash my "Liehuzhekeji" brand radio that I got off Amazon for $80

Only issue was flashtool wouldn't work set to 0x0 had to type out 0x0000000000000000

Also had to flash the files via your second post for recovery and root ECT ECT. But now I have my unit working correctly with viper4android as well as wireless android auto via headunit reloaded. Thanks!
[Android Head-Units] ExtremeMOD:
No, I mean like 3-5 seconds. Only cold start takes about a minute. If you connected it properly, your head unit will not fully shut down when you turn off the car ignition, it goes into sleep mode instead, hence the quick startup time.

To your bootloop problem, just restore your unit to factory default. You can follow the procedure in OP to successfully import your backup.
[Android Head-Units] Gunash:
Unfortunately i do not have the how to manual for this device and i do not know exactly how to instal the wires to work as you sayed can you orovide me with manual or somthing to i know how to install this model? And also i want to reinstall theirst post of this topics rom and also v4a hope do not run in bokt loop after install8ng v4a driver again !
