Ok I flashed the boot and android. Did the factory reset. I see the new UI on the main screen. Is there something I need to flash to fix it lieing in about android saying its android 10.1 ?
[Android Head-Units] ExtremeMOD:
It shouldn't say Android 10 anymore. Something went wrong.
[Android Head-Units] stealthee:
Should I flash everything in the rom folder ? or just those 2. Side question does this update xy auto too ? I did not format and download. I just downloaded it.
[Android Head-Units] stealthee:
I flashed the whole thing with format. and now it looks different says android 9.1 . prob still means android 6 :) but its showing the right memory now too 1/32.

Hi , i bought a new YT9213AJ unit. The gps worked for a day and now shows poor reception.

Do i need new firmware? Has anyone faced this?

​
[Android Head-Units] ExtremeMOD:
It could be

It is Android 6. Actually one can make it say any Android version with a specific hack.

Any idea how to get my Canbus settings back ? I used to be able to do the a/c some amplifier settings AND the factory settings like switching the unit measurements from metric to america and things like when I lock the car the lights would or would not flash. This HU came able to do that. I was kinda shocked. 2012 Dodge Journey. I had to Factory reset it to get the backup camera working. But then I lost the car settings area I used to have. I went into factory settings and did the canbus protocol and set it to Daojun-JCUV . It used to be set to Daojun-JCUV(No CD)-connect but I cannot find that (No CD) Part. Im wondering if they had a special apk installed for factory settings. I dont see anything else other than protocol and ive got that set the best I can. I even restored the original rom back to see if it was in the other xyauto but again dont find any no cd options there. Again I had factory reset the original rom before i backed it up. I know silly me.
[Android Head-Units] ExtremeMOD:
Our firmware does not make any changes to the way canbus works. Sorry.

Hi

I have a very strange problem with unit 9218c

After firmware upgrade via usb, had an error and device rebooted

Now i have dead unit (it powers on, but no boot logo, just blank screen)

I have blue light on mainboard when i connect USB, however device is not recognised by Windows
[Android Head-Units] ExtremeMOD:
The YT9218CH package should have worked. Restore your backup with the Test Point method, as instructed in the video and then try again.
[Android Head-Units] Dragan11080:
Thanks for replying. Unfortunately i have no backup. Is there anything else i can use?

Also sp flashtool does not recognise device connected

What went wrong here?
[Android Head-Units] ExtremeMOD:
In this case you're pretty much done. You'll need an expert to restore your head unit. Sorry but we're not sure how we can make it more clear about the critical importance of backing up your head unit before making system-wide changes to it.

You can hire our services to restore it or any other service provider. Other than that, we can't really help you. Use our website to reach out to the ExtremeMOD team: https://extrememod.co.uk/
[Android Head-Units] Dragan11080:
Off to buy a new unit in the morning then :)
[Android Head-Units] ExtremeMOD:
We would have fixed your head unit for free. ExtremeMOD is a non-profit project. You can PM us to explore some options before buying another unit?

I flashed back to stock rom and the interface seems a bit faster there. Then i just flashed back to your Extreme mod and again im a bit slow. I know you said to try putting my boot.img back in. Did that actually before I flashed back I made a new variant of the my android 9.1 rom from your extreme and called it modified and put my original boot.img back in it. then did a whole format download. and booted up and still slow. slugish. I can hit thinkgs like speedtest and it takes like 7 seconds before it starts to load. Any idea whats slowing it down ?.. so basically took your rom from 0 folder put my boot.img in it. it has the recovery.bin from my finished 9.1 so i have twrp. and then did flash format download.. was i supposed to clear dvac chache after all that ?
[Android Head-Units] ExtremeMOD:
If you follow the guides provided then you won't encounter these issues unless you unit isn't fully compatible (which might be the case). You are supposed to Factory Reset and Cache clear numerous times during the installation procedure. Here are some steps you can try:

Ensure you have a fully working backup

In SP FLash Tools - Format ALL (except bootloader)

Flash you backup back and run FActory Reset after.

Now you have restored your unit to the factory state

Boot the unit 2 times, and on 2nd boot, see how long it take to fully boot (use a timer on your phone)

Now pick the appropriate mod package depending on your unit type and:

Flash Boot.img | Android (or System) .img | Vendor.img (if it's there)

Boot to Android and Factory Reset

Boot the unit 2 times, and on 2nd boot, see how long it take to fully boot (use a timer on your phone)

If boot time is more than 10 secs compared to factory boot, flash your original boot.img back to the unit and after that run Factory Reset. Check the boot time again on 2nd boot.

This is a good start. But if you boot time is slower and the system feels laggy with our mod and your factory boot.img - then the mod isn't fully compatible with your unit type.

I have an issue where my head unit (YT9213AJ) has a parental lock. There is no option to preform a factory reset. I have followed the instructions and successfully flashed your firmware. However there is still no option to preform a factor reset. The previous google account and parental lock remain. I believe I must flash the userdata to fix this. But I am not sure. I have backed up the device as your described.

Should I flash the userdata.img created with Wwr MTK "Collect firmware for a hard reset" or should I flash the userdata.img included in your firmware?

Or is there another way?

EDIT: I flashed the userdata.img created with Wwr MTK "Collect firmware for a hard reset. So far so good. Seems to be running well. Thanks! Looking forward to this new firmware.
[Android Head-Units] ExtremeMOD:
"Hard reset" folder generated by WwR will remove any locks. You've done the procedure correctly.

hey guys i have the YT9217B on stock rom. Anyone knows where i can find the sleep option? So when i turn the car off the radio goes to sleep mode instead of cold booting every single time. I cant find it.
[Android Head-Units] flgmnft:
You should to swap wires battery and ACC.

I have same HU YT9217B, after flash custom rom from this thread, cant run FM APK. I have tried mtcd radio app, but this app dont search FM stations. Does anyone have an application that will work?

OK after factory reset in twrp almost everything goes fine
[Android Head-Units] shurensly95:
Wont swapping the acc and battery wire keep my radio connected like forever? i dont see any timer settings in the radio itself to shut down after x minutes or stay awake for max x minutes
[Android Head-Units] flgmnft:
Check if you have constant 12V on the "battery" cable. and whether you have 12V on the "ACC" cable after turning the key. The radio now behaves as if these wires were reversed.

The Driver package Work with Windows 11 but the Driver is usinged, you must use the unsigned method to install the Driver in Windows 11.

Hey Folks

I was able to preform the Backup & mod on the YT9217B 2GB/32GB Unit, Many Thanks to the ExtremeMod team. All the apps installed correctly and without any issues. The only issue I'm facing is No audio with the music app ( tried several) , The Radio app sound works fine. Any help is appreaciated, ( Video attached)
[Android Head-Units] kobe905:
No Sound issue Update:

The vehicle had an oe amp, which the head unit had to turn on via blue ( ant wire) after the update it would not send a signal to the factory amp but would send if the fm radio app was on, hence the radio had sound and music app did not. ( very weird issue, every worked before the mod )

Solution:

removed the oem amp turn on wire from head unit antenna wire. Reconnected to the red ACC wire ( the amp will turn of when key is on )

FYI: The vehicle installed on is a 2008 Honda Element EX

Hola amigos

Disculpe la traducción al inglés, soy hispanohablante.

Tengo una radio china de modelo: YT9217B

Sistema: Android 9.1

DDR: 1GB

Flash: 16G

Al momento de la actualización no hice ninguna copia de seguridad de los archivos de la radio y lamentablemente no se pudo completar la actualización, lo que ocasionó que la radio tuviera una pantalla negra

he estado leyendo el foro y pude realizar la actualización usando el método de punto de prueba con la herramienta flash y descargando los archivos que corresponden a mi radio desde el sitio web de XYAUTO, pero sin éxito. La pantalla negra sigue apareciendo al encender la radio.

Solicito su amable apoyo para que me ayuden a solucionar este problema y me dejen un link para descargar los archivos para mi radio YT9217B o algún método que pueda estar ignorando al momento de recuperarlo.

Estaré muy agradecido por su apoyo.

Adjunto la foto de la información del sistema de mi radio y el video que hasta ahora sigue apareciendo la pantalla negra.

Mod translation via GT:

Hello friends

Excuse the English translation, I am a Spanish speaker.

I have a Chinese radio of model: YT9217B

System: Android 9.1

DDR: 1GB

Flash: 16G

At the time of the update I did not make any backup of the files of the radio and unfortunately the update could not be completed, which caused the radio to have a black screen

I have been reading the forum and was able to perform the update using the test point method with the flash tool and downloading the files that correspond to my radio from the XYAUTO website, but without success. The black screen keeps appearing when turning on the radio.

I request your kind support to help me solve this problem and leave me a link to download the files for my YT9217B radio or some method that I may be ignoring when recovering it.

I will be very grateful for your support.

I am attaching the photo of my radio system information and the video so far the black screen keeps appearing.

Hi!

I've been planing to flash my head unit for a looong time, but now when I was about to start I saw the upgraded guides. Nice! But something caught my eye: The guides for YT9213AJ mentioned those with the audio processing chip installed. I don't have that. So what should I do now? Will the flashing/mod still work? If not, is there any other solutions? What would you advise me to do from here? ´(I've already upgraded the amp and capacitor). The head unit is a bit too slow for me + the volume increases unevenly.

Best regards! // KvejkarN

Hi, I have a china head unit with 8227L chipset.

I'm confused to determine the android system that is installed on this head unit (see the picture I attached)

My question is what android system is installed, is it the xyauto series?

if so, what series is installed, is it yt9216 or yt9218 or what?

if there are other members who know more about this head unit, please help with the information.

Thank You.

My HU is YT9217B

3.18 . Kernels

Successfully made a full backup

Do as stated in the instructions

The problem is when I try to flash the firmware.

I can't find VENDOR among the 3 to select to check (Boot, Android and vendor).

What do I have to do?

Please give me a hint

I use the default SP flash tools from the download (5. 2036) but it doesn't work.

I changed the version to 5.1824, it still doesn't work
[Android Head-Units] Paid Jo:
So, do you think that when VENDOR is not there, it means we only have to check two parts? BOOTING and ANDROID, am i right?

Edited: yes, post #629 stated like that 😁
[Android Head-Units] Paid Jo:
already managed to install everything, but now have some problems.

1. the sound is too loud, even at level 1 and cannot be linear between level 0 and level 1.

2. Viper can not work with all sound sources. for example the MAPS application. so when we navigate using MAPS with voice guidance and while listening to music, when the navigation application gives voice signals it sounds very loud and different from the sound of MUSIC because the MAPS sound cannot be processed by VIPER. can that be fixed?

3. when I use reverse gear, all sound is muted but not paused, where is the setting so that the sound continues and only the rear camera video appears?

4. when using split screen, every time you click on one of the windows, there is a very annoying pause. for example, when listening to music or playing videos and the other window is another application, surely all sounds will be muted and if the video (youtube) will be paused when I access that window. so split screen doesn't work on its own windows. is that normal? I imagine we can use one window to run on its own and we can access the other one without interrupting the other.
[Android Head-Units] ExtremeMOD:
1. This is an issue with incorrect resistors on the motherboard. A workaround is to reduce the Amp Volume in Factory Settings. If this doesn't work, revert back to original firmware

2. The only source Viper doesn't support is the FM Radio as radio sound comes from a separate onboard circuit. It's highly likely this issue is connected to the issue 1.

3. We haven't modified these settings

4. Could be that your unit struggles with the firmware. Possible solution is to upload the original boot.img and make sure you have only ONE launcher present.

In summary, it sounds like our package is not fully compatible with your head unit.
[Android Head-Units] Paid Jo:
1. I also think that's the case but I've been fiddling with the power amplifier factory settings but no luck, I've even shifted it to level 7 and left-aligned from the standard level 100 (right-aligned) but it doesn't have any effect.

in fact, it's actually unmanageable, it's directly at full level. today I found that at any volume level (between 1 to 30 max) the sound will sound the same because it is already at the maximum level and can't be turned down anymore even though the volume indicator shows the volume is being adjusted.

This happens to all sound sources that VIPER cannot process.

2. I can accept this logic, and I think that's how it should be. but in my headunit it's different. please advise again where should I start for this to work properly. the only reason I'm flashing this is to get a VIPER that can manipulate the crappy sound output of a standard HU. Regardless of what android version I get, it doesn't matter

I think it's just a software problem, should I start flashing everything from your mod file again or just flashing BOOT will fix it?

3. you're right, and don't worry I've found the setting

4. This is also true again. I have more than 1 launcher, and when using the default launcher the problem is not detected.

Worst case scenario, if I go back to the standard version, will I still be able to get VIPER working?

thanks for the reply
[Android Head-Units] ExtremeMOD:
You can revert back to the original firmware and root it manually. Yes.
