[Android Head-Units] ExtremeMOD:
You can but it's not recommended. You will need to connect it only to ignition, not the car battery so that your head unit shuts down completely when you turn off the engine.

This upgrade will take many hours and you will have to start and shut down the engine many times. That's not good for the car...

This is why we recommend doing this on your desktop.
[Android Head-Units] matsam9800:
Ok dear, No worries.

I try to do my best to get this update and if i face any problem I know you are ready to support me.
[Android Head-Units] Penkaty:
Hi, I have a radio like in the picture, will this package be ok? I also have a problem with the sound, the radio works ok, but if I want to listen to YouTube or Bluetooth, there is silence. I read that you have to connect the cables differently, is it true?
[Android Head-Units] ExtremeMOD:
This package will not work on your head unit unless you know how to rollback between different versions of Android operating system.

You currently have Android 8 on your head unit so install our Android 8 package.

As for your sound, if it still doesn't work after you install our software, then it's an issue with your hardware. If it would be an issue with cables, you would get no sound at all.

Are you using the internal amp of your head unit or have you connected through the RCA cables to an aftermarket amplifier?
[Android Head-Units] Penkaty:
So this link https://xdaforums.com/t/guide-andro...rp-custom-ui-brick-recovery-and-more.4318121/ will be ok?

I have internal amp and when i connected blue cable from ant to acc or b+ it be ok with sound
[Android Head-Units] ExtremeMOD:
That is the correct package yes. As for your sound, if you need to connect the blue cable then there is an issue with your head unit.

After installing this super mod on my YT9216BJ do you think I'll be able to circle back and install a ZLINK apk for CarPlay?
[Android Head-Units] ExtremeMOD:
If you intend to use ZLINK and Carplay, do not install this package. In fact, we would recommend to get rid of this head unit all together and get a proper CarPlay unit.
[Android Head-Units] jimiamoore:
Figured you'd say this. Can't tell if it's because you just don't like Apple CarPlay or if it really is a near impossible ask. I already have another cheap Android unit (Alps F9212B) that runs CarPlay via ZLINK really well but I was looking into this for the possibility of having a snappier Android experience when not using CarPlay. At any rate I appreciate all the effort/energy you've put into the custom mods/guides/XDA. It's awesome and much appreciated!

can you help me? my equipment is brick.

android yt9216bj_00012_v001

DDR: 2GB FLASH 32GB

[Android Head-Units] ExtremeMOD:
How did you brick it?
[Android Head-Units] baboski_torino:
I gave a yt9216bj 10in head unit with no physical buttons. Was working fine and attempted to do an upgrade through the app and after it restarted , been stuck on boot loop. It showed android screen, then it says erasing, and restarts.

So j attempted to refresh it. Nothing was working until I did the 2 connect points on board and was able to format it. That's all I have Bern able yo accomplish. It constantly says dram failed. I've tried diverting with drivers, different computers, different combo of external power and etc.

Posting whatever pics I have from when it was working.

Ps: just realized that the board says it's a yt9260 ver 2. But I don't think that would make a difference on the flash tool giving dram error

[Android Head-Units] ExtremeMOD:
You bricked it because you tried to install Android 6 whereas your head unit probably runs Android 8. That's the only reason I can think of

Unless you know how to rollback to 6, you should not attempt this.

Restore your backup and try our Android 8 package instead. The link is in our signature.
[Android Head-Units] baboski_torino:
I was trying to upgrade to newer version. It had 9.1 on it.

The update I was trying to use was, gongban_YT9216CJ_UI-9216BJ_hw-ota-v7.0.zip
[Android Head-Units] baboski_torino:
I'm just seeking some guidance on what to try next.
[Android Head-Units] ExtremeMOD:
If you tried to do an OTA update and it failed, then your unit isn't bricked even if it might look that way.

Assuming you haven't backed it up, you can also restore it using stock firmware package that you can get from the seller and SP Flash tool.
[Android Head-Units] pauloeoe:

[Android Head-Units] baboski_torino:
I was able to auto format using flash tool. But I can't get the flash tool to complete anything else. DRAM error each time. So I'm addimibg since there's no preloader. The stock firmware should have it?
[Android Head-Units] ExtremeMOD:
You don't need the preloader.

Hi all,

i am complete new here :)

I bought an Adnroid 10 API 29 Head Unit, but no sound with internal AMP. If i use a external AMP all is working fine. All Cables are connected correct, but i have to bring it work with internal AMP. Maybe it is a Software issue or something else? Yes have found the option to use internal or external AMP, but nothing more.

Thanks,

Marcel
[Android Head-Units] ExtremeMOD:
This thread is for Android 6 version of YT9216BJ and you are on Android 8.

With that said, sounds like a hardware issue.

i ve try to get root permition with kingo root for pc.

ive recive root permission succcesfully but when i ve tryed to uninstall chrome,

the head unit reboot and reset it self completely.

what to do?
[Android Head-Units] ExtremeMOD:
If you don't run our software, we can't help you.

KingoRoot isn't a real root. Also the Android 8 has a built-in protection against tampering, which is why it resets to factory defaults, as you're trying to modify a system app.

You need to stop doing what you're doing unless you want to end up with a brick
[Android Head-Units] char12:
i want to run it but when i try to reed memory it s notworking...

i ve do all how the video says but no reponse from the head unit

what i have to do?
[Android Head-Units] ExtremeMOD:
Provided your head unit is compatible, try to connect it to power 3 seconds after inserting the USB cable and the disconnect it from power just before taking out the USB cable.

Repeat for every step onwards.
[Android Head-Units] char12:
it's not working also.

when i conectd it to power 3 sec after wiring the usb the head unit swich on but it not read the memory...

is it possoble that its because usb mode is device?

do i have t oput it on host?

what to do ?
[Android Head-Units] ExtremeMOD:
That has no impact as your head unit should be completely disconnected from power during the procedure. If the unit boots when you connect to power then it is not in flash mode.

Start with checking the drivers.

I hope you're doing this on your desktop and not in your car as that won't work
[Android Head-Units] ger8264:
Hello, when following this tutorial on my YT9216BJ device it has fallen into a Bootloop when trying to install the ROM. 😔
[Android Head-Units] ExtremeMOD:
Yes because you're trying to install Android 6 API 23 on your Android 8 API 27 head unit. Restore your backup and install our Android 8 package instead. Link is in our signature.

While it is possible to roll back to Android 6, it's quite complicated and requires expert skills.
[Android Head-Units] Taavi14:
Successfully installed your MOD on YT9216BJ (with buttons). Only difference was that there was no VENDOR selection in SP tool when I downloaded new firmware.

But my HU has another issue that was also present with original firmware. On left side of screen about 5mm is missing or "hidden" behind the edge. Is it possible to somehow adjust the screen so everything would be visible?
[Android Head-Units] ExtremeMOD:
Please share the System Info screenshot. Example is in the first post.
[Android Head-Units] Taavi14:
Here you go.
[Android Head-Units] ExtremeMOD:
I think it's the screen that is larger than the bezel... You could try to get an MCU update from your vendor but it's more likely it's the first.
[Android Head-Units] ExtremeMOD:
None of our mods is compatible with vertical screen units. We are actually looking to develop one so if you would consider donating it, we could use it for development. We'll have it picked up and cover the postage (if you are within EU). Please send us a PM. Thank you

It would be possibel to install this firmware in my Android radio?

Thanks in advance
[Android Head-Units] ExtremeMOD:
It's possible but not recommended.
[Android Head-Units] rafaeliyo92:
Can you recommend any other firmware that is compatible with my radio?

Thanks!
[Android Head-Units] ExtremeMOD:
The only firmware worth recommending is custom-made. Look on XDA as there are plenty of topics on YT9213A

(anyone wants to know what happened before please see the SM8 threat)

So I reflashed my backup back to the device without flashing the preloader. What to do now? Retry with custom FW ?

As my issues concern the SM6 BJ version I will move my request for help there to keep this threat clean
[Android Head-Units] ExtremeMOD:
So is it working? If so, please post your System Info and Kernel version here.
[Android Head-Units] Emilson:
From my experience so far i see that downgrading or upgrading is a bit more advanced process than just uploading same OS version.

Android 6 has a slightly different structure of system partitions than the 8.1, for example it doesn't have a 'vendor' partition, etc etc.

When im downgrading from android8 to android6 Im doing 'format all +download' with complete list of files, so the flashTool will do re-partition memory for android6,

For example here's package im using, its full stock android6 from xyAuto with the appropriate scatter and preloader and full file system (电脑包)9218C_9217C海外UI2-20200706_rmFM2.rar working on my yt9216Bj/9260board.

Then after downgrade I can just flash twrp or supermod6 by 'download only' mode.

When i want to upgrade it i have to do re-partition memory for android 8 again, so im using my backup dump, or lastest packages from xyAuto.

Of course thanks to the author for the whole tutorial wich helped me get it much faster/safer 👍
[Android Head-Units] rndmmeme:
Just flashing back to stock excluding preloader works just fine.

The moment I try downloading the Firmware files from mod (with and without boot.img) it gets stuck in Fastboot. Even after reflashing preloader to it.

These are the photos I took from my device at stock config:

As you can see, kernel is version 3.18.79.

Also I think it's interseting that my device takes the SM8 mod without any issues (except for the being slow part) but straight off rejects any attempt to get SM6 even installed.

I know you're pretty busy but is there a way for faster communication?

If you need any specific information tell me what you need and I shall provide :)
[Android Head-Units] rndmmeme:
I have a yt9216bj model running on fake 9.1.

Are you suggesting to flash an entirely different stockversion before modding?

honestly I'm hesitant to do that as I need to know the correct version. I'm nothing if not curious and I have a solid techincal understanding to even try advanced stuff but i would appreciate some guidance to avoid some trapholes :)
[Android Head-Units] Emilson:
Im not suggesting anything ;D😁

I just said what I did with my unit and what worked, of course Im doing it on my own risk ;P

I already flashed every software from Yt9211/9212/9213/9216/9218/9250/9260/9270 even from other brands like Alps FF-5000 or Junsun.

And everything worked somehow, just some of them have a different sound chipsets, or fm chipsets, or different button/touchscreen configurations.

For example the 'HiFi' release gives me the hifi sound option in 'sound settings' even though I didn't have it in the original 8.1/10.1 version.

so now I'll probably stick to this version.

Ps. Only thing that i suggest you is using AIDA64 instead of using cpu-z. You will see real info about your android system 🙃
[Android Head-Units] rndmmeme:
unfortunatley I can't watch the "android" section in that app, it crashes instantly
[Android Head-Units] Emilson:
my first screenshots of the stock system before any modifications. Specifications look very similar to yours ;)

At that time i was using Device info HW, but doesent matter.
[Android Head-Units] rndmmeme:
So this is my data with the other app recommended by emilson.

As I have 8.1 apparantly, it seems like I can't install 6
[Android Head-Units] Emilson:
👍seems to be exactly the same as mine.

I would give a try my way, downgrading it.

Just take a few more screenshots of 'factory settings' and keep it for you to know your factory configuration.

-Touch settings -> key position

-encoder settings -> encoder reading ways, etc
[Android Head-Units] rndmmeme:
Dude you're a genius, it's actually running Android 6 now!
[Android Head-Units] ExtremeMOD:
You're very welcome. In general, we recommend our Android 6 package as it's simply more stable and actually faster than the Android 8 one.
[Android Head-Units] ExtremeMOD:
You can reach out to us through Facebook or message us on our website. All links are in the signature.

The problem here is that you have Android 6 but your MCU is 4.0 and this is the cause of the problem. Your MCU version is normally seen on the newer Android 8 models. If you can run SM8 - then do just that.
[Android Head-Units] Mac1ne:
Would this package work with my unit?
[Android Head-Units] Emilson:
I would say that it should work, the parameters look appropriate
[Android Head-Units] ExtremeMOD:
It will not work on your unit - at least not without some potential bugs. We highly recommend upgrading your head unit to Android 8 API 27 first and then installing our Android 8 package instead. Changing the operating system requires you to have the Android 8 preloader specific to your model. You can experiment with some of the files found here, just make sure to back up your system when things go wrong (and they will).

If you are located in the UK, we can help you upgrade (free of charge, we are a non-profit project) as well.

Kindly refrain from giving incorrect advice to users, especially on our tools. Thank you
[Android Head-Units] Mac1ne:
I will try to do a firmware upgrade…maybe it will up me to android 8.
[Android Head-Units] ExtremeMOD:
It won't. It's not like the upgrades you do on your Android phone. What will happen is that your head unit won't boot anymore.
[Android Head-Units] Mac1ne:
With the Xyauto upgrade it will brick my unit?

Hiall,

CURSED YT9216BJ

I did everything according to the instructions from the first post:

Downloaded the software, installed the drivers and made a backup with no problems.

during the backup when i insert the usb cable into the android unit the led lights dimly and nothing happens until

I apply power to the unit and then the connection starts without any problems and every step in making the copy has been successfully completed.

the problem started when i started superMOD.

when i flashed the FIRMWARE as per the instructions in the post, after finishing the unit started to reset continuously and wouldn't boot up.

I opened the box and tried to do a test point recovery, but it no longer wanted to communicate with the PC.

When I reconnect the test point, the unit goes to the boot menu and constantly rotates flashboot and recovery on the display, but I cannot select

no option, nor can I communicate with the PC.

it does not respond to volume up and volume down.

attached picture.

I am asking for your help if anyone has had a sketchy experience, because I have been trying to revive it for 3 days and 3 nights, but without success.
[Android Head-Units] ExtremeMOD:
The reason for this issue is that you tried to flash Android 6 API 3 while running Android 8 API 27. This software isn't compatible with your head unit. Use our Android 8 package instead.

If you followed the instructions, then there is no need for Test Point method recovery - it's only the last resort. Right now it sounds like you have corrupted your preloader meaning you got a much bigger problem. You need to completely wipe your head unit and then re-install BOOT1 and then ROM_USER from your backup.

Yes, some units need to be connected to power after the insertion of the USB cable. This will make the TP restoration trickier as you need to do the following procedure:

1. Short the Test Point Pads (do not release) - Connect USB cable - Connect power - Wait for Flash to complete - Release Test Point - Disconnect USB, Disconnect Power

once BOOT1 is successfully loaded, you won't need to use TP anymore. You can find the instructional video in the main post and in our signature (TP Restoration).
[Android Head-Units] Piramida976:
That's exactly what I tried for a couple of days in a row, but without success. it doesn't actually let me do the unit format.
[Android Head-Units] Piramida976:
Looks like I'm in much bigger trouble!

I completely forgot that a couple of months ago I did an update via usb flash from the xyauto site (gongban_9216BJ_hw_12ok-ota-v7.3.7.zip).

Just today I searched my data in the pc and saw that my unit has a totally different android id from the one I posted here.

The interesting thing is that when I bought it it was YT9216BJ and after the upgrade it is YT9216CJ

attached are the data my unit had.

Is there a solution to my problem?

thanks.
[Android Head-Units] ExtremeMOD:
Test Point recovery is the only solution.
[Android Head-Units] Piramida976:

[Android Head-Units] ExtremeMOD:
Yes, you're experiencing a classic boot loop. It seems your preloader is intact (or it wouldn't boot at all). Try to wipe everything BUT the preloader and then flash your ROM_USER file. If that doesn't work, wipe everything including the preloader and follow the Test Point recovery method in the video.
[Android Head-Units] Piramida976:
I followed all the instructions in the video but still without success.

I reinstalled the drivers as instructed and now I get the following warning.

If you have such a problem with the YT9216BJ, you need to use usb port 2 on the unit for formatting
