Thanks, that's really comforting.. But on the bright side - you're in luck! I have just received a broken unit that has exactly the same motherboard as you.

We can give this another shot as B9216 motherboard is slightly different from the "standard" XYAuto editions. If all goes well, I'll be able to create a SuperMOD package for this particular motherboard and head unit edition.

I'll PM you.
[Android Head-Units] lumberjakk_89:
What do you mean by "fade will not work" for the unit without the audio chip? If the unit doesn't have the audio chip this mod will not work? Thanks.
[Android Head-Units] ExtremeMOD:
It means that if you have the newer generation YT9213AJ (applies to YT9216BJ as well) you won't have ability to manipulate sound by means of EQ and Fading/balancing sound between the speakers.

The mod might work but it hasn't been tested on units without the audio processing microchip

Unfortunately that guy never came back to us so we don't have it yet.

!! ALWAYS BACKUP YOUR UNIT BEFORE MAKING ANY CHANGES TO IT !!​

and

** IF YOU ARE UNABLE TO RESTORE YOUR UNIT, PLEASE CONSIDER DONATING IT TO ME, SO I CAN BUILD MORE MODS AND TUTORIALS​

So, I think it's compatible, right?

Hello there. I have a Seicane 9 inch Android headunit. Would like to double check if this ROM is compatible with it? Also, is it possible to install this while the headunit is in the car, but just removing the battery connection under the hood so that the only connection will be the USB at the back connected to the laptop. Many Thanks! Here are the pictures you asked for in your post. Regards!
[Android Head-Units] XamHiangGuai:
Is my headunit compatible with your ROM. Thanks!

Do you Know any Firmware to update my Unit?

I don't find them!

Thank you very much!
[Android Head-Units] afarkas:
This is all i can get from it

Thank you
[Android Head-Units] ExtremeMOD:
Yes, there are firmware upgrade packages for this unit type out there and while we have access to all of them, we can't safely recommend anything without having this unit physically in our workshop. Chances are, if you attempt anything, you will brick your head unit beyond repair.

You could try to run full Factory Reset and see if that fixes your issues?
[Android Head-Units] ExtremeMOD:
Your head unit is not compatible with any of our packages.
[Android Head-Units] afarkas:
oh. thats pity... dont you know about any other i can try? I did not found
[Android Head-Units] ExtremeMOD:
It doesn't look like any of the head units we know.

The vendor just provided me with the system package for reflashing my device. Would you like me to provide it so you can eventually develope it further fo my type of devices?
[Android Head-Units] ExtremeMOD:
Thank you for your kind offer. Please share the package but first install it on your head unit and see how it works :)
[Android Head-Units] afarkas:
well, i just realised i can not install... when in settings i click Local update, it does not see the package on the usb drive... it says "please insert sd card or usb"...

The reason i asked the vendor for update package is that i rooted my device not properly and now it resets itself when attempting to access anything in /system...

also, when attempting adb shell mount -o remount,rw /system it just resets itself to factory defaults (and reboots)

system update does not work anymore...

the su is present in bin and xbin as well

is there a way to push it via adb, or flashtool?

mine is working, but not properly...

also, im unable to boot to recovery or fastboot... not even by adb command...

Can't tell as we don't know anything about this head unit and this thread is about YT92x x head units.
[Android Head-Units] afarkas:
I understand. Just one more question, to make everything crystal clear.

Are you saying that your ROM will not work on my device for sure, or are you saying it probably will not, but may be it will?

you were right, sir

the autoupdate folder had to be in the root of the usb

but i cant root the device anyways...

Firstly, thank you,

I'm not sure if I can do this I wonder if my system is compatible with it,

I'm using translation and my english is a bit bad sorry

[Android Head-Units] afarkas:
HI again. I managed to get my HU into flashmode, so i can start memory test and backup BOOT1 ... however, when trying to backup ROM_USER the pulling process interrupts as the radio boots up after 15 minutes...

(the only way to get it into flashmode is to start ReadBack, then connect the usb and then connect the power)

Any suggestion how to prevent the radio boot up after 15 minutes in order to finish the readback?

Thanks
[Android Head-Units] ExtremeMOD:
That's a tad strange phenomenon. Is the motherboard completely disconnected from everything including the screen when you attempt this? Normally you shouldn't need to connect it to power during this operation. You could also try to disconnect it from power about 5 min into backup of User_ROM.
[Android Head-Units] afarkas:
No, the motherboard isnt disconnected, only tje connectors are all empty
[Android Head-Units] ExtremeMOD:
And there's your answer. Please follow the video instructions closely.
[Android Head-Units] afarkas:
Well, so i made some tests...

Even with display disconnected, the HU WONT start in flashmode after connecting the USB...

Even with display disconnected, the HU WILL start in flashmode after connecting the power...

Disconnecting the power after 5 minutes disrupts the readback process - both - with or withouth display connected...

And both - with or without display connected - the HU will boot up to normal mode after being 15 minites in flashmode...
[Android Head-Units] ExtremeMOD:
That's a strange problem. Okay, please post high resolution photos of you motherboard, including a clear picture of the motherboard version and the label inside the big white connector. Also take picture of the back and front of your head unit.
[Android Head-Units] ExtremeMOD:
Okay I see what the problem is. Your head unit isn't compatible.

Check the pictures in the OP, you'll see what a compatible motherboard should look like
[Android Head-Units] afarkas:
Well, yes, sir, we knew that already a month ago my HW is not compatible with your SW... And im not trying to install your SW... Im trying to make that damner Readback and then find a way to modify my files to flash root or twrp into it...

Anyways, thank you
[Android Head-Units] ExtremeMOD:
There might be some security mechanism on your flash drive. Or your FRP isn't unlocked. Other than that, can't really help you.
[Android Head-Units] afarkas:
Sorry, sir, what FRP stands for?
[Android Head-Units] ExtremeMOD:
Factory Reset Protection. Means you can't upload any firmware by standard means. You need to remove the lock first. Don't ask me how however, as I'm unfamiliar with your head unit type.
[Android Head-Units] afarkas:
OK. And hypotetically, this lock can cause the protection to be open less than 15 minutes and then close?

Im asking, cuz the Readback works fine under 15 mins. The BOOT1 i successfully obyained, as it was a few seconds job... But the ROM_USER reached 5,08GB and then the connection failed as the device booted into normal mode.

I also tested and can confirm that what matters is the time (15 minutes) and not the ammount of data downloaded, as i have try on slower laptop and faoled at 15mins, but less data dovnloaded (4,7GB)...

So... Can the lock be open for some time and then close?
[Android Head-Units] ExtremeMOD:
The lock would activate after a fixed amount of time to prevent firmware upload.
[Android Head-Units] jordantheripper:
Hi peole. I'm reading the guide but I'm not so sure if I can upload mod firmware on this my unit.

Can You hel me? thnks from Italy
[Android Head-Units] ExtremeMOD:
No, this mod isn't compatible with your head unit. The Android 8 mod is however.
[Android Head-Units] jrigga39:
hello, I seemed to have bricked my hu. Everything went through without error, I followed the backup procedure to the letter. But ive had no luck getting the oem rom back on. Im attaching a snap shot of my kernel. Can you verify that my unit is useable with this software, and if so which one. I had the fake 9.1 on here originally. thanks in advance.
[Android Head-Units] ExtremeMOD:
Sorry to hear that. Do you have a picture of your System Info?

1. Describe exactly what is happening to your head unit when you try to boot.

2. Describe at what stage during the package installation it got bricked.

3. Did you manage to restore your backup successfully before installing the mod?

4. Why can't you restore your backup? The computer doesn't detect the head unit? Have you tried the Test Point restoration method?

This should be a good start. If possible, attach picture of your motherboard back and front as well as the label on the big white connector (as shown for YT9218CH in the original post).
[Android Head-Units] jrigga39:
I thought i had taken a pic of my system info, but I guess i didnt.

when i power it, up buttons lightup, and the screen lights up like its about to boot, but never does. then the screen becomes darker again, this cycle repeats about every 30 secs.

I actually didnt try the backups before. Im not sure why the backups dont restore, I dont get any errors and everything seems to work.

I havent tried to open up the unit yet or do the test point method yet, was going to try that next, just thought i would see if there was something else i was missing or make double shure my kernel was right. I actually thought i had the yt9216bf??
[Android Head-Units] ExtremeMOD:
In the instructions it clearly states to first backup and then to restore your backup, before doing the mod.

You head unit isn't bricked. It's in a bootloop. You need to restore your backup as per the video instructions. Also YT9216BF is likely to have come with Android 8 not Android 6, which would be the main reason for why this package didn't work. Once you have restored your head unit, try our Android 8 package instead.
[Android Head-Units] jrigga39:
Yes it is 8.1 saying 9.1 i actually had tried the 8.1 package first. The reason i didnt test out my backups is, i have about 4 of these units that the chinese company has sent me. Everytime i had an issue or question they would just send me another one..lol. ill try to restore the backup again. I just wanted to verify that i should be using the 8.1 package. Thanks
[Android Head-Units] ExtremeMOD:
The 8.1, 9.1, 10 and 11 version of Android are all fake. In reality these units can only run Android 6, 7 or 8. MOst common is 6 and 8.
[Android Head-Units] jordantheripper:
Thanks for reply. So, can you tell me a guide to follow for flash my unit? thank so much
[Android Head-Units] ExtremeMOD:
The link is in the first post.
[Android Head-Units] jordantheripper:
I'm so so so sorry but I don't understand: in your previous port U said: "No, this mod isn't compatible with your head unit. The Android 8 mod is however."

and if I ask for a guide to follow U say: "the link is in the first post."

so, please, what guide I have to follow? can you please indicate me the link? thanks so much

Hello, i just bought the YT9216B one, is it worth it to upgrade ? and google maps is so laggy is it just me ?
[Android Head-Units] ExtremeMOD:
If done right, this package will considerably increase the speed of your head unit.
[Android Head-Units] jrigga39:
I got the restoration of the backup to work this time. Only thing i did different was put just the files listed in the directions in a new folder. I guess I had did something wrong or chose the wrong rom file before, not sure. but im back into the unit, where i started. going to attach a pic of my system info screen, just in case im missing something as to why it hasnt flashed. After looking at it, I downloaded the supermod for 9216BJ, this unit is just a "b" unit. but it also has the fake android 9.1 which i assumed would mean it had 8.1. So does this mean it actually has android 6 on it?
[Android Head-Units] jrigga39:
im trying to flash the new firmware again. The instructions say to only check the bootimg, android, and vendor, but i dont have a vendor file listed??
[Android Head-Units] ExtremeMOD:
Please share your Kernel version. Then I'll be able to tell.

Vendor isn't always present.
[Android Head-Units] jrigga39:
Ok i finally was able to get the flash to take. Everything is loaded now..i am curious though, my system info states that i have 1gig of DDR now, and i had 2 before. And this was a 2 gig unit? Any thoughts on why?
[Android Head-Units] ExtremeMOD:
Glad to hear it. Our software shows real specs while the Chinese ones are hacked to show fake data.

Check available RAM with an app like CPU-Z and share the screenshot.
[Android Head-Units] jordantheripper:
Just modified my unit and for this...thank so much. it works great.

Just an information: I stopped at point 2 (firmware and TWRP went great). It's necessary I finish other points (root, viper and car launcher) or U think I can stop here and ressemble unit in my car?
[Android Head-Units] ExtremeMOD:
It's highly recommended to install the package in full. Otherwise you're not really making any improvements to your head unit.

Root is key. You can speed up your device considerably with root. Make sure to check out "speed hacks" post in our signature.

Viper4Android - if you don't listen to music much, you can skip it.

Car Launcher - optional if you are okay with the stock launcher.
[Android Head-Units] jordantheripper:
Ok, finally I arrived to last step: car launcher. But I can't install ADB driver on my PC. first of all in the guide there is "copy extracted file in C./ADB". In "Info-EN.txt" there is inside: "don't use C:/ADB but C:/program files/adb instead". But all the two alternative give me error when I do: "Right-click install-en.bat → Run as Administrator".

Can U help me? thanks
[Android Head-Units] zeus_r6:
Any chance mine is compatible?
[Android Head-Units] ExtremeMOD:
The instructions you have are old and no longer apply to Android 6. Please ensure you have downloaded the "V3" package.
[Android Head-Units] jrigga39:
Thanks for the reply..another issue im having is viper doesnt seem to be effecting my sound at all..ive tried every mode..ie headset, even with my phone bluetoothed in and still nothing. I get no errors or anything..just no change in sound...
[Android Head-Units] ExtremeMOD:
Turn on some music and then check the driver status in Viper. Post the screenshot here.

Also make sure Viper is turned on.
[Android Head-Units] jrigga39:
Oh im sorry i fogot to mention..im trying use it with spotify. Will viper only work on locally downloaded songs? Amd not through 3rd party apps?
[Android Head-Units] ExtremeMOD:
Will work on anything aside from the built-in FM Radio. But try first with an MP3 file.
[Android Head-Units] jordantheripper:
Surely is my fault but I can't find it. The only V3 package is referred to Android 6 and, inside, there is the same wrong guide:cry::cry::cry:
[Android Head-Units] ExtremeMOD:
That's really strange. We checked all the packages 2 days ago. Here's the proper guide.
[Android Head-Units] jordantheripper:
I's the same guide that I followed but It doesen't work. I tried to follow link included in the first line (https://4pda.to/forum/index.php?showtopic=672503&st=1460) and in that forum they say to install normal app called "Car launcher.apk" (updated to 15.09.2021).

but surely I can settle for everything I've done up to now thanks to your help and that's okay for me. Car launcher is not so important for me. Thanks for your precious help
[Android Head-Units] ExtremeMOD:
That's really strange, again. You don't need to mess with ADB in Android 6. All you need to do is to install the launcher and then uninstall the stock launcher through Link2SD app. Are you sure you're following the Android 6 and not Android 8 guide? Android 6 is further below in the document.
[Android Head-Units] zeus_r6:
Can anybody answer my compatibility question? I would really like to install this on my head unit!
[Android Head-Units] ExtremeMOD:
You have Android 8 installed. You can install this mod if you wish to rollback to Android 6 (recommended). For that, you will need to find a compatible preloader.

Before you do anything, check the info on YT9213AJ in the original post. See if you have the audio chip installed.
[Android Head-Units] zeus_r6:
There is no audio chip installed. This is something that can be physically added, correct?
[Android Head-Units] ExtremeMOD:
Yes you can add the TDA7729 audio chip but that will require adding some other components as well.

Without it, none of our mods will work.
[Android Head-Units] jordantheripper:
Thanks for your advice...now I finish modify my unit. Tomorrow morning I will reassemble the unit in the car. That was so great. Thanks for your patience......
[Android Head-Units] RealALCoL:

It's not an Android 10 but rather 6 or 8. Can't say for sure without seeing the Kernel version. These units don't support Android beyond 8.

Amd no, your head unit isn't compatible with this package.

[Android Head-Units] nate_white_truck:
I realize that your package is not for the 9212 HU, but I have 2 of them. One is a 7" that I have been trying to install your 9216B package on. (Thanks for the test point recovery video!) I keep getting stuck trying load the ROM_USER file, as Flashtool reports an invalid range, as per the pic below.

Since I am stuck here, are there any of your Devs in the USA that I could send this device to? I really want to use your rom on this device, as my other installed HU is also the same 9212B hardware, but with a 10" screen. If this one can be made to work, it should be safer to flash my installed one.

Alternatively, could you point me to where to get a 10" version of the HUs that your rom's can work with?

Thanks!

Nate WX
[Android Head-Units] ExtremeMOD:
You won't be able to install 9216B on your head unit. Restore your backup.

We can do custom development but we're located in UK.
[Android Head-Units] nate_white_truck:
Thanks for both your time and expertise putting all this together! I realize this is not the design for your Roms, as I have read the WHOLE post, including on page 17 post #334 where you said "Wrong thread. Your head unit model is not discussed here. There are some users that have reported successful installation of the YT9216B software package, so if you feel adventurous - try that and let us know if it works. Just don't forget to fully backup your unit first."

Should I start a new thread asking for help on this unit? I see that there are several users here and all over the net that want to make this variant work.

Meanwhile, in the YT9216 Dump in your first post, the instructions for the "Install First" folder describe installation of the smaller ROM_ file before the installation of the _USER file. However in the #300~ section of these posts you say that the smaller ROM_ is only needed for restoring a backup, and not needed for a otherwise working unit. Am I confused, or could the memory dump install PDF be more clear?

Again, thanks for both all the work, and the donations to a charity!
[Android Head-Units] ExtremeMOD:
Restoring backup means not reviving the head unit. So to restore, only use USER_ROM file.

To revive, use both. But your own backup. Not the one from another unit.
[Android Head-Units] RealALCoL:
can i ask u if this i fine for me? https://xdaforums.com/t/rom-root-twrp-guide-yt9216b-chinese-android-head-unit.4007063/

[Android Head-Units] ExtremeMOD:
No you can't. Not without risking bricking your head unit. In order to upgrade to Android 8, you need to do highly advanced tasks including hardware tinkering. We do not recommend this unless you really know what you are doing.
