[ROM] [ROOT] [TWRP] [GUIDE] YT9216B Chinese Android Head Unit

So... how to root your device?
how to flash twrp?
You can use this pre-rooted firmware, with included twrp.
-Build type is userdebug, means u can enable multi-window mode in dev settings
-Based on latest available firmware
-Root
-Busybox
-TWRP
-HIFI enabled
-UI1 Launcher
-FM Radio with RDS and save manager.
-TPMS (working with cheap chineese usb units)
-DVB-T & SDR (required RTL2832U)
Its backup of system i already have modified for myself.
It means, its branded to Ford Mustang all the way.
U can do this to get rid of that branding:
-choose another bootlogo.
-flash new bootanimation.
-install stock (not modified) UI1 launcher
To get ADB, i recommend this app:
WiFi ADB - Debug Over Air
Download:
YT9216B_00002_V004_20191012_HIFI_V3.zip
Factory settings password: 8888
Important note: Android 8.1 Go is just chineese marketing trick, in reality this head unit has android 6.0 (api lvl 23, not 27 as 8.1 should have).

folowed V4A Rom Inclusion
So, ViPER4Android included in ROM.

Instructions
Prepare:
- download and unzip archive from my first post
- make/buy USB A male to A male cable (for photos see attachments)
- install drivers from SP_Driver folder
Backup:
Just in case make backup (readback in ATC Flash Tool)
I didnt done it, so if u want, search for guide online
Flashing process:
- open flash_tool.exe from ATC_Flash_Tool folder
- select Download-Agent MTK_AllInOne_DA.bin from ATC_Flash_Tool folder
- select Scatter-loading File AC8227L_Android_scatter.txt from Firmware folder
- make sure PRELOADER is not checked. (There isnt any in in my fw. Just in case if u use this guide for some another fw)
- press Download button
- connect your USB A to A cable one side to PC, another one to your head unit. I recommend u to use that 4 pin usb port (that one with smaller plastic end), but shouldnt matter.
- press RST button on your head unit (use some pin, paper clip or toothpick)
-wait until flashing process ends. There should appear green message.
- press RST button again and let yout headunit boot.
- perform factory reset on your head unit to prevent any bugs
Flashing process error:
- happends sometimes
- disconnect your cable
- if possible, disconnect your head unit from electricity for a while
- press download again, connect usb cable back, and press RST button.
- check if your cable is not faulty.
- for homemade cable try to apply some solder on cable ends, check if ends arent shorted, use tape on them, or buy original cable

Sure. Mine is same.
HIFI is just EQUALIZER preset for best result. Included into firmware.
But today i want release update. Its worth to wait.

ok I'm waiting for release update

How can I install stock launcher?
and change the boot logo and animation?

hello already installed this version this top. I detected a bug in the active rear camera but not the image. How much boot animation should give to choose another for those who do not have Ford car. The torque app and tpms should be optional to install. this is my opinion of course you have developed the firmware to your liking to which you are top. If you don't mind you could develop a version with only root busybox twrp and Hifi. unaware of viper audio but it's top. in short I congratulate you

apps can be disabled.
Its more "backup of my unit" than ROM.
It takes space just in system, users which would know how to add something into /system would also remove everything they dont need to get more space.
uploading new version.
bootanimation can be changed in settings.

updated.

what changes did you make?

This top. How can I install another launcher and radio rds?
I wanted to install ui1launcher without modification

Radio should already support RDS.
Launcher can be pushed into system.

Just wondering if this will be compatible
my system shows i have
android 9.1
XY auto 3.1 (8227L) same as MCU
but yours is showing android 8.1 ?

mine was also android 9.1 "fake" and now after updating with the firmware provided here is 8.1 go

No wonder Android auto doesn't work
quite happy to give this a try but want a failsafe of backing everything up first
anyone know how to do that prior to upgrading

Zdravím, nedaří se mi spojit HU s počítačem, můžu poprosit o pomoc? Děkuji

Would this work if my unit is yt9217b instead of yt9216b? I tried flash TWRP myself but almost got caught in bootloop

My radio doesn't allow me to save channels as i desired

Hi Guys,
I'm using chinese double din android stereo in my car, i don't know the brand (no label or sticker on the box or on the device), when i start the radio system shows pre-saved frequencies at the memory, i'm changing frequency and want to save to memory (like first one) when i hit to save button it saves after the closest frequency, for example if want to save 89.6 FM to memory it saves after 89.3FM directly, i couldn't find the delete pre-installed channels (keep my finger on the memory didn't work, tried the drag saved frequency didn't work too), there is only self motion search button on the interface and it's scanning all frequencies and saves automatically to memory.
as you can see attached radio settings, there are two options, if i select FM INSIDE or AUTOMATCH my radio works, but if i choose the NXP6851 radio app doesn't even starts(it's crashing when i hit to radio button).
I've downloaded couple of tuner app from forum(like MTCFlatRadio) but there is no sound with those apps.
Is there any fm tuner app i can use with my stereo?
My system info and stock radio app's pictures as attached.

My unit has the same issue. I think it's an issue of "Radio" app version.
A question for others to help us - is there a way to check the version of "Radio" app in our units?

first of all thanks to @gouster3 for his post.
Here is what you need to do, after this operation your radio would not let you save stations in desired order but radio app will work much more stable and your device will be rooted (no more bad reception or changing station automatically)
You need laptop, male to male usb cable(never ever try to do this operation through wireless ) and a paperclip or toothpick to hit reset button :
-you can buy or make an male to male usb cable, making one is pretty easy
-find two usb data cables, cut the cable from half or as you desired
-there will be 4 cables in it red-white-green-black
-solder those cables regarding their colors : red to red - white to white - green to green - black to black, don't just wrap them eachother and tape it,it could causing flash errors, soldering is the solid & best way, after soldering the cables just tape them to avoid any short.
download this rom : https://mega.nz/#!Fh8RUQIK!NjTdZOhAU9CRqaUihy-kUR7CxwVmP5P2M8jrPKHo2Ro
Extract the archive to your desktop;
- install drivers from SP_Driver folder
- make backup of your device, i didn't do it because it's easy to recover from brick,but a backup is better way.
Flashing process:
- open flash_tool.exe from ATC_Flash_Tool folder
- select Download-Agent MTK_AllInOne_DA.bin from ATC_Flash_Tool folder
- select Scatter-loading File AC8227L_Android_scatter.txt from Firmware folder
- make sure PRELOADER is not checked. (There isnt any in in my fw. Just in case if u use this guide for some another fw)
- press Download button
- connect your USB A to A cable one side to PC, another one to your head unit. I recommend u to use that 4 pin usb port (that one with smaller plastic end), but shouldnt matter.
- press RST button on your head unit (use some pin, paper clip or toothpick)
-wait until flashing process ends. There should appear green message.
- press RST button again and let yout headunit boot.
- perform factory reset on your head unit to prevent any bugs
after flashing a good boot you'll see old radio app still there here is what you need to do :
-download FmRadio.app from here https://mega.nz/#!Ifp0wSLC!ht3m0p9br7gi8cpAXTl2EEmorLxy_s2lXA3ccWxGcVU
-copy to your usb memory
-install rootexplorer from google play store https://play.google.com/store/apps/details?id=com.speedsoftware.explorer
-goto root->system->privapps
-You'll see there is a FMRadio.apk
-Cut and move to your usb drive (or just delete it,but i don't like delete things) (do not left that old FMRadio.apk there, if you do that it's installing the old app no matter what you do)
-Switch to your usb drive and copy downloaded FmRadio.apk
-Switch back to FmRadio folder under root->system->privapps and paste the downloaded FmRadio.apk
-Give permissions 0764
-goto factory settings (pasword 8888) and select reboot
-let the device reboot and ready
-open the radio app and you'll see radio app has changed as attached picture
Original poster of this post is @gouster3 , his car is mustang so he edited images according to mustang.
if you want to change boot animation ;
go to here : https://forum.xda-developers.com/android-auto/mtcb-software-development/mod-boot-animation-toyota-t3351617
-download boot animation as you desired
-extract the archive file and copy to your usb drive
-goto system->media
-you'll see bootanimation.zip
-rename it (like bootanimationold.zip)
-copy your own boot animation to system->media
-change copied file name to bootanimation.zip
-set permission as 0644
-reboot the device
-walkthrough of how to change boot animation is here : https://www.hongkiat.com/blog/change-android-boot-animation/
after full reboot your boot animation will change and your radio will work much better, it's still doesn't allow you to save stations as your order but works much better than the old one,i'm still looking for better radio app,if i find one i'll share here.
Your side buttons can loose calibration after this operation,to fix it go to factory settings->touch calibration
If you have reverse or forward camera it could go black after this operation, to fix it factory settings->Protocol Parameter Settings->Reverse video resolution settings->NTSC/PAL, save and your cameras will work fine(no reboot required.)

Hi Sheshman,
it's good that you've found a solution on this issue. Well done!
I'm not ready to change firmware on the unit. As it is, the unit serves my main purpose of using wireless CarPlay. When it works, don't touch it!

yeah i'm using for same purpose too (car play,screen mirroring etc.) but the radio was itching my brain you know , this unit is cheap and does the job perfectly, don't change the firmware if you don't need to (it's painfull process as you know).
Cheers

i did my tests about it couple weeks ago, android auto successfully paired and connected every 2 or 3 times over 10 tries, my problem was my phone,i'm using xiaomi mi 8 lite, when i try to install android auto from play store it says your phone doesn't support this app and not installing, so i downloaded the anroid auto app and installed manually to my phone,it works but really glitchy (i don't know it's the right word),so i assume that my phone causing the problem but i don't have any other brand to test it, what i can say is basicly it works on this head unit but i think it needs little bit tunning to make it work.

Currently the Ownice K5/C900 has two different MCU versions and cannot be mixed, you need to distinguish which one you are using to download the correct MCU. To determine the right MCU, please go to Settings -> System -> About to see current MCU parameters of the head (see illustration below).
MCU version
T7.4.3-220-10-A4C681-190827
Observe the red underlined portion and determine as follows:
If the current red line is A466, the MCU is the Radio 7786. Download the first MCU with Radio 7786.
If the current red circle is A4C6, the MCU is Radio 7708. Download MCU with Radio 7708
After downloading the correct MCU for your head as instructions, extract and copy the file (e.g.*68a1a82a-ba3d-11e8-b378-0f810ac331da*) to the root directory of the FAT32 formatted USB.
Step 2. Update the MCU on the top
Plug the USB into the head, go to "Settings" -> "Vehicle settings" -> Update MCU -> Select the USBx tick (x can be 0,1, 2, 3, ...) -> The head will automatically identify and start updating the MCU -> Wait for the process to complete the first will restart itself and the update process was successful.

Looking for a developer who is kind enough to modify the MtcDialer program created by @f1x or create a similar program to make it work for Allwinner T7 and other allwinner headunut.
Update: The bluetooth app supports android.intent.action.CALL but does not work with google voice command.
But works on Google Go (lighter version).

thanks keep up the good work

even after rooting the device, my 4G dongle doesnt work, Im using ppp3

Wow .... Great post... I really thank you... I have had the Ownice C900 system for my Mazda6 since January 2020.It is away better than the factory Original System especially for the 360 birdview.

Hello, I would like to ask if there is a solution to the problem with RDS to be visible, ie to show the names of the stations

After combining the files to create system.img, i extracted the image with image extractor and made some small apk swaps. I repacked with image extractorm ran the checksum calculator and split the image with hex editor to 400mb. However, the files are completely skipped when trying to flash onto my radio. Is there something I'm missing or doing wrong when I extract with image extractor? Should I repack as a sparse image or ext4?
Thanks for any suggestions.

does anyone have a weird sound when the Head Unit starts, a buzz sound?, and whenever I navigate through the menus there is some a little noise.
The head Unit is getting quite hot, always above 70°

Before doing this, you should install the cert file attached in the OP first (unzip it and click to install).
Note: You also need to be connected to the internet while doing the activation.

Instalé la pantalla y luego de modificaciones en el cableado del canbus pensé que ya estaba todo resuelto pero por momentos me aparece la alarma de la imagen en mi vehículo y no me permite apagar, tengo que apretar varias veces el botón de apagado para que recién se apague.

Hi @tribalfs, if you find the time, could you add some context and experience to this post? I read your post after searching for reviews of the K5. It does not seem to be very popular, don't find a single review on youtube... but very feature rich.
I am not quite sure how to place this, as I am missing experience and in general also a market survey.. no idea what is cheap and what is expensive, what is good and what is crap.
Is this one in a thousand Chinese generic cheap (and bad?) radios, full of features, but none really work? Or is it actually a decent product?
Is it problematic that it "only" runs on Android 7?
Is it the only ownice Radio which supports 360° camera system? I notice that some other models have other more favorable features, like built-in 4G, better DSP, Android 10, ...
Your opinion is greatly appreciated!

- 21st July 2020 (exactly same as 21st April,only 2 files to fix bluetooth have changed)
How to install firmware:
Extract and copy all files from the downloaded firmware zip into the root directory of a USB stick. Files must be placed in the root directory, do not put in a sub-directory/folder at all. Files for a full firmware for the Ownice C960 include the following 10 files (depending on the rom there may be less or more than 10 files):
408930e4-c1fc-11e8-8a06-2b5b8f8a7e48

6cdfbbd8-9a00-11e7-8c64-33bdecde7c40
The Ownice C960 has several methods to install the different firmware depending on the situation and the current operating status of the head unit, for example, if the head unit is still bootable into the operating system, it is possible to use method 1 to install the firmware from the software of the head unit.
If the head suffers from being stuck at logos or other problems you need to move onto method 2 of installation using a recovery method. If both method 1 and method 2 do not work there is also a 3rd method but this is not listed here, please follow the instructions on this forum: https://xethongminh.net/threads/huong-dan-chay-firmware-cho-dau-android-ownice-c960.2940/
I. Method 1 (Rerun or upgrade the firmware of the C960 player via the installation interface)
Plug in the USB drive containing the firmware and go to Settings (Settings) - Car settings (Car Settings) - Update (Update System)
-If you need to wipe the system check the box to Clear data and format Flash, then check the box for USB
-If you want to flash without wiping check the box for USB only (if you have problems with this method try wiping first before moving onto another method)
Wait for the update process to complete the reboot is successful.
Installation Video: https://youtu.be/2JvAcrLPvRo
II. Method 2 (Rerun or upgrade the firmware for the C960 player when unit cannot boot)
This method is especially useful for those who root or unlucky and have system issues causing the head unit to be unable to boot into the system. There are 2 ways to do this method:
Option 1 (I have not been able to get this method to work, this is written exactly as translated from Vietnamese):
Trapping system errors, pressing into mode Update the firmware
Error traps are a simpler way to do the first way because you don't have to remove the head from the car to short the KEY-2 cable like the first way. How to do the following:
Proceed to plug the USB containing the firmware prepared in step 2 to the beginning.
Turn on the electric car to start the car, when the head has booted on the screen (including in the state of logo hanging), proceed to use the RST hole stick on the screen to restart the head, right when the head of the Ownice logo appears then immediately turn off the car keys to turn off the head. Wait for 5 to 10 seconds, then turn the car lock on again, this time, it will jump into the firmware update mode if it detects that the USB containing the firmware is plugged in.
Option 2: Short KEY2 cable to ground (the head unit cover or car chassis)
Connect a USB stick containing the firmware
Short/connect and hold the KEY2 wire to a suitable grounding point (holding to the metal chassis part of the head unit works fine)
Stick a pin or toothpick into the RST hole (RST stands for RESET) on the front of the monitor to reboot (while keeping the KEY2 wire grounded)
Wait until the screen turns on with text showing the firmware update process is in progress, at this point disconnect KEY2 from ground
Wait until the update process is completed, it will automatically restart and operate normally.
Decompiling Firmware:
Firmware files can be decompiled and edited however I'm not going to go into detail in how this is done as its very in depth and I am not 100% sure my methods work 100%, however for those that want to attempt this I do have a link for a tool that decrypt's encrypted files, you can download the tool here: https://www.androidfilehost.com/?fid=4349826312261776408
Unfortunately I do not know much about the tool or who to thank only that it's called Kaier Support Tool and its by Darkleo - Thank you dev's whoever you are!
Custom Firmware:
There is now a custom firmware available for our units. This firmware is called RedMOD
Website for RedMOD is here: https://firmware-an21.wixsite.com/redmod
RedMOD is an all in one replacement firmware for our units. It replaces the stock firmware to give us more options, features and settings. To know more please look at the website link above but note that everything is in Russian. I have been able to download and use this firmware using just Google Translate.
This firmware is not free! You must pay the developer for access to the download and you must not share this firmware! If you share this firmware your post will be reported!
Some of the features I have found useful so far in this new firmware:
Remapping Canbus Keys (Most keys can be remapped)
Better display dimming options (Auto Dimming)
More reverse camera settings (custom reverse lines etc)
Better automation settings for when the unit wakes up (choose apps to run at startup etc)
Customisation of status bar (Add or remove items like menu button, time, temperature etc)
Much much more
To get this firmware you must register on RedMod forum and then follow the instructions to download:
http://red-mod.ru/forum/viewforum.php?f=13&sid=e1d8a806c50a172dd889ccff62506225
The cost is 2000 Russian Rubles or 38 US Dollars. For me in the UK the exchange worked better to send Rubles and the cost was approximately £26. Once you send payment the admin will change your forum access so that you can access the download area. Make sure you register with the correct information and only get access to and download the firmware for "ANDROID 8.1 - Intel TS9" as this is our device.
I am not affiliated with RedMOD and cannot be held responsible for anything that may happen to your unit as a result of using this firmware.
Root:
All root files up to 15th January 2020 firmware come from the Icar Vietnam forum found here: https://xethongminh.net/threads/huong-dan-root-dau-android-ownice-c960.3115/
Root files after this date have been created by me
- August 28th 2019
- December 23rd 2019
- January 15th 2020
- March 2nd 2020
- March 13th 2020
- April 21st 2020 and July 21st 2020 (same file can be used, exactly the same for both firmwares)
How to Root:
First you must download firmware and root files that match.
Install firmware as described in the firmware section.
Extract and copy the files from the root zip file found above into the root directory of a USB stick and plug the USB into the head unit
Install MagiskManager.apk (the downloaded zip file includes this file) found on the USB stick using a file manager on the head unit
Go to Settings (Settings) - Car settings (Car Settings) - Update (Update System) (Do the same procedure as updating the firmware) and check the box for USB only
Wait for the update process to complete and the reboot is successful.
Open MagiskManager and check you are now rooted! (if you are not please rerun this procedure)
How to make your own Root file:
The root file is simply a boot image with Magisk. Nothing more nothing less. However the original boot image is encrypted so I will go through the steps of how to get the root file for each rom.
First download the tool here: https://www.androidfilehost.com/?fid=4349826312261776408
Unfortunately I do not know much about the tool or who to thank only that it's called Kaier Support Tool and its by Darkleo - Thank you dev's whoever you are!
Download the firmware you want to root
Extract "4192eb4c-c1fc-11e8-8f83-a7a51df1443b"
Open Kaier Support Tool
Select the "4192eb4c-c1fc-11e8-8f83-a7a51df1443b" file and click decrypt
The tool will ask you to save the file, save the file as "boot.img" and transfer it to a USB stick
Put the USB stick into your head unit and open up magisk (you must have magisk installed)
Click install on Magisk (not Magisk Manager) and when it asks click to "Select and Patch a file"
Patch the "boot.img" we put onto the USB stick
When done Magisk will save the patched file into the downloads folder
Move that patched file onto your USB stick and head back to the computer
Open up Kaier support tool, select the magisk patched file and click encrypt
When it asks to save call the file "4192eb4c-c1fc-11e8-8f83-a7a51df1443b"
"4192eb4c-c1fc-11e8-8f83-a7a51df1443b" is now your root file!
Follow the other instructions to flash firmware and flash root but just place this new "4192eb4c-c1fc-11e8-8f83-a7a51df1443b" on your USB stick instead
Change Startup Logo:
For instructions on how to change the startup logo please follow the video here: https://youtu.be/V9xC6A41q7Q
Important things to note:
You must place the image on the root of a USB stick, it will not work if it's in a directory, you may even have to reboot with the USB plugged in before the unit will find the file
The image MUST BE an 8bit BMP file with a size of 1024x600

Thank you, I was thinking of doing the same as you. Because I believe that the C960/K6 is one of the best android head units available today. As one C960 user, I will cooperate with this thread as much as possible.

Currently, I have two C960s with different resolutions, S1008W and S1010V, and they also have different firmware.
The resolution of S1008W is 1280x720, but if you update the firmware distributed by Ownice Vietnam here, the screen resolution will be broken like the attached image.
I can't speak Vietnamese, so when I contacted Ownice official support, they sent me a small file to fix the resolution issue.
This update file actually recovered my S1008W so please add it to the op, thanks.

Hello . Just installed the C960 on a Nissan Serena 2019 . For the moment i have 3 problems :

Thanks for this, I wasn't aware of the screen resolution differences but will update the op accrodingly
Before I do though can you clarify a couple of things
You say firmware is different on the 2 units? Completely different or same firmware just different file for resolution?
The attached zip, just place the "408930e4-c1fc-11e8-8a06-2b5b8f8a7e48" file on a root of a USB and update using system update option?
Can the "408930e4-c1fc-11e8-8a06-2b5b8f8a7e48" file be added to the USB stick containing a full rom to flash the whole system?
Thanks in advance

2. Steering wheel controls not working ( i have canbus, i try to reprogram the buttons from settings) .
3. The original back camera is not working ( i have canbus)

Welcome to the thread
I will try to help but information on this unit is limited and I don't have all the answers
1. Do you currently have AV out working and paid for the AV out upgrade? I don't personally use the AV out option so cannot really comment on how exactly this should work but in theory I would have thought what you are trying to do should work
2. No issues with steering wheel controls here, being canbus they are not programmable as far as I am aware at the moment, do you have the correct canbus adapter box plugged in and the correct settings set for your vehicle in car settings?
3. If the original camera works through canbus I can only assume it will not work at all. Backup/reverse camera has to plug into the RCA input on the back of the head unit
I hope this is helpful

Just unzip it to a USB memory and run the system update. The update time is a few seconds.
In addition to the resolution, the S1008W has another difference: it has a built-in 3-axis sensor and has a vertical screen UI.
However, updating the firmware for 1024x600 systems also loses this functionality, thanks.

1. Yes I paid for AV out and is working, but is mirroring everything from HU , maybe is something in settings. When I will find out I will tell you.
2. The steering button are not a big deal , but I wished the volume button to work . Can you tell me if you make the connection to steering buttons with wires or you have the connection in the harness of the HU ?
3. I think the problem is the original camera of the car . I read on some forum that I need to take the signal from another place because the car have aroundviewmonitor ( 4 camera) , parking assistance and propilot ( self driving option) . I will update the results when i have time to teardown the car again .

V11.1.1_20200421 has been released in i-car Vietnam.
And I installed magisk by the procedure introduced in this thread, but I can't install youtube vanced.
The installation completes successfully and the folder is created, but the contents are empty.
Please let me know if I'm missing something.

1. I have spoken to Ownice and AV out can only mirror I'm afraid
2. I have a canbus decoder for my unit, it works well
3. Yes if you have that sort of system it needs rewiring, I cannot help with that I'm afraid

Haven't tried youtube vanced myself yet on this unit but I can see you are trying to install it as a system app, have you tried just to install as a normal app and not a system app?
Op updated with latest April firmware and root file

Nissan Serena S-Hybrid 2019 Japanese edition

I hope you guys can help me
In my car my aircon shows "HI" and "LO" temperature settings, when changing temperature it goes up and down in 0.5C steps showing "LO" instead of 15.5C and "HI" instead of 28.5C
However the headunit doesn't show HI or LO and just shows the temperature
I am trying to modify the APK to fix this but need your help, what I need to know is:
Does your unit show HI and LO values? If it does what temperature does it set them to HI and LO respectively? What increments does your heating change, is it 0.5C like mine? Do you have 2 separate temperatures for left and right side of vehicle or just 1 temperature settings for whole vehicle?

Sorry to move through your question, but when you linked to your own thread also mentioning the k_support tool, I realised I had seen it "somewhere" before. It was of course on 4pda.
that was some years ago when I wanted to discover everything related to Joying and other helpful stuff.

hi all, my unit is a TS9 unit and I'm looking for root... can we cooperate?

huh, anyone?

Glad to see this thread, I have the same unit on my Kuga 2015.

Anyone know what is the difference between BC6 and BC8 ? And what type of DVD I need to attach to the HU ? I have right now a Lite-on DvD .

What's the difference between the c960 k6 and the s9285 k6 if any, I'm looking to fit one of these in a 2009 ford fiesta

Junsun V1 pro UI 3.0 display buttons don't work after screen calibration.

Hello,
I bought a Junsun V1 pro with UI 3.0 Interface and 8GB Ram + 128GB Flash Storage. It works quite well for me. However the Touch scrren calibration was a bit offset. So i searched the internet and found out, that it is possible to calibrate the touch screen after pressing the display with five fingers for some seconds. The screen calibrations also worked well but after this i relised, that my touch (or front) buttons don't work any more. I tried to reattach them to functions using the Touch Study menue in the factory settings menue (8878) but nothing happens there when i press the button (which was possible before). Does anyohne know this issue or has an idea how to solve this?
During the screen calibration you have to choose the resoloution and the direction of the first touch point to click. No possibility or options for the touch buttons.
Do you need any more information or pictures of the device?
Kind regards

I think I have a clue whats going on. When i play around with the settings Touch Origin X and Touch Origin Y I can get the display edge to work in touch study. However, i don't really get the left side to work. Could anyone take me some pictures of the factory settings menu "other". I think comparing the settings could help me out.
Kind regards

Hi,
yes I was able to fix it with a backup of the factory settings menu. I got it here in the forum:
Post in thread '[Firmware] Junsun V1 8667Q - 8G/128G VHD QLED' https://forum.xda-developers.com/t/firmware-junsun-v1-8667q-8g-128g-vhd-qled.4405475/post-87647423
This is for HUs with 8667Q. I'm not sure if it will work for others. First make a backup of your current settings. You need an usb Stick with FAT32. Than download the backup and Import it to you HU:
1.Enter the factory Settings with code 8878.
2. Plug in the empty USB Stick to the 6pin port
3. Go to "MP Mode" and click the right Button (settings to usb)
4. Disconnect the usb Stick an save the Backup file to your PC (it is a *.bin in the root of the usb Stick)
5. Empty the usb Stick and copy the Backup file from the link above to it (you have to unpack it first). So dont copy the *.rar but the *.bin in it.
6. At your HU Enter the factory settings menu with Code 8878 and go to Menu "others"
7. Insert the usb Stick to 6pin Port. Click Import at the right top
8. I think your device will restart. Touch buttons should work again (if the issue was like mine). Unfortunately the Backup is polish. So May you should habe a Look how to change language before you Import it.
Do all of this on your own risk! I'm not sure if it will work or even crash your device.
