Hi dear all,
I just recieved a new android car 2din head unit, it's a MTCD version with the last firmware version 5.1.1 android+KD+04.05.2016 and I have an issue with the display.
I have an inverted colors on the display.
No way to return to real colors.
I have wiped all users settings in recovery mode.
I have tried via adb to set pm clean com.android.systemui with no success.
Can you please help me ?
Thanks
Artius
The only thing that comes to my mind is this :
Have you checked the "developer options"?. There is a option witch does invert colors. If it is not switched on you might just turn it on and see if solves your issue.
Thank you Marmalux.
I will try your solution this evening
Do you know how to activate "developer options" on this android 5.1.1 MTCD unit ?
Because when I use 126 password in the advanced option I dont have any item with developper options.
Thanks in advance
Artius
Developer options are android specific options, and is not the "factory setings" menu. In main setings menu at the end you should find the developer options.
Regarding the password for factory settings you can also try "m12345" or "m123456" or "587" (this one i'm not sure, but it is definitely begining eith 5, you can find it in the wiki of xda)
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.

Users, use “Compatible Mode” if you plan to install other sound mods. No other sound mods included in ROM.
Screenshots
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
Hello,
It happened to me when I updated my system, after system updating my air conditioner app stop working my head unit system is Quad core T3 p1 android 9, I solved the problem, and I would like to share the solution if someone facing same problem.
The solution is to go to settings, car settings, extra settings ( password 123456 ) then select car model or something related to model, then you will be getting into car selecting menu ( pic is attached for reference ).
Please be careful when choosing the car model, it should be exactly the same as yours.after that you will get an APK downloading, also MCU update, system will be restarted automatically after the update is complete, done
notice: your head unit should be connected to WiFi for the MCU updating process.
Regards,,
Consider before taking a post here and please make sure whether you are writing in the relevant thread!
Check your device configuration if it relates to this thread. If not please dont facilitate the proliferation of misinformation, otherway please feel free to share your knowledge and experience or take a question.
I feel the neccesity to create a separate thread for this version of HU since it makes always confusions whether the revealed information relates to the owners device or not. On the other hand some of the applied methods are way more different compared to the PRO series that mainly derives from the differences of the UI thus this thread will ease that confusion.
That is why i will share here all the methods of troubleshoots i have collected so far.
Basic codes:
Settings ==> Car Settings ==> Extra Settings ==> 8888 (restricted settings)
Settings ==> Car Settings ==> Extra Settings ==> 123456 (advanced settings for left panel touch controls and ect.)
Settings ==> Car Settings ==> Reset Factory ==> 7890 (wipe data - all 3rd party app. will be deleted)
Settings ==> System ==> Developer Options ==> 7890 (usb debug and ect.) ==> USB debug Pw.: [email protected]
Advanced Developer options:
Settings ==> System ==> Developer Options ==> 7890XX , XX=Current time in hours 24hrs format. If its 7 o clock in the morning then the code is 789007
Do not try any of these codes with no reason and without the adequate knowledge!!!!
If the HU is working well forget it!!!!
Use these codes only on your own risk and reponsibility!!!!
TO BE CONTINUED
Follow on topics:
- Method to force update and wipe data cache as a solution of a boot looping.
- Setting up the left touch panel including button lights activation with color change.
- Method of installation and activation NEXAI Toppal AI (key not included, must buy)
- Firmware update method.
- BT issue
Method to force update and wipe data cache as a solution for boot looping.
Right now there isnt any known method for this version of the HU to restart in recovery mode to make a wipe cache but . . . .
There is a working method to force the HU into update mode even if it stucked in boot loop.
-Get a paperclip, needle or toothpick
-Get an USB flash drive 1-32 Gb, Format it with FAT32 file system with the default volume size as it is provided by WIN11
- Open the link (provided by JUNSUN support)
https://drive.google.com/drive/folders/1QGzYyTV2_S7W2wmr7mP3uSgsWAxzyONb?usp=sharing
-Extract the ZIP file and copy all 3 files to the flash drive root directory.
- Get in the car and connect the flash drive to the 4 PIN USB outlet.
-Put the key into the start lock and turn to ACC/Power on wait until the boot logo comes up.
-Take the paper clip and press the reset button 1x, just press, dont hold
-The device will restart and when the boot logo appears again switch the power off/ turn the key/ ignition off immediately.
-Wait 10 SEC and turn to ACC/Power on.
-If everithing went well a "green loading bar" shuld appear on the screen with the tex "UPDATING" or something similar, i could not read it properly because it was visible only for a couple of second due to the size of the upgrade files ~2kb . I think these files are something that is like ADB (Android Debug Bridge) and initiates an update recovery command.
-The update took me approx. 5 mins.
-After the update all 3rd party application will disappear, eventually its like a wipe chace.
So far this is the only known working methode to get out from boot loop without flashing the HU.
Ps.: If it does not work try the other USB outlet or try another flash drive. If it still does not work dicsonnect every cable from the HU and reconnect only the power supply and USB and try again all the combinations that i previously mentioned.
Setting up the left touch panel including button lights activation with color change. Video under the link.

Link to Color.apk
Basicly the so callaed color.apk is a preinstalled sys. app.. With the following method you can enable the aplication:
Got to SETTINGS > CAR SETTINGS > EXTRA SETTINGS >> 123456 >> CONFIG INFO >>> tick the box, select >>> COLOR
after that the aplication should be visible. If not follow the link below:

Method of installation and activation NEXAI Toppal AI (key not included, must buy)
Installation:
https://www.youtube.com/watch?v=G9LUWAZGiAg&t=95s
Link for the NEXAI APK files:
https://drive.google.com/file/d/1tDDi05owYzdGayswq-Alj8GpKQhXZJtX/view
Activation:
Firstly you should buy an Activation code.Once you got the code then the steps are as of the following:
(1)Copy the activation code sent by the customer service, modify the SSID of the hotspot to the activation code, turn on the WIFI of the radio and connect to the corresponding activation code(SSID), and the activation will be successful after successful networking.
(2)You can enter the ‘NEXAI Voice’ application to check whether it is activated. Once the activation is completed, the voice control function will be available and the Nex(Floating Robo) will change the color.

Do you think there is any chance this would work on a FF_866X model bassed on the MTK8667 chip?
the normal update procedure is to place the firmware update files 8667.bin and 8667.upd files on the root of fat32 usb into 6 pin usb slot, turn on and tap screen, it should show "detected" in top left corner then it updates, however my update files must have been corrupted as update failed and it seems its wiped the unit as now it shows detected but then goes to fastboot mode see pics
I have tried many different firmware versions but it just goes to fastboot, I have tried a few different usb drives and tried both the 6 pin and 4 pin slots but still nothing
Solution for Bluetooth connection issue / failure.
After installation of a third party launcher app or upon updating the firmware it is a common problem that the bluetooth connection does not work (BT device is not visible and unable to discover another device). And also if you check the the MAC address of the BT device it will be value "Null"
With the following method you can activate the built in BT device :
First you need to go into the bluetooth settings and check if there is a username and password. (Important: you don’t need to enter anything yourself, the name and password must be assigned automatically.)
Then
Got to SETTINGS > CAR SETTINGS > EXTRA SETTINGS >> 123456 >> CONFIG INFO >>> tick the box, select >>> BC6 (in some version it is BS6) >>> disable all the others >>>> RESTART
Now it should work.
If the checkmark is in the BC6 checkbox, then you need to deactivate it and put it in front of BC8.
If it is opposite BC8, then you need to change it to another checkbox, reboot the device, and do the same operation, but return the checkmark to the checkbox opposite BC8.
Restart and done ,

In my opinion your Boot Loader is corrupted that is reason why it can not be flashed.
The most valuable knowledge can be gained only on the bases of personal experiences. What i can recommend you not more just to make a try. Series of tries will lead to the success.

yes I have tried and doesn't work. I guess all I can do now is wait for the seller to reply to me
My unit just goes straight to fast boot screen no matter which firmware I put on the usb

Start to study ADB Shell and try to update it using shell commands via pc or replace your boot loader.

Dobrý den. Dnes jsem konečně namontoval nový Junsun v1 s Androidem 11 a jsem z toho rádia docela zklamán. Myslel jsem, že namontuju rádio, nastavím základní věci a budu hrát. Tak to rozhodně není. Nepřehledný, složitý, celý večer koukám na internet a teď už asi 3 hodiny pročítám toto fórum. Zjistil jsem, že RDS je nutno nastavit, OK. Logo vozu je nutno kdesi stáhnout, OK. Ale co mě mrzí nejvíc, když jsem rádio namontoval, fungovalo vše v pohodě. Ovládací tlačítka vlevo stále měnila barvu, čehož jsem si moc nevšímal s tím, že to pak změním na stálou barvu. Připojil jsem zadní kameru a vyzkoušel funkci. Podle schématu v manuálu nešla, našel jsem info, že se musím použít hnědý kabel a pak už to fungovalo. Ale pak jsem si vším, že ona tlačítko vlevo jsou potmě. Víc než hodinu jsem hledal v menu, kde by se to dalo nastavit ale nenašel jsem. Poradíte mi prosím někdo, jak to nastavit? Koupil jsem k tomu i modul OBD2, docela jsem se divil, že v jednotce není žádná apka k tomu, stáhnul jsem Torque ale ten se mi nedařilo nijak připojit. Zkoušel jsem to už dřív v mobilu, tam jsem se s ním sice spojil, ale komunikace žádná, Santa Fe CM2 2006. To ale zatím řešit nechci, teď mě nejvíc trápí ta tlačítka potmě. Děkuji za radu
Mod. Translation: Good day. Today I finally installed the new Junsun v1 with Android 11 and I am quite disappointed with the radio. I thought I would mount the radio, set up the basics and play. That's definitely not the case. Unclear, complicated, I've been browsing the internet all evening and I've been reading this forum for about 3 hours now. I found that RDS needs to be set, OK. The car logo must be downloaded somewhere, OK. But what saddens me the most, when I installed the radio, everything worked fine. The control buttons on the left kept changing color, which I didn't really notice except that I would then change it to a constant color. I connected the rear camera and tested the function. It didn't work according to the diagram in the manual, I found information that I had to use a brown cable and then it worked. But then I notice that the button on the left is dark. I searched for more than an hour in the menu, where it could be set, but I couldn't find it. Can someone please advise me how to set this up? I also bought an OBD2 module for it, I was quite surprised that there was no app for that in the unit, I downloaded Torque, but I couldn't connect it in any way. I tried it before on my mobile phone, I did connect with it there, but no communication, Santa Fe CM2 2006. But I don't want to deal with that yet, now the buttons in the dark bother me the most. thank you for the advice
