SP Tools YT9216C Not Working - Android Head-Units

I have been trying for months to install a new ROM with the help of amazing XDA users such as @gouster3 @viktorsaari @Blefish YT9216B_00002_V004_20191012_HIFI_V3.zip on my head unit and not getting very far. I am hoping someone has had similar trouble to me and can assist. I think the breakdown is something to do with SP Tools and the drivers.
I have installed the recommended drivers from MediaTek SP Drivers v2.0 signed.zip, installed the cdc-acm.inf via device manager and the preloader driver.
Attempted Flashing Process
Installed Signed Drivers
Reboot
Open SP Tools (administrator permissions)

Plug into USB Port 1
Reboot the HU
It just boots like usual, with the android logo. No activity in SP tools. Nothing downloaded, no flash progress at all. I am running Windows 10 64 Bit.

OK finally fixed. It was the USB cable that was faulty

Glad you got it working. Note for others, I had to take out the SD card on my HU, for some reason I could not flash it properly when it was inserted.

Hi brother am happy you were able to solve the problem.
I have similar configuration. See this...

I am interested in taking a full system backup using SP FLASH tool. But I have tried almost everything you did but my SP FLASH TOOL doesn't detect it. However, MTK DROID TOOL detected it. Also it is detected as adb device not com port.
What am I doing wrong. Should I be in fastboot mode or switch off mode. I tried with normal ON condition.
Can you explain the complete process

@Smarty_009 if you can connect via adb, why not backup from adb?
I would trust that over a system dump from SPtools....seems so finicky.
BTW, I assume you are trying this with the unit disconnected from power...I lost mind before trying that.

Hey. Thanks for your advice bro.
I tried with unit totally disconnected. Only usb connected to desktop. But com port appeared and disconnected immediately repeatedly in device manager. So I connected the head unit to car power supply and kept the car off so that only 12V supply and ground will be available and acc will be 0V. But it didn't detected at all. So I switched on the head unit and in factory settings changed between host and device alternatively then for short time it was shown in device manager but disconnected again.
So I can't use Sp FLASH TOOL.
Well I didn't knew that full system backup is possible from adb.
I will search on google.
If you have any details please help. Adb is working so I will do that.

@Smarty_009 you likely found this by now:

That's ok. We all get in to this once at least. Even I have done it many times. Without messing around you won't learn new things. I read your post what you did to your system.

Well if you saw my post then you saw that I was able to push an image only AFTER shorting the test pins. Pics attached for 3 MB designs (9216,17,18)
If you wanna do a quick test, try a "Readback" first.

Hi I have made a video tutorial on how to make stock ROM backup
Mod edit: inaccurate video link.removed.

Hi friends,
Have you are observed overheating of touch panel of your car stereo or hangs in your Android car stereo or system not responding or application keep crashing etc.
Then this video is for you. I have done this small modification in my car.
I made a small hole on sides of AC vents such that cool air blows over the heat sink of Android car stereo and two cpu fans of 12V take power supply from same connector.
Whenever the car stereo is turned ON the fans also turn ON and blow cool air over the heat sink to keep it cool.

Hi I have made a updated video tutorial with added info on how to make stock ROM backup.

Hipstreet W7 Windows 8.1 Tablet Help! Recovery Image?

I have a Hipstreet W7 tablet (Windows 8.1), the model number is HS-7DTB34-16GB and it's all messed up. Apparently a clean install of Windows was a bad idea because Hipstreet doesn't provide drivers for their devices on their website or through customer support. Admittedly this is completely my fault but I think maybe one of you guys can help me... Does anyone else own this tablet, and if so, would anyone be willing to make a recovery image I can restore to? Pretty please? I've been struggling with this stupid thing since almost the day I bought it. I just want it to work again. If anyone has a system restore point or recovery image I can restore to I would be so grateful. Thanks so much for any help anyone may be able to provide.
-Alex
UPDATE
So the HP Stream 7 Tablet has almost identical drivers. They all install very nicely and make my Hipstreet W7 run almost perfectly.
Those drivers can be found right here.
I highly recommend the first two things you install (in this order) are the Intel Chipset Driver, and Trusted Engine driver. Both are available from that link.
These two drivers seem to wake up/discover a bunch of hidden/inactivated 'devices' in the device manager list. It also give you your battery meter back and starts treating your tablet like a tablet again.
If you don't do these two first the other drivers from the HP Stream 7 page probably wont install correctly..
Funny enough one of the drivers from the HP Stream 7 page is the Goodix Touch Driver, but that alone isn't enough to get your touchscreen to work. (I've tried with both MSSL and GOODIX active in the BIOS). We also need something known as the 'KMDF HID Minidriver for Touch I2C Device'. I'm pretty sure this is the driver that is keeping all of our touch screens broken. I can't seem to find a Windows version anywhere and jleech1990's driver back up INCLUDES it but has no idea what to do with it. After installing the rest of the HP Stream 7 drivers there aren't any unknown devices left so I'm not sure where this goes without an executable package to install it with so this is where I'm stuck. I hope my update helps somebody get a little further. I put a few hours into this the past couple days.
That's all I got guys, I'll keep an eye on this thread for the next week or so...
check your pm!
ANy news on the driver?
You guys have any tips or a procedure or two on how to do a clean install? A friend of mine mangled up his Hipstreet in an attempt to get around storage limitations, so any tips would be appreciated.
Ok, so mine have sorted itself out somehow - I have given up and was trying to use it with mouse and keyboard. I have used the ineternal update of windows and suddenly the toudhscreen came back to life
so here is what i did in case anyone is stuck BUT WARNING I have read thet this doesnt always work so your millage might vary... I think there might be regional differences...
anyway. I bought y hipstreet of ebay in the UK. I assume its a UK version
I have backed up reocvery disk to usb drive and foolishly tried to delete the images partition which broke my OS and it wont boot
I have downloaded from a torrent the windows with bing image (X19-57135_SW_DVD9_NTRL_Win_with_Bing_8.1_32BIT_Eng_Intl_OEM.img) and using rufus made a usb disk of it
using the tablet with a usb hub i have booted the tablet with into the USB stick (pressing DEL during boot takes you to BIOS and choosing boot device just like on any windows PC)
I have installed windows from the disk, deleting all partitions and letting windows re-partition the internal drive.
That went smoothly.
Next installed driveres from HP as per post 2 in this thread. after that I had one unidentified device in the device manager and i have used update driver option and directed it to the Backed up drivers from post 2 which i have download and unpacked ( jleech1990's driver back - link in post 2) - It updated the driver, showed it as KMDF HID Minidriver but gave me an error in device manager and the touchscreen did not work.
At that point I gave up and just got windows to do its updates and suddenly it all worked - I guess one of the updates sorted it out but have no idea
Also, I am not sure how the activation works on this but once I had internet working windows showed as activated... I know others had issues re activation...

Thanks dude, I'll keep that in mind in case my friend asks me to do a repair on his Hipstreet.
Cannot even get mine to boot from USB... no idea why. I've tried using Rufus and the Microsoft Media Creation Tool....
It's a brick now... lol. Oh well.

hola tengo una Hipstreet W8 (Windows 8 totalmente brikeado si alguien me puede dar orientación de que hacer los pasos a seguir y una imagen de recuperación por que no la tengo se los agradecería , no importa que tenga alguna falla de táctil lo importante es revivirla esta muerta
The hipstreet W7 has a hidden sector in its small drive. In that hidden sector are the restore to factory settings files. If your W7 unit becomes corrupted, look at the edge with the USB receptacle for a tiny hole labeled reset. Insert a thin paper clip and press. The unit will boot just like it was first booted when it was taken out of the box. Anything that was added will be gone. Keep it plugged in because it could take a couple of hours to reinstall everything.

Hola tengo una hipstreet W8 ese modelo tiene el agujero que tu dices por que sinceramente no se lo veo, si tienes una imagen te lo agradecería
Any chance you guys have got a reset your password tool for local users? daughters changed her password and forgot it, and i cant find a usable solution anywhere, as i cant seem to get into the bios to change the boot settings.
How frustrating!! I have a Hipstreet W8 pro tablet and the hdmi wasn't working - long story short I decided to do a factory reset. Bad idea - I left it plugged it as recommended and now it's not doing anything at all - it won't turn off or turn on. There's just a faintly lit screen when I press the power button - I've tried the power & the volume buttons but nothing is working. I tried calling Hipstreet but the number is not in service. I also checked all over the tablet and there is no small hole to reset. Help please!! EDIT: Well I don't know what I did but I kept pushing buttons and it came on saying it was loading windows!! Hopefully this works!!
compatible drivers pack
i found this driver pack, i think is the same motherboard of hipstreet w8
w w w . mvapple. com/ 117 ?category=567688
or direct download for windows 8.1

Driver booster 6 would also work nicely. no need to dig for drivers.

Thank for this solution, but where can i find the latest firmaware MX Q-4k RK3229 (6.0.1)?
I guess I did something stupid...
Hi all,
First of all, I have managed to boot into recovery mode and got that menu screen, where you have the wipe data/factory defaults and wipe cache partition.
My stupid thing: I did both... (both cache and data /factory defaults.
Now, I've followed dnbsoundsgo0d guide, but my device is not being recognized by the tool... I'm currently downloading an MXQ_4k_2017.ZIP file I found for the device, but, I'm wondering if by putting this on an SD card, if I will be able to update it without connecting to a PC.
Any word of wisdom is highly appreciated. Thanks!

ROM / Firmware/ Brick Recovery for 7" Android Head Unit AC8227l YT9217 YT9218 1/16GB

ROM / Firmware/ Brick Recovery for 7" Android Head Unit AC8227l YT9217 YT9218 1/16GB
Thanks everyone who contributed in my effort to fix my bricked device. Here is all that I have found useful in successfully reviving my device.
The files shared here are the ones that worked on my unit (see specs and pictures below) If your device is different, it may or may not work.
If the device has dedicated radio chip inside, the Firmware number will show as YT9218, if no radio chip, then it will show as YT9217
Note: if your device is not bricked, Make a full backup before trying another firmware.
I hope it helps. (donations are always welcome )
Memory dump:
firmware 20181222 HiFi: (Link) (thanks mazepa2000) (May 2019 update below)

I hope it helps. (donations are always welcome )
Memory Dump Procedure via flashtool:
(Memory dump is only needed if you need full recovery from a backup. Otherwise you may only need to do the next part.)
Download and install MTK drivers. (Link)
Load scatter file and preloader (Link) in spflashtool. Press Ctrl Alt V , then go to Window and select "write memory". In file path select "user", in begin address put 0x0, In Region select the partition named "EMMC_USER". Hit Write memory. After that plug in the usb cable (connected to usb1 port). If the device is not detected, you need to power it on. If still not detected then you might need to short the two test points (see picture) (without power this time) and then plug in the usb cable. Remove the short when write process starts. Check if the issue is fixed. If its not fixed, then do the same to write boot2 and boot1 partitions as well. You may need to download Boot_1 specific to your original firmware from the link above.
Uploading Firmware (full or parts) via flashtool:
If you are uploading the firmware available in parts, you only need to upload "BOOTIMG" and "ANDROID" (SYSTEM).
You may also need to flash "RECOVERY". Remember to uncheck the preloader. Here is a nice instructions file. (Link) (thanks Maxkir)
There is more info and firmwares to chose from at 4pda forum.
Update / Upgrade Procedure via USB flash drive:
Copy the zip file (do not extract) to usb drive or microSD card, (formatted by SD Card Formatter). Connect to usb port 1 or 2. Go to Car Settings, System info. Click Android Upgrade.
--OR--
Extract the zip into a folder named XYAUTOUPG into the flash drive or microSD card, connect to usb port 1 or 2 and then reboot. Upgrade should start automatically. You might need to try with different USB drives or sd cards. For some reason this only works with certain usb and cards.
I hope it helps. (donations are always welcome )
MCU Upgrade Procedure via USB flash drive:
Extract the mcu file into flash drive or microSD card. Connect to usb port 1 or 2. Go into system info and update mcu.
Make a Full Backup/Memory Dump:
Open SPFlashtool, Select Memory Test Tab, Select only RAM Test (uncheck the rest), push start, and connect the unit. Save the information appeared, in a text file for later. (Read above "Memory dump procedure" for the usb connection setup).
Now go to ReadBack Tab, Double click on empty space next to tick mark, Select a folder where you want to store the dump file, and Type a name for the dump file you are going to creat, (ie. Boot_1, Boot_2, USER). Click Save. In next window "Readback block start address", select the region you want to make backup of (ie. EMMC_BOOT_1, EMMC_BOOT_2, EMMC_USER).
Start address is 0x0000000000000000
Length copy and paste from the text file you created earlier.
typically for Boot_1 and 2 the length is 0x0000000000400000
and for USER (16GB models) the length is 0x00000003a8000000
Click OK.
Now click on Readback and then connect the unit via usb cable. and Read process will start.
Do the same to make backup of all three partions. USER will take long time because its the largest partition.

All relevant info about ROMs and flashing you can find in top header of this russian forum.
Look at the spoilers in the gray header layer and use Google translate to understand what is written there.
There are 3 ROM versions for the 8227L based head units. I downloaded and installed the oldest of the 3 (rooted and TWRP IMG included). Copy all files from the RAR to a flashdrive in root folder.
Turn off the head unit.
Connect the flashdrive to USB 1 slot of the head unit.
Turn on the the head unit.
The install process starts immediately after turning on.
It takes about 10 minutes.
When install process is ready, turn off the head unit.
Detach the flashdrive.
Turn on the head unit and it will boot with factory settings like a new device....
Note that there are also ROMs for flashing wit MTC flash tool downloadable.
But the versions for installing from USB sticks ( po russki - dla flashky) are more comfortable to install and I don't own a Windows pc. So this variant was my favorite method...
Regards and good luck...
Edit: if your unRAR program asks for a password for unpacking the RAR file, then use Eazy unRAR app from Playstore on your Android device - it ignores password lock in RAR file ...
Edit2: the 5th gray spoiler in the top header of the Russian forum hosts the links to the ROM RAR files...
The USB flash drive method didn't work for me, Device doesn't detect USB while booting up. I tried everything, connecting the test points, pushing reset button etc. to no avail.
SP flash tool does seem to work, I have tried uploading several available roms, only these three uploaded successfully,

All relevant info about ROMs and flashing you can find in top header of this russian forum.
Look at the spoilers in the gray header layer and use Google translate to understand what is written there.
There are 3 ROM versions for the 8227L based head units. I downloaded and installed the oldest of the 3 (rooted and TWRP IMG included). Copy all files from the RAR to a flashdrive in root folder.
Turn off the head unit.
Connect the flashdrive to USB 1 slot of the head unit.
Turn on the the head unit.
The install process starts immediately after turning on.
It takes about 10 minutes.
When install process is ready, turn off the head unit.
Detach the flashdrive.
Turn on the head unit and it will boot with factory settings like a new device....
Note that there are also ROMs for flashing wit MTC flash tool downloadable.
But the versions for installing from USB sticks ( po russki - dla flashky) are more comfortable to install and I don't own a Windows pc. So this variant was my favorite method...
Regards and good luck...
Edit: if your unRAR program asks for a password for unpacking the RAR file, then use Eazy unRAR app from Playstore on your Android device - it ignores password lock in RAR file ...
Edit2: the 5th gray spoiler in the top header of the Russian forum hosts the links to the ROM RAR files...

No idea, what else you can try
If you can connect a PC to headunit and flashed a ROM with TWRP, may be you can use adb reboot recovery and clear data and cache via TWRP?
Hope you find a solution to boot your HU...

The USB flash drive method didn't work for me, Device doesn't detect USB while booting up. I tried everything, connecting the test points, pushing reset button etc. to no avail.
SP flash tool does seem to work, I have tried uploading several available roms, only these three uploaded successfully,

No luck with adb either.
seems like my only option is if I could get the exact ROM for this device and flash it. The seller was less than helpful, so Aliexpress refunded me in full.

Received firmware files from seller, but its probably the update files, not the complete firmware. Unable to flash it via sp flash tool. (copy and paste the whole link until the .zip part)
http://download.seicane.com/doc/80/H5 Android 8.1 updated file.zip
Any ideas ???? my device is a brick at the moment, and doesn't recognise usb flash drive for updating.
Fixed.:victory:
Check the first post for detail.
So you flashed via sd card or flashtool?

Thanks for that, wow the memory dump is massive more than 4Gb! Did you use format and download or just download in the Flash tool? Do you know the files the scatter file took from the memory dump? So, you didn't use any files from the first download where you took the scatter file from? I'm still having a problem connecting to my PC may have to use the hardware forced (testpoint) method!
You need usb male to male cable, attach it to usb1 on the device. but not yet connect to pc. Run the sp flash tool. and select the correct scatter file. Then run which ever function you need. after that connect the usb cable to pc while connecting these two test points (picture) with a small piece of wire to each other. After it is recognised and operation starts, you can release the jumper wire.

Thanks, when I use the scatter file from the first download and put it with the files in the second download it only picks up the preloader file nothing else?
Hi, Scatter file is only needed to make sp flash tool recognise the partition table on the device. no need to download anything via scatter file. press Ctrl Alt V , then go to Window and select "write memory". Set start address to 0x00 Use this to write Boot_1 , Boot_2 and User, to EMMC_Boot_1, EMMC_Boot_2 and EMMC_User respectivly. thats it.
I hope it helps.

Help for flash with USB-Key YT9216B Chinese Android Head Unit

Good morning all.
I'm trying to flash my firmware but it doesn't work.
I tried more configuration for the usb reader: reader or host but the result is the same.
I reboot with the small reset button and a wooden pick.
here are the pictures of my process:
1: I format the USB-KEY
2: I choose the Firmware and EXTRACT in the USB-KEY
3: I take out the XYAUTO-UPDATE.bin file from the XYAUTOPG file and I put it in the ROOT of USB-KEY.
4: I put the USB-KEY in the reader and I do RESET with the wooden pick.
I get the rebbot but no change to programming the HU and the HU turns on normally then
sets the time ...
5: when I place my USB-KEY in my PC I check the USB-KEY and I see the files "LOST.DIR and Android"?
Can you help me please
I try to redo the firmware of this thread:
https://forum.xda-developers.com/android-auto/android-head-units/everything-yt9216b-t4007063
My pc does not recognize the HU when I connect the usb cable A-A, I don't know why, nothing happens,
then I cannot do the procedure indicated with ATC Flash-tool...
I d'ont remember if there is an USB 4 pin or an USB 6 pin behind the unit, does it matter?
I've been looking for a week on this forum as well as the Russian forum and I can't find the solution

You just have to boot the os with the usb stick(ota zip file and XYAUTO-UPDATE.bin) inserted. It will reboot spontaneously and install the new firmware. You don't have to use the reset.
I wanted to use the pc with spflashtool to upgrade the firmware to android go 9. I don't know if this is possible, cause my device only has 1 gb of ram. I do know if you want to use spflashtool(under download options select both checksums), you have to set it on download, connect the usb and press the reset button. it will start flashing at boot of the device.
A lot of parsing errors, so time for upgrading the firmware.
*edit: systempartition of android 8.1 go seems to be 1.5GB, so the 1200MB of android 9.1 go could very well fit with the 'Download only'-mode.
*edit2: to answer the original poster, there is this topic with a rooted, twrp real android 8.1 rom.
The way to install it is to use spflashtool, connect it through usb with the radio and flash the new rom. So first you have to install the usb drivers(driving signing turned off), then you have to run spflashtool, pick the scatterfile from the rom, and either choose 'wipe and download' or 'upgrade'. Then you select download, the spflashtool vagues, then you have to connect the usb with the radio usb. It should install without the radio turning on. So the radio can be left without power connection.
Just, there might be differences between the yt9216b and yt9216c revisions.

Junsun V1/Pro Megathread

This thread is consolidating all the information of Junsun V1 and V1Pro devices scattered in the Android Head-Units forum. I want to write and extend this to make it easier for new people. It's sometimes difficult to find the right information.
Warning: Some of these commands are altering the system. If something goes wrong you can brick your device. Be sure you know what you're doing. I'm not responsible for any damages!
General Other Threads​Junsun V1​Junsun V1 Pro​Junsun V1 Pro Firmware (8259)​Junsun V1 Pro Firmware (8227L)​Junsun V1 (8667Q)​Firmware​Updating the device firmware​Junsun V1 Pro firmware files​Root​ADB connection​Root with Magisk​Writable System​
Updating Firmware​Preparation​
USB drive formatted as FAT32
Files for update (*.bin, *.upd) need to be in the root directory of the USB drive
Starting the Update​The update should start automatically when the USB drive is plugged in. A pop-up appears that says that an update will start. After a few seconds the device will reboot and install the update.
If this doesn't work, plug in the USB stick and restart the device with a needle in the reset button. When the device starts up move one finger on the touchscreen around and wait for a green detected message at the top of the screen. The update will start.
Problem solving​I don't have a *.upd file
That is OK, the file does mot contain any information. Just create a new empty file and rename it like the *.bin file. As example, if you have a 8259.bin create a 8259.upd file.
The device doesn't recognize my USB thumb drive
There are 2 USB connectors on the back of the device. If one does not work, try the other. Make sure your thumb drive is formatted as FAT32.
Firmware Files​This list is made by taking links from different firmware threads (found in first post). Every entry has a link to the original posts. Please be careful when flashing, the files need to match the correct CPU and screen resolution. If you have files for the normal V1 or different screen resolutions you can send me a PM.

Factory Reset​Settings -> Car Infotainment -> About Device -> Settings Icon -> Code 8878 -> Erase all Content
ADB Connection​Preparation​
Activate Developer options. You have to click a few times on the build number until you are a developer: Settings -> System -> About Car -> Build number
Activate USB debugging. Settings -> System -> Developer options -> USB debugging
Use the 4-pin USB connection on the back of the device. Connect with a USB A <-> USB A cable. My device had a female Mini USB adapter for using a Mini USB cable.
Connect​Use adb to connect to the device
Bash:
adb shell
Problem solving​ADB can't find any devices
It could be that the ADB connection with the device is not working. This means that the corresponding option is not set. This can be done temporary or permanent.
Temporary Connection
To make the connection with adb work temporary we can change the USB setting of the device. To do that we need to set Settings -> USB Preferences -> USB controlled by -> This device. No it should be possible to connect via ADB. The connection is temporary, because after a reboot it is gone and has to be set again.​
Permanent Connection
We can enable the connection permanently by changing a value in the secret menu. Go to Settings -> About Device -> Cogwheel (top right) -> Code 8878 -> Others -> USB2 Debug -> Enable​
Can't find USB Preferences
Go to Settings and click the search icon in top right corner. Type in usb and then click USB controlled by.
Root​Create boot.img​Connect via adb to the device and find the location of the boot partition. The star '*' has to be replaced according to your device. For my Junsun V1Pro it is bootdevice. In the next step we will create a copy of the boot partition. Please be careful with dd command. It will overwrite wrong files or partitions if you do a mistake.
Bash:
adb shell
su @#zxcvbnmasdfghjklqwertyuiop1234567890,.
ls -l /dev/block/platform/*/by-name/
dd if=/dev/block/platform/*/by-name/boot of=/sdcard/boot.img
Patch boot.img​Install Magisk apk on your device. I used Magisk v23.0 from here: https://github.com/topjohnwu/Magisk
Open the app and click on top right Install button
Then click next and choose Select and Patch File
Select your boot.img and let Magisk patch it.
Copy the new created file to your computer. The filename will be similar to magisk_patched_23000_***_boot.img
Bash:
adb pull /sdcard/magisk_patched_boot.img <older_on_your_computer>
Flash magisk_patched_boot.img​
Bash:
adb reboot bootloader
fastboot flash boot magisk_patched_boot.img
fastboot reboot
Writable System​To make the system writable we need to remount the partitions.
Bash:
adb shell
su @#zxcvbnmasdfghjklqwertyuiop1234567890,.
remount
Now we need to reconnect and then we can write to the system (i.e. copy a file)
Bash:
adb shell
cp /sdcard/myapp.apk /system/app

Hey all, I need help with my junsun v1 pro 4gb +64gb-mtk8259- I just had it installed and everything works except Bluetooth. I can make calls from unit and or my cell phone. Apparently the people I call can hear me but I can't hear them. On occasion as it dialing I hear the ringing for a second then it cuts out. Is this a hardware issue, install issue, or something I need to change in secret menu?? I've reached out to junsun with no luck. I fixed the issue with the swc thanks to this forum!! Hoping someone can help me. Car is chrysler 300c and phone is samsung galaxy note 20.

Hi, I have the same problem, if you have found a solution to the problem please share it with me! Thanks!
I am trying to mess with the secret menu. Like bt sync type, volume, three is various options in there related to Bluetooth just don't want to screw it up worse. Hopefully someone can shed some light cuz if not I'm returning it. I'll have to pay to take it out....ughh...I love the look though, if not I would just get pioneer but it don't look stock like this
So I Brought it back to my installer and he fixed it. Apparently in my car the speaker inputs were reversed, that why I couldn't hear anyone through speakers. He told me some cars with 6 plus speakers have this problem when installing these type of units. Loving the unit now that's its all fixed.
Hello
I have Junsun V1 pro 4/64g and my unit is hanging on Google boot logo (Android 9).
Does some one know how to get to recovery to do wipe cash / do factory reset?
Thanks
I have the junsun v1 1gb, it does not enter the google play services.
I would like you to provide me with a ROOM image to update or factory reset.
Thanks!

I'm actually also looking for a way how to boot into the recovery. Haven't found one at the moment.
For your problem you could try and flash an update (or same version again). Description is in this thread.
Hi
Unfortunately updates are also not booting / updating while reseting. Plugging USB pendrive with update files to second USB port and against resting button still can't manage to update - radio is botting "normally" and ends up with bootloop
Try both USB ports.
Plug the drive in turn the device on and then move a finger on the touchscreen. I do a left right movement. If that doesn't work you will need to do it with the mtk tools and a scatter file.
Hi!! Are there any way to disable calls from SIM card ? Thanks
Hi, I purchased the Junsun V1 pro 6gb/128gb and am pretty happy with it. All the important things connected and worked straight away which was grand. One thing I wanted to check is the battery draining problem and the cutting of the 2 wires to prevent this. I found the Junsun diagram and on there it seems it's the red and orange wires (that "look" to run from the main black block to the black power block for the head unit). The query I have is those wires on my loom run from the canbus white block to the black power block in the head unit. Pictures attached to hopefully show this a bit better. Excuse the terminology Has anyone had any experience with this at all? TIA
Hi Everyone,
Can someone please help me how to factory reset code or the new firmware my Junsun v1 pro 9 inch 8G + 128 GB Radio chip MS98. i tried 8888 or 8878 but i can see no factory reset only factory setting.
thank you advance.
Hey does anyone know how to completey reset the AutoLink app? I tried disabling and enabling again but. Nothing works. I just want to get ride of Android auto activated from AutoLink.

I have the 6gb, not sure what chip. When you go into the menu after code 8878 it should say on the right in the middle "Erase All" I think. Then it asks you if you want to factory reset.
