Thanks but it doesn't work either.

I've been told this is mine.

How do I connect it?

Hi Rradistt!

Can you help me? I tried to connect, but not working. :(

- I used 6pin Y cable with USB2 port

- I enabled USB2 Debug

- I installed Mediatek USB VCOM Preloaded driver from HERE

But the USB device is always: usb descriptor failed code 43

Do you have any idea? Can you share your experiences?

THANK YOU!
[Android Head-Units] gduck:
Hi!

Ahhh... maybe our USB data wires are connected incorrectly? I will try tomorrow!

This is Rradistt's cable. Pin3 is green and Pin6 is white

This is my cable. Pin3 is white and Pin6 is green
[Android Head-Units] Rradistt:
It is necessary to select usb 2 debug by code 8878 on another tab and restart the radio, then the connector will work strictly as in my photo, the white one has swapped places with the green one. On the new firmware, when you connect USB debug, different nonsense happens
[Android Head-Units] gduck:
Hi! THANK YOU!

But, unfortunately it still doesn't work, the SP Flash Tool does not see the HU. It seems something still missing. :(

What I did: I changed the green and white wire in the USB2 port. The communication problem was gone. :)

My experiences:

- If 8878/Others/USB2 Debug is DISABLED: USB0 and USB1 ports are working with data connection, USB2 is working only a power source.

- If 8878/Others/USB2 Debug is ENABLED: USB0 and USB1 ports are DISABLED and USB2 port is ENABLED. In fact, the HU works like an Android phone

If Android (developer settings) USB Debug is DISABLED, you can connect to HU and access the media files, etc.

Device: FF_866X USB\VID_0E8D&PID_2008&REV_0404

If Android (developer settings) USB Debug is ENABLED, you can connect with ADB shell

Device: spm8667p1_64 USB\VID_0E8D&PID_201C\0123456789ABCDEF

Do you have any idea what is missing for USB2 port to get to this state? ( Mediatek Preloader USB VCOM )

Device: Mediatek Preloader USB VCOM (Android) USB\VID_0E8D&PID_2000
[Android Head-Units] Rradistt:
That's right, we enable USB debugging in the developer settings, after which it should be visible on the PC. To be honest, I'm not lying, and I achieved all my goals thanks to the experience of flashing MTK devices by copying a full 256 GB ROM using SPFlashTool, and then processed MTK's WVR by partitioning it. Use the search for instructions on how to perform a full data copy on the SPFlashTool Riedback tab when we restart the radio using the restart command from the terminal. All manipulations were performed in Windows 10/64 bit. It is very difficult for me to explain myself in English, even through an interpreter.
[Android Head-Units] gduck:
Thank you for your extended help again! Don't worry about the translations ;)

Did your cable originally received with this wiring (Pin3 green and Pin6 white) or did you also swap the two wires?

So, I seen in your picture, you used adb shell.

Do you remember?

Do you used "adb reboot" or "adb shell reboot" in MTK's WVR ?

- in this time, has SP flashtool already started?

- after HU restarted, do you seen the HU in the SP flashtool?

THANK YOU!

Hi, finally the picture is up on the boot logo! I have to use 1920 x 720 BMP file. What a hard guess!
[Android Head-Units] gduck:

I should use "Reboot in Bootloader mode" ;)
[Android Head-Units] sebaes:
Hi guys,

I tried to update my unit from version 37 to 53 but this is the first time the update does not work....

The screen is blocked on "FASTBOOT MODE" ; I'm lost, can someone help me ?

Thank you guys

Sebastian
[Android Head-Units] bloot:
You should be able to exit fastboot mode just by switching off iginition and then the HU should start normally
[Android Head-Units] sebaes:
Yes you are right, it works now !

Thanks a lot !
[Android Head-Units] rysson_:
You are awesome! It's working, thank a lot!

Now I have full rooted device, flashed with magisk. I had to remove old su:

[Android Head-Units] Rradistt:
HELLO!!!

By trial and error, the contacts of the E connector were replaced according to the scheme from 3 to 6, I took the cable from the kit and assembled one of the two, then found such an option on Aliexpress and, upon receipt, swapped the contacts from 3 to 6, turned on usb2 debug and connected the connected radio receiver to the computer on which it was successfully identified, and the drivers are installed. It's one thing to download a dump, another to use it, unfortunately, no program has unpacked the image correctly. radio engineering research was suspended due to the inconvenient removal of the head unit and the lack of a laptop to work in the atomobile
[Android Head-Units] Rradistt:

[Android Head-Units] starandroid:
Hi, I downloaded the Logos from this page, I uploaded the folder to the main directory. But going into the secret menu - the search lens finds nothing. I have a second question to ask. What is the difference between the v34 firmware and the v48 version. my car radio is 6 giga ram + 128 storage. I guess this firmware is fine. Finally I wanted to ask if you have the cooling fan app. Thank you!
[Android Head-Units] gduck:
Hi!

The cooling FAN app is built in the firmware!

In the MainUI:

- images for fan app "display"

- Enable/disable fan app feature

strings.xml
<string name="support_cpu_fan">1</string>

The programs in the newer firmware are newer. There is usually a repair some bug in it as well. It never has an Android security level fix!

( Did you download v48? )

If you don't see the image, the logo file format is wrong! (Logo file resolution is important! It is the same as your screen resolution.) Please share the following information with us. ;) use code: 160

Please, check the RAM size. use code: 1111 ( load monitoring )

I'm curious, because so far everyone has reported that it only has 4GB... :(

THANK YOU!
[Android Head-Units] starandroid:
Meanwhile, thanks for the reply. Junsun made me update to the v34 version and I no longer had several apps. Fan -OBD- FM- and others. I didn't understand how to control the Ram. Regarding the boot logo, where do I put the folder? Il mio firmware è quello che vedi nella immagine.
[Android Head-Units] gduck:
About boot logo: Check your logo file resolution. If not 1280x720, please resite it! Than

- copy the logo file to an USB drive root folder

- connect the USB drive to your HU

- use code 5678

- than use the SERCH button ;)

About Fan app: ENABLE in the FACTORY SETTINGS! Video

About missing apps: I attached some originally "built in" apps ;)

If the FM radio does not work, the setting in the FACTORY MENU has been lost ( I think... similar to the FAN problem )

About RAM size: just use 1111 (instead of 160). Than load monitoring will display your RAM size too. (but this is not so important, I just curious. )
[Android Head-Units] starandroid:
thanks for all, I try again for boot logo. Resolution is right, 1280x720 but I don't know why search button don't find nothing.

How many code are in the secret menu? Is there a list?
[Android Head-Units] mitko9922:
Hi, thanks for sharing the information, I wanted to ask does the FAN also activate the FAN app and where does the FAN connect to head to be commanded from the app, thanks in advance
[Android Head-Units] starandroid:
I see your video. Not have FAN option in Factory menu. Why'??? What firmware have you?
[Android Head-Units] gduck:
Fan option: you can find it in 8878/Others menu. See the video ;)
[Android Head-Units] starandroid:
I see the video. In my factory menu 8878/ others cannot the voice fan!
[Android Head-Units] gduck:
Can you share a picture (8878/Others)? ;) Your firmware version is v34 and you have V1 Plus 6/128. Am I right?
[Android Head-Units] starandroid:
yes right! Trust me I don't have the Fan option to enable!
[Android Head-Units] mitjama:
Do other have no issues with Bluetooth calls (no sound, freezing)? Any thoughts?

Clearing the storage didn’t help in my case. Alre there some factory setting that have to be set/changet for this to work properly?

It did work before upgrading from v39.

This really is annoying.
[Android Head-Units] SteeveGr:
You could go back to V39 to see what happens after FW downgrade.

I also have 6/128 V39 and i decided to stay there. I did no FW update. Everything is working fine.

The only problem i have is that other people say can't hear me very well, actually noisy and bad, and this happens only because the mic hole is hiding behind the frame. An external mic could solve this.
[Android Head-Units] gduck:
Strange... My opinion, try to update v39
[Android Head-Units] starandroid:
v39? Not v48? I dont have v39!
[Android Head-Units] SteeveGr:
As you said it worked before the upgrade. So, go back to 39.

I got it from this post #1,508 (thanks to gduck), but the link has expired.

I uploaded again to WeTransfer, and the file will be available for 7 days: 8667Q军灿UI02-国外-1280x720_v39_20230712
[Android Head-Units] gduck:
v39 is a good, stable version. Try first ;)
[Android Head-Units] Myst3t:
Ok short feed back :

3d car license work ! Thank you for this. But anyway I prefer the alternative launcher with pip window.

Auto navi was not the good choice for me because it launches earth magic in full screen, and I suspect it launch it too early before initialisation of GPS so it was frozen. I disabled it and prefer to touch the screen on time on each startup.
[Android Head-Units] starandroid:
many thanks for the file. I have v34 and try this v39 🙏

V39 works well. Thanks! But Logo I cannot change and update. I put folder logo in Usb but nothing...
[Android Head-Units] bloot:
Just put it in the root folder of the USB or the internal storage, not inside any folder. Image MUST be 1280x720 bmp or png.

Tell me how to remove the lower parking lines
[Android Head-Units] gduck:
Is the FAN working with v39?

Hi!

Upper parking lines controlled by the HU.

Lower parking lines controlled by the CAMERA.

What camera do you have?

- factory?: no idea

- or bought?: usually you have to cut a small cable at the camera. It is included in the description of the camera!
[Android Head-Units] Firmanudin:
do you have android head firmware type f912 mainboard ver 0.5 2?
[Android Head-Units] starandroid:
for the moment I only had the Junsun security app which crashed. Today I heard from the Junsun technicians who were alarmed because in their opinion the firmware version they had given me was the right one and that other firmware cannot be installed. Too bad it was giving me problems with the car audio fan. I'll send you their message.

"our machine is different from your friend's. Our machines are upgraded very quickly. Even if they are exactly the same version, there may be differences. What's more, your versions are different. How is this comparable? Every time you update the firmware, applications and data will be lost. This is normal, this is not a firmware error, a firmware error you cannot update at all. It is recommended that you do not update it in the future. Updating is a time-consuming and troublesome thing for you. You have so many questions! ! !

Yes now working!

Junsun technicians were alarmed. they say I don't have to flash other firmware. Too bad the fan doesn't work with their firmware and they wanted to send another Fan apk. I still have problems with the logos. he doesn't see them, he doesn't find them.
[Android Head-Units] gduck:
LOL! Don't worry about what the JUNSUN technicians say! I "translated" that message: "If you don't update, we probably won't have a problem with you because you can't screw anything up." :D

Boot logo, try this

1. Extract the pictures to the HEAD UNIT root folder!!! After extracted you should see like this:

[Android Head-Units] amanate:

The Junsun radio has a software error, when the quick start is turned on, it goes to the canbox settings or the software is installed with a quick start, the radio will not start anymore, with these procedures it is recommended to turn off the quick start
[Android Head-Units] gamer06:
And thanks for all the help.

This is the link where I bought the radio:

https://pt.aliexpress.com/item/1005..._list.0.0.43e0caa4JZ3vc4&gatewayAdapt=glo2bra

It is the 8GB RAM 128GB ROM model in black color.

I'm going to download this file and try it one more time.
[Android Head-Units] wybitny2:
Chinese manufacturers protect themselves not to download other software, so you do not get Junsun software, you have to ask for software from XONRICH. The one I sent to Ossuret, take a chance, but I think writing to a Chinese must be. You are in the wrong place for your radio.
[Android Head-Units] JhOLmeS86:
Hi, I have a Junsun V1 Pro 8 + 256, model 8667. I contacted the seller, to ask for the updated firmware. He sent me a link to the file "8667Q 军 灿 UI02- 国外 -VHD720x1280_v23_20220801", I ran the update, but I don't see any difference. I saw in the thread some photos with different graphics ... are there better firmware at the moment? I understand that it is not the last one released in chronological order! Thanks, Ignazio.
[Android Head-Units] wybitny2:
There is software with the new ui 8667Q 腾 实 UI05- 国外 -1280x720_v36_20220825, but the software does not work for me, it has errors, does not install a newer version of the one I wrote. you have to look for this software is here, only what I wrote nothing else is good
[Android Head-Units] JhOLmeS86:
Ok Thank yo

Ok thanks, I tried both firmware, and at the moment the best in my opinion is the "8667Q 军 灿 UI02- 国外 -VHD720x1280_v23_20220801".

Can I ask the owners of Junsun V1 Pro 8 + 256, model 8667 for information? Were you able to activate bluetooth tethering? I tried following some similar car stereo guides but you just can't, I wouldn't want it stuck in this specific model!

Normally there is no such option, try apps from the store hidden settings, maybe something will be there

Hello,

I have two questions.

1. I'm a little bit confused about firmware v36. @wybitny2 said in one Post this is not for junsun but for ossuret. Other said it is working. So can you please tell me if v36 is right for junsun?

2. Also in a Post of @wybitny2 i read something like this:

ro.forfan.adaptany.twidth=1280

ro.forfan.adaptany.theight=720

forfan.extscreen.twidth=1280

forfan.extscreen.theight=720

What does this mean. I understand that this is related to the Resolution. But where does this setting come from?

Best regards
[Android Head-Units] wybitny2:
This software is for Junsun 8667Q radio 腾 实 UI05- 国外 -1280x720_v36_20220825, sorry I was wrong. I had it installed, too many errors, the second thing I do not like the new ui.
[Android Head-Units] twinking:
Thank you for the answer. Can you also answer my second question about the widthband height settings?
[Android Head-Units] wybitny2:
This setting prevents the radio from starting, I don't know how to explain it to you. means the image is reversed and will not work on Junsun. ro.forfan.adaptany.twidth=1280

ro.forfan.adaptany.theight=720

forfan.extscreen.twidth=1280

forfan.extscreen.theight=720
[Android Head-Units] twinking:
Okay I understand. And where do you get These settings? Can you find them in a configuration file?
[Android Head-Units] wybitny2:
Yes, I am looking for them in the configuration peak, I want to be sure
[Android Head-Units] twinking:
Okay thank you.

Another question. When installing the Update, does this also reset the settings in the factory setting. For example the can settings and all the setting you can access via the 8878 Code?
[Android Head-Units] wybitny2:
Nothing is deleted here, with the code 8878
[Android Head-Units] twinking:
Hm, I would have like to get this All resetet. Do you know how this is possible?

I have a Problem with my Touch keys and i think this is related to the settings in the "other" Menu of the factory setting (8878). There are setting for touchX and touchY and i need the numbers that was the default.
[Android Head-Units] twinking:
Do you still have the problem? I think this is because your car never shuts down the Power from the headunit. When you disassemble it and unplug and replug the wires it should Start afterwards.
[Android Head-Units] wybitny2:
I will be in the car, I will take a photo for you, but not today, when I am in the car, this photo will appear
[Android Head-Units] gduck:
Don't worry! ;) V5 is contains a little bug related the doors warning, otherwise stable! I use this too!

v39 is "stable", because many head units came out with this software (based on forum feedback). And if you want, you can update to v39 at any time ;)

I recommended v39 to him because there was something interesting fan error with v34. In this case, it is better to update in smaller steps ;)

I think S700S app is different from S700, as others told you it's needed to update it from the settings menu on the original app that comes in your cam storage (you can share your mobile data network with your HU to update it). At least this was the case with my S700, I had to update it to have video signal.
[Android Head-Units] rysson_:
I already did the update from the app (uninstalled the app first, installed old app from the camera and upgrade from the old app). It installed version 0727_v6.1.4_overseas.

I've bought sdcard with the camera and I can find mp4 video files on the card. But I can see video in the Android (no ADAS too) nor change camera settings.

I have stupid question. Witch app should I use:

com.fvsm.camera aka HD Camera

com.ankai.cardvr aka "Name" (no Polish translation?)

something else?

Both has ADAS settings.
