Ohhh, no problem! Everyone started like this (me too) :D

This is your latest "UI02 fimware family": 8667Q军灿UI02-国外-1280x720_v48_20231201.zip

This is the newest, with 3D program, but it's a different "UI03 firmware family": 8667Q军灿UI03-车模--1280x720_v5_20240113.zip Please, read my post about this firmware HERE! ;)

[Android Head-Units] Gator677:
Hello gduck, where the v5 firmware was provided from? Because my seller (Junsun Official Store) gives me a link to v48 only, as the link to the latest version I've asked him. I even asked him about fw v5, but they still gave me a link to v48....

I've head unit V1 with board spm8667p1_64, platform mt6768, updated to fw v43
[Android Head-Units] gduck:
Hi! It arrived via the "usual channel": it was shared by a forum member :)

Interesting,

- last month, my friend ordered from the seller JUSUN France: the firmware is v5.

- last month, another forum members also ordered form JUNSUN. v39 or v48...

Maybe, these are older productions?

I reported the CAN BUG (open door) of the v5 to JUNSUN France, they thanked me, but officially they only send v48.
[Android Head-Units] brombol123:
I updated the system with version 48. Everything went well but it didn't solve my problem, I can't increase the brightness of the device. When I enter the settings screen it doesn't let me change the values. Thanks again for the help
[Android Head-Units] gduck:
Use Android Settings/Display menu ;)
[Android Head-Units] brombol123:
It's already at its maximum
[Android Head-Units] Gator677:
ok, thanks for info. Will ty to update to v5 soon
[Android Head-Units] wybitny2:
There is a code for such things, but resetting doesn't restore anything, so be careful. You can manually increase the brightness, but you have to do it carefully because at night it can also be a bit brighter than when there is sunlight. 1616 This is a code for colors and brightness, I wouldn't touch colors
[Android Head-Units] gduck:
So, you already reached the maximum ;)
[Android Head-Units] brombol123:
yes, but it's not enough for me. before I had an old model in my car and in the secret menu I could change the brightness parameters. ok, I'll keep it like this. Thank you all the same

Good morning, I'm new here and sorry but I used the translator because my English is not very good. I bought Junsun V1 Plus 2G 32G on April 2 and when I installed it it gave me the following errors and Junsun does not answer my messages. Can you help me? Do I have something to update? The photos are the current firmware, the radio failure, the video out failure, and the can bus failure. Thank you so much
[Android Head-Units] gduck:
You have the latest (public) firmware version ;)

a "basic settings Manual" ;) An another good manual! (not JUNSUN, but usable!)

About radio:

Please check this: Settings/Car Infotaintment/About device/gear icon with code 8878 (BE CAREFUL!!!)

Check the Radio settings, for example, this is my V1 Plus settings:

About video out:

Check you cable connections! (manual attached) Please, always connect the BACK video cable (connector 4)! Because, there are two cables on it, the wifi and bluetooth antenna!

About CAN:

The CAN bus functions are unfortunately not 100%. as far as I can see, it works, but not everything, and I also found a bug in this firmware version. Does the open door display in the middle of the screen work for you?

What is the exact type of your car and CAN adapter?
[Android Head-Units] sebaes:
Hi Guys,

I'm about to update the firmware of my unit but I don't remember if I must copy on my USB key :

- only the file 8667.bin

OR

- the two files 8667.bin and 8667.upd

Can someone help? :)

Thanks a lot

Sebastian
[Android Head-Units] gduck:
Both files are needed!

8667.upd: this is the file the software looks for, so it recognizes that there is an update file. And this file contains the checksum of the bin file

8667.bin: this is the firmware
[Android Head-Units] sebaes:
Allright, let's go with the 2 files, then !

Thanks a lot for the support mate!
[Android Head-Units] wybitny2:
You talked about voice control, but I can't create an entry in build.prop. The radio has partial root and if you edit the entry I think it can be created. I think build.prop from an older processor might help, but I can't create entries because I don't have that knowledge. I don't have anyone who would help me or have knowledge. I use the Termux application. To have a partial rot and manage entries in build.prop, just type su @#zxcvbnmasdfghjklqwertyuiop1234567890,. I use this to turn off Duraspeed. I don't know if this entry is missing, Mediatek Helio p65 has three partitions, maybe this entry must be in one of the partitions.

Does anybody know how to do a full factory reset on the unit, 8g 128r
[Android Head-Units] HockeyFever:
I have the option I also turned up my brightness a lot more than with the stereo originally let me do
[Android Head-Units] HockeyFever:
Also does anybody have the same problem on the full- touch screen on the left side about a half inch there is no touch, tried doing the five finger origin touch keep saying 1024 x 600 I can't change it to 1280 x 720
[Android Head-Units] wybitny2:
Someone has to send you the 8878 code settings, you have to restore them from the file and then everything will be fine. There are disadvantages because then the settings of the person who sent it to you will be restored, but the radio will work as it should. Maybe uploading the software with this resolution will also help you. Someone here also had a similar problem, it was due to the incorrectly loaded MCU, nothing helped but replacing the settings files in code 8878
[Android Head-Units] wybitny2:
Code 8878, click as shown in the picture
[Android Head-Units] gduck:
Full factory reset is a VERY VERY VERY BAD idea! Why do you want to do that?!

Hello i put (8667Q军灿UI03-车模--1280x720_v5_20240113.zip) somewhat everything seems fine except the touch and maybe some little things, but now I want to put this zip file (8667Q军灿UI02-国外-VHD720x1280_v13_20220510.zip) I get into recovery mode but it doesn't upgrade or do anything just restarts and go to the main interface does anybody know how I can force this file, I realize that in the original file it started with, vhd 720 x 1280 not 1280 x 720 if that would make a difference.
[Android Head-Units] gduck:
Hi!

Try this:

1. Use a FAT32 USB drive for the firmware files. (try with different USB drive if update not working)

2. Extract 8667Q军灿UI02-国外-VHD720x1280_v13_20220510.zip. You should two files on the USB drive: 8667.upd and 8667.bin

3. Connet USB drive to the 4 pin USB!

4. If update not starting:

RESTART the HU, either from the car's power supply or from the RESET button

- touch the screen with five fingers continuously

OR

- swipe your fingers on the screen maniacally
[Android Head-Units] gduck:
Hi!

Sorry, but the V3 is not an exact imformation. :( If you have VW T5 Multivan 2005, why using CAN code 295 (Audi)? Did the seller tell you? In order to be able to help you, we need exact information. At least the type of CAN adapter... ;) For example: HiWorld, SimpleSoft, Raise, etc...

For example this is an exact CAN adapter information:

SimpleSoft
RP5-RN-101
SW: V1.04.102BYPS
DC: 20231102
P/N: K0090

PS: Looking at your pictures, a seen this information: V3.89 102BYPS. I think, you have a SimpleSoft CAN adapter.

After the CAN adapter is working, you can install my fix (for open door warning)
[Android Head-Units] wybitny2:
If Mediatek Helio P65, nothing will happen to the radio. Navigation and one more application will be deleted
[Android Head-Units] gduck:
Are you talking about this? Based on users feedback, this makes the head unit almost unusable! DELETE ALL FACTORY SETTINGS! But, maybe I misunderstood something...
[Android Head-Units] wybitny2:
Yes, you are right, but not all radios have functions saved in volatile memory. I have tested the Mediatek Helio P65 myself more than once and nothing happens. I don't recommend doing it yourself, but when it comes to Mediatek Helio P65, I know that nothing bad will happen. You are right that you are warning, there are radios whose functions are stored in volatile memory and then there is a problem, bravo, you
[Android Head-Units] bloot:
I once did that and it just reseted it to factory defaults except for the factory menu 8878 settings, it wiped everything but unit works as always.
[Android Head-Units] gduck:
Thank you wybitny2 and bloot! ;)

I read somewhere that I can save the menu 8878 settings in MP mode. But it asks for a password. Do you know the password?
[Android Head-Units] wybitny2:
The functions of code 8878 are assigned to the MCU and nothing is reset here, you have to change the settings carefully because the problem cannot be undone.
[Android Head-Units] bloot:
I also would like to know that, I've been trying to backup my factory settings but no luck yet.
[Android Head-Units] wybitny2:
I have to check it, there was no password before

Anybody can help me? I tried installing a new bootanimation but it does not work, there was an "android" logo animation before I installed this and now there's nothing but the boot logo I setted a while ago, my bootanimation won't start.

Is something wrong that you can see in this file?

Dropbox

www.dropbox.com
[Android Head-Units] gduck:
Strange. Because the zip content it seems good... Maybe, you have problem with the 'part' folder name. In the desc.txt: part0, but the folder name is Part0. Try rename to folder to part0 (with little 'p'). Just an idea ;)

PS: and the png size is 1920x1080, not 1280x720! Resize it! ;)
[Android Head-Units] bloot:
Nice catch! Didn't notice it, will try :)

Edit

Solved!

Even after renaming folder "Part0" to "part0" bootanimation still did not show, so it turns out compress method must be set to "store" and then it worked perfectly fine (y)
[Android Head-Units] gduck:
(y)

A question: you have 38 files and 30fps. Is this only a 1 second animation?
[Android Head-Units] bloot:
I adjusted it a bit once I had it working, added some more frames and lowered the frame rate to 20, I needed to see it moving first to know what to adjust, here's the final file in case anyone is interested in it (it repeats on loop until the system boots).

Thank you so much @gduck for your work and sharing your experience. I use the firmware with ui03 (but I've not the 3d car licence 🙁) with tengshi launcher and it works flawlessly. Thank you also for let me know about Magic Earth wich is really great in pip mode ( speed limits !)

I have 2 questions:

Is it possible to launch magic earth automatically on startup ? (I have to touch the screen pip area to start it)

Is it possible to disable the color blinking icon at the bottom left of tengshi launcher ?
[Android Head-Units] gduck:
Hi, I'm not an engineer and I don't work in the LCD business :D

But, my idea is: the LCD screen and the TOUCH screen are two different layer. The LCD resolution is 1280*720 and the TOUCH screen resolution is 1024*600. But, this is only my idea ;)
[Android Head-Units] gduck:
Hi!

Yes, your CAN adapter type is SimpleSoft = (XP), then in principle you should choose from the (XP) setting.

There were 2 VWs in it:

- 122 VW MQB Platform(XP): maybe you can try it, but I think this use a newer protocol

- 240 Volkswagen(XP): have you tried this yet?

If you want to try it, but these are not in XP:

(I searched for the 'T5', but this T5 may have nothing to do with the VW T5. Someone smarter will tell you ;) )

- 93 BS M3 and T5

- 97 BLSU M3 (RZC ) and T5

- 259 BLSU (OD) and T5

Or, Maybe this CAN adapter is not right for you?
[Android Head-Units] gduck:
About 3D car license: Did you tried this? But, I one user reported, this license was expired...

"UPDATE3: JUNSUN support published the 3D app activation file: LINK. Copy the cert file to a FAT32 usbstick, insert to HU and click the gear icon. 04/2024: one user reported, this license was expired :("

About Navi start: Did you tried this settings?

8878/Others/Auto NAVI - Automatic navigation start (App selected in Settings - Car Infotainment - Navigation - File Path)

About Color blinking icon: deal with this in my free time, and I would like to increase the size of the NAVI window a little and make the other windows smaller. I think the left part is too wide. Now I'm trying to put together an Android emulator or I need an another HU that I can just develop. It's bad enough to test it in the car :)

Hi All

I bought an 8GB/256GB and installed it in a Megane 3.

I've a problem with built in MIC, other one ears me very low and noisy. Any config to improve microphone sound? I tried upgrading to 8667Q军灿UI02-国外-1280x720_v48_20231201

And some questions, somebody with a Megane 3? Can you see parking sensors in camera?

My radio turns on when I open the doors and turns off after 2 minutes from when I turn off the ignition. Can it be changed to turn on and off with the ignition?

[Android Head-Units] gduck:
Hi!

You can switch on the parking radar (a car on the top of right on the back camera picture) in the CAN settings (if it supported):

About HU switch ON/OFF: based on your comment, it seems that the HU wireing is correct. YELLOW wire FIXED 12V, RED wire IGNITON 12V. (You can check!) And the SLEEP mode settings in ON. My opinion: the timeout is your car default setting. ;) Don't worry about the 2 minutes ;)

Is there a way to prevent the reset of the radio stations when saving changes in the 8878 menu code?

The main screen icons and radio stations are allways reseted.
[Android Head-Units] bloot:
No that I'm aware of, only thing you can do to avoid it is not changing settings very often in the 8878 menu code :(

DSP settings resets too.

Hi, I bought Junsun v1 plus a week ago and I have the same problem.

No keys in recovery, no USB for flashing detected (flashboot and adb on my Debian).

Exactly, not work at all. If "USB2 debug" is disable the both USB work as host. If I want to change the mode it fails.

Anyone could help me to flash patched boot(by Magisk)?
[Android Head-Units] wybitny2:
Boot. img is not that big of a problem. in the older software it worked and there was no need to change anything in the 8878 code. Newer software and no matter what I did, I couldn't connect to the radio via wi-fi adb so I gave up on this topic. I know one thing, there are three or four switches on the board, one of them shows that it was switched, I suspect that switching this switch would give results. Only because it's about the radio and that's why I didn't try to flip that switch. I'd rather have a working radio than flip a switch and have a problem. The Chinese had to connect to the computer, but they didn't want to tell me how to do it. If I ever change the radio, I'll take the risk, but now I'm afraid what will happen if the radio still works after switching and returning the switch?. If you're not afraid, let me know what happens when you turn this switch
[Android Head-Units] rysson_:
Many of my favorites apps need root access (or work better with root), than I'm searching how to flash patched boot to get full root (get boot.img via `dd`, patched in Magisk app is already done).

About remote access, have you tried to set property and restart adbd? On root shell (`su`) of course .

setprop service.adb.tcp.port 5555
stop adbd
start adbd

I had no connection too, until I set it ones. Now I have remote adb even after restart (I don't remember if I remount to rw before).
[Android Head-Units] wybitny2:
Maybe in this software you can connect via ADB wi-fi. The software is constantly changing, so I gave up on root, especially since ui3d is obviously new.
[Android Head-Units] gduck:
Hi!

There are many options for software "repair" what is your exact problem?

About USB2 Debug: the default JUNSUN HU package contains only the USB0 and USB1 cables! If you would like use USB2 port, you should change your 6 pin USB cable to this cable! In this way you will have a USB2 port and you can use the USB2 Debug option. ;)

Note: in default, the USB2 port only provides power, it is ONLY good for charging!

You can find the MT6768 scatter file HERE!

You can find some useful info, HERE!

( Thank you for Rradistt! ;) )
[Android Head-Units] gduck:
Unfortunately I don't have much time, currently I'm only planning to modify the Tengshi launcher.

You can choose from hundreds of different 3rd party launcher themes ;)

For example:

- Infinite Launcher ILauncher Homepage from Dofun. You can buy one month license (trying it) here Dofun shop.

- Dudu launcher. Unfotunately most of its versions are only in Chinese. Only this version is English: DuduLauncherPro 1.001008

- AGAMA Car Launcher

- VIVID Car Launcher

- CarWebGuru Car Launcher

- Car Launcher

etc.
[Android Head-Units] bloot:
Which are the firmware versions that don't allow adb over Wi-Fi? I can confirm it's possible on V39 and V46.
[Android Head-Units] rysson_:
Thank you very much! I

I get 6-pin cable. But wait, is there (on pins 3 & 6) power or USB2 data?

I can move pins from 4,5 to 3,6 and check during waiting for 6-pin cable.

I'll read of course, I'm still reading, my mind is too small ;-)

I have a few „problems”

- after 9191 (random codes) I have unregistered device now

- I want to use magisk to get full root

- I use to use many apps (like backups, f-droids) they need root

- I've read that I could use GSM with SMS na calls, not only for Internet with root

- I want to replace same HU software like MODE switcher

- I want to add can-bus even if my steering well's buttons uses resistors , to see eg. opened doors

- etc.

First need repair, rest of them flashing boot.img, if I'm not wrong. I can not flashing now, I can't see HU in my PC at all.
[Android Head-Units] gduck:
Of course, pin 3 & 6 are USB data, BUT:

- During normal mode, these are DISABLED. So, in this case the USB2 is only "power port".

- During USB2 Debug mode, these are ENABLED.

This is the 6pin USB port pinout, you can move wire 4->6 and 5->3:

About 9191 problem (for everyone: NEVER USE the 9191 code!!!!):

Did you tried solve the problem with one of them License.dat? (Extract to License.dat to an USB drive and connect to the HU. Internet connection is needed for the activation!)
[Android Head-Units] rysson_:
You save my live. Tomorrow I'll check everything.

I used one licence file, but it fails, google says the popup message was "incorrect file".

I will NEVER use this code again.

I agree, nobody should.
[Android Head-Units] rysson_:
OK, next day, next challenges :)

Thank you very much again. I had found another license but without success. Your first licence is ok, now my device is registered.

BTW. there is interesting file format, is seems like base64 and number. Decoded part looks like another b64 and date-time (e.g. s7XS17TvI0NZSUQ=#20210520133937#) and decoded part is ״#CYID. I'm curious if it would be possible to find this data in HU.

About USB2 – I changed pins and it seems that those pins are not connected or there is another protocol (serial?). My lsusb shows nothing, dmesg shows errors (Device not responding to setup address, device descriptor read/64, error -71).
[Android Head-Units] bloot:
That firmware is for the 8259 plattform not the 8667.

Hello

I have just bought a Junsun V1 Plus Radio 8/256 and the firmware is: 8667Q军灿UI02-国外-1280x720_v48_20231201 X=1280 Y=720

The seller says it is the latest version, but what I think is that he doesn't want to send me updates. The radio has UI2 and the firmware is from December 2023.

Is really the last one? UI2?

Thank you
[Android Head-Units] gduck:
Hi!

In the UI02 "JUNSUN firmware family", the v48 is the latest public version. This is contains UI03 and UI04 THEMES. Please, read my old post HERE ;)

The newly made devices (I think, some users was reported it) arrive with the newer firmware. But without 3D Carmodel program activation, there is a black square on the display. I think that's why they don't send sellers this to anyone, because then they would also need a license. Please, read my old post HERE!
