I have been conversing with them in Chinese all this while since I am from Asia too. Lol

My supplier told me the engineer is looking into my usb and theme problem. Will provide update in future. Highly doubt it..

I also requested for a latest FW which she was quite reluctant, telling me to just leave it as it is since all functions are working properly. Lol

I am going to drop a bombshell to her soon that I bought an android 12 system but was given a 10 emulated to 12 system. Gonna see what she says about it.🤣🤣

Really appreciate for all the help rendered. 😊😊

Hi again, these were my experiences with my second firmware update. This time it was NOT a regular update, because Ossuret/Hipzo firmware was added to the JUNSUN V1 device. I did it because for some inexplicable reason, I really like Launchers that use PIP. And unfortunately, this is not allowed in the JUNSUN V1 firmware.

I read a warning here in the forum about the build.prop file, but in this case it WAS EXACTLY THE SAME in the two firmwares!

So, My device is a JUNSUN V1 Plus: MS94NV UK 9 inch 4G+64G.

Actual (original JUNSUN) firmware:

8667Q军灿UI02-国外-1280x720_v46_20231122.zip-Tan.zip

Target (Tengshi) firmware:

8667Q腾实UI05-国外-1280x720_v53_20230914.zip

Firmware changes:

8667Q军灿UI02-国外-1280x720_v46_20231122 X=1280 Y=720 --> 8667Q腾实UI05-国外-1280x720_v53_20230914 X=1280 Y=720

Result:

The installation went well (Note: the screen was rotated 90 degrees counterclockwise during installation. After the restart, the display was normal), everything works fine. The imported boot logo and the factory settings was remains! I have V1Plus with build in FAN. FAN application and FAN setting (factory menu) is missing. So the FAN is not working! But, the fan problem can be fixed by modifying the MAINUI.

Surprisingly, everything works fine! The Google maps runs great in the small window and other programs also works very well. :D

The Carletter version is older, 7.5.8.20230809, but I successfully updated this with version 7.7.3.20231024, which I extracted (using 7-Zip) from the JUNSUN firmware file.

Original screens:

Conclusion: this firmware can be used (at your own risk!) with JUNSUN V1, if there is no FAN in it and you want a PIP solution. And if you like this design.

I will definitely use this for a while, I will share the new comments ;)

Interesting, I have a hu which I swear has that same look (launcher), I installed the Junsun hu better because the hardware was superior, but the sofwtare of that unit was great (maybe better than Junsun's)

It is a ZQ9109 plattform if I remember correctly, 4GB of RAM and 64GB of ROM with an 8 core MTK6762

Hi, just to point something, I had similar problem with my old 8227 unit. Problem with not saving state or other things is due to system saving to a non solid disk. I had like usb drive attached all time in port , and system sometimes recognized it as system disk and saved state on it (and factory settings also which over time or sometimes failed to load). After removing USB drive unit lost all configured settings and theme state.

So , gennerally , when setting all / units state , usb drive must not be in port. That way unit is looking for available disk drive and saves state on a solid disk / internal memory. When saved and unit is booting for like several times unit succesfully saved state in memory and problem solved. Only bug in program is to repeat procedure over time as program is buggy.

Also, someone mentioned settings in factory settings REMEMBER / UNREMEMBER. REMEMBER option must be on when saving to intenal memory / disk always. Unremember option is only for reseting state after like getting some errors in overall functions, so that way android resets every time when starts.

I hope all this written helps someone with mediatek MCUs.

Hi again. Day 2 (was my last day) with the "Tengshi" firmware on my JUNSUN V1 Plus.

So, the 8667Q腾实UI05-国外-1280x720_v53_20230914 (with PIP support) is working very well on the JUNSUN V1 (8667Q). But I have JUNSUN V1 Plus with a built-in FAN. And from this firmware FAN support is missing. So, I made a small modification to my installed system, as a result the FAN was worked, but after a while, the PIP function did not work, and the home button displayed the Google map instead of the main screen. In this case, then a reboot was required to get everything working again. That's way, I changed my plan.

These were my experiences with my third firmware update. I switched back to the original JUNSUN firmware.

So, My device is a JUNSUN V1 Plus: MS94NV UK 9 inch 4G+64G.

Actual (Tengshi) firmware:

8667Q腾实UI05-国外-1280x720_v53_20230914.zip

Target (original JUNSUN) firmware:

8667Q军灿UI02-国外-1280x720_v46_20231122.zip-Tan.zip

Firmware changes:

8667Q腾实UI05-国外-1280x720_v53_20230914 X=1280 Y=720 --> 8667Q军灿UI02-国外-1280x720_v46_20231122 X=1280 Y=720

The update experience was the usual:

The installation went well (Note: the screen was rotated 90 degrees counterclockwise during installation. After the restart, the display was normal), everything works fine. The imported boot logo and the factory settings was remains!

Result:

But where is the PIP support?!:

I extracted the Tenghsi launcher (with PIP support) from the 8667Q腾实UI05-国外-1280x720_v53_20230914 firmware using 7-Zip:

After that I installed this app (on JUNSUN v46 firmware). In this case I have a secondary Laucher (as if you had installed a launcher program, for example: Agama, ILauncher etc.) The launcher works perfectly (still under testing of course ;) )

You can switch between launchers as usual:

- Laucher is the original JUNSUN launcher (with UI03 and UI04)

- Launcher3 is the launcher from the Tengshi firmware with PIP support!

The google maps is working very well in the window on the main screen:

note: I didn't create a new screenshot, but trust me ;)

My opinion: Since Android 10 supports PIP, the support depends only on Launcher!

UPDATE: for Tenghsi launcher to work properly, PIP support must be enabled in the MAINUI LINK, because without it, this launcher causes anomalies!
[Android Head-Units] M@1:
I also have a junsun v1 pro mt8667v after update firmware (the seller sanded me ) screen turn into blue screen and now no boot usb no recovery …anyone can help please???
[Android Head-Units] gduck:
Hi, try this!

Forced update:

when turning on the head unit (either from the car's power supply or from the RESET button)

- touch the screen with five fingers

OR

- swipe your fingers on the screen maniacally

After that, head unit booted from USB and the installation starting.

But in this case, you need a working firmware on the USB ;)
[Android Head-Units] yakdtai555:
So which firmware are you sticking with? Junsun v46 firmware with Tenshi Launcher3?
[Android Head-Units] gduck:
Yes. In this case you have an additional, selectable launcher with PIP support ( only ) the home screen. ( Because v46 doesn't support PIP )
[Android Head-Units] frost_theone:
- Is Tenshi Launcher 3 more intuitive than Junsun Launcher other than the PIP?

- Dont know if it's a silly question to ask.. How did u do screenshot on the Junsun headunit?

- Care to share Tenshi launcher 3?🤣🤣
[Android Head-Units] sfde:
Hi gduck, Thank you for sharing your experience! I'm newbie about Android HU. Following your process, I also extracted TengShi's Launcher and wanted to install it on my current MS94NV V46 system. However, whenever I click on the apk file, I always get a prompt saying like 'File cannot be parsed,' so I can't install it. Since I'm using the same machine and system version as yours, did you do any processing on the extracted apk file?
[Android Head-Units] Anton TNT:
Ask seller to give you another update or firmware for your specific device and resolution of device (1200x600 or 1280x780).
[Android Head-Units] Anton TNT:
Go to settings , then Google menu and find something like "allow third party software install" and check it.

In factory settings check also box that says INSTALL, it mujst be ON rather than OFF.
[Android Head-Units] gduck:
- Only the main screen ( you can see, screenshot in my post) and the application menu icons changed. Who likes what :) I interesting with PIP.

- I using this app Link

- I don't want to share part of a firmware. Please extract it, if you want! Very simple ;)
[Android Head-Units] M@1:
They send me this file and after install …
[Android Head-Units] sfde:
Hi Anton, Thank you for your suggestion. I have tried it, and it works fine for other apk files, but the launcher extracted from TengShi's firmware can not be installed. :confused:

[Android Head-Units] gduck:
My opinion this is your original firmware: 腾实UI多合一国外 = Tengshi UI all-in-one foreign

You can try this:

1. Download this firmware: https://drive.google.com/file/d/1UXcGCn7ndbgB_1MZw4WzQbI_qa8wF6J8/view

2. Extract the zip file contents to a USB drive. 8667.upd and 8667.bin

3 Use forced update (use the USB cable with the smaller head unit connector!):

when turning on the head unit (either from the car's power supply or from the RESET button)

- touch the screen with five fingers

OR

- swipe your fingers on the screen maniacally

After that, head unit booted from USB and the installation starting.
[Android Head-Units] gduck:
Yes, you are right! The Junsun enginiers already working on it.
[Android Head-Units] M@1:
Thank-you sir i will try and tell you what is result thanks a lot
[Android Head-Units] gduck:
DO NOT INSTALL! I UPDATED MY ORIGINAL POST!
[Android Head-Units] gduck:
I hope it goes very well. Based on the name, your new firmware (from Vendor) shouldn't have caused any problem either... Can you share the download link with us, please? THANKS!
[Android Head-Units] sfde:
Many thanks for your info! :eek:
[Android Head-Units] frost_theone:
@gduck I was testing the launcher 3(didn't install the full firmware) 2 hours ago. True enough, the map will just open full screen and pressing home isn't going to help.

For my case, my unit has sleep mode off. The unit boots up in launcher 3 and will show NOT Google map on PIP automatically. The moment I pressed PIP, Google map opens full screen and cannot be closed even by pressing home.

What I did was open setting and launch Junsun Launcher, off the engine and set it to Junsun as default. Since my unit is sleep mode on, the unit sort of resets the whole memory. After that, switch to Launcher 3 again. Did many troubleshooting trial and error for almost 3 hours.

I found out that to get around this, Google map needs to open first, then press HOME (not BACK), followed by touching the PIP. Once the MAP can be seen in PIP, turn the sleep mode to ON. As of now, I had sleep mode ON. I will see how it goes tomorrow. I kinda like this launcher 3 but if the map goes missing from PIP again everytime I turn on the unit (even with sleep mode on), I will also revert to Junsun Launcher. Lol

By the way, the fan works on launcher 3 too. I tested by turning the fan off first, ran some applications and youtube so that the unit gets hot (60C), and I turned on the fan. I could hear fan spinning and the fin animation was also turning.

No other cable connected (camera, etc, CAN adapter), right? Just power.

USB drive already connected at power on, right?
[Android Head-Units] gduck:
Your 5 fingers must be on it continuously when power plugging in!

or

after power plugging in, slide your fingers on the screen left-right with "crazy" speed, continuously for several seconds!
[Android Head-Units] M@1:
Yes right sir

Hi,

i have changed the original radio from my opel insignia to a junsun v1 pro.

i have checked firmware (8667q ui02 1280x720_v39_20230712 x=1280 y=720), and tried to update from usb pen drive (32GB). downloaded zip (8667Q军灿UI02-国外-1280x720_v46_20231122.zip-Tan.zip), extracted the 2 files to root of usb pen drive, stick it to usb of android, device recogniced the update files, asked me to update, started recovery and tried to update firmware.

but after a few seconds upgrade stopped (cant find update udisk or files) and device reboot to android.

do you have a idea whats missing?

many thanks

[Android Head-Units] frost_theone:
Hi, @gduck ,

Based on your experience, is there any way to tell which USB ports are the 4 pins and 6 pins respectively? Visually both ports look the same. Reason is that I already routed those 2 cables nicely and forget to label accordingly and I might plan to update to v46 in future. As mentioned by you before, 4 pins port is the one for FW updates. Does the 6 pins port trigger the update popup as well?

Do you know if you plug 2 Pendrives at the same time, is 4 pins port indicate as USB 1 and 6 pins port as USB 2 or vice versa when viewing from Junsun file manager as attached ?

Thanks again.
[Android Head-Units] gduck:
4pin USB is important only for a firmware recovery. I can identify only if I see the head unit connector, sry.
[Android Head-Units] frost_theone:
No problem. I might update the FW in future, not now though since the headunit is working fine.

The cables/wires were already routed nicely and I find it quite difficult to remove the Android headunit to trace the cables. That's why I was asking if there is a way to verify the usb ports when 2 perndrives are used at the same TIME. (For instance which ports correspond to which USB Pendrive no.). Just want to ensure that I didn't insert the wrong usb port when upgrading FW😂😂

As far as I know, Android Auto and CarPlay can only be used for 4 pins connector. But so far, I didn't see any wired CarPlay instruction in CARLETTER. There is wired connection for AA but the moment ithe unit connects to AA, AA will just shut down (Doesn't seem to work for wired, not sure if you know though.)

Hi,

today i tried another pendrive in other usb port (attached dab receiver in that and build it behind glovebox, now update was successful.... many thanks for your hint.

but i forgot to backup existing apps...:eek:

is it possible to download default apps, preinstalled on that device?

EDIT: Seems Analog Radio receiving is a little bit better.

[Android Head-Units] gduck:
"attached dab receiver in that and build it behind glovebox"

Oh, maybe this was the reason, I think DO NOT have another USB device connected during the update.

What kind of application do you need?

i have a bad analog radio quality, and want to try to install a phantom power supply for antenna. do you have an idea if i can grab 12Vacc from Radio for this purose? connector of android radio is in near of antenna, and if its possibe i do not need to add addional cable from car lighter

many thanks

Hi,

have had a look into connector, but 8 was not conducted, so i checked for another cable, and found amp out. checked it with a multimeter and gives me power, when device is powered on.

i connected the phantom power supply, and now i have as good radio reception as in original radio :cool:

br

Chris
[Android Head-Units] gduck:
A8 pin: did you try with the radio ON (not head unit, but the radio) ?

Great!

"phantom power supply": what is its type?
[Android Head-Units] SteeveGr:
Nice to meet you guys.

gduck i think we have similar Radio, and i am happy you have a lot of experience.​

My radio is MS96NV UK 9" 6G+128G with firmware 8667Q军灿UI02-国外-1280x720_v39_20230712 X=1280 Y=720.

I bought it as Junsun V1 Plus, IPS (not QLED as this topic) but i think i am at the right place.

First opinion is good. I only tested it with power supply because i am waiting a screen protector to put on. No CanBus tested.

1: is it necessary to put the new V43 firmware you mentioned before? Mine is V39.

2: My scenario: my mobile is at hotspot mode to share internet to the radio. This way i have internet but no contacts list avaliable to call. When BT connection happens, radio opens Android auto (CarLetter app) and radio turns to hotspot automaticaly. This way i am loosing previus internet connection (Youtube, radio streaming, etc) that i had before from my mobile phone, but i have contacts list.

Any solution to have both?

3: Seller offered to give me the code for Junsun security. How does trhis app works? I don't think that the radio responds as antitheft GPS tracker when car is off and locked.

4: Igo has some issues with some eastern languages. Some characters are not visible and replaced by X.

5. Seller also offered to give me World radio code. Is this app a must have?

6. Do i need to ask any activation code for future problems?

Any other info is welcome.
[Android Head-Units] gduck:
1: if you don't have a problem, it's not important, there is no exact information on what was fixed. New Carletter version and ???

2: I have no such experience because I use 4G for the Internet. But you may be right, because when I connect to the Carletter program, my mobilephone also using WiFi. The phone programs shown in Carletter has an internet connection. I have no better idea.

3: Junsun security: "Better than nothing..." Sometimes it works, sometimes it doesn't. Now my car is just half a kilometer from where it indicates its position. :( Using Baidu map :(

How it work: you activate the program, download the mobilephone application, pair your phone using the QR code in the program.

- you have trajectory info, you can see your route

- you can set electronic fence

- you can see your car parking GPS location

But, need Internet connection to report positions. so I don't think it's worth much without a "constant" (4G) Internet connection...

4: try this: edit the sys.txt (IGO_Pal\sys.txt) file and remove or comment the [fonts] section. If not working, send a PM to me ;)

5: music, music, music :D

6. After every firmware updates, the applications (Junsun Security, network Radio) automatically reactivated, without any code.

Could you please verify wether it is a real 6GB of RAM unit? It has been reported in some Russian forums that those advertised 6GB Junsun HU are 4GB in fact.

Contact the seller, send him the screenshot showing it is in fact a 4GB of RAM unit and not 6GB as advertised, maybe he will send you some gifts to compensate, or you could even get a partial refund.

3: Yes, but there is no power when the car is locked and the engine is not running? Acc is not powering the 4G radio system. Is there any battery inside the unit? I thing no! Useful for fleet of cars, not as anti-theft system.

4: You are good :) it's ok now.
