What are the changes in the new v94 compared to the old v90?

Thank you.
[Android Head-Units] TorstenH:
Only the Chinese can answer this question. As usual they don't provide a changelog.
[Android Head-Units] TorstenH:
Please note that the Junsun firmware version numbers (v90, v94, ...) are not related to the OS version (build number).

Sometimes the Chinese just change or add some apps or configurations to support additional CAN boxes or other functionalities by keeping the OS as it is. Nevertheless they count up the version number.

If your system is running well an update is in most cases just waste of time and finally a chance to kill your head unit.

And in meantime we all know that the displayed Android version if fake and the security patches are outdated. NEVER use your primary accounts (e.g. Google) on those head units. Especially don't forget that the head units are pre-rooted and every app can execute root commands without the need to request an acceptance from the user.

I everyone!

I bought the Junsun V1pro 4Gb+64Gb from here.

Everything was working correctly including carplay.

By mistake I execute the code 9191. I've managed to use a License file.

After that I've updated the firmware to 8259P_军灿UI02v1280x720-国外_v94_20230729.zip downloaded from the first page of this thread.

Everything is working correctly except carlink that is requesting for activation code :(

Can anyone help me?

kind regards 🙏

So the new firmware don't change the system still Android 9 Pie. What's new only Autolink gets update to 2.0.25. The core system is untouched. I took a look into build.prop and some folders.
[Android Head-Units] PrinceLc:
Try CarLetter maybe CarLetter is pre activated this is in my case

TorstenH

While there are no change log provided with each firmware release, what could be interesting would be to have the version of some software, especially for AA & Carplay : we would not know the changes but at least know if a release has changed and therefore search for feedback and maybe try that version. What do you think if you add the releases after each version on first post ?

V51

Autolink : sd 2.0.19

V81

Autolink : sd 2.0.25

V90

Autolink : sd 2.0.25

Carletter : 7.4.3.20230607

V94

Autolink : sd 2.0.25

Carletter : 7.5.6.20230726

V107

Autolink : sd ???

Carletter : 7.5.8.20230809

V113 : 8259P_军灿UI02v1280x720-国外_v113_20231122.zip-Tan

Hello everyone. I've got a little problem that's starting to freak me out. I bought a junsun v1 pro (mt8163) unit a few months ago for my ford fiesta and I had problems with the canbus, since it did not recognize the vehicle buttons. The sellers have sent me another one. When I went to test it, the radio directly went into a loop at boot that does not allow me to access the main menu. After system startup loading bar, it shuts down and reboots, and doesn't get out of that loop. I have written to the vendors and they have sent me a firmware and instructions that do not work in my case, since I cannot access beyond the loading bar. I don't know how to enter recovery mode, I don't know what else to do. I imagine it must be a firmware problem, but I don't understand why it stopped working from one day to the next. Could someone guide me? thank you very much in advance.

I leave an image of the seller's comment with the supposed solution, a link to the video to see the problem and a link to download the original firmware for the mt8163

video demo loop

hello, just bought Junsun V1 Plus 4gb + 64gb soc 8259, have carplay issues with v81 just updated to v90 yesterday and same, seller gives me the link for v94, let's try it out today, i'll leave a feedback.

My issue is carplay works at 1st connection wirelessly but if i disconnect in some cases i cannot reconnect again even in usb mode, i have to reboot from factory menu by saving paramaters and that erase all modifications saved as EQ settings, home screen app etc...

Didn't find a way to reboot normaly like all android system, i don't find how to access power menu option, do you have any solution guys ?

Will check by the way versions of carletter in v90 and v94, idk if autolink is installed, i don't have the app selectable on the menu, so maybe running in background or replaced by carletter.

I can also give a feedback on Carlinkit box as i used on my previous poor 1gb 16gb screen that came with the car when i bought it, used with Autokit app, u have a lot of settings and 60fps when running carplay that u can't reach with "software emulate" carplay that carletter does but had some connection/disconnection issues aswell.

Think all methodes have some issues, just looking for a stable one even if it is 30fps or a bit less.

Sorry if i make any syntax mistakes, learning english everyday to improve it.

I'm using Agama which can be found in PlayStore. It's working without any problems with better functionality. But there are other launchers, too. Just search the other threats, Google and PlayStore so see what's available.

Here you can find the apps to make the stock apps available in other launchers:

[Android Head-Units] TorstenH:
It replaces the stock launcher so it will be shown as soon as you click the home button and it will be set as standard launcher in Android settings. Surely from a file system perspective the files of the stock launcher won't be overwritten so you can return to current state.

Thank you
[Android Head-Units] aaanonymous:
Good question as I was wondering the same.

My Eonon EA2189S headunit originally had an Eonon Android 10 OS installed. I installed the Junsun V1 Android 10 firmware. The Android 10 version of the Junsun V1 firmware installs fine from a USB stick containing the 8259P.bin and 8259.upd files.

8259P_军灿UI02v1280x720-国外_v31_20220225.zip (currently installed)

The Junsun V1 Android 11 firmware fails to install. When reading the USB stick containing the 8259P.bin and 8259.upd files, an error is displayed on the screen: "Fail, please check USB and files...".

8259P_军灿UI02v1280x720-国外11_v1_20220323.zip (fails to install)

8259P_军灿UI02v1280x720-国外11_v3_20220422.zip (fails to install)

My questions to this forum are:

1. What are the differences between the Android 10 and Android 11 Junsun V1 firmwares?

2. Does the Android 11 firmware require hardware with addtional features, for example: built-in Wired/Wireless Carplay/Android Auto, etc...?

3. Has anyone installed the Junsun V1 Android 11 firmware on a 825xP device that originally had Android 10 installed, Junsun or any other brand?

4. If you did, could you please share how it was done?
[Android Head-Units] bronco501:
So, I think it's normal that you can't upgrade a device with Android10 with a firmware for a android11, at least with this kind of firmware, maybe you can't do it for hardware limitations.

Finaly I update my device with 8259P_军灿UI02v1280x720-国外_v31_20220225.zip firmware, from a v27 firmware publicated on december. I think this update doesn't change anything, I had to reconfigure all the system from the begining, install app's once more, etc. Maybe it will be helpful to include a change log in future firmwares, it's a hard work to update and maybe it's not necessary and have no changes

I follow using car launcher app because can't change main screen configuration of the Junsun launcher, I hoped that it could be changed, and to be able to remove the horrible car from the main screen but no way
[Android Head-Units] TorstenH:
Because this thread is about the MTK825X variant of the Junsun V1 pro it's better to discuss your topic here.
[Android Head-Units] Meeyo:
Seller tells me that v94 update fix Carletter issues, i hope it will.
[Android Head-Units] TorstenH:
To avoid confusion, it's getting more and more important to differentiate between "CarLetter" and "AutoLink".

Both apps are "pre-installed" (don't want to go into technical details here) and can be enabled via the factory settings (code 8878, section Others). In factory settings AutoLink is labeled as "Suding".

Reboot of the head unit is possible with code 4. But because I can't keep numbers, I've written the small app "Reboot.apk" to get an app icon to easy reboot the head unit: https://xdaforums.com/t/junsun-v1-start-equalizer-aux-bt-music-carinfo-from-launcher.4237797/
[Android Head-Units] Meeyo:
Okay i see clearly now, tried AutoLink and it isn't activated for me, back to Carletter and Thanks for the Reboot tips and APK.
[Android Head-Units] Meeyo:
Feedback after update v94, it's better, USB carplay works fine but it takes around 15sec to connect, wireless carplay still have some minor issue, i sometimes have to trigger bluetooth option to make it work but it's better.

About Carletter/Autolink version :

- v90 : Autolink > sd_2.0.25, Carletter > 7.4.3.20230607

- v94 : Autolink > Same, Carletter >7.5.6.20230726

i have a question, i took the plus version for the IPS Screen 720p but the views angle are very poor, i lose a lot of brightness when looking at it at driver spot (so 99% of the time), i put everything possible in white background to see better but when sun is shining + screen reflecting it's still hard to see so do you have any tips like maybe anti reflecting screen protector or idk if it's possible to increase brightness over software maximum ? thx
[Android Head-Units] pctjune:

Your feedback is with Carletter ? When you say it's better, you mean Carletter from v94 vs v90 ?

How would you compare it to Autolink ?

That's an excellent idea 💡

I'm sorry. My problem is firmware. I have not realized that it is for another version of my same model. It has nothing to do with the thread that you sent me, but thanks.
[Android Head-Units] pctjune:
so it means both are not activated by default ? is this linked to hardware ? Or startin v90, both are pre installed but Carletter is the only one we could activate ?

unless error, you have Junsun V1 Plus 4gb + 64gb soc 8259 : so on this hardware, this is Carletter only ?
[Android Head-Units] Meeyo:
Yep, CarLetter only activated, i think just the one installed at 1st boot is activated by default.
[Android Head-Units] pctjune:
so if we wants to switch from the first activated one, it's possible but you need to re install firmware ?
[Android Head-Units] TorstenH:
Codes for AutoLink can be bought by Junsun on Aliexpress. The license gets stored on a separate partition and survives firmware updates.

The license is valid for Android Auto (wired and wireless) or CarPlay, whereby CarPlay wireless is a separate licence.
[Android Head-Units] PrinceLc:
CarLetter works v90 in my case with Android Auto perfect from day one it connects prompt wirelessly. Only with cable no connection. Maybe it's fixed with v94 ok. Tomorrow I will flash v94, I checked with 7zip the bin file to see changes and sow that CarLetter was bigger in file size and the whole firmware is bigger. And yes Junsun V1 Plus 4/64 CarLetter is preactivated by default.

You just need to copy the zip file or unzip the file and put in a USB key?

Try a 3rd USB drive and don't use as Android device to download the update and to copy it to the USB drive.

But @DenisBeljata is right. In most cases the reason is wrong CAN setting or the SWC (if it's based on resistance matrix) is not connected correctly.

Does anyone know how to do a full backup of all the partitions? I guess I have to dump the mtd blocks, but don't want to screw it up as I want to play with the new firmware versions.

My model is customized for Audi 2009-2012 models and has a screen of 1280x480 (I think), but same CPU and 4/64 GB. The original firmware allows switching to the original car screen, which it replaces. Other than that, there's nothing special about the car communication, just CANBUS 152 for doors, steering wheel controls, lights, etc.

A more advanced question - is there a way to view which canbus messages get received? Or which activities are mapped to which canbus message?
[Android Head-Units] DenisBeljata:
CAN -bus ecu's started in 2005 and newer vehicles.
