Custom SWC key study with CAN box in place...

You all know that the SWC keys are assigned to a fixed function on the head unit.
But the Chinese developers prepared a SWC CAN key study with code 0127.
Unfortunately the corresponding activity is not defined in the manifest file of the central MainUI applications.

I'm searching for fearless victims try to replace the MainUI application by a modded one. Sure you should have SWC via CAN box in place and you should know how to flash a firmware in case of issues.

MainUI from
8259P_军灿UI02v1280x720-国外_v81_20230427.zip
with enabled settings code 0127

Edit:
Added MainUiUpdater. The new MainUI.apk needs to be placed in Download folder.
Only suitable for MTK825X
Hi TorstenH,
Thank you very much for your work on this unit :)
Just a question : possible to control the original screen on a peugeot 308 (2010) with this MainUI modded ? :)

Hi TorstenH
this is what happened here.



II will update to v81. That's why I tested.

Thank you for providing the video. That's the original behavior of MainUI - crashing after you entered the code with a direct restart of MainUI.

New version of the updater app should show the log message "Finished! Please reboot your device", now.

Shure, you can directly try to enter the code before and after a restart so see if reboot is really required.

I did just that. I tested the code before and after a reboot . The result was the same. Here you have a new video with version 0.2:


I disable the sleep mode if i have problems with the reboot ;)

We're on version 0.3, now.

Good you know how to force reboot. Unfortunately the change of MainUI was not persistent so I changed the way to make the partition writeable.
Adding a reboot button to the app would be piece of cake.

Thank you for your very helpful tests.

I didn't use the Reboot app because the HU freezes after running the updater
A new icon has appeared. you can see in the video.
Version 0.3

The new icon opens the Bluetooth application (?). Code 0127 does the same as in other versions. Sorry for the lack of time. I will make a short video.

Edit
I cut the video

Thank you for your effort.

Bluetooth is the standard activity of MainUI. The added icon may be just a weird side effect.
Because I'm confused why the code isn't working I want to ensure the replacement itself works. I added a new version of MainUI. This one should add a launcher icon "caninfo" with the radio icon.

With the new mainui, code 0127 opens the steering wheel controls screen. I couldn't record anything, but I just tried 2 times. In Agama, a new carinfo icon does not appear. I didn't see it in the other lanchers

Even if the icon doesn't appear it's great 0127 is working. Unfortunately I don't have a CAN box in place so I can not test by myself.
If the screen is similar to the well known SWC learning screen you need to clear the current assignments first. Nevertheless the idea this could work with CAN is based only on the name of the screen (CanCarInfoSub3Activity).

Another change could be to disable the standard functionality of the SWC mode button. This would allow to keep the menu icons setting, have a working radio app and use AppSwitcher to switch between apps. Are you interested in testing?

    Ok, just one last question...what do you mean by "No glue"
    I don't know if it will fix your problems. 😉

    Yes, you can use a hammer 🛠. But you should use it before the update 😂

    Code description from {Mod edit}

    Please note: Don't just try a code without to know what happens. E.g. 9191 will lead to the message "device not activated" and you need a file called license.dat.

    8888 - restricted settings menu
    8878 - full settings menu. Mostly what you're looking for.
    Additional info can be found here: https://forum.xda-developers.com/t/junsun-v1-factory-settings.4282295/
    1111 - load monitoring
    0 - update (mcuupdate_num)
    1 - some menu (csudy_num)
    2 - barcode
    3 - another barcode 8938003992756585897
    4 - reboot
    5 - color setting
    6 - set a new random Bluetooth name
    7 -
    8 - gis whitelist reset
    9 - system notification: device activated (in Chinese)
    0129 - CAN DATA
    5555 - save settings
    1912 - factory setup
    1812 - shop setup
    12345678 - update_apk update MainUI

    8877 - atc_factory
    Menu for changing the cutoff (filter) frequencies for the sub and line outputs (relevant for those who use external amplification):
    Code 8877 ---> Audio ---> Scroll to Sound Effect ---> Bass (or Alto (Middle), Treble).
    And also there is a setting and the ability to completely disable Loudness.
    USB mode can be changed here if required, too.
    7758258 - obligatory mode !! do not enter !!! Complete crap going on
    5678 - changing the menu code logo
    3234 - apk_install_pwd
    Alternatively (untested!) restore the engineering menu settings to the factory settings.

    Hello, although it was warned here at the beginning not to access code 9191, someone entered the code and even asked the question "If you access Code 9191, what is the solution to the problem" Now "Device No Activated" appears on the tablet display. Personally, I hadn't had time to read this warning and I didn't remember the access code 8878, so I put what came into my head. And yes, this very 9191 and 1515 (it was not listed in the table) I think because, as you can see in the photo, every time I turn on the device, those two options appear in Chinese. I used the translation and it says on the left "System Hint - No file was found - Try again", and on the right the option "Return". If I access the left option "System Hint" nothing happens. If the option on the Right is accessed, the device enters normal operation mode, but be careful, "Device No Activated" is permanently displayed and from time to time the two Options appear again in Chinese. As Torsten also said, I think the device needs a certain file. He says this is called "file called license.dat" Now I ask once again: Has anyone else gone through the same problem? If so, can you explain or post the solution or better that missing file "File called license.dat"?

    If someone used Code 9191 and got the red message on the screen "Device Is No Activation", maybe the post is useful.



    - This is the code for my variant Jusun 8259 , V1Pro 4GB\64GB\WiFi .

    - dmZERXpiS3BJMHBPUWs4PSMyMDIwMTEzMDEwMjQxNyM=##*10000

    The Chinese technician asked me for a picture of the back of my device. Probably to make sure of the version I have. I posted the picture for those interested. I warn that the code should be written in Notepad format and the stick should be FAT32 formatted. I have also posted the film sent from China as well as the video I took unfortunately after the procedure. For me, things went more simply than what is seen in the Chinese one, that is, I proceeded exactly like this: After Fat32 formatting the stick and copying the code, with the device turned off, I inserted the memory stick into the USB 1 port, then I turned on the device, it opened (in my case) the loucher AGAMA and the window with options in Chinese appeared. I left it waiting without giving any command, and after 10-20 seconds another window appeared automatically with another inscription in Chinese, then the device turned off by itself and reopened and I found that I got rid of Device is No Activation. I want to point out that I have 4G with a SIM card, so the internet is permanent. In order for the procedure to succeed, you must have the device connected to the Internet, have a Hot Spot or Wifi. Otherwise, the procedure will not be successfully completed. I wish you patience and success.
