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
3699 - update_apk2
5699 - update_apk3
7788 - atc_log (engineering menu of the 4G modem)
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.
2134 - appinfo_id_num
6666 - install_id_num
7777 - install2_id_num
1616 - display_id_num brightness
2064 - testmode_id_num
1414 - reboot_id_num
9191 - destroy_id_root_num
9090 - destroy_id_num
1313 - radio_reset_num

I've removed the link to 4pda. 4pda.ru is not only another phone related site (and absolutely not affiliated with XDA) but also well known for the distribution of malware and warez. References to 4pda are not accepted on XDA.

Hello, I also have a Junsun V1 Pro. Could someone do me a favor? I accidentally changed something in the radio settings in the secret menu (8788). Could someone take screenshots for me of what the normal values are? At AliExpress the support doesn't seem to understand me ... My English is not the best.

Thanks very much!

Regards from Germany

This is from another head unit but it's the same click path on Junsun:

Don't mess around with the codes if you don't know what you're doing. A lot people killed their devices by playing around.
Oh thank you LOL. I though that was only for changing the logo with the 5678 code because is the same menu that appears when tapping the "change booting logo" but now i realize is for all the codes.
Great, i need it because my unit doesnt have the option or app to set the color/light to the buttons.

    Your question does not fit to this thread. Please try to find a thread handling the SWC (steering wheel control) topic or create a new thread.
    Thank you.
