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.

8877 na mojej jednotke Android otvorí denník atc.
Mám problém s nastavením ekvalizéra... pri každom novom spustení sa všetky nastavenia vrátia na predvolené hodnoty.
Mám ff_866x so 6gb ram a 128gb Rom.
Mohol by mi niekto pomôcť?
Ďakujem
Dobrý deň, skúste po nastavení ekvalizéra vytiahnuť všetky USB kľúče, potom vypnite kľúč zapaľovania, chvíľu počkajte a potom skontrolujte, či zostal v pamäti.

Mod translation: Hello, after setting the equalizer, try pulling out all the USB sticks, then turn off the ignition key, wait a while and then check if it remains in memory.

Szia! Vettem egy Junsun v1 fejegységet az autómhoz. De sajnos nem tudom beállítani a boot logót. A menüből kiválasztom a Ford emblémát. De indításkor nem jelenik meg. A rádió azonnal indul! Köszönöm a segítséget!!!

Mod translation: Hi! I bought a Junsun v1 head unit for my car. But unfortunately I can't set the boot logo. I select the Ford emblem from the menu. But it doesn't appear on startup. The radio starts immediately! Thanks for the help!!!

    Thanks, but I did that already 2 days ago.
    I clicked on "Menu Icon" and added the marked items but nothing has changed. Where should I find the new items?
    On my unit you find those menu icons under the application menu.

    Remove it and reboot. Try then again to change settings

    Thanks TorstenH! In the end the problems were caused by the USB drive.
    As soon as you plug in an USB drive Android is asking you, if you want to use it as storage extension or just as external drive. My theory is:
    If you select first option, the Junsun apps store their settings on the USB drive. Unfortunately this is not available early enough during but process.
    There would be a slight problem with the white noise - maybe I need to look for the gain setting or reduce the power of the amplifier - but it doesn't bother me too much.....my car is equipped with a BOSSE amplifier from the factory...I tried it in the settings to lower the audio output level but I didn't succeed (at level 9-10 the sound is very loud!). I don't know what to do, what do you advise? Should I purchase an audio filter?
    I think you should start to check if other wires/components are too close to your amplifier audio wires. Also re-placing the 4G antenna could help.

    You must use RCA outputs. RCA to ISO (speaker) adapter is needed for Bose system

    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

    In arhive is Licence DAT. Unzip and copy to a Fat 32 formatted stick.
