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 .

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.
