Introduction:

In this tutorial we will learn how to get access to your kingview project if you have missed or forget your project password.

Disclaimer: This tutorial is for educational purpose only, please do not use if the project is locked by the third person.

Instructions:

• Step 1: Take backup of your project and make changes to copied files and not to the original program.

• Step 2: Download any hex file editor. (In this tutorial we are using WinHex editor).

• Step 3: Open tagname.db file from program folder with hex editor.

• Step 4: As shown in picture bellow, change these hex values to zero.

• Step 5: Save the tagname.db file in hex editor and close it.

• Step 6: Now you can open the project in kingview software without password.

Note: With this trick, you can get access to project tags and communication data. But you will still need password to get access to the pages. Also you will not be able to change the password without knowing the original password.

If you want to fully unlock the project, you can take paid help from any expert freelancers or you can simply reach out to us with the project files. email

XS3868 is based on OVC3860 RF transceiver. OCV3860 is low voltage single chip Bluetooth RF transceiver providing Bluetooth stereo solution. OVC3860 is a 2.4GHz transceiver with Bluetooth V2 baseband and can transfer 20bit high quality audio codec. OVC3860 is fetured with inbuilt power management and support advance lithium ion batteries with switch regulator.




In this project we are going to learn how to program XS3868 audio Bluetooth module using TTL USB module. Here you will learn how to change the costume Bluetooth device name and the security password of XS3868 device.

Requirments :

1. XS3868 module
2. USB TTL serial module
3. 3.7v li-ion battery or any 3.6v-4.2v voltage source
4. LED with 470 Ohm resistor (optional)
5. Compute (to communicate with the device)

Circuit Diagram :

Steps:

1. 1. Connect xs3868 with battery then wire its reset terminal with 1.8v output terminal of xs3868.
   2. As shown in diagram connect TX of xs3868 to RX of UART module and RX of xs3868 to TX of UART  module.
   3. At last connect UART module GND terminal to common ground of xs3868.

1. Download  “OVC3860 RevD Develop” tool from link given bellow at download section.
2. Connect UART module to your computer USB port and check the COM port number for UART device, if it is other than COM-1 then change it to COM-1 first. [Here’s How To]
3. Open OVC3860 RevD Develop tool with administrative rights, you will see the window similar as below,
4. Now reset xs3868 module from reset pin and you will see the your device connected in tool window with green circle on the top.
5. Now scroll down to item Local Name and Pincode, this is your Bluetooth name and password.
6. Change it to desired Bluetooth name and password as you want.
7. Click Write ALL button in tool and if everything went right, you will get Success message pop up on screen.
