Disclaimer: - This is Only for educational purposes, No one is responsible for any type of damage.

1. First go to http://fota.slv.fxd.jiophone.net/ using your PC Browser.
2. Open Developer Tools and Click on the Console option.
3. At the top of the console window (just at the right of Filter box), you will find a spinner named Custom levels. Click it and turn off the Error checkbox.
4. Copy the script below and paste into the console.
5. In the console, edit the variables STB.manufacturer, STB.model, currentVersion, maxVersion and increment according to your need.
6. Press Enter in the console which will show the STB Firmware versions along with their URLs.

/*
Example Link : http://fota.slv.fxd.jiophone.net/STB/Droidlogic/JHSD200/STB-JHSD200-7.4.6.zip
1. Goto http://fota.slv.fxd.jiophone.net/
2. Replace STB options and current and max versions, and increment accordingly (Do not put to much difference between those numbers)
3. Run it in browser developer console, to scan for available firmware versions.
