Sometimes, getting the exact firmware for your phone is not quite easy. If you can’t find a rom for your phone, this tutorial will be of great help if you follow the rules.

Upgrade download and Research download are the two official tools used in flashing files or data to any spreadtrum powered device.

Before flashing firmware to a spreadtrum device e.g, Itel, MBO, M-Horse etc, you need to first of all install spd drivers on your computer which will enable it connect to your phone successfully.

Before installing the drivers, you need to disable signature verification on your system because these drivers are not signed and your system is by default not going to install it. Check this post on how to disable signature verification on your pc.

Two of the most popular spreadtrum cpu used in smartphones are the SC6820/SC8810. So many phones out there run on these chips e.g Itel, MBO, Mhorse, Samsung galaxy clones{Spd} etc.

This tool should be used with care and should be used on phones with security lock, hanging, slow response and other minor issues.  Note, this tool will not flash a new os to your phone but will wipe all user data and restore the phone to its factory settings.

To know the CPU model used in your SPD smart phones, press the Power and Volume Down button for a while to bring up the test mode. Under test mode you will find your phone’s info. If the button combo doesn’t work, try Power and Volume Up. You can also google it to know its cpu type.

Make sure your CPU model is either SC6820/SC8810 because this utility wont work on any other cpu type unless the ones listed above.
