Custom ROMs are developed by third-party developers for a specific device. Most of the Custom ROMs are feature-packed and fast which makes them a better alternative to the stock firmware.

As the device is being powered by a Spreadtrum CPU, wee will be using SPD flash tool or Upgrade tool to manually flash the Firmware. This is an easy and straight forward process. We recommend you to follow each and every step carefully without skipping any.
