Razer is a reputed brand when it comes to gaming hardware, laptops, and related accessories. The company stepped into the Android smartphone market with its own Razer Phone. The device was launched back in November 2017 and targets the smartphone gaming community.

It’s quite likely that users have already tried to customize the device or added third-party features by flashing a custom recovery or rooting. But there was no going back from that, up until now. The manufacturer has finally released Razer Phone factory images for November, December, and January updates. Users can now download the factory image and use it to restore Razer Phone stock firmware.
