Previously, I posted an article on how to fix your Infocus Android phone if it crashes or bricks resulting from your use of the in built firmware update system (OTA). In this article, you’ll learn how to flash your device with it’s stock firmware manually.

This guide covers two different firmware flashing methods. The first method will teach you how to flash your device firmware without having having to boot into recovery mode, while the second guides you to flash the firmware manually via recovery. One good thing about Infocus devices is that, you don’t need a PC to flash your device firmware package.

Now before you go ahead, it is very important to charge your device to at least 50% before trying to flash any stock firmware or custom rom.
