Introduction
The Infinix Note 50 Pro 5G (Model: X6856) is a powerful mid-range smartphone designed for users who demand high performance and modern features. It comes with a sleek design, a high-refresh-rate AMOLED display, 5G support, and a capable MediaTek Dimensity processor. Running on Android 14 with Infinix’s latest XOS, it offers a smooth and rich user experience.
However, like any Android smartphone, it’s possible to encounter software issues such as boot loops, stuck on logo, failed updates, or system corruption. In such cases, flashing the official Infinix Note 50 Pro 5G stock firmware (flash file) can help restore the phone to its original factory state and fix most software-related problems.
This guide explains the firmware details, the reasons to flash, and step-by-step instructions for flashing the firmware on the X6856.

Flashing the stock firmware will overwrite the existing system and restore the device to factory condition, removing bugs, glitches, or modifications in the process.
