Introduction

The Infinix Note 50s 5G (Model: X6870) is a feature-packed budget 5G smartphone designed for smooth multitasking, fast connectivity, and immersive media experiences. Powered by a MediaTek Dimensity chipset and running on Android 13 or 14 with XOS skin, the device is optimized for both performance and power efficiency.

However, like any Android smartphone, the Note 50s 5G may face software issues such as boot loops, system crashes, forgotten screen locks, or failed updates. When these problems occur, flashing the official Infinix stock firmware (flash file) is often the best solution to restore the device to its original factory condition.

This guide provides a full overview of the stock ROM for the Infinix Note 50s 5G (X6870), its uses, and how to flash it safely using SP Flash Tool.


What Is Stock Firmware?

Stock firmware (also called a stock ROM or flash file) is the original software provided by Infinix for your device. It includes the operating system (Android), Infinix’s custom XOS interface, drivers, bootloader, recovery, and all required partitions for the phone to function properly.

When your phone runs into software trouble, flashing the stock ROM replaces the corrupted or modified software with a clean and stable system version.


Why Flash the Infinix Note 50s 5G Firmware?

You may need to flash the stock firmware for several reasons:

  • 🔁 Stuck on boot logo or bootloop issues

  • 🧱 Soft-bricked device after failed root or custom ROM installation

  • 🔒 Forgotten password/PIN/pattern (data will be wiped)

  • 🔧 Fix bugs, app crashes, or update errors

  • 🆙 Manually update or downgrade Android version

  • 📶 Repair invalid IMEI or baseband issues

  • 🔓 Remove FRP lock (Factory Reset Protection in some cases)
