Introduction

The Infinix Note 50 5G (X6858) is a sleek mid-range smartphone offering 5G connectivity, a large display, long battery life, and decent performance thanks to its MediaTek Dimensity processor. While it’s reliable for daily use, Android devices like the Note 50 5G can occasionally face software issues—ranging from boot loops to bricking or even a forgotten password.
