Fastboot Mode on Xiaomi Redmi: A Complete Guide for Beginners and Experienced Users

Have you ever experienced a situation where your Xiaomi Redmi stopped loading and a black screen with the words FASTBOOT and a white robot appeared on the screen?

What is Fastboot and why is it needed on Xiaomi Redmi?
