Why Xiaomi Redmi Note 8 Pro is constantly rebooting and how to fix it

Introduction: why the smartphone goes into a “reboot cycle”

Xiaomi Redmi Note 8 Pro is one of the most popular mid-range smartphones, but even it is not immune to hardware and software failures.If your device spontaneously turns off and on, it gets stuck on the logo. MI Or it reboots at regular intervals, a clear sign of what's called a "bootloop" -- a problem that can be attributed to a firmware failure or physical malfunctions, from a bloated battery to a damaged motherboard.

It’s important to understand that the cyclical reboot on the Redmi Note 8 Pro is 80% due to software errors, not hardware, which means that the problem can often be solved on its own without visiting a service center, but if the smartphone does not respond to buttons, warms up or makes extraneous sounds (such as squeaking), this is already an alarm signal about possible breakage of components.

In this article, we will discuss all possible causes and solutions, from basic (reboot in safe mode) to radical (flashing through Fastboot), and you will learn how to distinguish a software failure from a hardware one, and when to contact specialists.

1. Diagnostics of the problem: how to understand what is the problem

Before you start repairing, you need to determine the nature of the reboot, and that's what you decide on.

🔄 The smartphone restarts at fixed intervals (e.g., every 5-10 minutes)? → Most likely, the software or background application is to blame.
🔥 Reboot occurs when heated (during games, charging)? → Problem with battery or cooling system.
📱 The device does not turn on beyond the logo MI Or go into the rebound immediately after the screensaver? → The loader or firmware is damaged.
⚡ Reboot is accompanied by vibration, screen blinking or sound signals? → Possible malfunction of the motherboard.

Also note the conditions under which failures began:

📲 After updating MIUI? → Firmware failure.

Press the item "Switch off power" (do not let go!) before the request for a transition to safe mode appears.
Confirm the action. The smartphone will reboot with the words Safe Mode at the bottom of the screen.

If the reboots have stopped in safe mode, the problem is with one of the installed applications. Uninstall suspicious programs (especially those installed before the crashes began). If you are not sure what is to blame, reset to factory settings (more on this below).

2.2. reset to factory settings (Hard Reset)

The reset will delete all the data, but it will return the smartphone to a "clean" state, which helps if the reboot cycle is caused by:
