You’ll get step-by-step instructions, from simple (cleaning the cache) to radical (fastboot rebooting), and how to tell the difference between a software glitch and a hardware breakdown and when to carry your phone to a service center.

1. Reasons for the constant reboots of the Redmi Note 6 Pro

Before you start repairing, it’s important to understand what exactly caused the problem.The Redmi Note 6 Pro has a few “weak spots” that most often lead to cyclic reboots:

• 🔋 Battery: wear after 2-3 years of use, bloating, short circuit. Typical symptom - the phone reboots when charging or at a charge level below 20%.
• 📱 Software glitches: damaged system files after update (MIUI 10/11/12), Application conflict, viruses.
• 🔌 Contacts and plumes: oxidation of the charging connector, poor battery contact with the motherboard.
• 🔥 Overheating: Protection is triggered due to dust-clogged ventilation (relevant for intense gaming or charging).
• 🛠️ Failed firmware: interrupted update via OTA or errors in manual installation of Custom ROM.

According to service center statistics, 60 percent of the time is software, 30 percent is battery, and only 10 percent is other hardware problems, but you can't tell without a diagnosis. We'll go over how to identify the cause ourselves.
