Why Xiaomi Redmi is constantly rebooting and how to fix it yourself

If your Xiaomi Redmi suddenly starts to reboot in a loop, don’t panic. This problem is found on both new models (Redmi Note 13 Pro+, Redmi 12) and on devices from 2018-2022 (Redmi 9A, Redmi Note 8 Pro), the reasons may lie in software failures, corrupted system files, incompatible software or even hardware malfunctions.

In 80% of cases, cyclic reboot is eliminated without visiting the service center, we have collected all the working methods from basic (reboot in safe mode) to advanced (flashing through Fastboot), also, we will analyze when self-repair is dangerous and better consult specialists. If your Redmi is getting stuck on the MIUI logo or rebooting every 5-30 seconds, read on.

1. Causes of the Xiaomi Redmi cyclical reboot

Before you start repairing, it’s important to understand why the smartphone was doing fine yesterday and went into bootloop today.

🔄 Failure after update: Failed installation MIUI (especially beta versions) or interrupted updates OTA.
📱 Application Conflict: Viruses that are incompatible APK System modifications (e.g. Magisk for root rights).
🔋 Battery problems: Bloated battery or power controller failure (often on models over 3 years old).
🛠️ Hardware damage: Fall, moisture, overheating of the processor (Snapdragon or Mediatek).
🧹 Clogged Memory: Overflowing Storage (100% occupied) or corrupted files /cache.

For example, the Redmi Note 10 Pro often goes to bootloop after installing custom firmware through TWRP, and the Redmi 9C due to factory power-fee defects. If the reboots started after a fall or getting wet, the hardware is most likely to blame.

Quick Decisions: What to Do First

Start with simple steps – they help 50% of the time and don’t require special skills.

Forced reset

If the screen is getting stuck on the MIUI logo or the smartphone is rebooting every few seconds, try the hard reset:

Press the Power + Volume button for 10-15 seconds.
Release the buttons when the device vibrates or the screen goes out.
Wait 1-2 minutes, sometimes the system will repair itself.

Safe loading mode

Safe Mode disables all third-party applications, and if it stops rebooting, it's the software's fault:

On the phone turned off, press the power.
When the Redmi logo appears, release Power and hold the Volume Down.
Hold on until you see the Safe Mode label at the bottom of the screen.

In Safe Mode, remove newly installed apps or clear the cache through Settings → Apps.

Make sure the battery is charged. >30%|Make a backup copy of important data|Remember your Mi Account (if tied)|Prepare. USB-cable-->

3. Resetting settings to factory

If Safe Mode doesn't work, the next step is hard reset, which will delete all the data, but it will return the system to working condition. There are two ways to reset on Xiaomi Redmi:

Suitable if the phone turns on, but cyclically reboots:

Turn off the device.
Press Power + Volume Up until the Recovery menu appears.
Select Wipe Data → Wipe All Data (Confirmation – Power).

Install the Mi Flash Tool and Xiaomi drivers.
Press Power + Volume Down to enter Fastboot (a rabbit with android will appear).
Connect your phone to your PC and type in the command line: fastboot erase userdata fastboot erase cache fastboot reboot

What if your phone needs an old Mi Account after a reset?

If you forget the Mi Account data associated with your phone, the reset won’t help — you’ll need an official unlock through the service center. Attempts to bypass the protection software (for example, through EDL) can lock the device permanently.

Attention! On Redmi models with a Mediatek chip (such as the Redmi 10A), a reset via Fastboot may result in a loss of IMEI. Before the procedure, save a backup of the NVRAM partition.

4.Battery and power problems

If the smartphone reboots when charging, or when battery levels drop below 20%, the problem is most likely in the battery or power controller.

🔌 Test with another cable/block: Use the original Xiaomi charging (5V/2A Cheap cables can cause voltage surges.
📊 Checking the status of the battery: Enter in the dialer ##4636## → Battery information: If Unknown status or health level <80% — Replace the battery.

The phone is warming and turning off	Short circuit in the battery	Immediate replacement!

Critical information: If the battery is swelling, do not attempt to puncture or heat it - this can lead to fire.

5. Phone flashing

If the reset didn’t work and the hardware problems are ruled out, you just have to reflash the device. Xiaomi Redmi has two official methods:

Update via Recovery (without loss of data)

Suitable if the phone is turned on, but it is unstable:

Download the latest version of MIUI for your model from the official website (select Recovery ROM).
Rename the file to update.zip and place it in the root of the phone’s memory.
Press Power + Volume Up to Enter Recovery.
Select Install update.zip and confirm the installation.

Connect your phone to your PC, in Mi Flash, select a folder with firmware and press Flash.

Attention! Fastboot firmware deletes all data, including files in internal memory. On models with a locked bootloader (Redmi Note 11 and later) you will need to unlock through the Mi Unlock Tool (can take up to 720 hours of latency!).

💡

Before you run the firmware, check the bootloader version (fastboot getvar anti). If the value is anti: 4 or higher, you will need an authorized Xiaomi developer account to unlock.

6. Hardware malfunctions: when to contact the service

If all the software methods have been tried and Redmi is still restarting, the problem is the hardware.

🔥 Overheating: Phone heats up >50°C even in plain (check in ##4636## → Battery temperature).
💥 Physical damage: Cracks on the board, oxidation of contacts (visible when disassembling).
📡 Communication module failure: Reboots when calling or turning on mobile data (modem problem).
🔌 Power button malfunction: The phone is switched on/off spontaneously.

Breakdown	Cost (₽)	Duration of repairs
Battery replacement	1 200–2 500	1-2 hours
Food-in-charge repairs	2 000–5 000	1-3 days
Replacement of the power button	800–1 500	1 hour
Diagnosis + soldering of chips	3 000–10 000	3-7 days

Important: If your Redmi is warranty, do not disassemble it yourself - this will void warranty obligations. Contact the official Xiaomi service with a check and a box.

7.Prevention: How to Avoid Resets in the Future

To avoid recurring problems, follow these rules:

🔄 Update. MIUI Regularly, but do not install beta versions on your main device.
🛡️ Use Original Accessories: Charging and Cables from Xiaomi Reduce Risk of Power Spikes.
🔋 Do not drain the battery to 0%: Optimal range - 20-80%.

For models with AMOLED-screens (Redmi) K50, Redmi Note 12 Pro+) You should also turn off Always On Display (Settings) → Screen. → Always On, as this feature speeds up battery wear.
