Xiaomi phone reboots without stopping and does not turn on: what to do in 2026

Your Xiaomi has suddenly become a brick: the screen flashes with the MI logo, the device goes into an endless reboot, and all attempts to turn it on end in the same cycle? This problem is familiar to many owners of smartphones of the brand, from the budget Redmi to the flagship Xiaomi 13. The reasons can be hidden in software failures (damaged firmware, conflict updates) and hardware malfunctions (discharged battery, damaged motherboard).

The main rule is: don’t panic and don’t rush to bring your phone to the service center. In 80% of cases, you can solve the problem yourself, even if the device does not respond to the buttons. In this article, we will analyze all possible causes of cyclic reboot, as well as give step-by-step instructions from elementary (check charging) to advanced (firmwareware via Fastboot).

1. Checking the underlying causes: charging, buttons and external factors

Before you start complex manipulations, eliminate trivial problems. Often, the endless reboot is not related to a breakdown, but to the banal errors of the user.

• 🔋 If the phone is dead, it may be stuck trying to turn on. Connect the original cable and power supply (at least). 18W), Wait 30 to 60 minutes. The charge indicator may not burn -- that's normal.
• 🔌 Faulty cable/charging. Try another cable (preferably from Xiaomi) and an outlet. worn-out wires or weak current (5W) Can cause failures during launch.
• 📱 The power button hangs. Press and hold the power button for 10 to 15 seconds, sometimes it resets the cycle. If the power button is drowned or stuck, you need to disassemble it.
• 🌡️ Overheating or cold: If the phone overheats (for example, after a game) or overcools (lies in the cold), let it warm up/cool down to room temperature.

If you do this, you can reboot your phone anyway, move on to the next step, and the important thing is, don't try to turn on your device hundreds of times in a row, which can make the problem worse, especially if it's a damaged firmware.

2. Forced reboot and entry into Recovery mode

If the phone doesn't respond to normal on, try hard reset via a button combination, which works even on completely dead devices if the problem is software.

Instructions for most Xiaomi models (including Redmi, POCO, Mi):

1. Turn off your phone (if it’s in a reboot cycle, wait until the screen goes out).
2. Press the power button + volume button at the same time.
3. Hold on for 10-15 seconds until the Mi logo and Recovery menu appear.

If the combination does not work, try alternatives:

• 📱 For older models (Redmi) 4/5, Mi A1/A2): Nutrition + Turning down the volume.
• 📱 For POCO F1/F2: Nutrition + Volume up. + Home (if you have a physical button).

From the Recovery menu, select Wipe Data or Reboot. If the phone turns on after that, the problem is solved. If not, go to the firmware.

💡

On some Xiaomi models, the Recovery menu is in Chinese. To avoid mistakes, focus on icons: the arrow icon for reboot, the basket for data reset.

3.Reset to factory settings via Fastboot

If Recovery is not available or helps, try resetting your phone via Fastboot mode, a method that requires a connection to your computer, but is effective even in severe firmware failures.

What you need:

• 💻 Windows computer (or Mac/Linux driverless ADB).
• 🔌 Original. USB-cable (not wireless charging!).
• 📦 Archive from Google Platform Tools (download and unpack).

Step-by-step:

1. Turn off your phone (if it is in a cycle, wait for it to turn off).
2. Press Power + Volume down before the screensaver Fastboot (robot with open stomach).
3. Connect the phone to the computer.
4. Open the command prompt (cmd) in the folder with Platform Tools and type:

fastboot devices

If the device is determined (the serial number appears), reset:

fastboot erase userdata


fastboot erase cache




fastboot reboot

If the cycle repeats after rebooting, proceed to flashing.

4. Flashing the phone: official and informal ways

If the reset didn't work, it probably damaged the firmware, which you'll need to reinstall. Xiaomi has two ways of running the firmware:

1. Official – via Mi Flash Tool (requires unlocked bootloader).
2. Unofficial – via custom recavery (TWRP), if the bootloader is blocked.

Important: the firmware deletes all data from the phone. If the device had important files, try to extract them first through ADB (if the phone turns on even briefly).

Method 1: Firmware via Mi Flash Tool (for unlocked bootloader)

• 📥 Download the firmware for your model from the official website (choose the version of Fastboot).
• 💻 Install the Mi Flash Tool.
• 🔧 Connect your phone in Fastboot mode, select the firmware in the program and press Flash.

Method 2: Firmware via TWRP (if the bootloader is blocked)

This method is more complex and requires pre-installing a custom recapvery. Detailed instructions for your model can be found on the XDA Developers forum.

💡

If the phone doesn't sew and it gives you an anti-rollback error, you're trying to install an older version of the firmware than the one before the crash, in which case you're looking for firmware with the same or newer Anti-Rollback number.

5. Hardware malfunctions: when the "iron" is to blame

If none of the software methods worked, the problem is probably hardware.

• 🔋 Faulty battery: If the battery is swelling or discharged instantly, the phone may reboot in cycles. Check the battery visually (blown is noticeable) or connect to a known power source.
• 🔌 Damaged charging connector: Oxidized or bent contacts can cause short circuits and power failures.
• 📱 Motherboard problems: Overheating, moisture or falling can damage the chips, and only repairs at the service center can help.
• 🛠️ Faulty power button: If the button is stuck or the contacts are gone, the phone can constantly reboot.

A critical sign of hardware malfunction: the phone is not detected by the computer in Fastboot mode, does not warm up when charging and does not respond to prolonged retention of buttons.

6. Features for specific Xiaomi models

Some Xiaomi models have unique "diseases" that lead to a cyclical reboot.

• 📱 Redmi Note 8/9/10: Often suffer from power controller failures, the solution being to replace the motherboard or the firmware with the Fast Charge turned off.
• 📱 POCO F1/F2: Problems with EMMC-If the phone reboots after 10–15 Minutes of operation, memory chip replacement is required.
• 📱 Xiaomi Mi A2/A3 (Android One: The reboot cycle may be linked to locking the bootloader after the update.The solution is unlocking through the Mi Unlock Tool.
• 📱 Redmi 4X/5A: Older models often die because of battery wear. Battery replacement solves the problem in the battery. 90% case.

If your model is not on the list, look for information on thematic forums (for example, 4PDA or XDA), often users share unique solutions for specific devices.

💡

For Xiaomi models with MediaTek processor (e.g. Redmi 9/10), use SP Flash Tool instead of Mi Flash Tool. It works better with chipsets from this manufacturer.

7. When to contact the service center?

If you’ve tried all the methods, but the phone is still going into reboot, it’s time to turn to the professionals.

⚠️ Note: If the phone does not turn on even after firmware, does not warm up when charging and is not detected by the computer - this is a sign of hardware failure (short circuit, damage to the board, dead processor). Further attempts to “resuscitate” it on their own can finally disable the device.

• 🔧 The phone does not respond to Fastboot and is not detected in Device Manager.
• 🔥 Only part of the body is heated (for example, near the camera or charging connector).
• 💥 There were physical injuries: fall, water hit, impact.
• 📉 The battery is swelling or an electrolyte flows out of it.

The cost of repair in the official service Xiaomi depends on the problem:

• Battery replacement: 1,500–3,000 ₽.
• Maternity Board Repairs: 3,000–10,000 ₽.
• Replacement of the charging connector: 1000–2 500 ₽.

Before visiting the service, it is necessary to:

1. Uninstall all accounts (Google, Mi Account) from your device (if it is turned on for a while).
2. Keep a check or proof of purchase (for warranty repairs).
3. Check if the service works with your model (some workshops don't take the old Redmis).
