When a favorite smartphone suddenly stops responding to commands or flashes its logo endlessly, it always takes you by surprise.If your Xiaomi reboots and doesn't turn on, it can indicate both a software failure and a serious hardware malfunction. Device owners often encounter a so-called bootloop when the phone gets stuck in the operating system's startup cycle.
You don't have to panic at this point, because in most cases, you can solve the problem yourself without going to the service center. Android system errors are often correctable by resetting settings or flashing. However, it is important to act consistently so as not to aggravate the condition of the device and not lose important data.
Next, we will look at the main causes of this problem and step-by-step methods for eliminating it, you will learn how to diagnose a malfunction of the iron and software part, as well as what tools will be needed to resuscitate the gadget.
The main reasons for the endless reboot Xiaomi
Before you start taking action, you need to understand the nature of the failure: if the phone is turned off and turned on, the software is most often to blame, it can be a failed system update, a conflict of recently installed applications or an overflow of internal memory.
In some cases, the problem is deeper. Hardware malfunctions, such as battery wear, power button plume damage, or power controller failure, also cause the device to behave in a chaotic manner.
⚠️ Warning: If the device was flooded with water or fell from a height, software recovery methods may be useless.
The impact of malware should also be considered: downloading applications from unverified sources often causes the operating system to fail to boot properly, and the virus blocks the bootloader from operating normally, sending the gadget into an endless cycle of reboots.
Diagnostics should start with prior events, and if you've recently installed root rights, changed system files, or installed custom firmware, the probability of a software conflict is as high as one hundred percent, and then you can go back to factory settings.
Forced reboot and check of buttons
The first and easiest step is to try to perform a forced reboot, which helps to reset static electricity and stop the stalled processes that keep the system from starting, and most Xiaomi and Redmi models need to press the power button for a long time.
It is usually enough to hold the power key for a period of time. 10-20 If the device reacted with a vibration or a logo, it means that the problem was the software freeze. In some cases, a combination of buttons is required: press the Volume Up and Power simultaneously.
- 🔘 Press the switch on 15-20 seconds before the Mi logo appears.
- 🔋 Turn off the charger before trying to reboot.
- 📱 If there is a case, remove it to exclude the clamping of the buttons.
- 🔌 Try connecting your phone to your computer through USB-cable.
A common cause of cyclic reboots is sticking the power button itself, and if the button mechanism is damaged or dirt is trapped, it can permanently close the contact, causing the phone to turn on and off, and tapping the body around the button can sometimes help unlock the mechanism.
☑️ Primary diagnosis
Enter Recovery Mode and Reset Settings
If a simple reboot doesn't work, you need to go to Recovery Mode, which is a special diagnostic environment built into the firmware that allows you to control the system bypassing the main interface, where you can clear the cache or perform a complete data reset.
To enter Recovery mode on the device turned off, press the Volume Up + Power key combination. Hold them until the logo appears, then release the power button, while continuing to keep the volume. A multi-point menu should appear on the screen, controlled by the volume buttons, and selected by the power button.
From the Recovery menu, select Wipe Data. Be careful: this step will delete all user data. If you want to try a softer option, choose Wipe Cache, which will not affect your files, but can eliminate update errors.
| Action. | Data retention | Risk | Efficiency |
|---|---|---|---|
| Wipe Cache | Yes. | Low. | Medium |
| Wipe Data | No. | Loss of photos/contacts | Tall. |
| Reboot | Yes. | No. | Verification |
| Connect with MIAssistant | Depends on the PC. | Medium. | Tall. |
After reset, select Reboot -> Reboot to System. The first run can take longer than usual, sometimes up to 5-10 minutes. Do not interrupt the process, even if the screen remains black for a long time.

Using Fastboot Mode for Flashing
When standard methods are powerless, Fastboot mode comes to the rescue, a protocol that allows you to interact with the bootloader directly from the computer, and in this mode you can reflash the phone even if the operating system is completely damaged.
To enter the Fastboot on the phone turned off, press Volume Down and Power. The screen will show an image of a hare repairing an android, or a message that says FASTBOOT. To work in this mode, you will need a computer, USB-cable and utility Mi Flash Tool.
The firmware process requires pre-preparedness, you need to download the official firmware for your particular model from the developer's website, and it's important to choose the Recovery or Fastboot firmware version depending on your skills and the state of the device.
⚠️ Warning: Fastboot flashing can completely erase all data on your device. Make sure you have a backup of important information if your phone is still responding.
After connecting your phone to your PC in Fastboot mode, launch the Mi Flash Tool. Choose the path to the folder with the unpacked firmware and press the Flash button. The process will take a few minutes, after which the phone will automatically restart with the clean system.
💡
Use the original. USB-cable USB 2.0 on a computer for maximum firmware connection stability. USB 3.0 sometimes causes connection errors.
Diagnostics of hardware problems and battery
If the software fails, the problem lies in the physical components, most often the culprit is the battery, lithium-ion batteries degrade over time, losing the ability to keep the voltage under load, and when you try to start the system, the voltage drops, and the phone turns off.
It's also worth checking the charging connector. If the USB port has accumulated dust or it's shattered, the phone may not be getting enough current to turn on. Carefully clean the connector with a dry toothbrush or wooden toothpick, avoiding using metal objects.
- 🔋 Try charging your phone from another power source (Power Bank, another unit).
- 🔌 Leave the device on charge on 2-3 for an hour, even if it does not respond.
- 🌡️ Check the body temperature: overheating can block the switching on.
- 👂 Listen: Does the phone make sounds when connecting charging.
In rare cases, the problem is the departure of the display plume or buttons. If the phone vibrates or makes sounds when trying to turn on, but the screen black may malfunction the screen itself or its plume.
💡
If the phone is warmed in the processor area when connecting to charging, but does not turn on, there is a high probability of short circuit on the board. Further attempts to turn on are dangerous.
When you need to contact the service center
There are a number of situations where self-repair is not only useless, but also dangerous. If after all the manipulations, the smartphone continues to behave unstable, the components of the motherboard are likely to be damaged, this could be a failure of the power controller or memory.
The situation is particularly critical if the device has been flooded with liquid, the contacts corrosion does not occur instantly, but over time, and even if the phone is turned on after drying, oxidation can continue, leading to irreversible consequences.
Also, you should not open the device if it is under warranty. Infringement of seals and autopsy marks automatically deprive you of the right to free repairs.
⚠️ Warning: A billowing battery is a fire hazard. If you notice that the back of the phone has bent or the screen has gone in waves, immediately stop charging and dispose of the battery.
Professional diagnostics at the service center will take less time and save you nerves. The masters use special equipment to check the current consumption and accurately identify the faulty node. In some cases, it is cheaper to replace the entire board than to repair individual chips.
