The situation when Xiaomi smartphone suddenly stops loading the operating system and begins to restart indefinitely, is familiar to many users. The screen goes out, then lights up with the logo "Mi" or "Redmi", and this cycle can last for hours. In the technical environment, this phenomenon has become known as a boot loop - a cyclic reboot that prevents the device from fully initializing all system services.
It's not a good idea to panic at this point, although it's natural to want to bring your gadget to the service center right away. Often the problem is a software failure that can be fixed on your own with a minimum of knowledge and tools. Understanding the nature of the reboot cycle is the first step to successfully restoring your smartphone or tablet to health.
In this article, we will go into detail about why Xiaomi gets into such a state, how to distinguish a software failure from a hardware failure, and what proven treatments exist. We will go from simple actions like turning off buttons to complex firmware procedures through Fastboot.
Causes of cyclical reset
Before you start resuscitating a device, you need to understand what caused the boot failure, and the reasons can range from a trivial memory shortage to critical errors in the file system, and users often provoke the problem by installing questionable applications or interrupting the firmware update process.
One common cause is a system file conflict after a failed file. OTA-If the battery runs out or the network fails when you download and install new software, system partitions can be damaged, and bootloops are often experimented with obtaining Root rights or installing custom recoveries without proper preparation.
Hardware factors can also be ignored: Damage to the power button plume, battery bloating, or failure of the power controller can also cause spontaneous reboots, which the user takes for a software bootloops, in which cases software methods may be powerless.
- 📱 Damage to system files after a failed update or crash.
- 📱 Installed software conflict or malicious applications.
- 📱 Internal memory overflow that blocks the system.
- 📱 Hardware malfunctions of the switch or plume button.
⚠️ Warning: If the phone fell into the water or was hit hard shortly before the problems occurred, the probability of hardware failure increases significantly.
Primary diagnosis and simple solutions
The first thing to do when you detect a reboot cycle is to eliminate external factors. Often, the cause is a sticky on button or volume button. The case can press the keys, creating a permanent closure of the contact, which is perceived by the system as a command to reboot or enter recovery mode.
Take off the cover and inspect the case carefully. Try pressing all the physical buttons several times to stir the mechanism up if it's stuck. If you have the skills and tools, you can gently disassemble the back cover and temporarily disable the button plume from the motherboard. If the phone then boots up safely, the problem is found.
Another important aspect is battery power. With a critically low charge and a faulty battery, the phone may try to turn on, go into defense and turn off again. Leave the device on charge for at least 30-40 minutes, even if the screen does not light up. Use the original cable and power supply, as unstable voltage also causes failures.
If simple methods didn’t work, try recovery mode, which usually requires you to press the volume button and the power button at the same time. If you managed to get into the Recovery menu (where there are a selection of languages and menu items), then the underlying system is intact, and the problem is most likely in user data or cache.
- 🔋 Leave your phone on charge for 1 hour without intervention.
- 🔋 Remove the case and check the progress of the volume buttons and switching on.
- 🔋 Try connecting the device to your computer – whether it responds with sound?
💡
If the phone reacts to the PC connection with sound or vibration, but the screen is black or on the logo is a good sign. The computer sees the device, then the processor and some of the controllers are alive.
Using Recovery Mode for Resetting
Recovery mode is an integrated recovery environment that allows you to service your phone independently of the main operating system, and that's where the key to solving a problem if it's caused by a software failure is accessed by a keyboard combination when the device is off.
Once you're on the menu, you'll see a list of options. We're interested in Wipe Data or Clear Data. It's important to understand that doing this will completely delete all user data, including photos, contacts and apps. However, in a bootloom situation, this is often the only way to save the phone from going to the service.
Select Wipe All Data and confirm the action. The system may ask you for consent several times, requiring you to press "Confirm." Once the cleaning process is complete, select Reboot -> Reboot to System. The first download can take up to 10-15 minutes, do not be afraid of a long wait.
☑️ Checklist before data reset
⚠️ Note: The “Wipe Data” feature in Xiaomi’s stock Recovery often requires you to enter the screen unlock password or the password from your Mi Account. If you forget this data, a standard reset may not be available and you will have to use Fastboot mode.
Fastboot mode and flashing the device
If resetting via Recovery is not possible or helpful, Fastboot mode comes to the rescue, a low-level protocol that allows you to interact with the device bootloader directly, and it is through Fastboot that the “official” way is reflashed, which is the most reliable method for treating complex software bootloops.
To enter this mode, you usually need to press the volume button and connect the USB cable to the computer, and the screen will show an image of a rabbit repairing an android, or the inscription FASTBOOT. If the phone enters this mode and holds it, then the bootloader is intact.
For firmware, you need the Mi Flash Tool and the official firmware in.tgz (for Fastboot) rather than.zip (for Recovery). You need to download the firmware from the official website, unpack and point the way to the folder in the program. It is important to choose the correct firmware mode: Clean all (full cleaning) or Clean all and lock (clean and lock the bootloader).

fastboot rebootThe firmware process takes 5 to 15 minutes, and you can't turn off the USB cable at that time, and if it's successful, the phone will automatically reboot to the clean system.
- 💻 Download Mi Flash Tool from the official developer website.
- 💻 Find firmware for your model (model code is important!).
- 💻 Install the drivers. ADB and Fastboot on the computer.
- 💻 Select the Clean All mode to ensure error elimination.

Table of error codes and loading statuses
When you try to download or firmware, the device can give different indications, and understanding what the screen or computer is showing helps you diagnose the stage at which the failure occurs.
| Status/Indication | Description of the problem | Possible solution |
|---|---|---|
| Mi logo (infinitely) | Failure of system files, damage to the data partition | Wipe Data in Recovery or Flashing |
| Hare with an android (Fastboot) | Accidental hitting in firmware mode | Hold the power button 15 seconds |
| Black screen + vibration | Display problem or critical kernel failure | Connection to PC, checking Device Manager |
| Red Castle (Locked) | bootloader locked, firmware not signed | Use the official firmware |
| Orange state ( unlocked ) | The bootloader is unlocked, the system is changed | Firmware through Fastboot with cleaning |
Analyzing the behavior of the device on these grounds allows you to narrow the search for a problem, for example, if the phone vibrates, but the black screen may have burned the backlight or plume, rather than the system bootloop.
💡
If a computer defines a device as “QDLoader” or “Qualcomm” without installing drivers, it is an EDL mode. It requires an authorized account for firmware and is solved only in the service.
Hardware problems: when software is powerless
Remember that Xiaomi, like any other technology, is subject to physical wear and tear. If software methods, including full flashing, fail, the problem lies in the hardware. Most often, the bootloop gets a memory (eMMC or UFS), which has exhausted the life of the rewrite cycles.
Also common is a chip dump or a memory chip due to falls, and microcracks in soldering can appear and disappear when heated, causing unstable operation, and in such cases only warm-up (rebolling) in a service center helps, but this is a temporary measure.
Another hidden enemy is the oxidation of contacts after moisture hits. Even if the phone was dry, corrosion could reach important power chains. Visual examination of the board under a microscope often reveals green plaque or broken tracks.
- 🔧 Depreciation of internal memory (the phone was slowed down before death).
- 🔧 CPU dump due to fall or overheating.
- 🔧 Oxidation of the board after contact with liquid.
- 🔧 Failure of the power controller (PMIC).
⚠️ Warm up the processor with a hair dryer at home is an extremely risky operation. You can finally overheat the crystal or melt the plastic elements of the case, depriving yourself of the right to warranty repairs.
Data prevention and protection
To minimize the risk of being in the bootloops in the future, you should follow certain operating rules, first of all, avoid installing applications from unknown sources that may contain malicious code that modify system files.
Back up important data regularly. Xiaomi’s ecosystem has built-in sync with Mi Cloud, and the ability to create a local copy through the settings menu. Store important photos and documents on Google Drive or Yandex.Disk.
Don’t interrupt the system update process. If you see a message about an available update, make sure that the battery is above 50%, and do not touch the phone until the full reboot. Also, do not fill the internal memory “on the back” – the system always needs free space for temporary files and cache.
💡
Install an app to monitor battery health and memory. A sharp drop in recording speed or temperature spikes can portend a device that will soon fail.
