A situation where your Xiaomi or Redmi suddenly stops turning on normally and starts to reboot endlessly cyclically, causing panic in the owner, technically called bootloop. This is a state in which the device gets stuck on the Mi or Redmi logo, or turns off and immediately tries to turn on again, without reaching the desktop. The reasons for this behavior can be many: from a banal malfunction in the operating system after a failed update to serious hardware malfunctions, such as battery degradation or memory dump.
It's early to panic in most cases, because software errors make up the lion's share of all treatments for these symptoms. However, ignoring a problem or doing the wrong thing in the first few minutes can lead to loss of important data or exacerbation of a breakdown. You need to have a clear understanding of the sequence of actions to safely bring the gadget out of critical condition. Below we'll discuss algorithms of various degrees of complexity, from simple button manipulation to flashing through an engineering menu.
It's worth noting that modern MIUI and HyperOS shells have built-in protection mechanisms that can block booting when system conflicts are detected. That's why standard on-boarding is often impossible and requires forced intervention in the boot process. It's critical not to try to charge a device during endless reboot cycles if it gets too hot, as this can cause the battery to bloat or damage the power controller. Let's take a look at the step-by-step instructions that will help reanimate your device.
Primary diagnosis and simple solutions
Before we go to radical measures like a complete data reset or flashing, we need to eliminate basic factors that are often overlooked. Sometimes the problem is sticking the on button or conflicting the periphery. If the smartphone body gets moisture or is mechanically affected, the probability of hardware failure increases many times over. First of all, check the charging connector and buttons for debris or oxidation.
Often, a cyclic reboot is caused by a short circuit in the charging circuit caused by a poor-quality cable or power supply. Try disconnecting the smartphone from the network if it is connected and retrieving it. SIM-If a damaged microSD card is present, it can block the operating system from loading as Android tries to read it early in the process.
Another method that often helps with software freezes is forced reboot, which differs from a conventional shutdown in that it breaks the power of the board at the hardware level, dropping a static charge and stopping all processes, which requires you to pinch the on button and hold it for a long time, ignoring the vibrations and appearance of the logo.
- 🔌 Disconnect the smartphone from the charger and remove the tray SIM-map.
- 📉 Press the power button and hold it for 15-20 seconds until it is fully vibrating.
- 🧹 Check the connector. USB for dust and clean it carefully with a non-metallic object.
- 🌡️ Leave the device to lie down for 10-15 minutes to cool down if the case was hot.
⚠️ Warning: If after holding the power button for a long time, the phone vibrates, but the screen remains black, perhaps the problem lies in the display plume or the screen module itself, and not in the system.
If simple methods have not taken action, and the Xiaomi smartphone continues to endlessly reboot, move to deeper diagnostic methods through the system recovery menu.
Enter Recovery Mode and Reset Settings
Recovery Mode is a special diagnostic section built into the memory of the smartphone regardless of the main operating system, you can get into it even when Android is not booting. This is where problems with software conflicts that interfere with a normal start are most often solved. To log in on most Xiaomi and Redmi models, you need to turn off the device (or wait for the screen to go out in the reboot cycle) and pinch the button combination.
The standard combination for logging into stock Recovery is to simultaneously press the Volume Up and Power buttons. Hold them until the Mi logo appears, then release the power button, but keep the volume until the menu appears. The navigation in this menu is done with volume buttons (up/down), and the choice of item is confirmed by the power button. If you have a smartphone with Touch Recovery support, the control will be touch-sensitive.
In the Recovery menu, we're interested in Wipe Data. It's important to understand that choosing Wipe All Data will completely delete all user data, including photos, contacts and apps. However, if the phone is in an endless reboot, often this is the only way to save the device from going to the service center. Before confirming the action, the system may require you to enter a confirmation code that will appear on the screen, which is protection against accidental reset.
☑️ Pre-reset check
After you reset, you need to select Reboot and then Reboot to System, and the first run after the reset can last up to 10 to 15 minutes, as the system recreates the file structure.
- 🔙 Select Wipe Data from the main Recovery menu.
- 🧹 Click Wipe All Data and confirm the action.
- ✅ The message is “Data wiped successfully».
- 🔄 Choose Reboot. → Reboot to System.
Using Fastboot Mode for Flashing
If the reset via Recovery did not help, or the problem arose after a failed update, you will need a more serious tool - the Fastboot mode. This mode allows you to interact with the bootloader of the device directly from the computer, bypassing the operating system. Through Fastboot you can not only reflash the smartphone, but also check the status of the bootloader, which is important to understand whether it was previously unlocked by third-party methods.
To enter Fastboot mode on the device turned off (or at the time of restart), you need to press the Volume Down button and connect the cable. USB, It's connected to a computer, and it'll show a picture of a hare repairing an android, and it'll say, FASTBOOT. To work you will need a PC with Windows, installed drivers ADB/Fastboot Mi Flash Tool or console commands.
The firmware process requires you to download the official firmware for your particular model. It is important to choose the right firmware type: Recovery (update without loss of data if the version allows) or Fastboot (full flash with cleaning). The device in bootloop most often requires a Fastboot firmware with the.tgz extension. After unpacking the archive and connecting the phone, in the Mi Flash Tool utility, you need to choose the path to the firmware folder and press the Flash button.
Risks of an unlocked bootloader
During firmware, it is strictly impossible to turn off the cable. USB Or you can interrupt the process, or you can get a brick, a device that doesn't respond to any commands. USB-The port is good. You'd better use the ports on the back of the system unit directly on the motherboard.
| Parameter | Recovery mode | Fastboot mode | Safe Mode mode |
|---|---|---|---|
| Appointment | Reset, update | Fixing, repairing | Finding the culprit |
| Access to files | No. | No (only via ADB) | Yes (systemic only) |
| Risk of data loss | High (at Wipe) | Critical (always) | Low. |
| Difficulty | Low. | Tall. | Low. |
Safe mode and diagnostics of applications
In some cases, Xiaomi’s smartphone reboots not because of system files, but because of a conflict with a newly installed app. If you manage to get to the desktop for even a short time or see the lock screen, you can try to log into Safe Mode. In this mode, only system applications are downloaded, which allows you to diagnose a software conflict.
To enter Safe Mode on MIUI, you usually need to press the turn off button on your desktop and then hold the Turn off icon on the screen for a long time until you get a suggestion to go to Safe Mode. Alternatively, when you turn on the phone when the Mi logo appears, press the Volume Down button and hold it until you fully boot. If the cyclic reboot stops in Safe Mode, then third-party software is to blame.
In this case, you need to remember which applications were installed or updated before the problem occurred. Go to Settings → Apps → All applications and remove suspicious programs. Particular attention should be paid to memory cleaners, third-party launchers and applications to change the interface, as they have deep permissions to the system.
- 🛡️ Boot in Safe Mode to check system stability.
- 🗑️ Remove the latest installed applications, especially SEOs.
- 🚫 Turn off automatic app updates on Google Play.
- 🧹 Clear the cache of problematic applications through settings.
⚠️ Warning: If the phone is stable in Safe Mode but the problem returns after a normal reboot, don’t ignore it.This is a sure sign that one of the background apps is causing a Kernel Panic crash, which in the long run can damage the file system.
Hardware causes and battery problems
When the software is exhausted and Xiaomi is still going into an endless reboot, the probability of hardware failure is high. One of the most common causes is battery degradation. Over time, lithium-ion batteries lose capacity and can not produce the current needed to start the processor at peak load moments. The phone tries to start, power consumption rises sharply, the voltage drops, and the protective circuit turns off the power, after which the cycle repeats.
Also worth noting is the power button. In models with mechanical buttons (especially in the Redmi Note series and budget Mis), contacts can oxidize or stick. If the button is stuck when pressed, the phone will perceive this as a command to constantly restart or turn on. Careful tapping of the case or repeatedly pressing the button sometimes helps temporarily unlock the mechanism.
More serious problems are associated with overheating of the processor or the collapse of memory chips (eMMC/UFS). This often happens after falls or prolonged overheating (for example, playing in the sun or using during fast charging). In such cases, only heating the chip in the service center (rebolling), but this is a temporary measure. If the phone reboots exactly when connecting to Wi-Fi or starting the camera, the problem is almost certainly in the hardware.
You can use the Engineering Menu mode to diagnose the battery if you can get into it. Type ##6484## in the Phone app. If the phone is responsive to input, check the battery voltage. If it jumps or shows values below 3.6V under load, replacing the battery will solve the problem.
Prevention and preservation of data
To avoid a situation where Xiaomi is endlessly rebooted, it is important to follow the rules of operation and regularly make backups.Mi Cloud or Google Drive cloud service allows you to save contacts, photos and settings so that in the event of a critical reset, you do not lose important information.
Also, don't neglect the official system updates, but it's not recommended to rush to install them in the first days after the release. Often, in early versions of new MIUI builds, there are bugs that are fixed in subsequent patches. If you use custom firmware or an unlocked bootloader, always have an original image at hand to return to the stock state.
Regularly cleaning your smartphone’s memory of junk files and unused applications reduces the burden on the file system and reduces the risk of reading errors. Try not to fill the device’s internal memory by more than 85-90%, as a lack of free space for system files can lead to Android stopping processes correctly and going into a reboot cycle.
💡
Use the Second Space feature to test questionable applications. If the application causes a crash, the main space will remain unaffected, and you can simply remove the second space.
Temperature is another key factor: Don't leave your phone in the sun, on the dashboard of your car, or near the heater, and overheating is the main enemy of electronics, which accelerates the aging of components and can lead to irreversible changes in soldering structure.
💡
Regular data backup is the only guarantee that an endless reboot won’t be a disaster with the loss of photos and documents.
