When a beloved Xiaomi or Redmi smartphone suddenly stops turning on normally and starts to reboot indefinitely, it can catch anyone by surprise.This phenomenon, often called bootloop, turns the device into a useless piece of plastic and metal, causing panic at the risk of losing important photos and contacts. Most often the problem lies in a software failure that blocks the normal load of the MIUI or HyperOS operating system.
Sudden interruption of the upgrade process, overflow of the system partition or conflict of newly installed applications can disrupt the integrity of the bootloader. You should not immediately carry the gadget to the service center, since in many cases you can resuscitate the device yourself using hidden recovery menus. It is important to maintain composure and follow instructions consistently so as not to aggravate the situation.
Before you start to act, you need to understand what caused the failure, because it depends on the choice of recovery method. If the phone began to behave strangely after installing dubious software or interrupted firmware, the chances of success are high. In the case of physical damage after a fall or moisture, the algorithm of actions will be completely different and require the intervention of specialists.
Diagnostics of the causes of cyclic reboot
The first step in solving the problem is to accurately identify the source of the malfunction, which will avoid unnecessary manipulation of data. Cyclical reboot often occurs because system files are damaged or missing, and the operating system cannot pass the initial hardware check, this can happen after a failed update “over the air” or when trying to obtain root rights to inexperienced users.
Another common cause is hardware conflict, such as sticking a power button or damaging the plume. If the power button is physically clamped inside the case, the phone will perceive this as a command to permanently restart. It is also worth checking the battery status: a critically low charge or voltage surges can cause the device to turn off when you try to start energy-intensive processes.
⚠️ Warning: If the phone falls or comes into contact with water before the problem begins, software recovery methods can be useless and even dangerous to electronics.
For a deeper diagnosis, you can try to enter Fastboot mode by holding down a keyboard. If the phone responds to presses and shows the Mi Bunny logo with an android repairing the robot, then the motherboard and display are probably working, which is a good sign that the problem is localized to the software part or the bootloader.
Forced reboot and check of buttons
The easiest and safest method to try is forced reboot, which helps to reset static electricity and stop the hanging processes that could have blocked the system, by pressing the power button and holding it for a long time, ignoring the vibrations and logo appearances.
Some Xiaomi and Redmi models may not have standard retention, so manufacturers have a special algorithm: You need to press the power and Volume Up buttons simultaneously and hold them for about 10-15 seconds. If the screen is out and the device is vibrating, release the buttons and wait a few minutes to watch the reaction.
If the phone continues to reboot, carefully examine the case for mechanical damage. Often the problem lies in a protective case that can press the control buttons. Remove the case and check if the power button is stuck, pressed with a characteristic click or walks too tight.
💡
Try pressing the power button several times before holding it for a long time – this sometimes helps unlock the mechanical contact.
Enter Recovery Mode and Reset Settings
If a simple reboot doesn’t work, you’ll need to use Recovery Mode.This tool is built into every Xiaomi smartphone and allows you to perform diagnostics, clear cache or completely reset to factory settings. Enter this mode when the phone is turned off by pressing the power button and Volume Up button.
Once the Mi logo appears, you can release the power button, but you need to hold the Volume Up until the menu appears, and the navigation in this menu is done with volume buttons (up-down), and the choice of item is confirmed by the power button. You need to find the Wipe Data or Clear Data item that initiates the cleaning process.
☑️ Preparation for data dumping
Be prepared for the fact that the system will require you to enter a special confirmation code that will be displayed on the screen, this is protection against accidental data dumping by attackers. Once the code is entered, the formatting process will begin, which can take from a few minutes to half an hour, and when completed, the phone will prompt you to restart (Reboot).
⚠️ Warning: Wipe Data permanently deletes all user files, including photos, contacts and installed apps. Make backups regularly to avoid losing important data.
Using Fastboot Mode for Flashing
Fastboot mode is a deeper level of access to the system, allowing you to download new versions of firmware directly from your computer. This is the most effective way to fix errors that occurred when you update the system or damage the system partition. To enter this mode, press the power button and the Volume Down button on the device turned off.
The screen will show an image with an android and the words Fastboot. To work in this mode, you will need a computer with the Windows operating system installed, USB-High quality cable and a special utility Mi Flash Tool. You also need to download the current version of the firmware for your particular model from the official website.
The flashing process requires care, as choosing the wrong file can lead to complete failure of the device. In the Mi Flash utility, you need to choose the path to the folder with the unpacked firmware and press the Flash button. It is important to choose the clean all method to avoid conflicts between old files and the new system.
What if your computer doesn’t see your phone in Fastboot?
Analysis of the compatibility table and versions
When choosing a firmware for recovery, it is critical to consider the region of the device and the current version of Android. An improperly selected version of the software can cause the phone to stop seeing the network or lose the functionality of the camera. Below is a table that helps determine the type of firmware you need depending on the situation.
| Situation | Type of firmware | Region | Risk of data loss |
|---|---|---|---|
| Update of MIUI version | Recovery (zip) | Global (Global) | No (on update) |
| Recovery after failure | Fastboot (tgz) | It is in line with the region | Yes (full reset) |
| The change of region (China to Global) | Fastboot (tgz) | Global | Yes (required) |
| Reverse to the old version | Fastboot (tgz) | Anybody. | Yes (unlocking required) |
Pay attention to the firmware file extension: Recovery uses.zip archives, and Fastboot uses.tgz or.tar. Trying to flash Recovery through Fastboot will cause an error, and vice versa. Always check the device model in settings or on a sticker under the battery (if it is removable) before downloading files.
💡
Use only official firmware from miui.com or xiaomi.com, as third-party builds may contain viruses or unstable code.
When Professional Assistance is Required
There are a number of situations where self-repair is not only useless, but can cause final damage to the device. If the phone heats up in the processor area even when it is turned off, this indicates a short circuit on the board, in which case the power supply can lead to fire or failure of adjacent components.
Also, the reason for contacting the service is the EDL Mode (Emergency Download Mode) error, if it occurs constantly and requires an authorized account for firmware. Some new Xiaomi models have protection against unauthorized firmware reflashing, and it is impossible to get around it without special equipment and licenses.
Mechanical damage, such as cracks in the motherboard or oxidation of contacts after entering the water, requires soldering and replacement of components under the microscope, and software methods are powerless here, because the connections between the circuit elements are physically disrupted.
Prevention of disruptions in the future
To minimize the risk of a repeat of a never-ending reboot, you should follow a few simple rules of operation: first of all, avoid installing applications from unknown sources, as they may contain malicious code that damages system files.
Keep an eye on the internal storage space. When the memory is 95-98% full, the system starts to run unstable, which can lead to cyclical reboots. Periodically clean the cache and delete unnecessary files using built-in optimization tools.
Use original chargers and cables. Cheap analogues can produce unstable voltages, which negatively affects the power controller and can cause the device to reboot chaoticly during charging.
