Xiaomi is endlessly rebooting: what to do and how to save the smartphone

The situation of Xiaomi smartphone endlessly rebooting, forcing the owner to observe the Mi or Redmi logo every few seconds, is one of the most stressful for the user.This behavior of the device, often called a "bootloop" or cyclic reboot, can be caused by both a software failure and a serious hardware malfunction. In most cases, panic early: the Android system could damage system files after a failed update or due to a lack of memory.

Primary diagnosis requires calmness and consistent action. If your Xiaomi or Redmi phone goes into reboot, it means that the operating system cannot properly complete the initialization process of components. It is important to determine the moment when problems began: after a fall, moisture or installation of a questionable application, this will depend on the strategy for restoring the functionality of the gadget.

The next steps depend on whether the device responds to commands or is completely locked in the loop. We will look at methods from simply removing the battery (if possible) to deep flashing through the computer. It is critical not to try to charge the device in a loop indefinitely, as this can lead to overheating of the power controller and bloating of the battery.

Primary diagnosis and elimination of sticking buttons

Before we go to complex software methods, we need to rule out the banal physical reasons. Often, the Xiaomi phone reboots due to sticking of the on button or volume. The security glass, case or banal dirt can create constant pressure on the mechanical switch, making the system think that the user is holding the button pinched.

Remove the protective case and carefully examine the ends of the device. Try to gently press the switch several times, listening to the characteristic click. If the button is difficult to move or it does not return to its original position, the problem is solved by cleaning or replacing the plume. In some cases, gently tapping the body on the palm (without fanaticism) helps to release the stuck mechanism.

⚠️ Warning: If the device has recently come into contact with water, do not attempt to charge it or dry it with a hair dryer. moisture inside the case when the voltage is applied will cause a short circuit, which will turn the software failure into an irreversible failure of the motherboard.

Also worth checking is the status of the charging connector. Oxidation of contacts or pile can cause voltage surges, which are perceived by the system as a signal to reboot. Carefully clean the USB-C port with a wooden toothpick or compressed air. If after these manipulations the reboot cycle has not stopped, then we go to software methods.

Attempting to enter Recovery mode

Recovery mode is a diagnostic environment written into a separate partition of the phone’s memory, independent of the main operating system. If the Xiaomi phone is endlessly rebooted, logging into Recovery often allows you to reset the cache or perform a factory reset. To log in, you need to turn off the device completely (if it turns on) or wait for the screen to fade in the loop.

Press both the volume button and the power button at the same time. Hold them until the Mi or Redmi logo appears, then release only the power button, while continuing to keep the volume. If everything goes well, you will see a menu with English text and a few points. The navigation is done with the volume buttons, and the selection is with the power button.

In the Recovery menu, you are interested in Wipe Data. However, before you complete a reset, try to find the Wipe Cache option (if available in your version of Recovery).Cache cleaning won't delete your personal files, but can fix the temporary file errors that cause the crash. If cleaning the cache didn't help, you'll have to go to drastic measures.

Selecting Wipe All Data will completely delete all information from the internal drive. This is an irreversible operation. If you did not have a backup in the Mi Cloud or Google cloud, the data will be lost. Once confirmed, the system will begin a cleanup process, which can take several minutes. Once completed, select Reboot -> Reboot to System.

Using Fastboot Mode for Flashing

If Recovery doesn't work or Xiaomi's phone doesn't come in, Fastboot is still a low-level protocol that lets you interact with your device's memory directly through your computer, USB-Good quality cable and Mi Flash Tool. You also need to download the official firmware for your particular model.

To log into Fastboot on a device turned off, press the volume button and plug in USB-The screen should show a hare in a hat-eared, repairing an android, with the inscription FASTBOOT. If the device enters this mode and does not leave it spontaneously, then the hardware is most likely intact, and the problem lies in the damage to the system partition.

The process of firmware through the Mi Flash Tool requires care. Unpack the archive with the firmware, open the program, click the "Select" button and specify the folder with the files. Press "Refresh" so that the program sees the connected phone. At the bottom of the window, it is important to choose the clean all mode (complete cleaning) or clean all and lock (clean and lock the bootloader, only for the original firmware).

Press Flash and wait until the process is over. It's strictly forbidden to turn off the cable or interrupt the computer's power. If there's an error in the process, try replacing it. USB-cable or switch to another port USB 2.0 Successful firmware will return the phone to factory condition.

Memory problems and storage overflow

One of the common reasons why Redmi or Xiaomi is going into a reboot is a critical overflow of internal memory.When free space is nearing zero, the Android operating system cannot create the temporary files and logs needed to work, leading to crashing processes and restarting.

In this case, standard menu login may not be possible. Try to enter Recovery mode and perform a data reset as described above. This is the only way to free up space if the phone does not boot. In the future, make sure that at least 10-15% of the total storage remains free.

There is also a risk of damage to the physical drive (eMMC or UFS). If the memory has broken sectors, the phone may try to read the system file, stumble upon an error, and restart. In such cases, software methods are often powerless, and a replacement of the memory chip in the service center is required.

To prevent memory problems, use built-in MIUI shell cleaning tools or third-party utilities like Files by Google. Regularly remove the cache of heavy apps like Telegram, WhatsApp and social networks, as they tend to grow to gigabytes of junk files.

Hardware malfunctions: battery and motherboard

If software methods, including flashing and resetting, have failed, there is a high probability of hardware failure. An old or bloated battery may not produce the necessary current at the time of peak load (start of the system), which causes a voltage drop and reboot. You can check this by connecting the phone to a powerful charger: if the charger is stable, and without it it reboots, the problem is in the battery.

A more serious problem is the chip dump or memory. Xiaomi smartphones use BGA technology, where chips are soldered with solder balls. When you fall or overheat, contact can be disrupted. The symptoms are often not only reboots, but also artifacts on the screen, the touch panel hanging before turning off.

Another hidden cause may be a short circuit in the power supply caused by a microcrack on the board, in which case the phone may be kept off when charging, and if you feel a strong heat in the CPU area when you try to turn on, further attempts to start the device may cause it to burn up completely.

Prevention and safe use of MIUI

To minimize the risk of encountering a situation where Xiaomi phone is endlessly rebooted, you should follow the rules of digital hygiene. Avoid installing applications from unknown sources, especially those that require advanced access rights. Often it is the viruses-miners or advertising modules that cause instability of the system.

Update your operating system regularly. Although newer versions of MIUI sometimes contain bugs, they also include security fixes and memory optimization. Always back up important data before major updates. Use cloud services or sync with your PC.

💡

Use original chargers. Cheap analogues can produce unstable voltages that damage the power controller over time and cause chaotic reboots.

Keep the battery from running too low. If the phone is dead, charge it as soon as possible. Prolonged storage of a discharged device leads to degradation of battery chemistry, which eventually manifests itself in sudden shutdowns even when charged.

💡

Regular smartphone maintenance, including memory cleaning and update checks, extends the life of the device and reduces the risk of software failures by 80%.

In conclusion, it is worth noting that most problems with cyclic reboot are solved software. However, if you are not confident in your abilities when working with the Fastboot or disassembling the device, it is better to turn to professionals. Independent experiments with a soldering iron or aggressive chemistry can finally finish the gadget.
