Xiaomi is constantly rebooting: what to do and how to fix

When your Xiaomi or Redmi suddenly starts to reboot indefinitely, it can cause panic.This phenomenon, often called bootloop, turns the device into a useless piece of plastic and metal, preventing even unlocking the screen. The device can turn on before the Mi or Redmi logo, then go out again and start the cycle anew, the reasons for this behavior range from the banal sticking of a button to critical damage to system files.

In most cases, the problem lies in a software failure that occurred after a failed update, installation of a poor application or overflow of internal memory. However, hardware malfunctions such as battery wear or damage to plumes cannot be excluded. It is important to remain calm and methodically check all possible options, starting with the simplest actions that do not require deep technical knowledge.

Before you bring your gadget to the service center, you should try a number of standalone solutions. Often, cyclical reboot is eliminated by forced reset or logging into a special engineering menu. In this article, we will discuss in detail the algorithms of actions for different scenarios so that you can bring your smartphone back to life without unnecessary costs.

Diagnostics of hardware causes: power button and battery

The most common, but common, cause of endless reboots is mechanically sticking the power button. If the Power button is clamped or damaged inside the case, the system perceives this as a constant reboot signal. Carefully examine the end of the device: the button must have a clear, elastic stroke and click. If it fails or goes too tight, this is likely the problem.

The second important aspect is the state of the power supply: old or substandard batteries may not provide the necessary current at the time of peak load at start-up, which leads to instant shutdown and a new cycle of on-set, and it is also worth checking the originality of the charger: cheap analogues often can not provide the stable voltage required to load MIUI or HyperOS.

• 🔍 Visually inspect the on button for physical damage or contamination.
• 🔋 Try connecting your phone to another, known to be a serviceable charger and cable.
• 🌡️ Feel the case: If the device overheats strongly, it could be a sign of a short circuit or failure of the power controller.

⚠️ Warning: If you notice a bloated back cover or screen, do not attempt to charge the device or disassemble it yourself.The bloated battery is fire-prone and requires immediate replacement at the service center.

Sometimes the problem is solved by a simple but effective "light kick" method, by tapping your finger on the end of your smartphone carefully but surely at the power button, which can help to separate the stuck contacts, and if the cycles stop after that, then the cause was mechanical, and the button will still have to be replaced soon.

Forced reboot and entry into Recovery mode

If the hardware buttons are OK, the next step is to try to programmatically reboot the system. Standard shutdown in this state is impossible, so you use the Hard Reset button. Press the Volume Up and the power button at the same time. Hold them for about 10-15 seconds until the screen goes out and the logo appears.

If a simple restart didn't work, you need to get into the Recovery menu. This is a special mode built into the phone's memory that allows you to control the system even when the main OS is not working. To log in to most Xiaomi models, you need to press the volume button and the power button at the same time. When the logo appears, the power button can be released, continuing to hold the volume until the menu appears.

In the Recovery menu, the volume buttons (up/down) control the menu, and the power button confirms the choice. You need to find Wipe Data or Factory Reset. This action will completely delete all user data, but is often the only way to get out of the reboot cycle caused by a software conflict.

After the reset, the system will suggest a reboot. The first run can take longer than usual - up to 5-7 minutes. Don't worry, if the logo hangs for a long time, this is the process of initial configuration of the file system.

Resolving memory problems and storage overflow

One of the hidden reasons why Xiaomi reboots without stopping is a critical overflow of internal memory: When the free space runs out completely, the Android operating system cannot create the temporary files and logs needed to run, leading to crashing processes and restarting.

If you can get to a desktop or menu for even a few seconds, immediately clear space, delete heavy videos, unneeded apps, or move files to the cloud, and in some cases, clearing the cache through storage settings helps, but if the phone doesn't even unlock, this method won't work without a complete reset.

There is also the concept of junk files in the system partition that are not deleted by conventional methods, which can accumulate after many updates or installing “heavy” interface modifications. They require superuser rights to delete them, but it is impossible to obtain these rights on a working phone in the reboot cycle.

So if you suspect a memory overflow but can't delete anything, the only option is formatting through Recovery, which is guaranteed to clear the space, but will require you to restore data from a backup if you had it created in your Google or Mi Cloud account.

Failure after firmware update: what to do?

Often, the problem occurs immediately after an OTA update, if the Internet connection is interrupted or the battery is down during the boot process, the new firmware files may become corrupted, as a result of which the phone tries to start the incorrect version of the OS and goes into restart.

In this case, simply resetting the settings may not be enough, as the system files themselves are damaged. You will need to flash the device. For Xiaomi models, there is an official Mi Flash Tool that allows you to restore factory firmware through your computer. This is a more complex method that requires a PC and USB-cable.

• 💻 Download the official firmware for your model from the site miui.com (Download section).
• 🔌 Install the drivers. ADB and Fastboot on the computer.
• 📱 Transform your phone to Fastboot (Volun Down and Power).

⚠️ Warning: Fastboot flashing completely erases all data. Make sure you choose the right model of the device, as firmware from another smartphone can permanently disable the gadget ("brick it up»).

If you don’t have experience with the firmware, it’s best to consult a specialist.Incorrect actions in Fastboot mode can block the bootloader or change regional settings, which will make it impossible to use some functions, such as NFC or calls.

Application Conflict and Safe Mode

Sometimes the culprit is a third-party application that conflicts with the system, often after installing programs from unknown sources or modified versions of popular services, and to test this hypothesis, you should try to start the phone in Safe Mode.

This mode only downloads system applications. If the phone is stable in Safe Mode and does not restart, then the problem is exactly in the software. You will need to find and remove newly installed applications. Usually, this mode is logged in via the off menu (long press on the "Stop" button on the screen), but if the screen does not respond, this method is not available.

💡

If you can't enter Safe Mode through the screen, try quickly pressing and holding the volume button when you download the logo, and on some models, this forcefully turns Safe Mode on.

Deleting a problem application often solves the problem, and paying special attention to memory cleaners, antiviruses and launchers that have deep access to the system, and checking if there have been recent updates to installed applications that may have caused the failure.

Even if the cycles continue in safe mode, the probability of hardware failure or damage to the system partition increases by up to 90%, in which case software treatments will not help, and deeper intervention is required.

When a service center is needed: hardware breakdowns

There are a number of symptoms that indicate that software methods are powerless: If the phone is warming off when connected to a charge, makes extraneous sounds or has physical damage (cracks, traces of water), self-repair can only make the situation worse.

A common problem with Redmi's budget models is that the plume or microcracks on the board will fall, and in such cases contact will disappear when heated or vibrating, causing a reboot, and the power controller or memory (eMMC/UFS) may fail, requiring soldering and replacement of components on the board.

• 🌊 Moisture: Even if the phone worked after drying, the contact corrosion could start and progress.
• 🔨 Blows: Microcracks in the soldering of the processor or memory appear over time.
• ⚡ Power surges: Using unoriginal charges could damage the power chain.

At the service center, specialists will diagnose the circuit board using special equipment, connecting to the board through a programmer, which will allow you to determine exactly which node is faulty, repairs can range from simple soldering of the charging connector to complex processor rebolling.

You don't have to wait to call the masters if you notice the progression of the problem. Sometimes it's cheaper to replace the battery or clean the moisture on time than it is to replace the burnt motherboard.

Prevention: How to avoid problems in the future

To minimize the risk of cyclical reboots in the future, follow simple rules of operation. Regularly update the system, but do so only with stable Wi-Fi and a charged battery. Do not install applications from dubious sources, bypassing official stores.

Keep your memory status in check: try to keep at least 10-15% of the total free, this will provide the system with room for maneuver and temporary files, and use original or certified charging accessories so that the power surges do not damage the power controller.

💡

Regularly backing up your Mi Cloud or Google Photos is the best insurance against data loss in case of any system failures.

Reboot your phone periodically (once a week) to clean up RAM and reset system processes, a simple procedure that prolongs the life of the operating system and prevents the accumulation of errors.
