Xiaomi is constantly rebooting: diagnosis and elimination of bootloop

The situation where your Xiaomi or Redmi suddenly starts to reboot endlessly, causing the screen to go out and light up again, is familiar to many users. This phenomenon, often called bootloop, can occur at the most inopportune moment: after a failed system update, installing a questionable application, or even after a device falls on a hard surface, you should not panic in this situation, since in most cases the problem is solved by software methods without contacting the service center.

Before you carry the gadget for repair, you need to conduct an initial diagnosis to understand the nature of the failure. Most often, the device hangs on the Mi or Redmi logo, or simply flashes the screen, not allowing you to get into the menu. Cyclical reboot indicates that the Android operating system or bootloader can not correctly complete the process of initialization of the hardware. Understanding what caused the failure will help you choose the right strategy for restoring the smartphone.

In this article, we will take a look at all possible causes of the problem, from software conflicts to physical damage to the motherboard, learn how to safely enter Recovery mode, perform a full data reset or reflash the device using a computer, and act consistently and carefully so as not to aggravate the situation and lose important information, if possible.

Primary diagnosis and simple solutions

The first thing to do if Xiaomi is starting to behave incorrectly is to rule out trivial external factors. Often the cause of strange behavior is a stuck power button or a damaged charging cable that creates voltage surges, perceived by the system as a signal to reboot. Carefully examine the connectors and check if the switch on button falls inside the case.

If the physical elements are OK, try a forced reboot, which helps to reset static electricity and clear temporary errors in RAM. Press the power button and hold it for 10-15 seconds until the screen goes out and the device vibrates. If this doesn't work, the key combination may vary depending on the model.

💡

If your smartphone responds to touches before the next reboot cycle, turn on flight mode immediately.This will turn off network search, which is often the trigger for system failures when software crashes.

In some cases, the problem is in a non-compatible accessory. USB-devices, remove SIM-MicroSD card and memory card: A damaged file system on the memory card can block the operating system from booting, causing the phone to go on an endless cycle.

• 🔋 Check the originality and integrity of the charging cable and power supply.
• 🔘 Make sure the power button is not stuck in the pressed state.
• 💿 Extract. SIM-Memory card and card to avoid equipment conflict.
• 🌡️ Allow the device to cool if it was overheated before failure.

⚠️ Warning: If the phone is hot to the touch and smells of burnt plastic, stop turning on immediately.This may indicate a short circuit in the power supply chain, and further action may lead to a fire.

Enter Recovery Mode and Reset Settings

If simple methods don’t work, you’ll have to take more serious measures through the Recovery Mode recovery menu, a special mode built into the firmware that allows you to control the system bypassing the main bootloader, and to log in on a device that is turned off (or when it is in a reboot cycle), you need to press the power button and Volume Up volume button simultaneously.

When the Mi logo appears, release the power button, but keep the volume down until the Main Menu appears. The navigation is done with the volume buttons and the power button is the choice. You need to find the Wipe Data item. In the newer versions of MIUI and HyperOS, this process needs to be confirmed, as it will completely destroy all user data.

Select the Wipe All Data option and confirm the action. The formatting process can take a few minutes. Once complete, the system will prompt you to return to the main Back to Main Menu menu, where you need to select Reboot and then Reboot to System. The first run after the reset will be long, as the system will create new partitions and configuration files.

Problems with system updates and firmware

One of the most common reasons Xiaomi is constantly rebooting is a failure when updating the operating system: If the power is lost during the download or installation of the service pack or the Internet connection is interrupted, the system files may be damaged, in which case the bootloader cannot find the necessary components to start Android.

To solve this problem, you will need a computer and the official utility Mi Flash Tool or Xiaomi. ADB/Fastboot Tools. You need to download the current firmware version for your particular model from the official website. It's important to choose the type of firmware Recovery or Fastboot, but not the one you want to use. OTA, The latter are designed to update via the phone menu.

If you decide to use Fastboot mode, connect the phone turned off to your PC by holding down the Volume Down Volume Down button. The screen will show an image of a hare repairing an android. Launch the Mi Flash Tool, select the folder with the unpacked firmware and press the Flash button. Make sure that Clean All mode is selected to avoid conflicts between old files and the new system.

💡

Use only the originals. USB-cables and ports USB 2.0 on the computer motherboard (back of the system unit), as the front ports often do not provide stable power for firmware.

Application conflicts and malicious software

Sometimes the culprit is a third-party application that was installed shortly before the problems occurred, such as a memory optimizer, a modified launcher, or a program that requires deep access rights. Malware can block system processes, causing the Android Kernel to crash.

If the phone is turning on and you see the desktop, try going to Safe Mode. To do this, press the off button, and when the off icon appears on the screen, keep your finger on it for a long time (or on the off icon) until the prompt to go to Safe Mode appears. In this state, only system applications are downloaded.

If the reboots have stopped in safe mode, it means that the problem is definitely with third-party software. Remember what you installed recently, and remove suspicious programs. Pay special attention to applications that have the right to change system settings or access the screen over other windows.

• 🛡️ Scan the device with built-in antivirus Security.
• 🗑️ Remove all apps installed from unknown sources (not from Google Play).
• 🔄 Disable or remove newly installed widgets and live wallpaper.
• 📉 Check the battery usage statistics – a failed app may be missing or have a strange name.

⚠️ Warning: Avoid installing applications to “speed up the internet” or “cool down the processor” from unverified sources. These often contain ad modules that load the system and cause cyclical reboots.

Hardware malfunctions and battery problems

When the software methods are exhausted and Xiaomi is still restarted, there is a high probability of physical failure. Battery wear is a common cause. If the battery can not produce the necessary current at the time of peak load (for example, when the camera or modem starts), the voltage drops, and the phone turns off or restarts.

If the phone had previously fallen, the connectors of the display or the power button plume could have moved away from the board. In some models, such as the Redmi Note series or the Mi with a plastic case, the unstick battery can push on the board, causing the contacts to close.

Check the charging connector. If it has accumulated dust or oxidation, the phone may not correctly detect the charger's connection, constantly switching between charging and battery modes, causing the interface to reboot. Carefully clean the connector with a wooden toothpick without using metal objects.

Use of Fastboot and EDL mode

For advanced users who have encountered a brick, the EDL (Emergency Download Mode) mode is a deep service mode that allows you to reflash the device even when the bootloader is damaged, and logging in often requires disassembling the phone and closing special contacts on the board, or using special ADB commands.

This mode requires Mi Account rights with authorization levels that only authorized service centers have. However, there are workarounds and paid services that allow you to flash your device in this mode. If you see a black screen image of a cable labeled Fastboot or just a black screen when you connect to a PC (Device Manager shows Qualcomm HS-USB QDLoader 9008), then you are in this mode.

Using the Fastboot command line allows for point-by-point actions with partitions of memory. However, inexperienced users should not experiment with write commands (flash) without clearly understanding which partition is responsible for what, an error can lead to a complete loss of IMEI and network functionality.

💡

Before any manipulations with Fastboot or EDL, be sure to install Qualcomm and Xiaomi USB Driver drivers on your computer, otherwise the system will not see the device in the desired mode.
