The situation when Xiaomi smartphone is endlessly restarted after the system update causes panic in most users. Yesterday the device worked stable, and today the screen goes out, the MI or Redmi logo appears, and the process begins again. This phenomenon, known as bootloop, often occurs due to conflicting versions of software or damage to system files during recording.
The main reason is that the system or data partition is broken, and if the power is interrupted, the Internet is lost, or the drive has broken sectors, the Android operating system can't complete the boot, and the phone tries to start again and again, getting into an endless cycle.
Fortunately, in most cases, a software bug doesn’t mean a physical breakdown. A full reset via Recovery Mode helps to eliminate 90% of cyclical reboot problems. However, radical measures should be taken to try less aggressive recovery methods, which we will discuss in detail below.
The main reasons for system load failure
Understanding the problem helps you choose the right treatment, and most often, a cyclical reboot is caused by incompatibility of user data with the new version of the MIUI shell or HyperOS. When you update through the OTA (over the air), the system tries to adapt the old settings to the new code, which sometimes leads to fatal errors.
Another common reason is the use of informal builds or modified versions of firmware. If you previously obtained root rights or installed custom Recovery, a standard update can block the bootloader or damage security sections. Also consider the state of the battery: if the battery is worn out, it may not be enough voltage to complete the energy-intensive process of installing updates.
And the human factor is not to be discounted, because interrupting the upgrade process, even for a few seconds, often damages the bootloader, and in this case, the phone simply doesn't know which instructions to follow, and it goes into reboot.
⚠️ Warning: If the phone is warming up when it’s off and vibrating constantly after the upgrade, remove it immediately. SIM-This may indicate a short circuit or a critical power controller error.
The table below shows the main symptoms and their probable causes:
| Symptoms. | Probable cause | Difficulty of solution |
|---|---|---|
| Hanging on the MI logo | Damage to system files | Medium |
| Recovery menu in Chinese | Global firmware failure | Tall. |
| Reboot every 30 seconds | Application or cache conflict | Low. |
| Black screen and vibration | Hardware malfunction | Tall. |
Recovery methods without data loss
The first thing to try if Xiaomi is rebooting itself is to enter Safe Mode or clear the cache, which does not affect your personal files, photos and contacts, but can eliminate conflicting processes. To begin, try simply restarting the device by holding the power button for 10-15 seconds, sometimes this helps to interrupt the cycle and start the system normally.
If a simple reboot doesn't work, you need to go to Recovery mode. To do this, turn off the phone (if it turns on) and press the Volume Up and Power buttons at the same time. When the logo appears, release the power button, but keep the volume. In the menu, the navigation is done with volume buttons, and the choice is with the power button.
☑️ Pre-reset check
In the Recovery menu, find Wipe Cache. Don't confuse it with Wipe Data! Cache cleanup removes temporary update files that may have been corrupted. After you run the command, select Reboot. If the system boots, the problem is solved. If not, you'll have to move on to more serious measures.
Full reset via Recovery Mode
When the sparing methods don’t work, the only software option left is a full Hard Reset, which will delete all user data, returning the phone to factory status. Before you start, make sure you remember the password from your Mi Account and Google account, otherwise, after the reset, the device may request them to unlock.
The procedure is done in the same Recovery menu. Select the language (if the menu is in Chinese, it's usually the second button on top), then go to Wipe Data. Confirm the action by selecting Wipe All Data. The system will alert you to data loss - agree. The process can take a few minutes.
⚠️ Warning: Once reset, the phone may require a Wi-Fi connection and a password from an account that was previously synced, an Action Lock protection that cannot be circumvented by a simple reset.
If the phone goes back into reboot after reset, it's an alarm, and it's probably deeper than that, because it's damaged the firmware partition or the hardware part, and you'll need to flash the device through the computer using the Mi Flash Tool.
What to do if the menu is in Chinese?
Fastboot and Mi Flash flash flash flashing
If the software failure is critical, only a complete firmware reflash will help, USB-cable and downloaded official firmware for your model in the format of Fastboot (extension.tgz.
Put your phone in Fastboot mode. When you turn off your phone, press the Volume Down and Power buttons at the same time. You should see a hare repairing an android or the words FASTBOOT. Connect the device to your computer.
adb devices
fastboot devicesThese commands in the command line will help to check if your computer sees your device. Next, run the Mi Flash Tool, select the folder with the unpacked firmware and press the Flash button. It is important to choose the clean all mode to completely clear the memory before writing new data.
💡
Use the original. USB-cable and connect the phone directly to the motherboard port (behind the system unit), bypassing USB-This will provide stable voltage and data transmission during firmware.
Hardware problems and memory wear
It's not always the software's fault. If Xiaomi keeps rebooting after all the manipulations, it may have failed the eMMC or UFS memory chip. This is a common problem for budget and mid-range models after 2-3 years of active use. The memory is crumbled, and the phone can't physically read the launch files.
It's also worth checking the power button. If it's stuck or has poor contact, the phone may perceive it as a reboot signal. Try tapping the body gently or pressing the button several times -- if the nature of the reboot changes, it's about the mechanics.
In some cases, the problem lies in the bloated battery, which can press on the plumes or board, causing a short circuit, visual inspection of the back cover (if it is removable) or the case for bloating is mandatory.
💡
If the phone is rebooted even in Recovery or Fastboot mode, the probability of hardware failure (memory, processor, board) is more than 80%.
Preventing problems during updating
To avoid a situation where the phone turns into a brick, follow simple rules: always charge the device to a minimum of 60-70% before installing updates. Unstable voltage is the main enemy of the recording process.
Don't install updates immediately after they're released. Wait 1-2 weeks and read other users' feedback on the forums. If there are critical bugs in the new version of MIUI, it will quickly become known. Also regularly back up important data to the Mi Cloud cloud or to your computer.
- 📱 Check the vacant space: you need a minimum for updating 5-10 GB of free memory.
- 📶 Use stable Wi-Fi, not mobile internet, to download the service pack.
- 🔒 Unlock the bootloader officially if you plan to experiment with firmware.
- 🛡️ Do not disable antivirus and system protection during the installation of updates.
