When the MIUI or HyperOS operating system is upgraded in the middle, the screen goes out, the device doesn’t respond to touch, or the Xiaomi logo spins endlessly, creating the illusion of a “brick,” owners immediately imagine the worst scenario: loss of all data, the inability to turn on the gadget and expensive repairs in the service center.
But statistics show that in the vast majority of cases, the smartphone system is intact and the failure is software-based, which can be due to an interrupted Internet connection, a lack of space in the memory partition or a conflict of system files, the main thing at this point is to keep your composure and not to commit rash actions that can really harm the device.
In this article, we’ll look at all possible freeze scenarios, from a suspended boot to an endless logo. You’ll learn how to safely restart your device, how to use Recovery mode, and when to use your computer to flash. Understanding the boot structure of Android will help you quickly bring your phone back to life without losing photos and contacts.
Primary diagnostics of the device condition
Before we go to radical resuscitation methods, we need to determine exactly at what stage the failure occurred. The behavior of the smartphone when getting stuck during the loading stage of the logo is different from the situation when the screen simply went out during the download of the file. If the device warms, vibrates or periodically gives signs of life, the chances of successful recovery without loss of data are maximum.
Often users confuse “hard freeze” with a long process of optimization of applications. After a major update of the system core, the smartphone can stand idle with the logo for up to 10-15 minutes, collecting cache and checking the integrity of files.
⚠️ Warning: If the charge indicator is on red or flashing, don't try to perform complex manipulations. First, connect the original power supply and cable, let the battery at least dial 15-20% energy, as the firmware is an energy-intensive process.
For an accurate diagnosis, use the following table of symptoms and probable causes:
| Symptoms. | Probable cause | Level of risk |
|---|---|---|
| Black screen, no reaction. | Battery discharge or display failure | Low. |
| The Endless Mi Logo | Error of system files or cache | Medium. |
| Hanging on percentages (0-99%) | Interrupting data recording on flash memory | High-pitched |
| Cyclical reboot | Application conflict or damage to the bootloader | Medium. |
Once you've identified your case, you can choose the right strategy. Don't ignore the heating of the case: if the phone gets hot, let it cool before further attempts to turn on, as overheating the processor can cause false failures in the power controller.
Forced reset method
The easiest and safest way to get out of the freeze is to perform a hard reset with a combination of buttons, which doesn't delete your personal data, it just forcibly breaks the loop of the freeze and initiates a normal operating system boot, which solves the problem in 80% of cases.
To perform the procedure, you need to press the power button. Most modern Xiaomi, Redmi and POCO models need to hold the power button for about 10-15 seconds. If the device does not respond, try the combination: the power button plus the volume button. Hold them until the screen goes out and the vibration or brand logo appears.
☑️ Checking before rebooting
Sometimes the system may require input. PIN-It's a standard Android security measure that protects data when you're not updating, and if you're restarting your phone, don't interrupt the process and make sure your Wi-Fi network is stable.
💡
If the power button is physically damaged or stalls, try connecting the phone to your computer via a computer. USB-cable – in some cases, it can trigger a withdrawal from deep sleep.
Using Recovery Mode for Resetting
If a simple reboot doesn't work, and the phone continues to go on an endless loop or hang on the logo, you need to use the Recovery system partition. This is a special mode built into the device's memory that allows you to manage the boot regardless of the main system, here you can clear temporary files that may have been damaged during the update.
To enter the Recovery menu on a device that is off, press both the power button and the volume button. Hold them until the Mi-Recovery menu appears. Navigation is done with volume buttons (up/down), and the power button selects the item. You need to find Wipe Data or Wipe Cache.
⚠️ Warning: Selecting the Wipe All Data option will result in the complete removal of all photos, contacts and apps.Use the Wipe Cache option (if available in your version of Recovery) to save data but clear temporary update files.
Modern versions of MIUI often have two-item menus: Reboot and Wipe Data. If you choose Wipe Data, the system will ask you to confirm the action by entering the word "yes" or selecting "Confirm." Once cleaned, select Reboot -> Reboot to System. The first run can take up to 5-7 minutes.
It is important to understand the difference between cache and user data. Update cache is a temporary installation file that is no longer needed after installation. Deletion is safe. However, if critical configuration files are damaged, a complete reset may be required, as the system will alert you.
Recovery through Fastboot mode
Fastboot mode is a low-level debugging protocol that allows you to interact with your phone directly, bypassing the operating system. If the phone is stuck in the upgrade phase and does not boot, connecting to your PC in Fastboot mode is often the only way to “revive” the device without going to the service.
To put Xiaomi smartphone in Fastboot mode, turn it off and press the power button and the volume down button at the same time. The screen will show an image of a hare repairing an android, and the inscription FASTBOOT. Connect your phone to your computer through high-quality USB-You need to install drivers on your PC. ADB/Fastboot and the Mi Flash Tool utility or use the command line.
The connection check is done via the Windows command line. Enter the command:
fastboot devicesIf you see the serial number of the device in response, the connection is successful. If the line is empty, check the drivers in Device Manager or try another one. USB-port (preferably) USB Fastboot can run a fastboot reboot command for a normal reboot or fastboot oem edl to go into disaster recovery mode (requires an authorized account).
What is EDL mode?
Using Fastboot is safe for hardware, but requires careful firmware selection. An incorrectly selected version of software (such as firmware for the Chinese global version) can lead to a bootloader lock or loss of communication functions. Always check the region of the device before you run the firmware.
Manual installation of firmware through Recovery
If an automatic air update (OTA) has caused a freeze, the best solution is to manually install the current firmware version, which bypasses the errors of the OTA bootloader and re-write system files, and you will need to download the full firmware archive (.zip format for Recovery) from the official website or proven resources.
Copy the firmware file to the root of the phone’s internal memory (if it’s defined as a drive) or to the root of the phone’s internal memory. SD-Then enter Recovery mode (as described above). Select the language (usually available in English and Chinese), then click Install or Connect with MIAssistant (depending on the menu version). Find the downloaded archive and confirm the installation.
- 📂 Make sure the firmware file has a.zip extension and is specifically for Recovery, not Fastboot.
- 💾 Do not interrupt the installation process: even if the progress bar is in place for a few minutes, it is normal to write large amounts of data.
- 🔋 The battery must be at least 50% charged, otherwise the installation may be interrupted at a critical stage.
Once you've installed it, you'll want to restart, and the first run after manual flashing always lasts longer than usual, because you're re-creating your system libraries, and if the phone turns on and shows you the desktop, congratulations, you've successfully restored the operating system.
💡
Manually installing firmware through Recovery is the most reliable way to fix OTA errors, as it overwrites all system partitions clean.
Common Errors and How to Resolve Them
Users often face repetitive problems during the recovery process, and understanding the nature of these errors helps to avoid wasting time, such as a “Can’t verify update” error that means that the firmware file signature is not the same as the current version of the bootloader or the firmware region is different from the device region.
Another common problem is “Not enough space,” which means that the Data partition is crowded and the system has nowhere to unpack temporary update files, in which case only cleaning the data through Wipe Data in Recovery mode will help, which, alas, will lead to file loss if they were not saved to the cloud.
Also worth mentioning is the network check error: If a phone writes "Network error" when trying to download an update in Recovery, check your DNS settings or try to distribute the Internet from another phone. Sometimes Xiaomi servers may not be available and you have to wait several hours.
⚠️ Warning: Never attempt to interrupt the firmware writing process by removing the battery (if it is not removable) or disabling the cable.This is guaranteed to damage the boot sector and require complex repairs to the service using programmers.
If none of the software methods worked, and the phone still fails to respond or produces specific error codes, the problem may lie in the hardware, the failure of the flash memory or power controller is often disguised as a software failure, in which case further independent actions are useless.
