Modern Xiaomi, Redmi and Poco smartphones are famous for their functionality, but even they sometimes encounter software glitches. Hang-ups, endless reboots, or upgrade issues are situations where the user needs to know how to reflash the device. Recovery mode is a hidden part of the system that allows you to perform critical operations such as data reset or reinstall the operating system, even if the main Android interface is not booting.
Before you start any manipulation of system files, it is important to understand the risks: improper actions can lead to loss of warranty or turn the device into a brick. However, if you follow proven algorithms and use original files, the recovery process is successful. In this article, we will discuss in detail all the stages of preparing and performing the firmware reflash through the built-in recovery mechanism.
There are two main ways to solve problems: simply resetting user data or completely reinstalling software. The choice of method depends on the degree of damage to the system. If the phone turns on but is unstable, often cleaning the cache helps. In more complex cases, when the system does not boot at all, a complete reinstallation of firmware via Recovery mode is required.
Preparing a smartphone for flashing
The first and most important step is to prepare the device, and make sure that the battery level is at least equal to the level of the battery. 60-70%. Interrupting the firmware process due to battery discharge is the surest way to damage the software part of the smartphone without the possibility of recovery by software methods. SD and SIM-map to avoid accidental damage to data on them.
The second step is backup. Recovery flashing almost always means deleting user data completely. Contacts, photos, instant messengers and files will be permanently lost if you don't backup in advance. Use Mi Cloud or Google Drive cloud services, or copy important files to your computer.
☑️ Checklist before firmware
The third aspect of the preparation is to determine the exact model of the device. The firmware from Redmi Note 10 will not work for the Redmi Note 10 Pro, despite the appearance of the similarity. You can find out the exact name of the model in the settings (if the phone turns on) or on the sticker under the case. Using an inappropriate file can lead to driver incompatibility and inoperability of communication modules.

Before starting the procedure, take a picture of the screen with information about the MIUI and Android version to find the same version of the firmware for recovery if necessary.
Enter Recovery Mode on Xiaomi
Access to the hidden recovery menu is a combination of physical buttons, as the touch screen in this mode often does not work or is limited. For most modern Xiaomi models, the algorithm is the same: completely turn off the smartphone and wait for the vibration or extinction of the screen. Then simultaneously press the volume button and the power button.
Hold both buttons until the Mi logo appears. Once the logo is visible, the power button can be released while holding the volume button. In a few seconds, the main Recovery Mode menu will appear on the screen. Navigation through items is done with volume buttons (up/down), and action selection with a short press of the power button.
⚠️ Warning: If you're in Fastboot mode instead of Recovery, you've pressed the volume button instead of zooming in. Just restart the device with the power button for about 10 seconds, and try again.
Recovery's interface is usually represented by a list of English-language commands. Don't be afraid of the lack of Russian at this stage, this is the standard behavior of the factory recovery. The basic features, such as Wipe Data and Reboot, are arranged in an understandable sequence. If the phone responds to touch, you can use the screen, but the buttons are more reliable.
Data reset and cache cleanup
Often, you don't need to completely flash the software bugs, you just need to reset the user settings. From the Recovery menu, select Wipe Data. Inside this section, you'll get two options: Wipe All Data and Wipe Cache. The first option deletes all files, the second option only temporary system files, saving personal data.
If you've chosen a full reset, the system will request a confirmation, a countdown timer or a button-to-click request will appear on the screen, and the partition formatting process will begin after the confirmation. user_data. The progress indicator will show the status of the implementation. Upon completion, the message "Data wiped successfully" will appear".
Cache cleaning is a safer procedure that can be done preventively. It removes temporary update files and system logs that may have been corrupted. This often helps if after a MIUI update, the phone starts to run slower or consume more power. Once the cache is cleaned, the phone doesn't reset to factory settings, your photos and apps stay in place.
| Action. | Data retention | Implementation time | Risk of data loss |
|---|---|---|---|
| Wipe Cache | Yes. | 10-30 seconds. | No. |
| Wipe All Data | No. | 1-3 minutes | High-pitched |
| Connect with MIAssistant | Depends on the action. | 5-10 minutes | Medium. |
| Reboot | Yes. | 1-2 minutes | No. |
💡
Wipe Data solves 80% of software problems associated with cyclical reboots and errors after a system update.
Installation of firmware through Recovery (Local Update)
To reinstall the system without using a computer, there is a Connect with MIAssistant mode in the Recovery menu. However, a more common method for users is to install a zip firmware archive manually. The firmware file must have a.zip extension and be loaded into the root of the phone’s internal memory (not on the phone’s internal memory). SD-Important: This method only works if you can get into the Recovery menu and the phone sees the file.
Some versions of Recovery, especially in China, have a file selection button (often a folder icon or three dots in the corner) and by clicking on it, you can point the way to the downloaded archive. If you don't, you'll need MIAssistant mode, which will switch the phone to a state that is understandable for the Mi Flash Tool program on a PC, but that's a different scenario.
If you use a standard menu, select Install (if available) or go to update mode. The system will check the integrity of the file. If the firmware file is damaged or does not match the model, a Can't verify update error will appear.
⚠️ Note: The firmware file for installation via Recovery must be in the format ZIP It's designed specifically for the Recovery method, not the Fastboot. Fastboot firmware has the.tgz extension and is not suitable for installation via the phone menu.
The installation process can take anywhere from 5 to 15 minutes, which will show the log of the operations being performed on the screen, do not try to interrupt the process or restart the device, after successful installation, the phone will suggest restarting. The first start after firmware usually lasts longer than usual - this is normal, since the system optimizes applications.
What to do if the installation is interrupted?
Common mistakes and ways to solve them
One of the most common problems is the message System has been updated or signature verification error, which means that you are trying to install an older version of the firmware on top of a new one (downgrade) or the file is modified. Official Recovery blocks such actions for security reasons, the solution is to find the current version or unlock the bootloader (which requires a data reset).
Another common error is the Unknown update package, which occurs when a firmware file is renamed, corrupted during download, or intended for another model. Always check the checksum and name of the file. For example, the firmware for the global version (Global) will not stand on Chinese (China) without first unlocking and changing the region.
Users also often experience a phone that goes into an endless bootloop after the firmware is installed, and if the data reset doesn’t work, system partitions may have been damaged, in which case the only way out is to use the computer and Fastboot mode to deep-flash all partitions of memory.
- 🔴 Error 1: “Can’t verify update” – file is not fit or corrupted.
- 🔴 Error 2: “No command” – a failure when downloading the Recovery menu, requires rechecking the buttons.
- 🔴 Error 3: Infinite Mi logo – damage to the system partition, need a reset or PC.
If your smartphone says it's dangerous, you better stop and double-check. Recovery from a failed firmware is often more difficult than the installation procedure itself. Always have a computer with ADB and Fastboot drivers installed in case of an emergency.
Completion of the process and initial setup
Once you have successfully installed the firmware and rebooted, you will see a welcome screen, the interface language must now match the one you chose to set up, the first step is connecting to a Wi-Fi network, which is necessary to activate the device and check for more recent security updates that may have come out after you created your firmware.
Then the system will suggest that you restore the data from the backup, and if you used Mi Cloud or Google Account, the process will go automatically, apps, contacts, notes, and even the placement of icons on the desktop will return to their places, which greatly accelerates the return to normal use of the smartphone.
Once you have completed the setup, it is recommended to check the main modules: camera, speakers, microphone and fingerprint sensor. Make sure that the firmware version in the settings (About phone) matches the one you installed. Also check IMEI by typing *#06# in the dialer-e to make sure that the modem works correctly.
💡
After flashing, be sure to give the phone 15-20 minutes alone for background database optimization and file indexing, otherwise the battery may run out faster than usual.
