Owners of Xiaomi, Redmi and POCO smartphones periodically face an unpleasant situation when the device refuses to update, giving a message can't verify update. This error occurs in the system application "Update" and signals that the bootloader can not confirm the integrity or authenticity of the downloaded firmware package. Most often the problem lies in the incompatibility of versions, file corruption or trying to install global firmware on top of Chinese without unlocking.
The Can't Verify update doesn't always mean that the device is fatally broken, but in most cases it's a MIUI or HyperOS security mechanism that prevents the installation of modified or incorrect software, and understanding the nature of this limitation allows you to choose the right method of bypassing the lock and successfully complete the upgrade.
There are several proven ways to solve the problem, from simply changing the region to completely flashing through the computer, and it is important to act consistently, since the wrong actions can lead to data loss or, in rare cases, the need to restore through the service center.
Causes of an error in checking the update
The main reason for the can't verify update message is to verify the digital signature of the file. Xiaomi's security system checks the hash amount of the downloaded package against the server database. If the signatures don't match or the file has been changed (for example, by enthusiasts), the process is interrupted. This is the standard procedure for protecting against the introduction of malicious code.
Often users try to manually install a newer version of Android or MIUI that is not yet available in their region. For example, trying to put Chinese firmware on a global version of a device without the appropriate bootloader access rights is guaranteed to lead to this error.
Also, consider the integrity of the file itself, if the download is interrupted or the file is corrupted during the transfer, the checksum will not converge. In such cases, the verified update failed is the normal system reaction to a broken archive.
⚠️ Warning: Attempts to repeatedly install unsigned packages may result in a Mi Account being blocked or a temporary ban on downloading updates from the company’s servers.
Preparation for manual firmware installation
Before you go to radical measures, you need to properly prepare the device and update file. First, determine the exact model of your smartphone. This information can be found in the Settings → About the phone menu. You will need the exact model name, for example, Redmi Note 12 Pro or Xiaomi 13T.
Download firmware only from trusted sources. The official miui.com site or specialized forums like 4PDA and XDA Developers are the best places to search. Make sure the firmware version is newer than the one installed now. Downgrade is usually impossible without a complete data cleanup and unlocked bootloader.
☑️ Pre-installing check
The file should be placed in the root of internal memory or on a memory card (if there is a slot). Don't hide the archive in deep folders, the system may not see it. Once the file is moved, restart the device so that the media scanner indexes the new data.
Method of activating additional update functions
The easiest way to get around this is to activate the hidden developer menu inside the Update app, which allows you to ignore some region and version checks. Open the firmware file, select "Select file" and specify the downloaded archive. If an error occurs, follow these steps.
Click the logo of the MIUI version 10 times in a row, and then there'll be three dots in the top right corner. Click on them and select "Settings." In the menu that opens, you'll need to activate the ticks:
- ✅ Turn off version check MIUI
- ✅ Disable the update check
- ✅ Disable signature verification
Once you have enabled these options, go back and select the firmware file again. Now the system must start the installation process by skipping standard checks. If the Update button remains inactive, try clearing the Update app cache through the application settings.
💡
If the error persists after activating the hidden settings, try changing the region in the phone settings to India or Nepal, then repeat the file selection procedure.
Using Recovery Mode for Installation
If the standard method didn't work, you can try installing the update via the Recovery Mode menu, which is more reliable because it works at a lower level of the system. To enter Recovery mode, turn off the smartphone completely. Then press the Volume Up and Power buttons simultaneously.
Hold the buttons until the Mi logo appears. When the menus appear in English and Chinese, use the volume buttons for navigation and the power button for confirmation. Select English, then go to the Wipe Data menu. Importantly, this step will delete all data from the device, so make a backup in advance.
After cleaning the data, choose Connect with MiAssistant (if any) or just Install if the menu allows you to select a file from memory. However, most often in stock Recovery you can not select a file manually without connecting to a PC, in which case this method boils down to resetting and waiting for the official OTA to arrive.
⚠️ Warning: Entering Recovery mode and running Wipe Data will result in the complete removal of all photos, contacts and apps.
There is also the option of installing via ADB Sideload, but this requires a computer and drivers installed.The command looks like an adb sideload name file.zip. This method often bypasses signature checks unless the archive has critical changes to the bootloader.
Comparison of Xiaomi Upgrade Methods
There are pros and cons to installing different types of devices, and the choice of method depends on your goal: simply upgrade, change the firmware region, or restore a non-working phone. Below is a comparative table of basic methods.
| Method | Difficulty | Risk of data loss | Overview |
|---|---|---|---|
| OTA (via menu) | Low. | No. | Impossible. |
| Manual file selection | Medium | No. | Partial (with hack menu) |
| Fastboot (Mi Flash) | Tall. | Yeah (full clean-up) | Only with an unlocked BL |
| Recovery Mode | Medium | Yeah (on reset) | Depends on the Recovery version |
As you can see from the table, manually selecting a file with hidden settings activation is enough to easily install a newer version. Changing a region (for example, from China to Global) requires unlocking the bootloader, which is a complex procedure.
Problems with changing the firmware region
A common cause of the can't verify update error is an attempt at cross-regional updates. If you have a global firmware phone, you can't just put a Chinese version, and vice versa.
To change the firmware type (Cross-flash), you need to officially unlock the bootloader through the Mi Unlock site. Once you get Unlocked status in Fastboot, you can use the Mi Flash Tool program on your computer. In this mode, signature verification can be disabled by the Clean all option, but this will completely delete the data.
What is Anti-Rollback and why is it dangerous?
Using third-party utilities to unlock or firmware carries risks. Untested tools may contain malicious code or misuse new Snapdragon and MediaTek processor models.
Frequent Questions and Answers (FAQ)

💡
The main rule is never to interrupt the firmware process or turn off the phone until the progress band reaches 100% and the device restarts on its own.
