Owners of Xiaomi, Redmi and POCO smartphones often face a situation where the device suddenly restarts and a message appears on the screen that the update is being verified.This process can take from a few seconds to several minutes, but sometimes the phone “hangs” at this stage, causing panic in the user. Understanding what is happening at this point inside the operating system will help to maintain calm and correctly assess the risks.
In essence, verification is about verifying the integrity and authenticity of system files before installing them or immediately after a successful update. The MIUI or HyperOS security mechanism checks digital signatures with the manufacturer's servers to make sure that the firmware has not been corrupted or altered by unauthorized software. If you see this screen, then the system is trying to make sure the data is correct.
In most cases, this stage is normal and invisible to the owner, but failures in the communication module, interruption of download or interference with system files can lead to a cyclical reboot. Next, we will discuss in detail why this situation arises, how to distinguish normal operation from a critical error and what actions should be taken to bring the gadget back to life without losing data.
What is the verification process and why is it needed
The verification process is a critical security element of today’s mobile operating systems. When your device reports a validation, it performs a complex procedure to compare the hash sum of system partitions to reference values, to prevent malicious code or corrupted files from being installed that could bring your smartphone down.
This function is especially relevant for devices with an unlocked bootloader or those on which custom customized devices were previously installed_recovery_. Android Verified Boot system (AVB) The trust chain checks: the bootloader checks the kernel, the kernel checks the system, and the system checks the user data. If at least one link in the chain is in doubt, the process can be stopped or started in safe mode.
💡
If the verification is successful but the update is not installed, try clearing the Recovery partition cache before trying to download again.
It is worth noting that long-term verification is often observed after a forced reboot during the background load of updates. At this point, the system partition may be in a state of inconsistency, and the OS takes time to check all memory sectors.
Why Xiaomi is hanging out at the verification stage
When a smartphone is endlessly rotating its logo or on a verification screen, it usually indicates a conflict of software components. One of the most common reasons is a lack of free space in internal memory. To properly work the mechanisms for checking and unpacking updates, the system requires a reserve of at least 10-15% of the total storage.
Another risk factor is an unstable Internet connection at the time of downloading the service pack. If the firmware file was downloaded with errors or not to the end, the built-in security mechanism will block the installation and start a cycle of checks trying to find the whole data, and problems can arise due to the use of modified versions of applications or Superuser (Root) rights that make changes to the system files.
- 📉 Lack of free memory for temporary system files.
- 📡 Interrupt Wi-Fi or mobile data connection during download.
- 🔋 Battery discharge below 20% at critical installation time.
- 🛠 Root or modified bootloader (Custom Recovery).
Particular attention should be paid to cases where the problem lies in the hardware: the degradation of flash memory or overheating of the processor can lead to errors in reading data, which the system perceives as a violation of integrity, in which cases software methods may not help, and diagnostics will be required in the service center.
Major Verification Errors and Their Codes
When an update is problematic, the system often outputs specific error codes or text messages that help diagnose the cause of the crash, and understanding these signals allows users to choose the correct recovery strategy, and users often encounter an error that indicates a problem with digital signatures.
If a message appears on the screen that the current version is newer than the installed one, it means an attempt to roll back on the older firmware.The security policy of Xiaomi, like most manufacturers, prohibits the downgrade (rollback) of the system without completely cleaning up the data to prevent security vulnerabilities that were closed in the new versions.
| Code/Message | Probable cause | Decision |
|---|---|---|
| Can't verify update | Damaged firmware file | Download again via Wi-Fi |
| Current version is newer | Attempted rollback version | Use the full version (Recovery ROM) |
| Not enough storage | Little space for memory | Clear cache and files |
| System partition corrupted | System file error | Reset to factory settings |
What is the “Zip File Signature Verification Failed” Error?
It’s important to distinguish between software failures and server errors. Sometimes the problem isn’t with your phone, but with Xiaomi servers, which can be congested on major update days, and in such cases, it’s worth waiting hours or days before resorting to drastic measures.
Step-by-step: how to fix the hanging
If your smartphone is stuck in the verification phase, don't panic right away. 90% In cases, it solves the problem without losing identity. The first step should always be waiting: give the device. 15-20 It may be slow because of fragmentation of memory.
If the wait doesn't work, try a forced reboot, press the power button and hold it for 10-15 seconds before the vibration and the logo appears, and if the phone boots, go to settings immediately and try to clear the system update application data.
☑️ Actions when getting stuck
If a simple reboot doesn’t work, try re-entering Recovery mode. Turn off your phone and press the power and volume buttons at the same time. In the menu that appears (if it supports Russian or English), select “Wipe Data” -> “Wipe Cache” (don’t confuse it with Wipe All Data if you want to save photos and contacts).
⚠️ Note: Performing a complete Wipe All Data cleanup will delete all photos, contacts and applications. Use this method only if other methods have not helped and you have a backup.
Manual Update installation via Recovery
When automatic updates (OTAs) are constantly failing, the most reliable way is to manually install the firmware, which allows you to bypass any update bootloader bugs and install a fresh, complete version of the system directly, and you will need to download the full firmware archive (Recovery ROM) for your particular model.
The firmware file has a.zip extension and usually weighs between 3 and 5 GB. After downloading, rename the file to update.zip (in some cases, this is mandatory) and place it at the root of the device's internal memory. Don't put the file in folders, it should lie separate from other files.
Path to file: /internal_storage/update.zipNext, you need to start the update process through a special menu. Go to Settings → About Phone → MIUI version and click three dots in the corner of the screen. Select "Select firmware file" and specify the downloaded archive. The system will run the check and, if the version is suitable, prompt you to restart for installation.
💡
Manual installation of the full version of firmware (Recovery ROM) solves 95% of problems with cyclic updates and verification errors, as it replaces all system files with serviceable ones.
If you can't log in through the settings, you can use Recovery Mode. Press the power and volume buttons, select the language (if available), and click "Install update.zip." The system will find the file at the root of the memory and start installing, a method that is the gold standard for Xiaomi's recovery.
Preventing errors in system updates
To avoid future verification issues, you should stick to a few simple rules for using your smartphone: First of all, always control the space available. Android requires space to maneuver, and crowded memory is the main enemy of stable operation.
It is also recommended to clean up the cache of system applications regularly.The accumulated "garbage" can conflict with new system libraries implemented during the update.Use the built-in "Security" utility for cleaning, but avoid aggressive cleaners from third-party developers who can remove important system logs.
- 🔋 Always charge your phone to at least 50% before launching an update.
- 📶 Use a stable Wi-Fi connection while avoiding public networks.
- 🚫 Do not interfere with the system in the background during installation.
- 💾 Backup important data before major Android updates.
Another important aspect is that you should not rush to install updates in the first days after they are released. Often, early versions contain bugs that are detected by the first users. Official forums and communities help you quickly get information about the presence of critical errors in a new build.
⚠️ Note: If you are using a global firmware version, never try to install a Chinese version (CN ROM) It's going to lead to a bootloop cycle and require a complicated flashing.
When you need to contact the service center
Despite the many software solutions, there are situations where the problem is deeper, and if after a complete flash and reset to factory settings, the phone continues to hover on verification or goes into an endless reboot, there is a high probability of hardware failure.
A common cause of these symptoms is a malfunction of the flash memory or power controller. During the upgrade process, there is an intensive recording and reading of data, and if the memory cells are damaged, the system cannot correctly write new files, going into protection.
If your device is warranty-free, self-opening or attempting to flash through Fastboot with the bootloader unlocked may deprive you of warranty service.In such cases, it is wiser to contact official Xiaomi partners for diagnosis.
