Air firmware update (OTA, Over-The-Air is the standard way to get new features and security patches on Xiaomi smartphones, but even this simple process can raise questions about why the update doesnβt come, how to install it manually, or what to do if the device is stuck on the logo. MI In this article, we will analyze all the nuances, from checking the availability of updates to restoring the system when crashes.
It is important to understand that OTA-Updates fall into two types: incremental (replace only modified files) and complete (overwrite the entire system), the former taking up less space and installing faster, but can cause errors if the previous firmware has been modified; the latter are more reliable, but weigh 2-4 GB. We will show you how to work with both options, and we will also reveal the secrets of speeding up the process and bypassing regional restrictions.
What is it? OTA-Firmware and why you need it
OTA (Over-The-Air) is a wireless software update technology that allows you to install new firmware versions without connecting to a computer. For Xiaomi, it is the main way to distribute MIUI, HyperOS and security patches.
- π Automation: the device checks and downloads updates in the background.
- π‘οΈ Security: Firmware signed with Xiaomi digital certificates, which excludes file swapping.
- π± Compatibility: All models are supported β from the budget Redmi to the flagship Xiaomi 14.
- π§ Minimum risks: if the system fails, it will roll back to the previous version (on most devices).
But OTAs have drawbacks, such as regional limitations: firmware for global (MI) and Chinese (CN) versions of devices comes out at different times, and incremental updates can conflict with root rights or custom recoveries, leading to a device "brick" (inoperability) and we'll explain later how to avoid this.
β οΈ Note: If your smartphone is unlocked via Fastboot or has a Recovery installed TWRP, OTA-updates may cause data loss, in which case it is recommended to use full firmware via the Mi Flash Tool.
How to check availability OTA-update
Before installing the update, make sure it is actually available for your model.
- Open Settings β About the phone β System update.
- Click on the three dots in the top right corner and select Update Checker.
- If there is an update, the system will show its size, version number and list of changes.
If the update does not come, the reasons may be as follows:
- π Regional restrictions: Your model is waiting for firmware for another market (e.g, EEA Global instead).
- π΅ Server problems: Xiaomi sometimes suspends the distribution of updates due to bugs.
- π Low battery charge: system blocks installation if charge is less than 30%.
- πΆ Unstable Internet connection: Update may not load via mobile network.
| Problem. | Decision |
|---|---|
| Update not in progress | Check the firmware region in Settings β Additional β Region. Change to India if necessary (updates come out earlier). |
| "Failure to download" error | Connect to another Wi-Fi network or use a VPN (e.g. Singapore). |
| The device is not supported | Install firmware manually via Recovery or Fastboot. |
| Lack of memory | Clear the cache in Settings β Storage β Clear the cache or transfer the files to the memory card. |
Preparing the smartphone for update
To avoid problems during the OTA installation, follow the following steps:
Make a backup copy of the data|Charge the battery to 50% or higher|Connect to a stable Wi-Fi network|Close background annexes|Check the vacant space (minimum 3 GB)-->
Backup is a critical step. MIUI HyperOS data reset. Use the built-in Settings function β Additional β Backup or third-party tools like Swift Backup (requires a root).
If you have Magisk, Xposed or other modifications installed on your device, you need to temporarily turn them off.
1. Open the Magisk app.
2. Press "Uninstall" β "Complete Uninstall."
3. Reset the device.β οΈ Note: On devices with an unlocked bootloader (bootloader) OTA-updates can result in loss of root rights or even a soft breech ( looped download.
Installation of OTA-updates: step-by-step instructions
If an update is available, you can install it in two ways: automatically (via the update menu) or manually (via Recovery).
Method 1: Automatic installation
This is the easiest method that suits most users:
- Go to Settings β About the phone β System update.
- Click Download and wait for the download to be completed.
- After downloading, the Install button will appear - press it.
- The device will restart and start installation (this can take 5-15 minutes).
If a Couldn't verify update error appears after the reboot, it means that the firmware file is corrupted.
- Delete the uploaded file in /data/ota_package (You'll need a rout-rights guide).
- Download the update again or install it manually.
Method 2: Manual installation via Recovery
If the automatic installation does not work, you can download the firmware yourself and install it through Recovery:
- Download the full. OTA-Firmware for your model from the official Xiaomi website (choose the version of Recovery) ROM).
- Rename the file to update.zip and place it in the root of internal memory.
- Turn off the device, then press Volume up + Power to enter Recovery.
- Select Install update.zip and confirm the installation.
What if Recovery doesnβt see the update.zip file?
Important: On HyperOS devices (such as Xiaomi 14 or Redmi Note 13), manual installation via Recovery may be blocked, in which case use Fastboot or Mi Flash Tool.
Resolving common errors when OTA-renewal
Even with the right installation, there can be failures. Consider the most common errors and their solutions:
| Mistake. | Reason. | Decision |
|---|---|---|
| Error 7 (in Recovery) | Disparity between the device model and the firmware. | Download the firmware specifically for your model (check in Settings β About phone β Model). |
| Hanging on the MI logo | Conflict with modifications (root, TWRP) or damage to system files. | Log in to Fastboot (Loudness Down + Power) and reflash the device through the Mi Flash Tool. |
| Couldn't verify update | A damaged firmware file or lack of space. | Delete the file in /data/ota_package and download again. 4+ GB memory. |
| Network error when downloading | Blocking Xiaomi servers in your area. | Use a VPN (e.g., ProtonVPN with a server in Singapore or India). |
If after the update the device stopped turning on or got stuck on the boot, try a hard reset:
- Press Volume Up + Power for 10 seconds to enter Recovery.
- Choose Wipe Data β Wipe All Data.
- After resetting, try installing the firmware again.

If so, OTA-Updates are missing root rights, they can be restored by re-squeezing Magisk through custom Recovery. Magisk.apk, rename Magisk.zip and set through TWRP or ADB Sideload
How to speed up the acquisition OTA-update
If you donβt want to wait for the update to reach your region, there are a few ways to speed up the process:
- π Change of the firmware region: in Settings β Additionally. β Select India (updates are coming sooner).
- π Manual download: download firmware from official sources (for example, Xiaomi Firmware Updater).
- π‘ VPN: Connect to servers in Singapore or Hong Kong, where updates are spreading faster.
- π± Participation in Beta Testing: Register for the Program MIUI Beta via official website.
For Redmi and POCO models, update trackers can be used, such as:
- Telegram channel MIUI Updates Tracker
- XiaomiUI website
β οΈ Note: Install firmware from another region (e.g, CN on the global device) may result in loss of function (NFC, Google Pay) or unstable work. Always check compatibility!
OTA on locked and unlocked devices
If your smartphone is unlocked (unlocked bootloader), OTA-updates may not work properly. Here's what you need to know:
- β Blocked bootloader: Updates are installed without problems, but you wonβt be able to roll back to the previous version.
- β οΈ Unlocked loader: OTA This can lead to a blink if the firmware checks the integrity of the system partition.
- π Devices with TWRP: beforehand OTA You need to return the stock Recovery, otherwise the update will not get up.
For HyperOS devices (e.g. Xiaomi 13T, Redmi K70), the process is different:
- Download the full firmware (not incremental!) from the official website.
- Unpack. ZIP-archive and find the file flash_all.bat (for Windows or flash_all.sh (for Linux/Mac).
- Connect the device in Fastboot mode and start the script.

On HyperOS devices, manual firmware via Fastboot is the only reliable way to upgrade when the bootloader is unlocked.
