Modern Xiaomi, Redmi and POCO smartphones are powered by MIUI shells or the new HyperOS, which require regular updates to ensure security and stability. However, the built-in OTA (Over-The-Air) mechanism sometimes crashes, fails to see a new version or offers a latency update. In these situations, users are looking for a way to manually update Xiaomi to access fresh features right now.
Manual firmware installation is a process that requires care, but it's completely safe if you follow the algorithm. You can choose the method through the Recovery menu or a deeper method through Fastboot mode using your computer. The specific method you choose depends on your current version of the system and the desired result.
In this article, we will discuss in detail all the stages of preparing, downloading official files and the installation process itself, you will learn how regional firmware versions differ, how to avoid personal data loss, and what to do if the phone has stopped responding to standard update methods.
Preparation of the device and choice of firmware method
Before you start any manipulation of system software, you need to do thorough preparation. Data backup is the first thing to do, even if you plan to upgrade without reset. Nobody is immune to accidental errors, so save contacts, photos and important documents to the cloud or to your computer.
The firmware for Xiaomi is divided into two main types: Recovery (.zip format) and Fastboot (.tgz format). For most users who want to just upgrade without unlocking the bootloader and using a PC, Recovery is the right method.
⚠️ Warning: Make sure the battery is at least 60% powered. interruption of the firmware process due to battery discharge can lead to a software failure known as a "brick".
It's also important to check the region of your current firmware, and if you have a global version, you need to update to a global version, and if you try to install Chinese firmware (CN) on top of a global one without unlocking the bootloader, you'll end up with a compatibility check error.
Where to download the official firmware for Xiaomi
Finding a current and secure file is a critical step: using third-party resources with modified builds can lead to data leakage or unstable operation of the gadget. Official sources guarantee the integrity of digital signatures.
The most reliable resource is a dedicated portal that aggregates links from the company's servers, where files are sorted by device models and installation types, and you'll need to find the exact codename of your device, such as davinci for the Redmi K20 or euclid for the Mi 8 Lite.
When downloading, pay attention to the file size. Recovery firmware usually weighs about 2.5-3.5 GB, whereas a Fastboot image can take up 4-5 GB. If the file weighs suspiciously little (for example, 100 MB), this is not a full firmware, but only an update patch.
- 📂 Official website MIUI Download – the main source for all regions.
- 🌐 Xiaomi Firmware Updater – a convenient directory with a history of all versions.
- 📱 Mi Community – sometimes contains direct links OTA-packet.
- 💻 Mi Flash Tool – automatically downloads images for Fastboot mode.
💡
Only use files with the.zip extension to update via the phone menu.Tgz files are designed exclusively for firmware through your computer.
Method 1: Update via Recovery (without a computer)
This is the easiest and most accessible method for any user. It doesn't require a computer, USB-All actions are performed directly on the smartphone screen through the standard settings menu.
The method is to select a previously downloaded archive through a hidden menu of engineering settings, so that the firmware file (renamed update.zip) must be at the root of the device's internal memory. Do not put it in folders, otherwise the system will not see it.
The algorithm is simple: open the Phone app, dial ##777## (some models may have different code, sometimes ##6484## and go to the Update Check menu). In the window that opens, click on the three dots in the upper right corner and select Select firmware file.
☑️ Checklist before firmware through Recovery
Once the file is selected, the system will check, and if all conditions are met, the Update button will appear. The phone will restart and the installation process will begin, which can take from 5 to 15 minutes.
Method 2: Fastboot and Mi Flash Tool
Fastboot is more advanced and requires a Windows PC, which allows not only to update, but also to completely clean up memory partitions, which often helps to correct software errors that cannot be fixed by a conventional reset.
To work, you will need the Mi Flash Tool utility and installed drivers. ADB/Fastboot. Unlike the Recovery method, it uses a system image in.tgz format, which must be pre-extracted into a root folder on the disk (the path should not contain Cyrillic).
Put your smartphone into Fastboot mode, pressing both power and volume down buttons when the device is off. Connect your phone to your computer with a cable. In the Mi Flash Tool, press the Refresh button and the device should be selected in the list.
fastboot devicesThis command in the command line (if ADB is installed) will confirm the connection of the device. In the Mi Flash Tool graphical interface, it is important to choose the correct firmware mode at the bottom of the window: Clean All (complete cleaning), Save User Data (saving data) or Clean All and Lock (cleaning and locking the bootloader).
⚠️ Note: When you select Clean All and Lock mode on a device with an unlocked bootloader or change region (e.g., Global to China), the phone may lock.
What if the Mi Flash Tool can't see the phone?
Table of differences in update methods
To make it easier for you to decide on the method of firmware, we have systematized the key differences in the table below, which will help you avoid errors and choose the best path for your situation.
| Parameter | Recovery (ZIP) | Fastboot (TGZ) | OTA (Automatically) |
|---|---|---|---|
| Presence of PC | Not required | Definitely (Windows) | Not required |
| Data retention | Yes (default) | Depends on the choice of regime. | Yes. |
| Change of region | Limited (not available from Global on CN) | Possibly (unblocking required) | No. |
| Difficulty | Low. | Tall. | Minimum |
| Speed of installation | Average (10-15 min) | High (5-10 min) | Depends on the server. |
💡
Recovery is ideal for scheduled upgrades, and Fastboot is essential for system recovery after crashes or deep cleaning.
Typical errors and their solution
When you manually install firmware, users often encounter error messages, the most common being “Can’t verify update,” which means that the digital signature of the file doesn’t match the current version of the system or region.
If you try to roll back on an older version of Android or MIUI, the system will block the installation for security reasons. In such cases, only Fastboot mode with full data cleaning helps, but this requires an unlocked bootloader.
Another problem is the endless restart (bootloop) after installation, if the phone is stuck on the Mi logo for more than 10 minutes, you need to perform a forced reboot (press the power button for 15 seconds).
- 🚫 Error "Zip file is broken" - the file is not downloaded completely, check the checksum or download again.
- 🚫 Compatibility error – trying to install firmware from another phone model.
- 🚫 Not enough space - free up 5-6 GB of internal memory before starting.
It is important to understand that unlocking the bootloader is a prerequisite for changing the firmware region (for example, installing the Chinese version on the global device).
