How to Update Android to Xiaomi: A Complete Firmware Guide

Xiaomi’s ecosystem is famous for its flexibility, but it’s the constant updates to MIUI that often raise the most questions. Device owners regularly look for ways to get fresh Android to improve performance, add new features and close security vulnerabilities. However, this process does not always go smoothly, especially when transitioning between major versions of the operating system.

Before you take action, you need to understand the risks. Any interference with the software code of the device is potentially dangerous if you interrupt the power or choose the wrong file. In this article, we will discuss in detail how to update Xiaomi to the latest version of Android using official and proven methods. We will look at the nuances of working with MIUI 12, 13, 14 and the latest HyperOS.

Not all models receive updates at the same time, but the company’s policy is to roll out in stages, so your device may notify you later than a friend’s smartphone. Sometimes the wait is delayed, and then you have to take the situation into your own hands, using manual methods of installing software through the Internet_recovery_ orthologies.

Preparation of the device for the update procedure

Any major operation requires prior preparation, and ignoring this phase can lead to loss of personal data or the smartphone becoming a brick. The first step is to create a full backup, which can be done through the Mi Cloud, Google Drive or locally on the memory card and computer. Save contacts, photos, correspondence and application settings.

The second critical point is battery power. The firmware process can take anywhere from 15 minutes to an hour, and the phone should not shut down. Make sure the charge level is at least 60%, preferably 100%. Also check for free space in internal memory. Service packs often require 5 to 10 GB of free space to download and unpack.

⚠️ Note: If you use an unlocked bootloader, the procedure may be different, and in some cases, upgrading from global firmware to Chinese (or vice versa) requires a complete data reset (Wipe Data).

Be sure to check the stability of your Internet connection if you plan to download files through the air. For heavy upgrades, you should use Wi-Fi to keep your mobile traffic limit in check, and remove third-party antivirus and memory cleaners that may conflict with system processes during installation.

Official method: Update through Settings (OTA)

The easiest and safest way to get a new version of Android is an OTA (Over-The-Air) update. The system itself checks for new packages and suggests installing them. Go to Settings → About Phone and click on the MIUI version logo. If the update is available, a download button will appear.

However, it is often the case that the phone says "No Updates found" even though your model has already released a new Android, this may be due to regional restrictions or phased distribution, in which case you can try to change the region in the settings (Settings → Additional settings → Region) to "India" or "Singapore", check the updates, and then return your region, which sometimes causes the server to issue a packet.

If automatic search didn't work, you can use the built-in file selection function. In the update menu, click three dots in the corner of the screen and select "Select firmware file." Here the system will suggest downloading the current package or selecting the previously downloaded one. This method is good because it checks the integrity of the file before installing.

💡

If OTA-update hangs during the check or download phase, try clearing the "Software Update" app cache through the app menu or switching to mobile Internet if Wi-Fi is unstable.

It is important to understand that OTA-The method updates the system without losing data only if you go within the same branch (for example, from Global to Global".

Manual installation via Recovery Mode

When the air method doesn’t work, manually installing Recovery firmware comes to the rescue, a method that requires you to download the correct archive from an official website or verified sources like miuiroms.com. You need a file with the.zip extension that matches your model and firmware type (Recovery ROM, not Fastboot!).

Once you download the file, put it in the root of the smartphone's internal memory. Then go back to the update menu, click three dots and select "Select firmware file." Find the downloaded archive. If the file fits, the phone will suggest restarting and starting installation. This process takes longer than OTA, and the phone will be rebooted several times.

There is also a “clean” installation method through Recovery that helps to get rid of errors and bugs of the previous version, and to do this, after selecting a firmware file in the update menu, you need to click not on the update button, but several times tap on the MIUI logo (or use the hidden menu, if available) to activate the “Wipe Data” mode.

⚠️ Note: When you select the "Wipe Data" option, all your files, photos and apps will be permanently deleted!

Use of Mi Flash Tool and Fastboot

For those who want to completely reflash the device, change region (for example, from CN to Global) or restore the brick, there is a utility Mi Flash Tool. This method works only in Fastboot mode and requires an unlocked bootloader.

First, unlock the bootloader through the official Mi Unlock utility on the PC. This will bind the Mi Account to the device and require a wait of 7 to 168 hours. After unlocking, download the Fastboot firmware (archive.tgz), unpack it and open the Mi Flash Tool. Connect the phone in Fastboot mode (clicking the volume button when you connect the cable) and press "Flash".

The Mi Flash Tool has three firmware modes: Save user data, Clear all, and Clear all and lock, which is available only when you are firmware in the same region as before. If you are changing region (CN -> Global), use only Clear all.

💡

Fastboot mode is the only way to change the region of the device (for example, from Chinese to Global) or restore the phone if it stopped booting into the system.

Don't turn off the USB cable during the process. If the progress indicator is up or red text appears in the logs, it's possible that the drivers are installed incorrectly or the cable is damaged. Use the original cable and USB 2.0/3.0 port on the motherboard (not through the hubs).

Solving Common Errors When Updating

Even if you follow all the instructions, you can get errors. UI not responding or bootloop after the update, in which case you should first try to enter Recovery mode. + Vol Up) and make Wipe Cache / Wipe Data. This solves 90% of the problems with cyclic reboot.

If your phone doesn't see the firmware file or writes "Baget is corrupted," check the integrity of the archive. It may not have been downloaded completely. Try downloading it again, preferably from another source or browser. Also make sure that the file is in the root folder of internal memory, not in the Download folder.

• 🔴 Error 10: Server connection problem Solution: Change network (Wi-Fi to mobile Internet) or DNS-server.
• 🔴 Error 4: The file is not suitable for this model. Solution: you downloaded the firmware for another device or incorrect region (Global instead of the "Global" model). RU).
• 🔴 Error 7: Not enough space. Solution: free up 10 GB or use a memory card (if you support the choice of a c-size device). SD).

In case the phone went into a deep bootloop and does not respond to the buttons, only flashing through Fastboot or flashing it will help. EDL-Emergency Download Mode, which requires an authorized Mi Account and often paid service centers.
