How to reinstall Android on a Xiaomi smartphone: a complete guide with nuances

Reinstalling the operating system on smartphones Xiaomi may be required in a variety of situations: from banal failures and slowdowns to critical errors when the device refuses to boot. Unlike the iPhone, where the recovery process is strictly regulated, Android systems (especially on Xiaomi, Redmi or POCOdevices) offer more flexibility - but also more risks. There is no universal solution here: methods vary depending on the model, firmware version, and even the region of purchase.

It is important to understand that reinstalling Android is not just an “update through the settings.” We are talking about a complete system reset with possible data loss, unlocking the bootloader, or even installing alternative firmware. For example, owners Xiaomi 12T Pro or Redmi Note 11 are faced with different nuances: the former can use Fastboot-mode for flashing, while the latter sometimes need to bypass the lock via EDL. And this is not to mention custom recoveries like TWRP, which provide access to advanced functions, but at the same time void the warranty.

In this article we will look at all the current ways to reinstall Android on Xiaomi —from official methods via Mi Flash Tool to manual firmware via ADB and recovery via Recovery. We will pay special attention to preparation (data backup, bootloader unlocking) and typical errors that turn a smartphone into a brick. If you have never done firmware, start with the official instructions. If you are an experienced user, look for sections about custom ROMs and EDL-mode.

Preparing for reinstallation: what you need to do before you start

The first and most important step is saving data. Reinstalling Android on Xiaomi in 90% of cases leads to complete formatting of the internal memory. Even if you plan to use the non-reset method (OTA-refresh), there is always a risk of failure. Therefore:

• 📱 Synchronize contacts, photos and documents s Google Account or Mi Cloud. Check that the backups have been created: go to Settings → Accounts → Mi Cloud → Backup.
• 💾 Copy files to a PC or external drive. Use MTP-mode (connecting as a media device) or Xiaomi File Manager for selective copying.
• 🔑 Save passwords and application data. For this, suitable Google Password Manager or specialized utilities like Titanium Backup (requires root).
• 📋 Write down the IMEI and serial number. They will be needed if the network disappears after the firmware. Find them in Settings → About phone or under the battery (for models with a removable battery).

The second critical point is unlocking the bootloader (Bootloader). Without this, most users Xiaomi only installation of official firmware via Recoverywill be available. To unlock the bootloader:

1. Link the device to Mi Account to Settings → Advanced → Developer → Mi Unlock status.
2. Download Mi Unlock Tool from Xiaomi official website (registration required).
3. Connect your phone in mode Fastboot (press Volume down + Power with the device turned off) and follow the instructions of the app.

⚠️ Attention: Xiaomi can block bootloader unlocking on new devices for 7-30 days after linking your account. This deadline cannot be circumvented legally.

The third stage is choosing the firmware. Official versions are downloaded from the website Miui Download. For custom ROMs (for example LineageOS or Pixel Experience) use the forums XDA Developers or 4PDA. Make sure the firmware is correct for your model! Redmi Note 10 Pro i Redmi Note 10 Pro Max have different encodings, and installing the wrong version will lead to irreversible damage to the camera module or modem.

Method 1: Reinstalling Android via Recovery (without a PC)

This is the simplest method that does not require connecting to a computer. It is suitable for restoring the system after crashes or removing viruses, but does not helpif:

• 🚫 The device does not turn on or is stuck on the logo Mi.
• 🚫 The area is damaged boot or recovery.
• 🚫 A downgrade of the MIUI version is required.

Instructions:

1. Turn off the phone. Press Volume up + Powerto enter Recovery Mode.
2. In the recovery menu, select a language (if available) and go to Wipe & Reset → Wipe All Data (full reset).
3. Return to the main menu and select Install update.zip to System. If the firmware file (update.zip) is in the root of the memory, the system will find it automatically.
4. Confirm the installation and wait for completion (5-15 minutes). Do not interrupt the process!

If there is no firmware installation item in recovery, then your device uses stock recovery without advanced functions. In this case, go to method c Fastboot.

⚠️ Attention: On some models (Xiaomi 13, Redmi K50) after resetting via recovery, you may need to repeat authorization Mi Account to unlock the device. If you do not remember the password, the phone will become unusable!

Method 2: Firmware via Fastboot (using Mi Flash Tool)

This method is suitable for “bricked” devices (devices that do not turn on or are stuck at boot), as well as for installing official firmware on an unlocked bootloader. You will need a Windows computer and an original USB cable (do not use cheap Chinese cables - they can interrupt data transfer!).

Step-by-step guide:

1. Download Mi Flash Tool c official website and unzip the archive. Install drivers from the folder Driver (if Windows does not pick them up automatically).
2. Download the firmware in format .tgz for your model. Unpack it into a folder without Cyrillic characters (for example, C:\MIUI\proshivka).
3. Turn off the phone. Press Volume down + Powerto enter Fastboot. Connect the device to the PC.
4. Run Mi Flash Tool, click Select and specify the path to the unpacked firmware. Click Refresh —the app should detect the device.
5. At the bottom, select the firmware mode:
   • Clean All — complete cleaning (recommended in case of failures).
   • Save User Data — saving user data (risky in case of critical errors).
   • Clean All and Lock — cleaning + bootloader locking (only for experienced users!).

If Mi Flash Tool gives an error Anti-rollback, this means that you are trying to install the firmware version below the minimum allowable for your device. Xiaomi introduces such restrictions to prevent the installation of outdated (and potentially vulnerable) versions. This can only be bypassed through EDL-mode, but this is risky and requires an authorized developer account.

Method 3: Installing custom firmware (TWRP + Custom ROM)

Custom firmware (LineageOS, Pixel Experience, crDroid) give more freedom: no advertising in MIUI, current security updates, pure Android without a shell. However, their installation requires:

• 🔓 Unlocked bootloader.
• 🛠 Installed custom recovery (TWRP or OrangeFox).
• 📥 Compatible firmware for your model (check at XDA or 4PDA).

Installation instructions TWRP and custom firmware:

1. Download TWRP for your model with official website (file with extension .img).
2. Rename it to twrp.img and place it in the folder with ADB (download Platform Tools from Google).
3. Enable USB debugging in the developer settings and connect the phone to the PC.
4. Open the command line in the folder with ADB and run:

   adb reboot bootloader
   fastboot flash recovery twrp.img
   fastboot reboot recovery

5. B TWRP make a backup of the current system (Backup → Select Partitions → System, Data, Boot).
6. Flash custom firmware (Install → Select ZIP file) and required install GApps (Google services), if they are not included in the ROM.
7. Clear the cache (Wipe → Dalvik / ART Cache, Cache) and reboot.

The first download of custom firmware may take up to 10 minutes. If the device is stuck on the logo for more than 20 minutes, something has gone wrong. Frequent errors:

• 🔴 Bootloop (cyclic reboot) - usually due to incompatible firmware or lack of GApps.
• 🔴 No SIM - problem with the modem, requires firmware of a separate file vendor or firmware.
• 🔴 Wi-Fi/Bluetooth do not work - no proprietary drivers from Xiaomi.

⚠️ Attention: Installing custom firmware will void the Xiaomi warranty. In addition, some functions (for example IR blaster or Game Turbo) may not work correctly or be absent altogether.

Method 4: Recovery via EDL (for "bricks")

EDL (Emergency Download Mode) is an emergency firmware mode that is used when the device does not respond to Fastboot or Recovery. It requires a special cable (EDL-cable) or contact closure on the board, as well as an authorized account Xiaomi (for new models).

⚠️ Warning: Incorrect use EDL may permanently damage the memory module (eMMC), making the phone unsuitable for repair. This method is recommended only in extreme cases!

Brief instructions:

1. Download the firmware in format .mbn (for example, with 4PDA).
2. Install the driver Qualcomm HS-USB QDLoader 9008 (manually through the device manager).
3. Move the phone to EDL:
   • For older models: hold Volume up + Volume down + Power while connected cable.
   • For new ones: you will need to disassemble the device and close the contacts EDL on the board (look for instructions for the specific model!).

After successful firmware through EDL the bootloader will be blocked and all data will be erased. This method is often used in service centers to restore bricks, but at home. conditions are fraught with risks.

Typical mistakes and how to avoid them

Even experienced users sometimes make mistakes when reinstalling Android on XiaomiHere are the most common:

Another common problem — loss of IMEI after flashing. This happens if the partition is damaged nvram or modem. You can restore IMEI through the engineering menu (##4636##) or specialized utilities like SN Write Tool, but this requires rootrights and knowledge of the original IMEI values.

If after reinstalling Android you lost Google services, most likely you forgot to flash GApps. site OpenGApps (choose the version that matches your firmware: ARM64/ARM and Android 12/13/14).

What to do after reinstalling Android

Successful firmware is only half the battle. After the first boot you need to:

1. Recover data from a backup copy (if you made a backup via TWRP or Mi Cloud).
2. Update all applications via Google Play.
3. Check the operation of key functions:
   • 📶 Mobile network and calls.
   • 📷 Camera (check all modules!).
   • 🔋 Charging and determining the battery level.
   • 🎧 Sound through speakers and headphones.

Settings → Applications → Manage applications → Show all → Disable:
- MSA (Mi System Ads)
- Miui Daemon
- Analytics

If you have installed custom firmware, pay attention to:

• 🔄 OTA updates: many custom ROMs support over-the-air updates, but sometimes they need to be installed manually.
• 🛡 Security: lack of monthly patches from Google increases the risk of vulnerabilities.
• 🎯 Performance: some firmware (for example, Pixel Experience) may work slower on weak devices (Performance batteriesRedmi 9A).

If after updating your phone your phone starts to discharge faster, check:

• 🔋 Background processes V Settings → Battery → Battery Usage.
• 🔄 MIUI optimization (if you are using official firmware). Disable Automatic optimization in the battery settings.
• 📡 Mobile network: switch from 5G to 4G if the coverage is unstable.
