2. Preparing your smartphone for the update: 5 mandatory steps

Before installation Android 12 you must perform several critical steps to avoid data loss or failures process. Even if you update via OTA, preparation will take no more than 15 minutes, but will save hours on recovery in case of an error.

Create a backup copy of your data|Charge the battery to 60% or more|Free up at least 5 GB of memory|Disable screen lock (PIN/pattern)|Make sure you have a stable Internet connection. (for OTA)

-->

Let's consider each item in more detail:

  • 🔋 Battery charge: The minimum level is 60%, but it is better to charge to 80-100%. If discharged during the firmware, the device may turn off, which will lead to soft-brick (re-flashing via PC).
  • 📱 Backup: Use Settings → Advanced settings → Backup and reset or third-party tools like Swift Backup (root access required). data-i="103">Settings → Additional settings → Backup and reset
    • Contacts (export to .vcf)
    • Photos and videos (on PC or cloud)
    • List of installed applications (App List Backup)
    • Wi-Fi and Bluetooth settings
  • 🗃️ Free up memory: Update requires 5-6 GB of free space. spaceDelete unnecessary files or transfer them to a memory card (if supported). Check the free space in Settings → Memory.
⚠️ Attention: If you are using data encryption (enabled by default on some models), disable it before flashing the firmware via Recovery. Otherwise, after the update, the device may not boot, requiring a full reset.

For users planning installation via Fastboot or custom recovery (TWRP):

  • 🔓 Unlock bootloader (bootloader) via official tool Realme Unlock Tool. This erases all data!
  • 🛠️ Install ADB and Fastboot on PC (instructions below).
  • 📥 Download the correct firmware version for your model (links in the next section).
💡

If your device Realme does not see the OTA update, try changing the region in the settings. To do this, use the application Realme Region Changer (an unlocked bootloader is required).

3. Method 1: Over-the-air (OTA) update - the safest method

If your device officially supports Android 12, the easiest way is to update via OTA (Over-The-Air). delay - sometimes up to several months after release.

Instructions for updating via OTA:

  1. Connect to stable Wi-Fi network (update weighs 2-4 GB).
  2. Go to Settings → About phone → Software update.
  3. Click Check for updates. If available Realme UI 3.0, start downloading.
  4. After downloading, click Install now or Install at night (recommended).
  5. Wait for the reboot (it will take 10-20 minutes). Do not interrupt the process!

If the update does not appear, try the following:

  • 🔄 Forced check: Click on the logo Realme UI in the update menu 5-7 times in a row This sometimes works for hidden ones. updates.
  • 📡 Change server: Use a VPN with a region India or Europe - there updates often appear earlier.
  • 📦 Manual OTA installation: Download the update file for your model from the website Realme and install it via Settings → Software update → Local update.
What to do if the OTA update is stuck?

If the update process is stuck at the "Install..." stage for more than 30 minutes:

1. Hold the power button for 10-15 seconds to force a reboot.

2. If the device does not turn on, press Power + Volume up to enter Recovery.

3. Select Wipe data/factory reset (this will delete all data!) and repeat the installation.

⚠️ Attention: On some models (Realme 7 Pro, Realme X7), after updating via OTA, communication with the mobile network may be lost. This can be treated by resetting the network settings in Settings → Mobile network → Reset settings.

4. Method 2: Manual update via Recovery - for experienced users

If OTA is not available, but your model supports Android 12, you can install the firmware via Recovery. This method requires downloading the official update package and installing it manually. Suitable for devices with a locked bootloader.

Step-by-step guide:

  1. Download the correct firmware version for your model from of the official website. The file must have the extension .ozip.
  2. Move the file to root folder of the internal memory (not folders!).
  3. Turn off the smartphone and hold down Power + Volume Down to enter Recovery.
  4. Select a language (usually English by default).
  5. Go to Install from storage → specify the downloaded file .ozip.
  6. Confirm the installation and wait for completion (10-15 minutes).
  7. Select Reboot system now.

Important nuances:

  • 🔗 Checking the file: Make sure the file name contains the version RMX of your model (for example, RMX3085_11_A.12 for Realme 8 Pro). An incorrect file will lead to bricking!
  • 🔄 Reset data: In most cases, the data will be saved, but on some models (Realme X50 Pro) a reset is required Wipe data after installation.
  • 🛡️ Backup IMEI: On rare devices, IMEI is reset after flashing. To avoid problems, save it through the engineering menu (##4636##).
Model Link to firmware (example) File size Required reset?
Realme GT (RMX2101) RMX2101_11_C.12 3.2 GB ❌ No
Realme 8 Pro (RMX3081) RMX3081_11_A.12 3.5 GB ⚠️ Sometimes
Realme 7 Pro (RMX2170) RMX2170_11_C.12 2.9 GB ✅ Yes
⚠️ Attention: If after installation via Recovery the device boots into an endless loop (bootloop), follow these steps:
  1. Log in Recovery again.
  2. Select Wipe data (full reset).
  3. Reinstall the firmware again.

If the problem persists, you will need to flash the firmware via Fastboot (method 3).

5. Method 3: Firmware via Fastboot - for unofficial firmware and recovery

This method is suitable for:

  • 📱 Devices that do not receive official update (for example, Realme X2 Pro).
  • 🔧 Recovery after unsuccessful firmware (bootloop, brick).
  • 🛠️ Installation of custom firmware (LineageOS, Pixel Experience).

For firmware via Fastboot you will need:

  • 💻 Computer with installed ADB and Fastboot (download in Android SDK).
  • 🔌 Cable USB Type-C (preferably original).
  • 🔓 Unlocked bootloader (instructions below).
  • 📦 Firmware in format .ozip or .img for your model.

Instructions for unlocking the bootloader:

  1. Enable Developer mode: go to Settings → About phone and click 7 times on Build number.
  2. Activate USB debugging i OEM unlocking in Settings → System → For developers.
  3. Connect your smartphone to the PC and run the command: 
    adb reboot bootloader
  4. In the bootloader, run: 
    fastboot flashing unlock

    and confirm unlocking on the phone (this will delete all data!).

Installing the firmware via Fastboot:

  1. Unpack the firmware into the folder with fastboot.
  2. Connect the phone in the mode Fastboot (Power + Volume Down).
  3. Run the command to check the connection: 
    fastboot devices

    (the serial number of the device should be displayed).

  4. Run the firmware (example for Realme GT): 
    fastboot flash --slot=all boot boot.img

    fastboot flash --slot=all dtbo dtbo.img
    

    fastboot flash --slot=all system system.img
    

    fastboot flash --slot=all vendor vendor.img
    

    fastboot reboot

💡

Firmware via Fastboot is the only way to restore the device after a “brick” (complete inoperability). However, this method requires strict adherence to commands and compatible firmware.

To install custom firmware (LineageOS, Pixel Experience):

  1. Download the firmware from the site XDA Developers (check compatibility with your model!).
  2. Install custom recovery TWRP: 
    fastboot flash recovery twrp.img
  3. Reboot into TWRP (Power + Volume up) and install the firmware via Install.
⚠️ Attention: Custom firmware can lead to:
  • Loss of support Widevine L1 (Netflix, Disney+ in low quality).
  • Problems with NFC and mobile communications (on some models).
  • Failure SafetyNet (banking applications will not work).

To solve these problems, additional configuration is required (Magisk, Universal SafetyNet Fix).
