How to install Android 13 on a phone

Installing a new Android version can be straightforward if your device is supported, but it may also involve manual flashing for advanced users.

  • Back up all important data (installing may wipe your phone)

  • Make sure your phone’s bootloader and warranty terms are understood—manual flashing can void warranties

  • Your phone must have at least 50% battery

  • Use the original USB cable for best results.

Check Compatibility

Not every device supports Android 13.

  • Google Pixel phones officially support Android 13 (Pixel 4 and newer).

  • Other brands (Samsung, OnePlus, Xiaomi, etc.) roll out updates in phases.

📌 To check:

  • Go to Settings → System → System Update. If Android 13 is available, you’ll see a download prompt.

3. Method 1: Install Android 13 via OTA (Recommended)

This is the safest and easiest way.

  1. Connect to Wi-Fi

  2. Open Settings → System → System update

  3. Tap Check for update

  4. If Android 13 is available, tap Download and install

  5. Wait for installation → phone will reboot → Android 13 installed.

Method 2: Sideload Android 13 OTA (Manual Update)

If the OTA hasn’t reached you yet but your phone supports it, you can manually sideload.

Requirements

  • A PC with ADB & Fastboot tools installed

  • USB cable

  • Download the official OTA update file from Google’s developer site.

Steps

  1. Enable Developer Options:

    • Go to Settings → About phone → Tap Build number 7 times

    • Then enable USB debugging in Developer Options.

    • Reboot into Recovery Mode:

      • Power off phone → Hold Power + Volume Down until bootloader appears.

      • Use volume keys to select Recovery Mode → press Power.

  2. Connect to PC and verify connection:

    adb devices

  3. Apply update via ADB sideload:

    adb sideload ota_filename.zip

  4. Wait until the process finishes → reboot → Android 13 installed.

5. Method 3: Flash Factory Image (Advanced)

This is a clean install and will wipe your phone.

Requirements

  • A PC with ADB & Fastboot tools

  • Official factory image for your phone from Google’s factory images site.

  • Bootloader unlocked.

Steps

  1. Unlock Bootloader (this will erase all data):

    fastboot flashing unlock

  2. Extract Factory Image: Download and unzip the file.

  3. Run Flash Script: Inside the extracted folder, run:

    • On Linux/Mac:

      ./flash-all.sh

    • On Windows:

      flash-all.bat

  4. Phone will reboot → fresh install of Android 13.

6. After Installation

  • Go through setup wizard

  • Restore backup if you created one

  • Check for security updates in Settings.
