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.
