Prerequisites and Essential Preparations for PixelExperience 12.1 on Galaxy A50 (A505FN)

Before diving into the installation process, it’s crucial to meticulously prepare your device and gather all necessary files. This groundwork will minimize the risk of errors and ensure a seamless transition to PixelExperience 12.1.

Backing Up Your Data: A Non-Negotiable Step

Data loss is a real possibility during ROM flashing. Back up all your important data – contacts, photos, videos, documents, and anything else you value. We recommend using multiple backup methods:

Remember: Verifying your backups is crucial. Ensure you can successfully restore data from each backup method before proceeding.

Unlocking the Bootloader: The Key to Custom ROMs

Unlocking the bootloader is mandatory for flashing custom ROMs like PixelExperience 12.1. This process removes the manufacturer’s restrictions, allowing you to install custom software.

Warning: Unlocking the bootloader will wipe all data from your device. Ensure you have backed up everything before proceeding.

  1. Enable Developer Options: Go to Settings > About phone > Software information. Tap “Build number” repeatedly (usually 7 times) until you see a message saying “Developer mode has been enabled.”
  2. Enable OEM Unlocking: Go to Settings > Developer options and enable “OEM unlocking.” If this option is missing, try inserting a SIM card and connecting to mobile data for a while.
  3. Boot into Download Mode: Power off your device. Then, press and hold the Volume Down + Volume Up buttons simultaneously while connecting your phone to your computer via USB cable. You should see a warning screen.
  4. Unlock the Bootloader using Odin:
    • Download and install Odin on your computer. (Search for “Odin Samsung Download” and obtain it from a reputable source like XDA Developers.)
    • Download the Samsung USB drivers and install them.
    • Open Odin.
    • In Odin, you should see your device recognized (a COM port will be highlighted).
    • Click the “Options” tab and ensure “Auto Reboot” and “F. Reset Time” are checked.
    • Click the “Log” tab.
    • Click the “Start” button. This will initiate the unlocking process. Your phone should reboot and display a warning screen.
    • Follow the on-screen instructions to confirm the bootloader unlock. This usually involves pressing the Volume Up button.

Important: The bootloader unlock process may vary slightly depending on your device’s firmware version. Consult specific tutorials for your exact firmware if you encounter difficulties.

Downloading the Necessary Files: PixelExperience and Recovery

You’ll need to download the following files:

Verify the integrity of the downloaded files: Check the MD5 checksum or SHA256 hash of each file to ensure it hasn’t been corrupted during download. This information is usually provided on the download page.

Installing ADB and Fastboot: Your Android Toolkit

ADB (Android Debug Bridge) and Fastboot are essential command-line tools for interacting with your Android device from your computer.

  1. Download ADB and Fastboot: You can download the Android SDK Platform Tools from the official Android Developers website. (Search for “Android SDK Platform Tools”)
  2. Extract the Files: Extract the downloaded ZIP file to a folder on your computer (e.g., C:\platform-tools).
  3. Add ADB and Fastboot to your PATH: This allows you to run ADB and Fastboot commands from any command prompt window.
    • Windows:
      • Search for “environment variables” in the Start menu.
      • Click “Edit the system environment variables.”
      • Click “Environment Variables…”
      • In the “System variables” section, find the “Path” variable and click “Edit…”
      • Click “New” and add the path to the folder where you extracted the ADB and Fastboot files (e.g., C:\platform-tools).
      • Click “OK” on all windows.
    • macOS/Linux:
      • Open your terminal.
      • Edit your shell configuration file (e.g., ~/.bashrc, ~/.zshrc).
      • Add the following line to the file, replacing /path/to/platform-tools with the actual path to the folder where you extracted the files: export PATH="$PATH:/path/to/platform-tools"
      • Save the file and run source ~/.bashrc or source ~/.zshrc to apply the changes.

Test ADB and Fastboot: Open a command prompt or terminal window and type adb version and fastboot version. If the commands are recognized, ADB and Fastboot are installed correctly.

Flashing TWRP Recovery on Your Galaxy A50 (A505FN)

With the prerequisites out of the way, let’s proceed to flashing TWRP recovery.

  1. Boot into Download Mode: As before, power off your device. Press and hold the Volume Down + Volume Up buttons simultaneously while connecting your phone to your computer via USB cable. You should see a warning screen.
  2. Open Odin: Launch Odin on your computer.
  3. Load the TWRP Image:
    • In Odin, click the “AP” button.
    • Select the TWRP recovery image file you downloaded (usually a .tar or .tar.md5 file).
  4. Disable Auto Reboot: In Odin, go to the “Options” tab and uncheck “Auto Reboot.” This is crucial to prevent the device from booting back into the stock recovery after flashing TWRP.
  5. Flash TWRP: Click the “Start” button. Odin will flash the TWRP recovery image to your device.
  6. Manually Boot into TWRP: Once Odin displays “PASS!”, immediately disconnect your phone from the computer. Then, press and hold the Volume Up + Power buttons until you see the TWRP logo. This is important to prevent the stock recovery from overwriting TWRP.

Troubleshooting TWRP Flashing:

Installing PixelExperience 12.1 via TWRP Recovery

Now that you have TWRP recovery installed, you can finally flash PixelExperience 12.1.

  1. Copy Files to Your Device: Connect your phone to your computer while in TWRP recovery. Copy the PixelExperience ROM, GApps (optional), and Magisk (optional) files to your device’s internal storage or an external SD card.
  2. Wipe Data: In TWRP, go to “Wipe” and then “Advanced Wipe.” Select “Dalvik / ART Cache,” “Cache,” “System,” and “Data.” Do not wipe Internal Storage or Micro SDcard unless you specifically intend to erase all data on those partitions. Swipe to confirm the wipe.
  3. Flash the ROM: Go back to the main TWRP menu and tap “Install.” Select the PixelExperience ROM file you copied to your device. Swipe to confirm the flash.
  4. Flash GApps (Optional): After the ROM is flashed, go back to the “Install” menu and select the GApps package you copied to your device. Swipe to confirm the flash.
  5. Flash Magisk (Optional): If you want to root your device, go back to the “Install” menu and select the Magisk APK file you copied to your device. Swipe to confirm the flash.
  6. Reboot: After flashing all the desired files, tap “Reboot” and then “System.”

First Boot: The first boot after flashing a custom ROM can take a while (5-10 minutes). Be patient and don’t interrupt the process.
