Steps to install Android 9 Pie on Samsung Galaxy A20

  • Extract the INS-A205FXXU1ASC3.zip firmware file on your PC.
  • Switch off your mobile completely until it vibrates.
  • Boot your phone into downloading mode.
  • For that, press and hold Volume Down key + Power Button simultaneously.
  • Leave both the keys as soon as you see the following warning message.
  • Simply press the Volume Up button to continue.
  • This is how you can boot your device into download mode.
  • With USB cable, connect your mobile to PC.
  • Open the ‘Odin Multi Downloader3-v3.13.1′ tool.
  • Verify whether the ID: COM section in Odin flash tool is turned light blue or not.
  • Also, verify if an Added message is shown in the message box window or not.
  • If such a thing doesn’t happen then it’s a problem with mobile drivers.
  • Hence fix USB device not recognized error on your computer.
  • Check Auto Reboot and F.Reset Time options. Keep the rest of the options as they are.
  • Click on the BL button present on Odin and select the ‘BL’ file from the extracted firmware package.
  • Similarly, click on the CP button and select the ‘CP’ file from the firmware package.
  • Next click on the CSC button and open firmware file with ‘HOME_CSC’ in its name.
  • HOME_CSC contains instruction that allows Odin to only wipe cache while Normal CSC contains an instruction to wipe out complete data. But when a downgrade is done (example: from Pie back to Nougat) a factory reset is a must. So use normal CSC at that time.
  • Finally, click on the AP button and select the ‘AP’ file from the firmware package.
  • The AP file will take little time to load. So do not panic.
  • We will begin the process now. Hence, press Start button present on the Odin flash tool.

  • Your mobile will restart automatically. Do not disconnect it from the computer.
  • As soon as the flashing finishes, the ID: COM section will show a Pass message.
  • This will confirm that your Samsung Galaxy A20 SM-A205F is successfully upgraded to official Android 9 Pie A205FXXU1ASC3 firmware.
