How to downgrade to One UI 2.5 on Galaxy S20

Downgrade to One UI 2.5 from One UI 3.0

Recently, Samsung released one beta version of UI 3.0 based on Android 11 for the Galaxy S20 series. The new One UI 3.0 brings many changes along with some new UI changes as well. If you own a Galaxy S20, S20+, or S20 Ultra and want to try out the Beta build of One UI 3.0, here is the link for everything. If you are already running one UI 3.0 and found it buggy or your apps aren’t fully supported, then there’s always a way to downgrade to the stable version. So if you want to downgrade to One UI 2.5 stable Android 10 on your Galaxy S20, below is the download link and the steps to follow for downgrading it. 

The latest stable version of Galaxy S20 is the Android 10 One UI 2.5 with a build number ending with “BTIJ.” So to downgrade to one UI 2.5, you would need this build number file. Also, it can vary from region to region, but we have the link for every region. Again, do note that downgrading from Beta to a stable version will wipe your data, so make sure to backup everything before proceeding.

  1. Download Odin on your PC.
  2. Download ADB and fastboot on your PC and install it.
  3. Also, Download the required downgrade file from the above link and extract the zip file.
  4. After installation of ADB, open it, and connect your phone via USB cable.
  5. Allow USB Debugging on your phone from the developer’s option.
  6. Now in the ADB command Prompt, type “adb reboot recovery.”
  7. Wait for your phone to boot into recovery mode.
  8. Using the volume button, navigate to download mode, and then press the power button.
  9. Now open Odin, click on the BL button, and select a file that starts with “BL” inside your extracted firmware folder.
  10. Next, click on the ‘AP’ button in Odin and choose the AP file inside your extracted firmware folder. Click on the ‘CP’ button, select the CP file inside your extracted firmware folder. Click on the ‘CSC’ button, choose the HOME_CSC file inside your extracted firmware folder.
  11. Make sure you choose the HOME_CSC and not the CSC file.
  12. Click on the start button when everything you are ready.
  13. The installation will begin and should take around 15-20 mins.

Do note that if the bootloader is advanced on the new build, then Odin won’t work, and you won’t be able to revert to the older builds. If you get stuck somewhere in between the process you can always join our telegram group of S20 series. We would be happy to help you. Join us on Telegram.
