As a solution for this, you can manually download the official Android 11 firmware and flash it on your Galaxy Note 20. For this, you will need Frija. This is a tool with which you can download firmware files directly from Samsung’s servers. Here’s how.

  3. Open Frija, and enter the model number in the Model field.
  4. Now you need to enter the CSC code (region code). This is different for every carrier. For example, it is ATT for AT&T, VZW for Verizon, TMB for T-Mobile, SPR for Sprint, and XAA for unlocked variants.
  5. Click on Check Update. The tool will search for the latest firmware files and will display the latest one.
  6. Tap on Download. This will download the selected firmware on your computer.
