Step-by-Step Guide

Prepare Your PC:

Install Samsung USB Drivers.
Extract the Odin ZIP file to a folder on your computer.

Prepare the Firmware:

Extract the downloaded firmware ZIP file. You should see files with extensions like BL, AP (or PDA), CP, and CSC.

Boot Your Phone into Download Mode:

Power off your GALAXY S22 ULTRA SM-S908U.
Press and hold the Volume Down + Bixby buttons simultaneously.
While holding the buttons, connect the USB cable to your computer.
You should see a warning screen. Press Volume Up to enter Download Mode.

Flash the Firmware Using Odin:

Open the Odin executable file (Odin3 v3.13.1).
Connect your phone to your PC. Odin should recognize your device, and a "COM" port will turn blue.

In Odin:

Click the BL button and select the BL file from the extracted firmware folder.
Click the AP button and select the AP (or PDA) file. This is the largest file and may take some time to load.
Click the CP button and select the CP file.
Click the CSC button and select the CSC file. For a clean install, use the HOME_CSC file. For preserving user data, use the CSC file.
Important: Ensure that "Auto Reboot" and "F. Reset Time" are checked. Do not check "Re-Partition" unless you know exactly what you are doing.
Click the Start button.

Wait for the Process to Complete:

Odin will now flash the firmware onto your device. This process can take several minutes. Do not disconnect your phone during this process.
Once the process is complete, Odin will display a "PASS!" message, and your phone will automatically reboot.

First Boot:

The first boot after flashing may take longer than usual. Be patient.

Troubleshooting:

Odin doesn't recognize my phone: Reinstall Samsung USB Drivers, try a different USB port or try a different USB cable.
Stuck in a boot loop: Try flashing the firmware again. If the problem persists, you may need to flash a different firmware or seek professional help.
