Official Stock Firmware Galaxy S9+
Official Stock Firmware Galaxy S9+

1) Download Odin v3.13.1 – Link

2) Extract the firmware file you just downloaded. You should get 5 files:

  • AP (System & Recovery)
  • BL (Bootloader)
  • CP (Modem / Radio)
  • CSC_OXM (OXM CSC file, will wipe your phone)
  • HOME_CSC_OXM (OXM CSC file, will NOT wipe your phone)

3) Add each file to it’s respective field in Odin v3.13.1. Use CSC_OXM if you want to do a clean flash and HOME_CSC OXM if you want to keep your apps and data.

4) Reboot your phone in Download / Odin mode with the following button combo:
POWER + VOLUME DOWN + BIXBY

5) Once in download mode, connect your phone to the PC, preferably using the original USB cable you got with your phone. Odin should detect your device and a blue box will show up with the COM port number.

6) Do NOT tick any extra boxes. The only options to be ticked are F.Reset Time and Auto-Reboot. 

7) Click the start button, wait for Odin to say ‘PASS’. Once the flash is complete, your phone will reboot.
