How to update Galaxy S2 to official Android 4.0.4 ICS XXBLFB Firmware
- Download the XXBLFB official firmware file from HERE.
- Extract the zip file contents into a single folder. You should get a file with the ‘.tar.md5’ extension.
- Next, download Odin 3.04 zip file from HERE. This is the application you’ll use to flash the firmware files.
- Extract Odin contents and save the folder on your computer’s desktop.

- Open the Odin folder and launch the Odin.exe file.
- Now you should connect your Galaxy S3 to your computer. Odin will display an ‘added’ message alert. If it doesn’t say ‘added’ then the USB drivers for your phone aren’t installed and you should return to the preparation guide and install them. Also, remember to enable the USB Debugging option as otherwise Odin cannot apply the new firmware files.
- Next, click the PDA tab in ODIN and navigate to the firmware ‘.tar.md5’ file and select it. It should be the file you extracted at step 2. Don’t edit any default Odin settings as that might result in a failed attempt to flash the new firmware. The ‘Re-partition’ box should be un-ticked. If everything is set move to the next step.
- Click the ‘Start’ button and wait until ODIN completes the update.
- Odin now starts to apply all the official XXBLFB firmware files on your smartphone and when the process is complete you should notice the PASS message displayed in Odin’s window.
