1) Download CF-Auto-Root file for S3 bearing the file name File name: CF-Auto-Root-m0-m0xx-gti9300.zip

    

2) Download Odin3_v3.07 and switch off the handset.

3) Press Volume down and power buttons simultaneously until the Android icon with a warning triangle appears on the screen. Press Volume up to start the download mode.
