hi i have done everything, Step 1.
Ensure that your phone is fully charged.
On your phone, go to... Settings > Applications > Developement > USB debugging and check the box.
Put your phone into Download mode by turning it off completely and then press and hold the following buttons... Volume Down + Home (centre hard key) + (lastly) Power. Continue to hold these buttons until your phone boots into the Warning! screen asking you to press volume up if you want to continue or volume down to cancel. Press volume up.
Right click on Odin3 v1.85 and select, "Run as Administrator", to open it.
With Odin3 v1.85 displayed on your PC screen, click on the PDA button and navigate to the CF-Root Tar .zip file, that you placed on your home screen, and select it.
Make sure that Re-Partion is unchecked and that Auto Reboot, F.Reset Time and PDA are checked and that the PDA box now contains your .tar file.
Connect your phone, still in Download mode, to the PC using the USB lead. If you have successfully connected to Odin3 v1.85 you should see the ID:COM box in Odin turn yellow.
