How to restore Samsung Galaxy S Infuse 4G to Stock ROM

The following is a step by step process of restoring the Samsung Galaxy S Infuse 4G to stock ROM. Sometimes a factory reset does not fix the issue with the phone. You will then need to perform a restore to stock ROM to fully recover it. Or if your phone is bricked during flashing, restoring to stock ROM may also fix the issue. I have personally tried the below steps and it worked for me. 

• Make sure Samsung USB driver is installed on your PC
• Down load and unzip the file on your desktop
• Run Odin 1.7 (run as administrator if you are on Windows 7)
• Put the phone in download mode (Hold both volume keys and then connect to PC with USB cable)
• Odin will should detect the phone in several seconds and show a yellow bar with com port number
• Choose infuse.pit, PDA_UCKD5.tar.md5, PHONE_UCKD5.tar.md5 in appropriate fields
• Press start and it shall progress and then reboot the phone. Once it's done, odin will show a green bar with "passed" and the phone will reboot
• Congratuations, now you just flashed the phone to stock ROM
