Instructions

Using WinRAR or similar software, extract the RAR package that you downloaded. Extract the archive into a folder on your computer, preferably the Desktop, where you can easily find the extracted file. You should be getting one file with a *.tar.md5 extension.
Extract Odin3 v1.7.zip into a folder on your computer.
Turn off your phone and make sure that it is not connected to your computer.
Boot your Infuse 4G into recovery by holding down the Volume Up, Volume Down, and Power buttons at the same time. When you see the Samsung logo, release the Power button. In recovery, use the Volume buttons to navigate and the Power button to select options.
Select the Wipe All User Data option. This won’t affect any files on your SD card. Confirm data wipe by selecting Yes on the next screen.
Select Wipe All Cache Data.
Select Reboot system now and allow your phone to reboot normally.
After the phone has completely booted, turn it off completely again.
On your computer, run Odin3 by double clicking on Odin3 v1.7.exe.
Click the PDA tab in Odin3 and select the *.tar.md5 file that you extracted from the RAR package.
Connect the USB cable to the computer.
While holding down the Volume Up and Volume Down buttons on your phone, plug the other end of the USB cable into your phone. This will place the phone in Download Mode. In Odin3, you will see an “Added!” message, indicating that the device is recognized. If you do not see this message, reinstall the device drivers or check that you enabled USB debugging.
Click START in Odin3 to start flashing the kernel. Wait for it to finish.
Once the flashing is done, your device will automatically reboot. You should get a “PASS” message on the Odin3 window, indicating that the flashing was successful.
However, if you get a “FAIL” message on the Odin3 window, disconnect the phone from the computer, close Odin3, remove your phone’s battery, re-insert the battery, start over from step 3.
