Step 1: Extract Firmware zip file via WinRAR/7-Zip or WinZip to obtain a .tar.md5 file and some other optional files.

Step 5: Launch Odin on computer as an Administrator.

Step 9: After ensuring that Step 7 and Step 8 are done correctly, hit the Start button to begin installing the firmware.
Step 10: After the firmware is installed, the phone will reboot and soon a PASS message with green background appears in the left-most box at the top of Odin. It is now safe to disconnect the USB cable and remove the phone from computer.
