Important Note: Backup important files stored on internal SD card of your device, so that in case a situation arises requiring you to do a factory reset after flashing stock firmware, which might delete internal sd card too, your files will remain safe on PC.
- Extract/Unzip the Odin zip file, Latest Odin3 v3.09.zip on your computer (using 7-zip free software, preferably) to get this file: Odin3 v3.09.exe
- Extract/Unzip the Firmware zip file, I337MK2_Combined_Odin_Tar.rar on your computer (using WinRAR free software, preferably) to get this file: All-In-One-i337Mk2-tar.md5
- Move the firmware file, All-In-One-i337Mk2-tar.md5, in the same folder in which you extracted Latest Odin3 v3.09.zip (Just for your convenience, that is). So, now you’ll have the following files in that folder:

- If you have already installed driver, then uninstall them and re-install back.
