For those of you thinking about rooting your Note 3, you can use these Galaxy Note 3 Windows USB drivers, which will work for ODIN and Android ADB Debugging. These are official Samsung drivers pulled straight from Samsung KIES software. You don’t have to install the whole KIES software (which can take up a lot of space on your hard disk) instead install these drivers, which will only install the USB drivers you need.
These drivers work on all Windows operating systems including Windows XP, Window Vista, Windows 7, Windows 8, and Windows 8.1. Works for both 32-bit and 64-bit systems.
To install, simply download and double-click on the EXE file to install drivers. Make sure you reboot your computer after installing drivers!
