If you are having trouble rooting your Galaxy S5 no worries, developer "Sharpie603" has released an all in one toolkit that will make rooting among other mods super easy. This toolkit will install usb drivers, root device, install busybox, install safestrap, install supersu, de-bloat and re-bloat the device, enable/ disable call recording, backup pictures/video/music, boot animation, and more. There will also be more options added to the toolkit soon. Running the tookit is as easy as clicking "toolkit.exe". One of the most valuable uses of this toolkit is the ability to add and remove bloat since you will need to replace bloat before installing any OTA update. Head to the link below for the download.
