Here's how to root the Samsung Galaxy S5 (SM-G900F) step by step

Before we do that, however, we'll list a bunch of disclaimers, or warnings if you like. 

For starters, and do make sure you understand the importance of this, only try rooting the international Galaxy S5 model -- the SM-G900F. It won't be long until most any variant gets a root method, but for the time being the G900F is the only one that won't catch fire if you root through this method. Secondly, keep in mind that this will increase your phone's so called 'flash counter', which is really a (removable) obstacle to warranty service if you modify any of the software on your device. Lastly, rooting will also trip a Knox security flag.

With that out of the way, let's get cracking.
