Early this week, Samsung released the official Android 5.0 Lollipop OS to its flagship smartphone, Galaxy S5, in select regions as a part of routine software update to their flagship devices.

However, tech-savvy users who are interested in rooting can unlock their Samsung Galaxy S5 LTE (SM-G900F) model using root application tools available in the Internet.

Rooting enables users to install custom ROMs, third party applications of their choice and also perform tweaks in the settings to enhance the device's performance and add more customisation options. For easy rooting experience, we will be using the Chain Fire's CF-Auto-Root application tool in this tutorial.

We like to remind our readers that installing custom ROM devices is like a using double-edged sword. Though firmware give users more control over the smartphone, the company warranty will stand void and will no longer be liable for future updates.

[Note: Warranty can be restored by flashing the device with stock-ROM]

So we advise users to first go through the whole tutorial thoroughly and then go ahead with rooting procedure.

Prerequisites (things to remember before installing Custom ROM)

[Disclaimer: This procedure is very technical and should be performed by a person with sound knowledge of rooting (or manual software installation) Android devices. If the step-by-step installation process is not followed properly, there are chances of the smartphone getting bricked or being permanently irreparable. International Business Times, India Edition cannot be held responsible for any damage or claims from readers if the procedure does not yield the required results or if the smartphone is bricked.
