For the last couple of months, Samsung - as a part of routine software update to their flagship devices - has been releasing the official Android 5.0 Lollipop OS to its Galaxy S5 in stages to select regions.

Tech-savvy users, who are not happy with the custom Touchwiz UI and all the bloatware that accompany the official Android 5.0 Lollipop, can unlock their Samsung Galaxy S5 model using the Chain Fire's CF-Auto-Root application tool.

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 customization options. For easy rooting experience, we will be using the Chain Fire's CF-Auto-Root application tool in this tutorial.

We would also like to remind our readers that installing custom ROM on devices is like using double-edged sword. Though firmware gives 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)

  • This Rooting procedure has to be carried on Samsung Galaxy S5 SM-G900H (with Exynos Octa-core) 3G model running on official Android 5.0 Lollipop (build number: XXU1BOA7) firmware only; if tried on other devices, it might get bricked [To check your device model: Go to Settings >> About phone >> model number]
  • Rooting of devices sometimes (if procedure is not followed properly) leads to complete data wipe out, so make sure to back all the data. [Install Clockwork Mod (CWM) Recovery/ TWRP in the smartphone to save the data].
  • Users make sure they have installed USB drivers on the PC, or else your phone (Samsung Galaxy S5) will not be recognized by the computer.
  • Make sure your device has more than 80 per cent battery, or else there is a chance of the smartphone getting temporarily bricked in case the installation process is interrupted mid-way.

[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. Hence, users are advised to proceed with caution.]
