The search engine giant, Google's Android team has already released the factory image for Google-LG Nexus and is slowly rolling out the update via OTA in phases.

Users, who have not received (via OTA) or installed the factory image, can root the Nexus 5 with simple CF-Auto-Root tool (developer, Chainfire).

Pre-requisite (things to remember before the rooting the smartphone):

  • Rooting enables users to install custom ROMs or third party apps of their choice and also be able to perform tweaks in the setting to improve the device's performance, though the user get more control over the smartphone, company's warranty stands void and will no longer be liable for future updates [warranty can be restored simply by flashing the device with stock-ROM].
  • Nexus 5 Bootloader must be unlocked
  • Rooting of devices leads to complete data wipe out, so make sure to back all the data.
  • Users make sure you have installed USB drivers on the PC to connect your Google-LG Nexus 5. [Download USB driver, here]
  • Make sure your smartphone has more than 80-percent battery.

[Disclaimer: This procedure is very technical and should be performed by a person with sound knowledge of rooting (or manual software installation) of Android devices. If the step-by-step installation process is not followed properly, there are chances of the smartphone getting bricked or may even lead to the device 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 smartphones get bricked. Hence users are advised to proceed with caution.]
