Being a Nexus device, the steps to root it are almost ridiculously simple, however some people like to have an automated process to complete the whole process. Noted Android developer and hacker Chainfire has released CF-Auto-Root for the Nexus 5 which will perform all the necessary functions to gain Root on your new phone.
Note:Any modifications made to your phone are done at your own risk and Ausdroid takes no responsibility for anything that occurs. Read ALL instructions before undertaking any process which changes your phone or devices default factory state.
A specific note before forging ahead – not that any Australians have on in hand as yet….or do you? – you’ll need to think about your bootloader as this will be unlocked as part of the process and will wipe your device if you haven’t already.
If you’re ready to go ahead, then you can download the CF-Auto-Root file from the Chainfire website. For instructions, you’d be best off checking the XDA page where instructions are available and we highly recommended that you do read them thoroughly before starting.
If you’re wanting to learn more about how to manually gain Root access on your Android device, then the XDA-Developers forum is also the best place to start your search.
