Guide to unlock bootloader, root and install CWM recovery on Nexus 5.

Google's new Nexus 5 comes with locked bootloader. Those looking for a method to unlock the bootloader of the Nexus smartphone may follow our step-by-step guide below. Unlocking the bootloader will enable users to perform multiple functions such as installing custom ROM, custom recoveries, kernel and rooting.

IBTimes UK reminds its readers that it will not be held responsible for any damage to the device. Users are also advised to verify that their devices meet the following requirements.


1) Install USB Driver for Nexus 5 to transfer files between the Android device and the computer.

2) Enable USB Debugging Mode on the phone to connect the Android device with computer and use the Android SDK with it. [Press Menu>> Settings>> Applications. From there navigate and click on Development option and check USB Debugging Mode.]

3) As the tutorial might wipe out all the data of the phone, create a backup. If the device is having any custom recoveries such as CWM/TWRP already installed, then back up data using the recovery.

4) The Nexus 5 should have above 80% of battery charge. If the phone goes off suddenly, due to low battery while installing a custom ROM, flashing an official firmware or installing mode, the phone might get bricked or go dead permanently.

5) This tutorial has been performed on Windows but anyone familiar with Fastboot on Mac or Linux can perform this as well.

6) The bootloader unlock method works only on Nexus 5. Applying this to any incorrect variant is likely to brick the device.

7) Unlocking the bootloader will void the device of its warranty.
