Root Galaxy Nexus Android 4.3 JWR66V Jelly Bean

Google’s (NASDAQ:GOOG) latest Android 4.3 Jelly
Bean mobile operating system was released last week for the company’s Nexus devices, such as the Galaxy Nexus I9250 and Nexus 4. If you have already updated your Nexus device to the new firmware, with the build number “JWR66V,” you can root the
device, which will allow you to run custom ROMs on it in future.

 

The rooting process explained here also installs the latest ClockWorkMod,
or CWM, recovery on Nexus devices, which will later help install custom firmware. The tutorial explained here covers the Galaxy Nexus I9250 and the Nexus 4.

Users must keep in mind that rooting the Android 4.3 Jelly
Bean firmware will void the device’s warranty. However, users can reclaim the warranty by re-installing the official firmware update again.

Here are some important aspects that users need to be aware of before performing the rooting process on their devices:
