Not long ago latest Android tablets and smartphones have begun to get the latest Android 4.1 Jelly Bean operating system. For example, Nexus smartphones and tablets are already updated. If we take as an example Nexus 7, then we’ll see that new theme allows working not only in a portrait mode, but in a long-awaited landscape mode as well. Notification board has also been changed. Android developers have done a great job and have created the fastest mobile platform which is at the same time is very stable.
But you should be aware of the fact that if you have got root rights earlier for your device, then after Jelly Bean update the ‘superuser’ rights will disappear. The same is with custom recovery. In general, after the update you’ll get an absolutely new device with new capabilities. This instruction is for saving the installed recovery and root rights.
Here’re the instructions on how to install an update on your Nexus tablet without losing root rights. Take into consideration the fact that though this method works on all devices, concrete steps and actions may differ, especially if a custom theme is installed (like CyanogenMod 10).
How to save root rights after Android update
