I own an Nvidia Shield tablet and Nvidia has released an update to Android 5.1. I have a rooted device and may upgrade soon. So I have some questions:

Will I be able to install this while rooted?

If I tried, could it brick my device?

If I installed it would it unroot me?

If so how would I re-root? I rooted by unlocking the bootloader and installing CWM by the instructions at http://www.ibtimes.co.uk/how-root-nvidia-shield-tablet-android-5-0-lollipop-install-cwm-recovery-1481041. 

I unlocked rhe bootloader, if I re-rooted would it erase my data or brick me?
