Default update 68 or any update and root shield

i tried to install update 68, the shield reboots get me to the screen with the android on its back, select the update install, then it errors out?
is the device being rooted causing the issue o the bootloader.

also if this or any small update installed correctly would i lose my root access,
if i lose root, will i always have to start from a factory rest and lose all my information to root it again.

thanks
