how to avoid automatic updates?

[gierso]

is there a way to avoid automatic updates?
i keep seeing my version went from rel 7 to rel 11 without my confirmation..

i love they constantly update, but im afraid in some update the power will fail while updating,

also i think i cant root anymore in REL11 so i want to stay in rel11 in the event of the root method catching up with the versions

It doesn't automatic update if you shut it all the way down at night.
