Update

Im rooted, so should I let the system update or no?

probably not, most people who are rooted have ota's blocked

how do I block OTAs?

if your rooted, there already blocked!!!

# mount -o remount,rw /dev/null /system
# mv /system/recovery-from-boot.p /system/recovery-from-boot.p.bak
# mv /system/etc/install-recovery.sh /system/etc/install-recovery.sh.bak

i got that from this website

Installation | Sholes

blocking updates requires renaming the otacerts file.

Search for otacerts on the forum and should find the directions listed.

not necessarily, there are still ways to root and not properly block ota's, if you do what i posted from sholes.info it will assure that you have them blocked

It failed soo it seems mine were already blocked. Thanks for the help anyways Bro.

no problem, never hurts to be sure
