im slowly learning about this stuff and have never really strayed from computers and im really stuck. My golden rule is to always have a life line backup system image or factory reset to boot from incase of failure. i've seen some stuff on the SBF file and if some one could explain if that file completely resets the phone to factory because rooting only effects the sbf or if its just wiping out everything and clean reinstalling.. also is it possible to make a system image or other form of backup PRE-ROOT so i can wreck my phone knowing it's fixable. This would be nice incase of crashes even if i decide not to root. Any help is appreciated!!!!
