complete noob here.Can i still root my phone with out any back up? what can i do after i root it?can i delete any pre-stalled app i have no use for?
Yes you can root your phone without a backup, although it's not advisable. If you happen to soft-brick your phone and have to do a factory reset, you would lose all your data (texts, pictures, etc.) at the least. And yes, you can delete or freeze pre-installed apps. You should search for a list of which apps are safe to remove for your model of phone first, and freezing apps is preferable to deleting them (that way you can thaw them out if freezing them caused problems with your phone - way easier than trying to re-install) search Google play for apps that will let you freeze apps.
