I tried rooting my phone a few months back and followed the instructions perfectly but when i go on titanium backup on my phone it tells me my phone hasnt been rooted. I then try and see if i can do a software update to the new jelly bean but it says that i cant. Is it safe to do a factory reset on my phone or will my phone brick? if it will brick are there anyways to correct this so i can go back to a standard phone and try this again.

Did you flash a Recovery? Do you have an app called "Super User"?

Try the "Root with ClockWorkMod" section of this guide, that should do it!
