There are a TON of FAQ's and information on this forum and the whole of AC about rooting. Everything tells you to read up on it first, always backup, know what you're doing.. etc....
Bionic is my first android phone.. I spent the months leading up to it reading up in case I decided to root. If I had any questions, I asked in the forums and got very helpful responses. Now I'm rooted, safely froze all the bloatware, and my phone works awesomely. Why is this such a hard model for some people to follow?
EDIT: To OP... not trying to be rude, just making a point. I do hope you're able to fix it with the processes everyone is suggesting, and do keep us updated on your results. Good luck!
