Opera Settings back to default?

[lifeuw19]

So I took the advice of someone on here and I messed up my Opera. My TP2 was displaying everything in mobile views. I wanted to change that. So someone on here said to change 2 things. Well... that messed up my browser, so I need to set it back to default. Shame on me for not writing them down. Can anyone help? I do NOT want to hard reset over this error... just need the default factory settings for the following.

Here's what I changed.
Under Opera:config
User Prefs
Changed Customer User-Agent to Mozilla/4.0 (Compatible; MSIE 6.0; Windows NT 6.0; en)
Don't remember what is was!

Cleared out UAProf URL... can't remember what it was.

These changes have messed up my entire browser. How can you change back to the default settings? I would think clicking on "default" right next to these entries would do it, but it does not. PLEASE HELP!

My version is 9.5, build 16983
