I used WUG's to root, installed 4.04 and everything worked fine. However, after installing Titanium Backup it says "I could not aquire root priviledges. This app will not work. Please verify that your ROM is rooted and includes BusyBox and try again. Is it because 4.04? Now that I'm on 4.04, can I install any custom roms? I really don't understand the difference between being on 4.04 and the ROMS themselves. Do they replace the entire OS? Or are they more like "themes"? Thanks again!!!
