Hello everyone. My friend gave me a four-five year old modded (ORIGINAL, not 360) Xbox, and I've been gaming on it for along time. But now things seem laggy, There's alot of music and Files I want to delete from there, plus I feel it would run faster if I A.) Deleted Avalaunch altogether and only used XBMC, or B.) Uninstall and Reinstall Avalaunch or XBMC. I'm very worried on messing up this treasure, because I have no idea if its softmodded, has a Mod chip or not, If there's an uninstaller anywhere, etc. I want to do it the safe way, I just want rid of all the garbage that the old user put on it and have it set up with MY music, MY pictures, and stuff like that. Can anyone help me? I've researched online and I'm not finding much. I'm willing to do any steps necessary, I just want to be smart about it, I've never modded before. My Xbox has like.. 4-5 hard drives? Already has everything working on it, I want want a fresh restart . Help please?
