with odin all the info on my memory card is fine and will not be damaged right? Ive backed up everything, contacts, apps and such. Would backing up on my PC be a waist of time? 
Also, I don't need to uninstall superuser and do a data reset first do I? Was thinking Odin and following these directions was all I needed to do.
Thanks guys.
