So I'm 4ever rooted currently. I really want this update. However when I search nothing happens, it just keeps searching. I've left it on for hours and nothing happens. I'm reading success stories about people who get the "Not Available" message and then do a FDR and immediately receive the update. I'm just curious as to if I can do one of these and if I'd retain root after? To unroot I'd basically have to do a complete reset anyways, so I'm wondering if I can just backup everything and go for it. Thoughts??
