I can't post a link yet cause I don't have the 10 post limit. But it's in the xda Verizon gs5 general section. Look for how to update to 5.0 and keep root.
I am running a rooted 5.0 deoxed rom that I found over at xda forums. I don't recommend doing this if you don't want to possibly damage you Phone. You need to get back to stock then find the 5.0 deoxed Rom then install that..
