Try as I might, I can't seem to find any Odin or other file that will allow me either to root my phone directly, or downgrade it to KitKat, which would make it easier to find such a file. So far, I've been well satisfied by Lollipop and would ultimately like to flash a Lollipop based custom ROM. There seem to be available downloads that will allow you to do that in one step, but they only work if your current OS <> 5.0. If you have 4.4.x your covered, and if you have 5.1 you're golden. But with 5.0 you're SOL, unless you have the release build. If you've installed the Stagefright patch and have build version LRX21T. G900PVPU3BOG1, you can't use this.
Meanwhile, I've tried several of the Sprint S5 KitKat downgrade files at sammobile, but after three failed tries, I'm not sure it's worth the bother of another five-hour download.
So how else can I get downgraded or rooted? I wouldn't mind just keeping the phone as it is, but not being able to use Titanium Backup is inconvenient, to put it nicely.
