Install G900FXXU1POBK EE Galaxy S5 Official 5.0 Lollipop Stock ROM

Stock ROM G900FXXU1POBK an Official 5.0 Lollipop Update on EE’s network Galaxy S5 on in United Kingdom. The latter’s build number has a quite  strangely different label and it can tell that there is something special added onto it which is not commonly available compare to those previous Lollipop updates like the BOB7 and the BNL9.  But then again, noting that the G900FXXU1POBK is carrier branded firmware build and is exclusive with the said network.

Since this stock ROM has been around few days earlier, so I have a little bit time to check it for myself since I have been skeptical on a carrier branded firmware. And out my own findings within 3 days, I can tell that this is a stable Lollipop firmware build compared to G900FXXU1BOB7 which is less of issues like FC’s and battery draining problem. But don’t marked my word on it, just try it. So if you got a Galaxy S5 and but you may restore back to purely stock right now then grab the stock G900FXXU1POBK below.
