Is this phone the same as the Fierce 2? My Model number is 5405N and it is running 5.1.1 Lollipop, the Metro PCS guy said it was brand new and they only received 2, It says it has a 16GB ROM, and was told it had 16GB storage, it only shows 11.22 for storage. I wanna root and install a custom recovery but have found no support, thinking about returning it tomorrow and getting the Galaxy Core Prime or The LG Leon. Any thoughts? It also has a battery he put in that is now unremovable.
