Samsung Galaxy Note retail 2

Product Name: Samsung Galaxy Note retail 2
This is a Samsung Galaxy note 2. Always with a screen retail protector and a Outter case that is very sturdy. Will come with brand new 8 screen protectors most of which are mirror screens. Will come with an additional battery. A battery charger. 2 USB cables and a plug. Also will include a wallet case. I had this for a while but all of a sudden it stopped working on me. Even if I try to reboot the system it just turns on with the Samsung logo (see pictures) It was unlocked and I was able to make calls with it as well. It never dropped or went into water. So I'm guessing it was something to do with the system itself. I'm selling this phone for parts or if anyone knows how to fix it! once it turns on it can't turn off unless I take out the battery. selling AS IS no returns accepted. Any questions please ask :).
