Wanna know if my phones bricked or not :/

I bought an n7000 when it was first out and haven't used it for about 2 years now ever since it once got into a bootloop(freaked out back then). I got my hands on the phone today and I had the battery taken out when I stopped using it. It wasn't switching on or charging. Do I have to replace the battery? What's wrong with my phone? Can't figure it out :/
