My phone wont boot up?

So i installed chainfire 3d then i tried to install the drivers as said in the app but after that my phone wont boot up anymore... I tried wiping all data and cache through recovery mode so i guess now i dont have root anymore but i just remembered that i deleted the default launcher of the phone
-___- my phone is Polaroid PROG400 4.1.1 Jellybean.

(new to da forums by the way)
