iPhone 6s Out of Box Problems

Hi guyz,

Im living in Pakistan so I dont have apple genius services here.

I bought new iPhone 6s 64GB space grey color.

It had out of the box problems like it didn't start properly and showed screen glitches while starting on apple logo and it is on bootloop. I tried restoring with itunes but with no luck. When I try to restore via iTunes, iPhone automatically shows screen glitches and then shuts down as shown in video. Need help.
