Iphone 5 Stuck on "Waiting for Iphone"

Hello everyone, I restore my Iphone 5 on Itunes but after "Extracting Software"... it always stuck on "Waiting for Iphone" and in my Iphone screen i can see Apple logo with an empty bar at the bottom (not even moving)..

I tried to let it for a couple of hour but nothing happened.

I already tried to edit my host file by adding and removing:

#74.208.10.249 gs.apple.com

#127.0.0.1 gs.apple.com

#74.208.105.171 gs.apple.com

but its not even working...

and i cannot even enter Recovery Mode (with itunes logo and charging cord in the bottom)...

i did the combo thing like:

Pressing Power/Button simul for 10 sec. and release Power Button but continue Home button for another 10 sec. but nothing either..

Pressing Home Button for 3-5 sec and connect to PC with itunes, but no itunes logo and connector in my Iphone Screen (its just stays in DFU mode)... I even tried to trigger Silence Button...

So I was thinking it is an hardware or battery problem so I opened my Iphone and disconnect/reconnect my battery, but it doesn't solved my problem....

PLEASE HELP ME ITS JUST STRESSING ME OUT LOL :-(

Your reply will be much appreciated...

Thanks in advance...
