you don't have to replace battery or even take it out just take off back disconnect the battery(one screw) i don't know if you need to or not but i held home button down for 30 seconds to help fully reset the phone the push the silver connector back on and put phone together. now hold down home button and same time plug it in and keep holding home button until phone shows to plug in to iTunes o make sure iTunes is already open before plugging in. then do complete restore and you'll be back in business. trust me i tried for two days i thought i had a paper weight.
