Not turning on after battery replacement.

After replacing the battery and plugging the phone into the charger, it showed the Apple logo once, then just shut off and nothing more happens.

It doesn't get recognized by iTunes either.

I already checked the connections of all the ribbons.

I read some people saying to check the APN but the battery I received doesn't have the APN written on it anywhere. Old batter was APN: 616-0434
