Replaced my battery and now phone wont turn on
Hi, I recently performed a do-it-yourself iPhone battery replacement. After following all of the instructions and installing the new battery, I attempted to turn on the phone. Now while connected to a power source, all I get is a looping white screen with black Apple logo. When it is not connected to the power source, it is just a black screen. Is this a case where I messed up my phone or is it as simple as improper connections somewhere?
Thanks
