Replaced iPhone 4 battery and no sound.
Hello, I bought my battery from ifixtit. I installed my battery. My phone has life but there is no sound. I cannot call. I cannot check voice mail, and I cannot listen to music. I've tried playing the speaker, using my bluetooth, and using headphones. I have no sound.
What did I do wrong? I followed the instructions on the ifixit Youtube video. Please help.
Is this a good question?
