iPhone doesn't turn on
I just got an iPhone 5S with a broken screen and home button/front camera missing. I tried turning it on but there's no reaction at all (no sound etc.). I tried removing and reinstalling the battery but it's not working. The battery only had a voltage of about 2.5v, so I ordered a new one but it's still not working. Is the logic board broken or am I doing something wrong?
Is this a good question?
