Hello,I just repaired my iphone 7,i changed the battery,i was extra careful with the display,i plugged everything in correctly. I turned the phone on and it was stuck on the apple logo. I tried unplugging the front camera but it was useless.I am scared that i broke my phone,it’s not the first time i repair an iphone but it s the first time this happened to me.Please help
Have you tried with the old battery? Could just be a bad battery you recieved from whatever supplier you got it from.
