I just replaced my iPhone battery with an iFixIt replacement battery. Now the screen is flashing on and off with the apple logo. Any idea on how to fix? I tried plugging the phone into my laptop, but iTunes is not showing the device.
The battery was probably shipped with a very low charge, I believe there is some regulation regarding this. Connect your phone to an original Apple or MFi charging brick for a few hours to see if the battery charges properly and then try booting your phone again. If that doesn’t work, then double check your work. If it still doesn’t work, then contact iFixit Support.
