How to Restore a Bricked iPhone
A "bricked" iPhone is one with a black screen that can't be used for calls, apps or even turned off. You might be spooked at first to see the black screen, but restoring a bricked phone is easy enough. Just be advised that the full recovery time can be a couple of hours, depending on the amount of apps and other features added since the last full backup of the system.
Things You'll Need
- Computer with iTunes
- Connector cable
Plug the iPhone into a computer with iTunes, preferably the computer normally used to update the phone.
Reset the iPhone by holding down the home button on the front as well as the power button at the top. The phone will go through the normal reset.
Continue holding down both buttons. The phone will restart.
Continue holding down both buttons until the iPhone displays the iTunes logo and a USB connection symbol. At this restore screen, release both buttons.
Use iTunes to restore the phone's last full backup. After this, you might need to upload any apps or features that were added to the phone since the last backup.
