The “White Apple Logo Screen of Death” is a term that has been coined by iPhone users to refer to the problem that is usually encountered during an application installation or update of the IPhone.
During application installation or software update, something interrupts the iPhone and/or iTunes from finishing the task. The iPhone then suddenly reboots making the screen go dark. During the reboot, the goes dark, comes back and Apple Logo is displayed.
Suddenly, the iPhone boots and it’s file system mounts-noted by two short vibrations, beeps or both. However, this is the farthest the iPhone boots. It never boots past the Apple Logo.
Most users have been encountering these problems and returning their iPhones to Apple stores claiming that the phones are “bricked.” However, replacement phones have also shown the same problems. It seems that’s a general bug with the iPhones.
If you encounter such problems with your iPhone during install or update from iTunes, you have to perform a complete restore on the iPhone. Unfortunately, this is the only way you can go about it.
This process can take hours because of enormously lengthy backup and sync times. In such a case, the iPhone is not “bricked” but only stuck in some kind of endless loop. This loop can be broken by doing a factory restore of the iPhone.
To do a factory restore, you press and hold the Sleep/Wake and Home simultaneously until the iPhone resets. You have to wait until the Apple logo appears then you release Sleep/Wake button. It’s also advised not to release the Home until you see the prompt to connect the iPhone to iTunes.
When prompted to select parts to restore, restore the iPhone’s firmware, all your settings, all your media, and all your Applications.
