White screen of death iPhone 3GS 16gb
My iPhone 3GS displayed the White screen of death and was told to restore my phone but iTunes said there was a problem and now my iPhone won't turn on at all.
iPhone 3GS, iOS 5.1.1
That happened to me once and the only was is to fix it is to use recovery mode.
1. Connect your USB cable to your computer but NOT your iPhone.
2. Turn your phone off.
3. When your phone is off, press the home button and connect your iPhone to your computer.
4. Your iPhone will turn on and keep pressing to the home button. iTunes logo will appear on your screen.
5. You can start your restoration progress.
Hope this helps. Thats is how I saved my phone. It also seems to me that the phone you are using right now may had been jailbroken and stopped working.
