iPhone 4 factory unlocked, not jailbroken, running iOs 5.0 suddenly turned off and can not be activated just died. -I pressed the power and home button together holding for 10 seconds but didnt work. -I connected to mac and tried to restore but got message Error 2001 and 2006 everytime. Restoration cannot be completed and screen of the phone goes white like a flash and turns off. -I updated iTunes (iTunes 10.6.3) -I updated operating system of the computer. (OsX 10.8 Mountain Lion) I even downloaded the latest updates of it. -I tried different USB cable. -I restarted the computer several times. -I tried to restore on a different computer (on PC) All didn't work and I am now desperate. Anyone who can help me to fix this problem? Waiting for your suggestions, thanks.
