1. turn off the iphone
2. hold down the home button and the power button at the same time..
** what i do is push the home 1st then the power.. the other way may start up the phone which we do not want..
3. you must hold these buttons for 10-12 sec depending on your counting speed (do not count too fast or too slow if your fast it wont work if your slow the apple sing will pop up)
4. as soon as you finish counting leave the power button and keep holding the home button.. ( you must hold it until you see your itunes accessing net on the mac)
5. if your phone has a black blank screen then your in DFU MODE
6. if this doesn't work the 1st time just keep trying sometimes it takes a few tries..:)
