Unable to switch on
When i switch on the iPhone 4S i get the symbol of itunes in the middle of the display and charging cable symbol at the bottom of the display. And when i try to restore it or update it happens to be completed upto 75% and it says error 29. Which is obstructing me to use my old sentiment. I used itunes in different laptops and switched many charging cables as well but couldn't restore or update it. Can you guys please help me if anyone here is aware of the problem above mentioned?
iPhone 4s, iOS 8
