Q: i keep recieving an error code (-1) cannot restore iphone message what can i do?

Try to restore 2 more times. If get the same error message,

take the iPhone to the nearest Apple store for a free evaluation.

Once the diagnosis is complete, the staff will explain your options.

-1 is error code for hardware failure. Assuming no damage to

your iPhone and it is not jailbroken, you may be eligible for a reduced

price Out of Warranty replacement.
