I'm trying to restore a iPhone 3g I got that was jailbroken. I plugged it into itunes and hit restore and received the error 1015 that it could not be restored. I've tried using the tinyumbrella solution I believe I did it correctly but it did not work. Anyone have any suggestions?

Best Answer
You need to put it in DFU mode before restoring...
This can be done by:
Open iTunes and connect the iPhone to your Mac or PC.
Press and hold the Home button and the Sleep/Wake button at the same time. After exactly 10 seconds release the Sleep/Wake button. Continue holding the home button until you iTunes pops up a message telling you that it has detected an iPhone in recovery mode.
The iPhone screen will remain black.
NOTE***: It may take a few attempts to get your iPhone into DFU mode. Generally, I hold down both buttons then release the Home button just before I think the Apple logo would appear. If you are still holding both buttons down and you see the Apple logo you are holding them down for too long!
