I tried to restore iphone 3g via itunes but almost at the very end 1015 error window pops out. Tried ireb, tinyumbrella, recboot but it didn't solved the problem.

A guy a work had this problem. We searched a lot and found it was an issue with his anti virus software. Turned it off, and it updated just fine.

I turned off anti virus and updated with custom firmware and it worked.
