There are many reasons to get an error 1015 in iTunes when trying to restore an iPhone. However, given that this is an iPad forum, I'm afraid we really can't help here.
May I suggest you try asking this question over at our sister site at www.iphoneforums.com. When you do ask the question, please give them more information, such as what type of phone you are trying to restore, what firmware version you've got installed and what your baseband is. Given all that info, I am sure there is someone over there who can help.
