How can I restore my iPhone 4S with a broken lock button and with a passcode

I have tried restoring the phone by trying to let the battery drain and by plugging it in and holding the home button but that did not work. I also tried using RecBoot but kept getting an error message. The iPhone has a passcode and a broken sleep/wake button so I cannot put it into recovery mode. The holding of the home button method was given to me by Apple (called them). It is running iOS 5.1.1 if it makes any difference. Please help!!
