I forgot my iphone 6 passcode
I have forgotten my iphone 6 passcode and I have tried to restore the phone in both iTunes and icloud. The problem is that I never connected it with icloud or iTunes. Every time I try to restore it on iTunes it either tells me I need to enter the passcode (which I don't know) or it says that the disc is full. Im not sure what it means when it says that. This is a new phone I received for work and I don't use the phone on weekends so when I turned it on today it asked for my passcode which I have forgotten. Please help!
iPhone 6, iOS 8.2
