Unknown password, broken home button on iphone 3g?

Ok my friend forgot his password for his iPhone and he asked me if i could restore it. I found out that the home button was broken so i can't put it into dfu mode! I have tried recboot but no luck. The phone says connect to iTunes because of failed password attempts.iTunes doesn't let me connect the phone and says i need to enter the phones password? Please help

Added (1). He never synced with itunes and didn't have findmyiphone

It's going to need to be hooked up on the computer it's mainly used at's location. It can't be restored because iTunes is basically saying the phone is stolen if you don't know the code and are trying to restore it.

  • Unknown iPhone passcode set by unknown person? A passcode has been set on my iPhone without me knowing, now it is locked up. It says here to connect it to my computer and back up then restore my iPhone. Will this clear everything off my phone or will it be the same as it was before it got locked? I have only attempted unlocking it about 5 times in fear of disabling it. I do not want to back up then restore it if it will clear everything off and transfer it to the computer. Are there any alternatives to unlocking my iPhone?

  • Lock and home button broken on Iphone 4? My lock and home button are broken… Usually i've been able to manage with assistive touch and making it so it won't lock automatically, but recently i had to restore it. When i did, i went to my photos first to check to see if I still had any, but now I realize I don't have assistive touch yet and i'm stuck at my photos. How do i get out?
