IPhone is stuck on iPhone must connect to iTunes?

Okay, so I got an iPhone but it still had information on it, so I went to Settings > General > Reset Media and Settings, or something like that.So, at first it loaded, but it was really slow, so I decided to power turn off by pressing the power and home button, turned it on, and then the iPhone must connect to iTunes. So I connected it to iTunes and it said that I must restore the iPhone before I can do anything, so I did restore it via iTunes. After it went through all the loading, it said an error has occurred. So I went online for help and the only idea popped up was that I need to turn it off via home and power button, turn it on, and as soon as it turns on, I plug it in. That didn't work. I need ideas! Please help. I don't want to take it to the Apple store cause it's really far away, so don't even suggest that.

Jailbroken iPhone 4 will not restore in DFU mode?

I've tried to restore my iPhone 4 on iTunes multiple ways. The first time I tried restoring it I just plugged my phone into iTunes and went to devices and clicked restore under my phone… Didn't work. I researched a little and found out how to put your phone in DFU mode or recovery mode (whatever it is) and tried restoring it then… Didn't work. I always get the same error message saying "The iPhone 'black iphone' could not be restored. An unknown error occurred (3194)". I want to update my phone to iOS 6 and to do so I have to restore it first to take the jailbreak off. I have also tried resetting my phone under settings on the iPhone and that didn't work either.
