IPhone 3gs stuck in recovery?

I smashed the screen on my iPhone a couple of months ago and went to get it fixed today. The guy told me that I should just plug it into iTunes and it would be fine. I got home and plugged it almost five hours ago, but it still hasn't work. I've tried restoring it at least six times and putting it into DFU mode. I've downloaded Tiny Umbrella and iRecovery -- all Tiny Umbrella did was tell me that it was "giving up".

I've tried taking it out of recovery mode using redsn0w but that didn't help, either. I also tried jailbreaking it to get it out, but had no luck.

I downloaded different firmwares for iTunes but I just got the error code 3194. I tried 3 different tutorials to repair the error code, but none of them worked.

I called my service provider and was connected to the iPhone help, but all they did was tell me to restore it.

It's been five hours and I'm going insane. Does anyone know what else I can do?

Its been so long since I have restored my iPhone, now I have sony but I remember using sn0wbreeze and then using the firmware it created om iTunes, should be videos on YouTube about it sorry I couldnt help more

  • IPhone is stuck in recovery mode? ITunes said I needed to update, so I did. However, halfway through the update, it stopped, and my iphone went into 'recovery mode'.
