I recently found a iPhone 3GS. (yes found it on the road near a park. NOT STOLEN. I wanted to find the owner but it appears to be jacked up somehow) It has a all black screen but is detected by itunes. iTunes shows it in recovery mode and says that it must be restored. I decided to go ahead with this process but i get either a error 3194 or 21 or 1600. I have done all the button much options. The only thing that it does is disconnect and reconnect the devise from my computer. I get NO icon or anything else of that nature. The only time I get anything on the screen is either at the end of using itunes to restore it will sometimes(not all of the time) turn on white, but then I get the error. I have tried using tiny umbrella, snowbreeze, redsnow, ireb and blackrain. all of which have not worked. I can get the tinyumbrella recovery fix to get lots of commands to flash across the screen of the iPhone but it always comes down to a error stating either user systemfile wont load or something else where it says "giving up". I have about 8 different firmwares. I have tried them all and yes I used shift+click restore to try and use those. If anyone has any new information that they think would work I would really appreciate it. I know it seems like a similar problem and i should be able to just look this up but the combination of problems i am getting is unlike anyone else.
