iPhone 4S, Forever recover mode?
According to Apple, error 1 means: 


  These errors mean that your device or computer may have a hardware issue that's preventing the update or restore from completing.


I would suggest you try:


Other usb ports
Not using a usb hub, plug directly to your machine
Different computer
Different (preferably original) usb cable
Use TinyUmbrella and its "exit recovery" option (you probably need to put your device in DFU mode first)


Also make sure you use the latest version of iTunes



Finally, if everything else fails, then it could be an actual hardware issue according to reports from other users :/
