So today I tried updating to iOS 6.1. I have an iPhone 4s. I could not update with iTunes because it kept on saying the device isn't eligible for the requested build. I went to restore and update through iTunes and now it is in a recovery loop and I cannot get it into DFU mode. I also can't just restore with iTunes because the "device is not eligible" keeps popping up. I would greatly appreciate any and all help. Thanks.
