Iphone 4s stuck in restore mode

I seem to have a slightly different problem than the usual iphone stuck in restore mode. I got this phone from someone else so I don't have the exact details but it looks like the original problem happened when updating to 7.1.2. When the phone rebooted it got (and still is) stuck at the restore screen. After some more troubleshooting, I was told it looks like the baseband firmware is causing the problem. The restore fails right at the very end. The error in iTunes is unknown error 1. Any ideas on how to get the phone working again? I've put it into DFU mode and tried to restore different versions and nothing seems to work. It ends up with the same error at the end. I don't care about saving any data either. Thanks for any help.
