3GS jailbroken with Spirit 3.1.3 locked up, can't restore
I jailbroke this phone for the first time last month when Spirit was released and had no problems. Then, last night, Cydia told me it had a bunch of updates to install so I installed them. It looked like everything was going fine, then it got stuck when I selected to restart the springboard. I was forced to turn it off by holding power/home buttons. Now, I can get the phone into Recovery mode, but I am unable to restore through iTunes.
I've been searching around trying to figure this one out, with no luck. I have downloaded the 3.1.3 custom IPSW files, as well as trying a few of my old backups, but I get an error message each time either being incompatible, or not eligible, etc. I can run again and repost the exact errors if needed.
I just yesterday had uploaded my SHSH to Saurik's server through Cydia, if that makes a difference at all.
At this point, I'm not concerned with being able to re-jailbreak necessarily, I just want to get the phone back to being operational with any firmware. I will then likely upgrade to regular iOS 4.0.
I am currently on iTunes 18.104.22.168. Any suggestions on how to get this paper weight operational again?
