ok here's the story, i had my 3gs on 3.1.2 and i had tethered jb using blackra1n. i saved my shsh files using cydia. last time i checked it said its saved on 3.1.3 i tried to restore to 3.1.2 and 3.1.3 cuz i wanted to jailbreak using spirit but neither worked. so i used spirit anyway and now its stuck in a loop. what should i do???
