Hey everyone, my friends iphone 3gs was just recently jailbroken so then he installed winterboard which required a restart and after that you know how it goes. Tethered -> rejailbreaking -> solved but no this case blackra1n wouldnt boot. After running blackra1n and everything shows normally like geo's face and all then it just shuts off. Other problems are its stuck in 3.1.2 connect to itunes screen and when i tried to shift restore it wouldnt let me do 3.1.2 because the device is not eligible. Pretty sure that means they dont want me to use that firmware. So the choices im left with now is restoring to 3.1.3 which means im screwed if i do so. What can i do?
