hi i have a friends 16 gig 3gs on atnt that is stuck in restore mode after an attempted jailbreak using limera1n. i believe his phone was on an old firmware version when he tried it. it stall while in dfu mode and he eventually unhooked it from the computer. i have tried ireb r4 to no avail. when the device is connected to itunes it shows the phone and serial number but says n/a in the software and capacity fields. any help would be greatly appreciated. thank you
