Getting an unknown error 9. Can't restore the OS.
Hi, I have a week 38 iPhone 3GS jailbroken by blackra1n. Pherhaps it's because I uninstalled a software not so properly. After that, it began the white apple loop. And every time I restored it, it gave the unknown error 9 out... whether in DFU or restore mode. I've changed USB ports, computers, Macs, systems... Same thing. Some are saying it's a hardware problem, probably the flash drive. Has anyone suffered this before? I appreciate for any of your help. Thanks a lot.
