Iphone 3g 3.1.3 doesn´t boot
i´m really in trouble. I jailbreaked my friends Iphone which is on 3.1.3 using redsn0w 0.9.4 with 3.1.2 and everything worked like the tutorials said. After that I installed blacksn0w via Cydia but the device hung up. Now when i start it display the Recovery Image. So i tried to restore with original 3.1.3 and 3.1.2 in recovery and dfü mode but at approx. 35% itunes prompts error 9.
I would really appreciate if someone could help me and sorry for my bad english.
