So my iPhone is 3.0, I have both 3.9 and 4.6 bootloaders, I have the iPhone 1,1 3.0 ipsw and I've used Redsn0w o.7.1, 0.7.2 and 0.8 and it all goes OK until after puting it in DFU. The white screen comes up, then shuts off and stays black screen and on the pc, redsnow says its Done. How can I unlock/jailbreak my iphone?? Also, I am on an unofficial carrier so my iPhone is in the lockscreen displaying slide for emergency and I cant get out... Can someone help me here??
