Hi there, I am quite new to this forum..I am on the verge of giving up because I have been trying for days and all I have only been given false hopes of ever getting my iphone updated. I am also quite new to this entire procedure of updating this iphone. So, to begin with, I am trying to update my iphone 3gs (unlocked and jailbroken) because none of the apps are compatible with my current version 4.0. The modem firmware is 05.13.04. I have tried following many tutorials on how to update the iphone. I have used programs such as the latest version of RedSn0w and Sn0wbreeze together with itunes. itunes is another problem by itself. I keep getting error codes such as 3194, 1600, 1601, 32, 11 to a point I don't want to use itunes unless absolutely necessary. I tried to either stitch the ShSH blobs to the ipsw to create a custom ipsw but redsn0w crashes and stops working. If I try a simple restore ipsw option it tells me exploit fail and I have quit the program. I just want to update this phone preserving the baseband, so I don't lose the unlock and jailbreak features. Is there some method I am missing? I tried updating to either ios 5.1.1 or 6.0 but neither is working. I am at a loss. Any help is appreciated. Thanks.
