Re: Help upgrade my iphone
Not much into jailbreaking myself, but an iTunes error 3194 means that your device is "not eligible" for the requested iOS build... so do you have the SHSH blobs saved for this version? If Apple is no longer signing that version and you donít have the SHSH blobs saved, I donít think you can get there from where you are.
