I just got a iPhone 3GS running on version 3.1.3. How can I update to 4.01 and then jailbreak? I tried to custom update via iTunes but keep on getting error message "3194." Any help will be appreciated. Thanks.
Are u using tiny umbrella? If so I'm guessing u must have blobs saved in cydia. After choosing the new firmware in the drop down box put iPhone in dfu mode and it should work. If not try another computer as there are problems with 64bit or it could be 32bit that has the issue can't remember now.
Yes, I have got old bootrom but whenever I tried to update via custom firmware 4.0, iTunes verify's the firmwire and gives me the error message "3194". Am I missing any step here that might resolve this issue?
