    Hi, does this jailbreak have the option to change the baseband 06.15.00? I have a 3GS on 4.3 (8F190) and 05.16.01 and want to unlock it. If not, what is the best route forward to unlock the phone?

    Thanks

    •  
      Pramod5 years ago

      Use the latest iteration of Redsn0w instead only for the iPad BB update (tick only this option). You can JB your device via JBMe after that.

  •  
    jdubu5 years, 1 month ago

    Go to settings, then click store, then it will say sign in.. put in your email & password if you created one already and it should work. I had the same problem and came across your post so I thought it might help even though its a little late!

      3194 suggests that your trying to restore to an iOS version for which you do not have an SHSH saved for. Have you saved the SHSH for the iOS version your trying to restore to? Also please fill me in with your iPhone iOS/BB version details as well.

    from host what else should i do to find gs.apple.com.please show me

    •  
      Pramod5 years, 6 months ago

      Nothing, just make sure that the line doesn’t exist at all. if it does, delete it from the hosts file and try the restore once again. If it still doesn’t work, I suggest you to try the restore on a different computer/your friends computer. It should work positively if everything else fails. :)

    I got problems when I did as you suggest! I have sucessfully upadte to ipad baseband 06.15.00 from 05.16.01, but now when I tried to jailbreak, still got a lot of problem! and then my iphone was stucked in recovery mode, no matter how hard I tried, I can not quit the recovery mode! Even, I can not restore to current ios 4.3.1 because it keeps telling me error 1015: I am trying to downgrad. So I am in big trouble now, can anyone help me out? Appreciated!!!

    •  
      Wolverine5 years, 8 months ago

      Nothing is wrong. You must be restoring stock IPSW thats why your iPhone got stuck in recovery mode. Also when you get 1015 error, you can use Recboot or TinyUmbrella to kick it out of recovery loop error. Make sure to restore custom iOS 4.3.1 or iOS 4.2.1 (SHSH blobs needed) IPSW instead of restoring stock IPSWs. Remember, once you are on iPad baseband, you can never restore stock IPSWs.

      •  
        john5 years, 8 months ago

        Thank you very much, Wolverine. I have error 1015 prbably because I use stock IPSWs when restore to 4.3.1, as you say. En, I will try to restore with custom 4.3.1, itunes always give me error 21 or 1065 when I restore without the store IPSWs.
        I am trying now, thank you again!

          •  
            Wolverine5 years, 8 months ago

            There is no such baseband like 05.15.00. I think you mean 06.15.00. If that is the case, Yep, PushFix Ultrasn0w Fixer will do the work!

            For the time being, lets get your iPhone 4 back alive. Don’t mind about ultrsn0w/JB now. So do as I say.

            1. Download the latest 4.3.3 iOS for your iPhone 4 from here http://bit.ly/kjLNRn.
            2. Open iTunes & whilst still making sure your iPhone is connected to your computer, Hold “Shift+(Click)Restore” button in iTunes. It’ll now pop up a browse window. Point it to the IPSW you downloaded just now from the above step and wait for it to finish.
            3. Wait for it to finish. If all goes well, you’ll be back up and running your iPhone as good as new.
            4. If you don’t have the official carrier SIM to which it was locked to, don’t worry about it now.

            Follow the steps above and let me know how it goes. Good Luck. :)

            What does your hosts file read? Does it have an entry for gs.apple.com in it? If you are using Windows, your hosts file is most probably c:\windows\system32\drivers\etc\hosts. If you have it, remove the same and try the same procedure once again.
