Thread: No Internet connection after downgrade

  1. #1
    Default No Internet connection after downgrade
    So I was able to downgrade my phone last night from 4.3.5 to 4.3.3 using Redsnow rc19. But after the jailbreak I have no internet connection. It has full bars and 3G but can't access any network apps or internet. I have already tried resetting network settings. But for some reason everything works on WIFI. Please help!!!

    Authorized carrier?
    If no? Ultrasn0w installed?

    Restore it again. 4.3.3 right over 4.3.3.

    It says carrier not available. No ultrasnow. My phone actually worked before the downgrade.

    Are you using an Apple authorized carrier SIM?

    OK good . You restored to 4.3.3 ... that implies you had previously saved 4.3.3 SHSH blobs. Yes?
    I suggest restoring to 4.3.3 again. Sometimes it does help.

    Do I need SHSH blobs to restore to 4.3.3 again?

    Yes.

    I'm curious and confused about your question ........
    .............. SHSH blobs were also needed the first time you restored to 4.3.3.

    Hmmm. I'm a bit confused .... but that's ok.

    Download and run Tiny Umbrella (link below), connect the phone, and press Save SHSH.
    In the General tab, what SHSH blobs do you have?

    Good, you have 4.3.3 SHSH blobs.

    To restore to 4.3.3. Run Tiny Umbrella, then start TSS Server.
    Go to iTunes, press and hold shift(pc) or option(mac) then click restore.
    Select 4.3.3 firmware from the new window.
    Wait for iTunes to finish.
    Done.
