    Hi,

    I own a iPhone 4 GSM Model A1332 with iOS 4.3.5. Jailbroken THETRED and Gevey SIM Ultra to unlock the carrier.
    Baseband: 04.10.1

    I want to upgrade to 5.1.1 (unthetred) but itunes gives a error every time!!!
    I created a costume IPSW on sn0wbreeze to prevent baseband update. (If i upgrade the baseband, Gevey SIM doesn't work)
    I try everything I read in Mac and in PC:

    Method 1:
    - Editing host file
    - Put iPhone in pwned DFU
    - Itunes - Shift+restore
    Error 3014 or "the iphone could not be restored its not eligible for requested build"

    Method 2:
    - Open tinyumbrella, start TSS server
    - Put iPhone in pwned DFU
    - Itunes - Shift+restore
    Iphone enters in recovery mode but... Error 11

    I try this operations various times with different variations both in MAC or WIN.

    The only thing i could do successfully was to restore the iOS (4.3.5) with redsn0w. It erase all data but now the iPhone it's not activated.

    I even try to install a older version of iTunes like a read in some posts but nothing work.

    Can someone please help me to upgrade iOS?

    Thanks

    You need SHSH blobs to upgrade to unsigned version of iOS. Use tiny umbrella to check if you have 5.1.1

    You can only restore to versions you have SHSH blobs for. Otherwise, you can only restore to signed version of iOS which is usually only the latest version. Currently, 7.0.3
