Unlock iOS 6.0.1 on iPhone 3GS, 4 using UltraSn0w Fixer

Unlock iOS 6.0.1 on iPhone 3GS, 4 using UltraSn0w Fixer – Apple just released iOS 6.0.1 with minor bug fixes. Although not a major update as it included no new features, but still you would want to download it if you want to be kept updated and want a better iOS.

    Hy, it still not working on my 3GS, during instalation give me error: /user/bin/dpkg returned an error code (1) — please, have anyone same problem?


  2. ZK says:

    You need to jailbreak again and this time select the “Downgrade from Ipad Baseband” option in redsnow. After the jailbreak, boot tethered using redsnow and you would get service.
    Redsnow is not working on 3gs baseband 6.15.00 (Ipad baseband). Downgrading it would fix yout issue

  3. david says:

    thank you:) now, it’s ok and my iPhone is unlocked:) I had baseband 6.15.00 on iOS 6.0 and unlock was ok. So i thought, that ultrasn0w and this fixer is the same for baseband 6.15.00 and doesn’t mater on i0S.

    I have BB 05.15.07 ios 6.0.1 JB OK with snowbreeze … what can I do to unlock it? just wait for new version of ultrasnow ? (JB with redsnow didnt work and I dont have shsh blobs to downgrade)

  18. jose says:

    You have installed ipad baseband, now you need to the same again but chose downgrade baseband, then you instal ultrasnow, ultrasnow fixer, reeboot using redsnow and voilá:)

  19. jose says:


  20. jose says:

    and always select IPSW IOS 6.0, not 6.0.1.

  21. jose says:

    its because you are choosing the ios 6.0.1 hat doesn’t work at redsnow 0.9.15b3. you nedd to choose ios 6.0, it will work with you ios version 6.0.1

  22. jose says:

    Select ipsw ios6.0

  23. jose says:

    You have installed ipad baseband, now you need to the same again but chose downgrade baseband, then you instal ultrasnow, ultrasnow fixer, reeboot using redsnow and voilá:)

    always select IPSW IOS 6.0, not 6.0.1.

    Use last version of redsnow

  24. sean says:

    Uninstall Ultrasn0w. Run Ultrasn0w fixer for ios 6.x Now install ultrasn0w. Worked OK for me

    1. Restore to ‘iPhone2,1_6.0.1_10A523_Restore’ using iTune 10.7
    2. Choosing the ‘iPhone2,1_6.0_10A403_Restore’ IPSW, jailbreak using ‘redsn0w_win_0.9.15b3′.
    3. Again using ‘iPhone2,1_6.0_10A403_Restore’ did just boot tethered.

    No error with above steps, but didn’t get service.

    Then based on the suggestion, I tired:

    4. Installed Ultrasn0w Fixer.

    Still no luck, then tried:

    4. Jailbreak again to Downgrade to iPad Baseband.
    5. Using ‘iPhone2,1_6.0_10A403_Restore’ did just boot tethered.
    6. Re-install Ultrasn0w Fixer.

  44. brandy says:

    I’ve tried and it is not working. I have a 3gs, ios6.0.1, baseband 05.16.07.
    I am jailbroken, nut I updated and can’t get my StraightTalk SIM to work anymore.

  45. Rik says:

    Google ‘hackivate ios 6.0′

  46. Rik says:

    5.16.07 is not one of the supported basebands. The list is above.

  47. Rik says:

    If the wifi is greyed out, and the bluetooth, and the baseband doesn’t display, you have fried the BB chip. If it’s only the wifi, it may be another issue.

  48. Bijan says:

  51. V-milptas says:

    Respond to mesum: Did you use Cydia to jailbreak (unclock) your iphone before you upgraded to iOS 6.0.1 using iTunes? I had same problem as you do. Was crazy about this. And I had to pay a guy to fix my phone back to iOS 4.3 ($20 for the service). Then, I checked my iphone, noted that the Cydia icon is back. It seems like he used Cydia to un-do. Anyway, I am using my iphone as a backup, and view my son as a babycam viewer.
    Good luck.
