Re Jailbreak and Unlock your iPhone with Baseband 06.15.00

Restoring your iPhone 3GS

With my computer I like to format it roughly twice a year. Sometimes you want to format your iPhone too. You know, restore it to it’s factory defaults. That’s a pretty easy thing to do with iTunes. But what if when you try to restore your jailbroken iphone with iTunes you receive the error 1015?

Fixing the iTunes Error 1015

There is a security feature within the iTunes restore procedure (towards the end of course :D ) that will check your basebase against allowed versions, and 06.15.00 is not an allowed version! Not yet anyway. At first it seemed that I would have to restore an older iOS 4.1 and then deal with that. But, with a little more research I found sn0wbreeze 2.2, a custom IPSW creator for 4.2.1.

Restoring Custom iOS 4.2.1 IPSW to iPhone

  1. You need to download the IPSW file for iOS 4.2.1, follow the link below to get the proper version for your iPhone
  2. If you didn’t follow the link above, then use the one below to grab the latest copy of sn0wbreeze
  3. Run sn0wbreeze and use the file you downloaded in step one
  4. You can use advanced mode if you like, but simple mode works great. Click simple mode :D
  5. Play PacMan!
This amazingly simple program does it all. If you’re stuck in the iPhone recovery loop problem, sn0wbreeze can help. The best news about this program is that it jailbreaks your iPhone with greenpois0n and allows you to unlock your iPhone using ultrasn0w.

Unlocking your iPhone with ultrasn0w

After you are done restoring your iPhone you will need to get online in order to unlock the iPhone. I just used my wireless connection as I need the unlock to use the 3G Internet.
  1. Open Cyndia (slide to the page on the right) and search for ultrasn0w
  2. Install
  3. Unlocked, too easy!

    Okay, Jim. . .I’m back to do some serious work on this iPhone 3g to prep for CR next month:

    But, I am going to need to fill in a few more details here

    -My current
    baseband set
    up with AT&T is 5.15.04 so I am assuming that I will be given an
    opportunity to choose the 6.15 baseband later. . .but. . .I am reading
    that once I put the phone on a 6.15 baseband there wlll be no going back
    and the phone will be a brick unless in CR. And that might be ok, as
    maybe can sell it there, but just would like to know upfront.

    -On Snowbreeze,
    one of the opening questions is whether this phone is going to be
    activated for use on an uncertified carrier. . .I am assuming that this
    choice is really asking whether we are wanting this phone unlocked. So
    am I saying yes here?

    -Well, I got the all green screen and it says ”
    if you have a green screen on your device you may restore to custom
    firmware”. And then it switched to Running iREB and the screen is still 
    on and green. I don’t know if something is actually happening or
    whether it is just hung up. . .?

    -Well tried that 3 times and can never find Cydia on the phone yet so assumed that it is not working. Am now trying Redsnow to see if I can break thru that way. . .

    Lastly, we spoke briefly about
    jailbreaking a 4S and i, like you, understand the risk if something goes
    down as that will void the warrantee on this 2 month old phone.

    Anyway. . . have you heard anymore about the success of this with new phones?

    Have a very Merry Christmas,terry s

      Hola Terry,

      For your 3G
      - Basically you will need to run the latest RedSn0w tool and make sure to use the 4.2.1 OS. During the update using RS you will be optioned to update your baseband. Once that’s done you will find Cyndia

      For your 4;
      – http://www.iphonehacks.com/2011/12/untethered-ios-5-0-1-jailbreak-for-iphone-4-iphone-3gs-ipad-1-ipod-touch-4g-ipod-touch-3g-released.html
      – Just follow the instructions on this page to unlock your iPhone.

      Whenever you jailbreak your phone (and unlock) you will have voided your phones warranty, so that’s not the issue. The issue is when you change the baseband, because when you do this you cannon restore the OS to a factory image.

      I hope that makes sense, if not email me and we can schedule a call.
