redsn0w 0.9.6beta5 Download to Unlock iPhone 3G/3GS

Update 1: If you’re on iOS 4.2.1, and inject the 06.15 iPad baseband, you won’t be able to restore to stock firmware, or downgrade your baseband to 05.xx.

Explained by the Dev Team:

WARNING — YOU DO THIS AT YOUR OWN RISK!  PLEASE UNDERSTAND THE CONSEQUENCES OF UPDATING TO 06.15.

  1. There is no way to come back down from 06.15, and there’s no hiding the baseband version from Apple. You’ll be voiding your warranty in a very obvious way.
  2. If some future baseband comes out with a critical fix, you won’t be able to update to it if it remains down in the 05.xx sequence (then again, you wouldn’t update to it if you wanted to keep your unlock anyway).
  3. Starting with FW 4.2.1 if you have 06.15 on your iPhone you won’t ever be able to restore to stock firmware (it will fail).  You’ll need to only restore to custom IPSWs (then again, if you’re unlocker you should already be doing that).

Certainly don’t update to 06.15 if you don’t need to! Only do this if you need the unlock and you’re stuck on 05.14 or 05.15, and you’re willing to assume the above risks.

redsn0w 0.9.6beta5 is now available for download for OS X and Windows users. This updated version’s primary purpose is to inject the unlockable iPad baseband into iPhone 3G/3GS units, to be unlocked via ultrasn0w for iOS 4.2.1.

Here was the update posted by the iPhone Dev Team:

Update #2: The new redsn0w 0.9.6beta5 is out.  It gives both Windows and OSX users the ability to flash the iPad 06.15 baseband on iPhone3G or iPhone3GS.  It fetches the baseband files directly from Apple for now (the only IPSW you ever point it at is the stock IPSW for the FW on your iPhone right now).  There may be a long delay while it’s doing this (their servers are currently getting pounded).

  • OSX (SHA1 a322ec2c9e91993eca21abaf2e655bb44de3d7d4)
  • Windows (SHA1 7250416e17c3aea9838cdfc73712b38b025e2ed0) (Windows 7 and Vista users, please run redsn0w in “XP Compatiblity Mode”)

If you do flash your baseband via redsn0w, please keep it plugged into USB the whole time.  You don’t want your battery to die during the flash process!

Let us know how redsn0w works out for you. As always, follow the above procedures at your own risk.

    Be aware that if you have firmware 4.2.1, once you have updated to 06.15 baseband, you cannot restore stock firmware to your iPhone. You will only be able to use custom firmware.
    In addition, there is no way going back to 05.xx baseband either.

    Question Gary….

    If I am still on 05.11.07 (ios 4.1) and DO NOT inject the iPad BB using Redsn0w, what will my BB be when the JB is done? Redsn0w used to say that they will not change your BB. Will it be an unlockable BB or still on 05.11.07?

    Thanks…

  • Tomsiphone

    Sorry…the JB would be on 4.2.1. Guess that helps :)

  • Derka181

    same thing is happening to me. HELP

  • Derka181

    wow tried jailbreak so i could unlock it. it says” waiting for reboot” when it is DFU mode. wont go any further. any suggestions?

  • http://www.iphoneincanada.ca Gary

    Do a forced reset, and try again.

  • http://www.iphoneincanada.ca Gary

    The latest version of redsn0w will inject the iPad BB. If not, then you’ll just be jailbroken.

  • http://www.iphoneincanada.ca Gary

    Just try the process again, do a forced reset.

  • Tomsiphone

    Okay, got that. I am thinking that since I would be updating from a stock Apple file (as the new guide instructs) the baseband would also be updated…. before Redsn0w is used.

    What I would like to know is what new baseband would be on the phone after that upgrade?

  • Time

    It says” waiting for reboot”?????

  • Snoopdogg

    This site does not give enough info on how to jailbreak/ unlock. The site needs more details on how to unlock. The info is to Vagus.

    Use pwnage(custom ipsw) to update to 4.2.1 while preserving your 5.11.01 BB.Then install ultrasn0w 1.2 to unlock. I’m not going to mess around with 6.1.5 BB on an iPhone and prefer to wait for an unlock for 5.XX.X.

    Before it was released there were a number of sources claiming that this unlock was suppose to work with all base bands, therefore I’m going to wait for them to clean up this mess and find a better solution before updating my BB past 5.11.07. I have another phone on 4.2.1/5.15.04 and that’s where it will stay until then.

  • daniel

    Sorry meant 5.11.07*….It’s what I’ve done…. 3g/4.2.1/5.11.07 BB/ultrasn0w 1.2

    I have a serious problem. Originally my 3GS is at firmware 3.13, baseband 5.11, then I used Redsn0w 0.9.6b5 to jailbreak. I downloade iPhone2,1_4.2.1_8C148a (3GS IOS4_2_1).ipsw and used iTunes first to restore it. After restore I noticed my iPhone baseband already changed from 5.11 to 5.15. Then I proceeded using Redsn0w to jailbreak it (Just “Install” option, say “NO” to newer model, and did not click on “Install iPad baseband”). After jailbreak I ran Ultrasnow from Cydia.
    The issue now is I never see any carrier signal on the upper left corner of screen.

    Help, what should I do? My 3GS is now became an iTouch.

    Any advise to proceed from here? Can I restore from my backup to go back to firmware 4.0 and baseband 5.11?
