  • sn0wbreeze Jailbreaks iPhone OS 3.1.3 : blacksn0w & ultrasn0w Can Still Unlock


    UPDATE 3: iH8sn0w has fixed sn0wbreeze with its update to v1.4. The program is now compatible with old bootrom iPhone 3GS read our guide for more info and download links:
    http://modmyi.com/guides/how-jailbre...reeze-windows/


    UPDATE 2: iH8sn0w has removed his sn0wbreeze download until it is fixed for the iPhone 3GS. We'll update again when a fixed version is released . . .

    Cash UPDATE: I'm telling you now, don't bother with this right now. #1 3.1.3 isn't worth it. #2 sn0wbreeze isn't as finished as it should have been before they released it. Many of you will ignore our advice and do wtvr anyways so I WILL get a guide up, if I find a trick to making sn0wbreeze work! If I do make a guide, it WILL NOT be for the iPhone 3GS, after many repeated tries with different .ipsw files made with sn0wbreeze I am fairly convinced that sn0wbreeze is not compatible with 3GS 3.1.3 firmware.


    Well folks, that didn't take long at all. We now have the ability to jailbreak and unlock the iPhone on the new OS 3.1.3 only days after it's release. We have two options for different basebands, 04.26.08 and 05.11.07.

    Sn0wbreeze 3.1.3 can jailbreak iPhone 2G, 3G and iPhone 3GS (old bootrom only) on iPhone OS 3.1.3. (Guide to follow.) It also jailbreaks the iPod Touch 1G and iPod Touch 2G (model number not starting with MC). Baseband 04.26.08 can be unlocked using Ultrasn0w. If your baseband is 05.11.07, GeoHot's blacksn0w will work just the same as it did before. (That was released last year )

    For those of you that have never used any of these programs, please head over to our guides section. Note: We have NOT tested this method. Be smart. Don't do this unless you absolutely have to, or if you want to test and inform others of your success/failure stores Again, THIS IS FOR OLD BOOTROMS OF THE 3GS. If you have jailbroken 3.1.2 previously and the jailbreak was untethered you have the old bootrom. If you have a newer 3GS, just stay away.

    Cash EDIT/

    A couple notes. iPhone 3GS and iPod Touch 2G users check your model number Settings -> General -> About. If it starts with MC don't try any 3.1.3 jailbreak.

    Next, for those of you that do not know, sn0wbreeze is a custom .ipsw creator for Windows much like the dev team's pwnagetool is for Mac. There are things you need to be aware of because of this. First of all grab the correct firmware for your device. Making a custom .ipsw for the wrong device will do you no good. Second the custom 3.1.3 firmware you create with sn0wbreeze is restored to your device via iTunes. Do not use DFU mode, normal recovery mode should be sufficient. Last and most important YOU CAN NOT restore the custom .ipsw that sn0wbreeze makes on to your device unless you device is ALREADY jailbroken. If you aren't jailbroken then jailbreak your current firmware (under 3.1.3) using the software of your choice (redsn0w, balckra1n, pwnagetool, wtvr), then create the custom 3.1.3 .ipsw with sn0wbird, then restore it on to your device using normal recovery mode and iTunes.

    After you have restored your custom 3.1.3 firmware on to your device you can unlock. iPhone 2G users search for bootneuter in cydia. Users with baseband 04.26.08 search for ultrasn0w in cydia. Baseband 05.11.07 users add the repo blackra1n.com to Cydia and search for blacksn0w.

    I have not tried this jailbreak yet so try at your own risk. We'll get a guide up asap assuming everything is working fine (read in 6 hrs when I wake up).

    /Cash EDIT

    Official 3.1.3 Firmware directly from Apple:
    Download iPhone 3.1.3 firmware for iPhone 2G
    Download iPhone 3.1.3 firmware for iPhone 3G
    Download iPhone 3.1.3 firmware for iPhone 3GS
    Download 3.1.3 firmware for iPod Touch 1G
    Download 3.1.3 firmware for iPod Touch 2G

    Download .NET Framework 3.5 (required to run Sn0wbreeze)

    Sn0wbreeze downloads all pulled. IF you find a download, don't use it. We will make a new news post if/when the program is fixed.

      Don't bother with snowbreeze. Use redsn0w 0.9 instead. Read about it here: http://blog.iphone-dev.org/

      I tried using both programs to unlock my 3G. It's impossible.

      Neither are unlocks - if you are on 3.12 you can unlock with BlackSn0w provided you haven't updated your BB to 05.12.01

      No one ever said it did, if you want to use RedSn0w with 3.13 you have to use the 3.12 ipsw.

      Okay, so I have a 3gs below week 40(sim tray). 5.11.7.
      I use a custom restore (3.1.2) ispw, cydia already loaded.
      When I run Blacksn0w, service is always searching.
      If I reset network settings, phone reboots, and gets stuck at the apple logo.
      Ive tried running blackra1n on top of the custom restore, and get the same error.
      I have tried this with different versions of iTunes, and on Windows xp, vista, and 7 (sorry, i dont own a mac).
      Is there any way to unlock custom firmware with blacksn0w?

      First I am new to the Iphone seen. I had my phone about 2 weeks. I bought it from a dude at work. It was NOT jailbroke and was on AT&T. It was on firmware 3.0. I upgraded to 3.1.2 (7D11) Baseband 05.11.07. Jailbroke it and unlocked currently on T-Mobile. I have a 16g MB model I have no idea if it is a 2G or 3G. My phone keeps crashing and now when I connect to iTunes it wants to do a restore. But I know it will ask me to upgrade to 3.1.3. I was wondering how can i tell if my phone will be unlockable using using Redsn0w 0.9.4. I have been reading for the past week and there is something on this site that it will only work with 2G iphones not 3G or 3GS. So how can i tell if I have a 2g or if I have the old boot rom. I have been searching on answers but now I am simply lost.

      Thanks for the the info. I wasn't planning on updating to 3.1.3until I had hard evidance that it would work for me. Can you point me to some instructions on where I can do this. Becasue iTunes is not letting me choose the 3.1.2 firmware it is telling me that it is going to choose that latest Firmware. I tried the Shift + click restore. Also will I need to activate the phone?

      U need a 3.1.2 custom ipsw to shift/restore too otherwise u will have an ipaperweight

      BTW the custom ipsw will activate the 3G for u happens all at one time

      Shift + Restore (if you are on Windows) should allow you to select which ipsw you want to restore to.
      Download the 3.12 ipsw from the download link at the top of this page and restore to that.
      Then use RedSn0w 0.92 (not 0.94) to jailbreak - this will also activate your phone.
      Then use BlackSn0w to unlock.

      Thanks to both of you for great help.


      Today I am only running on 2 hours of sleep but it was all worth it. Here is my story :
      I found a Custom 3.1.2 downloaded. I went through the usual steps to get it loaded on my phone. After several hours of trials and tribulations I was able to finally flash the phone with the new Custom 3.1.2. Phone was jailbroken with Cydia and Icy on it after reboot. Did a lot of research here on what steps I needed to take to now unlock the phone. Per instructions "just needed to open Icy which should of updated to Blackra1n. Use BlackRa1n to get UltraSn0w and unlock. YEAH RIGHT !!!! That was to easy. For me I have to do things the hard way.

      Spent several hours adding sources and trying to get Icy to update so it never did. Decided to delete Icy in Cydia then download the Blacrain RC3 which I originally Jailbroke my phone. Ran Blackra1n on my phone like 5 times and it would never show up. More research time !!!

      Found to add the "repo Ultrasn0w" source to Cydia and install from there. No problem installed UltraSn0w and low and behold phone started searching for signal...Then I get a no service. Yeah told you stuff isn't easy for me !!! Back to google and search.

      Spent several hours trying different things. Removing the SIM. Redoing the entire Process with the Original SIM. Nothing would work. My biggest fear Got this damn phone and a contract for 2 weeks and its all out the window. But I still had hope because I was on 3.1.2 and Baseband 5.11.07.

      Then I read on because I knew that I had never went to 3.1.3 there must be a way to get my service back. then I cam across a post of when 3.1.2 first came out you had to run Fuzzyband to get the baseband back to 4.26.08. (Please read up on Fuzzyband because it will only work with the older bootrom version)

      I installed Fuzzyband ( one thing I also learned is that Fuzzyband helps to tell what your factory bootrom is). My phone was perfect downgraded the baseband....AND BAM !!!! Back in business!!!

      Again thanks to the people I quoted here because they set me in the right direction.

      Please remember everyone, Patience is something you definitely need when testing anything. I test and have tested several things, I have learned that searching and reading works great. It always take longer that way, but in the end just makes you stronger. Last night I learned so much from my experience. I know there is still plenty more to learn.
