Jailbreak and Update to iOS 5.0.1 with Sn0wbreeze 2.8b11

*UNLOCKERS* Please note that ultrasn0w is not yet compatible with 5.0.1, however there is now a fix. After following this tutorial to update to 5.0.1 make sure you follow our ultrasn0w on 5.0.1 fix.

Today, iOS 5.0.1 was released which addressed battery drain issues with a few other changes as well. For those who are waiting for an untethered , you should not update to because pod2g's upcoming untethered iOS5 will require an exploit that was patched in today's 5.0.1 release. If you don't care about being and want to update to 5.0.1 while preserving your baseband so you can , you can use

DOWNLOAD:
Sn0wbreeze 2.8b11 - Win
iOS5 IPSW(iPhone3,1_5.0.1_9A405_Restore.ipsw)

Step 1: Download the necessary files above. Open up Sn0wbreeze 2.8b11 and you will be greeted with the following screen.

Step 2: Hit the blue arrow to go to the next page and select your iOS 5.0.1 IPSW file that you downloaded above. After you select it, it will verify the firmware and give you a green checkmark like you see below.

Step 3: Now that you have verified your firmware, click the blue arrow button again and you will be taken to a screen where you can select which mode you would like to use. If you are unlocking you will want to use expert mode.

Step 4: Now on the next page you will see some options. Pretty much the only option you need to be concerned about is "Hacktivating." This option will allow users with an unofficial carrier to bypass the activation screen(which requires an official AT&T sim to activate and bypass). It is important that you check this option now otherwise you will have to hacktivate with Redsn0w after this process. The hacktivate option can be found under the "General" tab.

Step 5: That is the ONLY option you should have to change, so now keep hitting the blue arrow until you get back to the main screen and select "Build IPSW" after you click Build IPSW and click the blue arrow again, Sn0wbreeze will begin to create your custom firmware. This process takes about 8 minutes. Once it is done, there will be a custom firmware on your desktop starting with the word "Sn0wbreeze" it will also place an application called "iBooty" onto your desktop. iBooty is the sn0wbreeze version of "just boot tethered now."

Step 6: Now click "OK" on the done screen and you will be taken to the iReb DFU Pwner screen. You MUST be in Pwned-DFU mode in order to restore a custom firmware. Follow the DFU-Pwner on-screen options. Basically you just have to put your device into DFU mode, then iReb will detect the device in DFU mode and put it into a Pwned-DFU state. If you've done it correctly you will see the dialog box below.

Step 7: Now that you are in Pwned-DFU mode, all that's left to do is restore the custom sn0wbreeze firmware that is now on your desktop. Open up iTunes and click on your device in the left hand bar. Hold down shift and then click restore which will bring up a dialog window asking you to select your custom firmware. Select the firmware on your desktop with the filename starting with "sn0wbreeze." DO NOT select a factory firmware, this will update your baseband and make unlocking impossible!

Step 8: After you've restored your custom iOS5 firmware there is just one last step. Since this is a tethered jailbreak you need to now use the iBooty program that was placed on your desktop by Sn0wbreeze while your custom firmware was being created. If for whatever reason sn0wbreeze didn't create an iBooty folder on your desktop, click here to download iBooty 2.3. Open it up and select your device in the drop-down and then select start. Once again, it will walk you through putting your device into DFU mode and then it will exploit your device with the limera1n exploit.

Step 9: That's all there is to it! Once iBooty detects your device in DFU mode, it will boot it up and you should now be on iOS5 with the same baseband you had on 4.x and Cydia will be preinstalled. Remember since this is a tethered jailbreak you MUST use iBooty or Redsn0w to boot tethered EVERY time the phone reboots.

  2. Edu-Br says:

    Hi Guys,
    First of all, you are best for develop such amazing tools.
    I did all like it is suggested but after reset, I pass the Sn0wbreeze running logo and get stuck on Apple running logo, it not get over.
    Do you have any Idea how to fix it?

    Many Thanks in Advance!

    Edu-Br

  3. saikek says:

    Nope, baseband goes only UP.

  4. Spencer says:

    I made a mistake today and upgraded my iOS 5.0 iPhone 4 (baseband preserved with Sn0wbreeze 2.8b8) to iOS 5.0.1 without preserving my baseband. I still have my custom sn0wbreeze_iPhone 4-5.0.ipsw file. I’ve tried to do DFU mode restore with this file but when Apple is verifying the restore I receive error 3194. I’ve add this line (74.208.105.171 gs.apple.com ) to the host file, rebooted, and plugged in the phone to the rear usb, but no luck 🙁

    Any help would would be appreciated. Thanks

    Baseband 05.16.05
    I have successfully jailbroken my iphone 3GS to iOS 5.01….but it shows “No service”
    Can you please help me for this ?
    Tried many ways but still cant help for that.
    Thnx a lot

    • JaeM1llz says:

      The 05.16.05 baseband is not unlockable, you will have to update to 06.15.00 baseband if you want to unlock.

      • Alice says:

        I have the same problem, how can i change my baseband? Everyone says i have to flash in the iPad baseband but nobody told me how

        Redsnow doesn’t offer this option and i’m using mac

        Thank you in advance

  6. tushar says:

    Ur tutorial is useful thnx 🙂
    i just want to ask dat once i performe tethered jailbreak with snowbreeze can i jailbreake it with semi tethered from cydia ?? plz help me out

  7. thunder says:

    Can i use the same tutorial to upgrade from IOS 4.3.4 baseband 4.10.01 to IOS 5.0.1? i don’t need a jailbreak, only to preserve baseband.

  8. Adam says:

    I’m very optimistic… hence needs to double check with all who’ve been there done that. What is there to watch for with a 3gs/old bootrom/06.15.00/ios4.3.3? This tutorial hints about unlocking, so can one plan on unlocking with Cydia after this jailbreak?

    Thank you for pointing all the gotchas.

    • JaeM1llz says:

      All you need to do is update with a custom firmware when you decide you want to update so as not to corrupt your baseband. Since you have an old bootrom 3Gs you will always have an untethered jailbreak no matter what firmware comes out.

  9. Chris says:

    Did anybody else’s icons go missing…I jailbroke with snowbreeze 2.8b11 iOS 5.o.1 and well the got the spinning ring of death and redid the jailbreak and today booted my phone and he icon are gone..:HELP!!! I really don’t kntnto restore again

  19. Jenny says:

    Hi! I have the ios 5.0 and i have allready jailbreak my iphone. Can i update to ios 5.0.1 without losing the jailbreak and the apps i downloaded with it?

    • JaeM1llz says:

      No, there is no way to update to 5.0.1 without losing jailbreak, also you should stay on 5.0 if you want an untethered jailbreak, the exploit that is being used in the upcoming untethered jailbreak was patched in 5.0.1 so if you update you will lose your chance to untether. Please only post comments on one post in the future. Thanks!

  29. dayan says:

    Hi I’m having some trouble in creating an IPSW with snowbreeze. Snowbreeze fails always. It says “snowbreeze has failed to create your custom IPSW” “could not find the file ‘C:/Users/Username/AppData/Local/Temp/sn0wbreeze/locationd’. ” I have tried disabling my anti-virus and running it as administrator and nothing happens. Can u help me with my problem?

    • JaeM1llz says:

      I’m sorry I’ve never heard of that issue with Sn0wbreeze before, I will ask ih8sn0w and see if he has any ideas.

      • dayan says:

        Thank you JaeM1llz. I hope they have a solution to my problem. Is there another way to bypass the SIM activation without its original sim? I have iPhone 3GS

        • Michael says:

          Hi there,
          had the same error as you running snow breeze on xp.
          all i di was add the temp directory to the application data folder, ran as admin and it now works like a charm

  30. Alexander says:

    Hello All, I need some immediate & urgent help…
    Model : Iphone 4
    IOS : custom ipsw 5.0.1 with preserving the base band of 04.10.01.
    Jailbreak : yes thru cydia ofcourse.
    Problem : NO SERVICE on my AT&T GO-PHONE… I tried a lot of things but nothing is working, I don’t have any other operator’s SIM to test my IPHONE4. I got a new SIM from AT&T that did not work, installled RedSnow did not work… Reset all Network did not work… I even tried with GEVEY SIM but my Iphone does not even show single signal bar….
    PLEASE HELP ME EXPERTS…. It’s 15th day with the iphone4 problem….
    THANKS in advance…

    • JaeM1llz says:

      AT&T is an official carrier, there is no need to unlock to use an AT&T sim. If you aren’t getting any service take the phone to AT&T and have them figure it out.

  31. ROLLNO says:

    Does it work with iOS 5.0.1 with firmware 4.11.08?

  32. Reborned says:

    Hello there
    First thank you for your amazing work and nerves to answer to everyone’s questions 🙂
    I had 1 question too.
    I have 3GS on iOS 5.0. My phone is buyer from T mobile and I use their number too, so I don’t have unlock problems so far. BUT I want to have option to unlock my phone later just in case if I want to change the operator if I would want to sell the phone later. Currently my firmware is 05.16.05. I need to go al the way through your tutorial? It will be ok? I will be able to go on 5.0.1 and still with 05.16.05 baseband? And why you keep telling that it’s better to stay on ios 5.0 for unthethered JB. They found how they can make unthetered JB on iOS 5.0.1 I think. It’s a just a metter of time (couple of weeks). Thank you for your answers.
    Keep up the good work!

    • JaeM1llz says:

      When I was telling people to stay on 5.0, that was before Pod2g had confirmed that his jailbreak would work on 5.0.1. People are free to update to 5.0.1 now since he has confirmed it is working on the newest firmware. Any time you update your firmware you just want to be sure to restore a custom firmware and not a factory firmware. Restoring a custom firmware will never update your baseband.

  33. Reborned says:

    And if by some chance if I update sometime through iTunes I will loose my unlock and GPS or there is no damage if I update my firmware but I stay on my current provider? Only when I change provider I can loose GPS?

  34. noah says:

    I just followed these steps using a custom firmware to upgrade from 4.2.6 (i have a verizon CDMA iphone 4) to 5.0.1. My baseband I preserved (even though I’m not unlocking and am on verizon network) and my modem firmware is: 1.0.05

    I am getting no signal from my provider and reading through the comments here it seems that when people have the same problem it’s because of their baseband (which honestly I barely understand yet as i’ve never had a reason to learn).

    please help

    • JaeM1llz says:

      There’s no reason to update with a custom firmware if you are on Verizon. Custom firmware is only for GSM iPhones to preserve their baseband. Restore a factory iOS 5.0.1 firmware and you should have no problems.

    • Anonymous says:

      Nope, restoring a custom firmware will never update your baseband. You should use our new Sn0wbreeze 2.9 tutorial though, this tutorial is for a tethered jailbreak. The 2.9 post is on the homepage!
