Sn0wbreeze To Jailbreak iOS 4.1 For iPhone 3GS, iPhone 3G, iPod Touch 3G, iPod Touch 2G For Windows Users Released

Sn0wbreeze v2.0

iH8sn0w has just released Sn0wbreeze, which is the Windows version of the PwnageTool – for iPhone 3GS, iPhone 3G and iPod Touch users to update and jailbreak iOS 4.1.

Sn0wbreeze allows users to create custom iOS 4.1 firmware so that they can update and jailbreak their iPhone and iPod Touch with iOS 4.1.

Sn0wbreeze will help iPhone users to preserve the baseband so that it does not get updated while updating your iPhone with the custom iOS 4.1 firmware. This is important for iPhone unlockers as 05.14 baseband that comes bundled with iOS 4.1 cannot been unlocked.

Please note Sn0wbreeze does not unlock your iPhone, after using Sn0wbreeze you need to use Ultrasn0w to unlock it.

Sn0wbreeze v2.0.1 supports the following devices:

  • iPhone 2G — Works out the box.

  • iPhone 3G — Works out the box.

  • iPhone 3GS (old bootrom) — Requires you to be already jailbroken. (If you are the old bootrom on Spirit or Jailbreakbme use Spirit2Pwn)

  • iPhone 3GS (new bootrom) — Requires you to be on 3.1.2.

  • iPhone 4 (When SHAtter exploit is released.)

  • iPod Touch 1G — Works out the box

  • iPod Touch 2G (MB) — Works Out the Box

  • iPod Touch 2G (MC) — Requires you to be on 3.1.2

  • iPod Touch 3G — Requires you to be on 3.1.2

  • iPod Touch 4 — (When SHAtter exploit is released.)

  • iPad — (When SHAtter exploit is released.)

iPhone 3G users can enable the multitasking and custom homescreen wallpaper features using Sn0wbreeze, which are officially not available in iOS 4 for the device.

Please take a backup of your iPhone or iPod Touch before you use Sn0wbreeze to jailbreak it. Please refer to this post for more details. Please note that jailbreaking your iPhone could void it's warranty so please proceed with caution and at your own risk. 

You can download the latest version of Sn0wbreeze from this link.

Update:

Sn0wbreeze 2.0.2 Released To Fix Error 17, 40 And Hacktivation Problems

As always, please let us know how it goes.

Thanks everyone for the tip!

  • Wolverine

    hi, im an iphone noob. Do i understand it correct that my iphone ios 4.1 (not unlocked) can be unlocked now?

    where can i find a description for that procedure?

  • hxclos

    No because you updated your baseband when you installed 4.1. You can only unlock if you use the custom firmware built by Sn0wbreeze because it preserves the old baseband.

  • sweden

    Maybe is a stupid question but…what is and where I find IPSW file?
    I am stucked on that step. Thanks a lot!

  • hxclos

    Best bet is to just stay there and wait for SHAtter.

  • Hani

    thank you for you great job, but where i can find IPSW file in my PC?

  • Snowy

    That is great news! Poor Apple…I have another question: My friend thinks if he jailbreaks, he will be banned from the App store and his phone shut off from ATT similar to a modded Xbox and Xbox Live. What do I tell him because I know that's not going to happen.

  • chef_khe

    i tryed to jailbreak using the sn0wbreeze 2 but after the phone booted back i still see the dial pad and itunes logo in background . seems the jailbreak did not work , now again back to 3.1.2.

    What are people's impressions of iOS4.1 performance on iPhone 3G? I had upgraded to 4.0 when jailbreaks became available but ended up rolling back because the performance was so bad. Supposedly 4.1 made things better. Is that really true?

  • yoyoman

    I have an ipod touch 4 gen and I want to jailbreak it but this is my first time on my own and i'm totally confused about it. How this thing works? What is the snowbreeze and what is the shatter??

  • Propain111

    Yep you should be able to. There is a tool on the site called f0rcast that will tell you if your iPhone can be jailbroke. Good luck to ya!

  • Propain111

    Here ya go, he is looking for donations at the bottom of the page. http://ih8sn0w.com/index.php/welcome.snow

  • Propain111

    Test it with f0rcast first. You can download it at http://ih8sn0w.com/index.php/welcome.snow

  • sup

    i have no idea what "bootrom" means =\

  • Ed

    This really sucks! I have 05.14.02 modem firmware! So that means that Snowbreeze will not be able to unlock my iphone 3gs? Is there anyway I can downgrade my modem firmware to what is needed? If not this really really sucks! Guess I may have to wait for shatter to be released! I was looking forward to this for awhile now! What's waiting a little bit longer gonna hurt! LOL! Any help would be much appreciated! Thanks!

  • http://AOL.COM Steve Jobs

    no

  • http://AOL.COM mk

    u will be getting an option

  • Ed

    So how would one go about downgrading their firmware to what is needed to use snowbreeze and ultrasnow? Would I be able to do that after already upgrading to ios 4.1 and having my firmware upgraded to 05.14.02? Or was Apple smart in doing that and I am unable to downgrade to use this jailbreak? Any info preferably step by step instructions on how to do this either through my iphone or through itunes would be very helpful! Also when itunes backs up your iphone where can you find these files in itunes or your computer? Thanks.

  • uber-newber

    i get that. if you read above the list it denotes devices that will require SHAtter.
    •iPhone 4 (When SHAtter exploit is released.)
    •iPod Touch 4 — (When SHAtter exploit is released.)

    •iPad — (When SHAtter exploit is released.)

    this isnt mentioned for the ipt3g.
    •iPod Touch 3G — Requires you to be on 3.1.2

    do you see why im asking about SHAtter?

  • Ed

    Help! I am about to restore my iphone 3gs to factory settings with the hopes that it will downgrade my modem firmware to the version needed to use snowbreeze 2.0 and ultrasnow, please let me know if I should do this ASAP! Thanks!

  • sup

    i just found out that it is NEW bootrom! what do i dooo?

  • none

    restoring your iphone to factory settings will not downgrade your modern firmware.

  • Kosmo

    I get error 1600, any help
    (3GS 32gb)

  • Mack23

    I used jailbreakme and spirit to jailbreak my 3Gs. So I'm sort of confused. I'm on the old bootrom I believe. F0rcast just said it was jailbreakable with jailbreak me and such. My Model # starts with MB and I saw someone said that means old bootrom. Not sure. Anyhow, according to what it's saying..I need to use Spirit2pwn to jailbreak on 4.1…even though spirit2pwn is supposedly not by the author that did spirit and could be "false" even though it worked for a few readers.

    So just a little confused. Should I just wait it out for something from the spirit author? Wait for SHatter? Go ahead with the sn0wBreeze? Running 4.0.1 firmware, and not worried about "Unlocking" just jailbreaking

  • kajdas

    me too!

  • xxx

    is it safe for iphone 4 users to upodate to 4.1 and still jb when shatter comes out

  • kajdas

    i hate u people!!!!!!! thx to ur f…ing jailbreake i have new baseband and I have to wait till someone will hack it!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

  • Rob

    Good jailbreak!! After using ireb, iphone booted correctly, 4.1 makes iphone run as fast as it was running on 3.1.3. only problem so far that i cant connect to itunes 10 anyone got a suggestion for that?

    Many thanks tot ih8snow and all the other hackers who keep making these jailbreaks possible

    Rob

  • Eoin

    Ya, I got a friends sim. it took about 2 seconds to active and its working all good now.

    Thanks

  • http://gmail.com shad

    hey do u have 3gs. i just completed restore on my 3gs old boot rom n it didnt activate n is stuck on emergency screen. i checked the activate option while creating customipsw. any clue wat went wrong/

  • Hoobaloo

    I think that is going to be the #1 question with any new jailbreak tool release. Maybe it should be part of all articles going forward. iPhonehacks, you listening?

  • http://profile.typepad.com/iphonehacks iPhoneHacks

    It is a tethered jailbreak for all the devices that have a new bootrom and need to be on iPhone OS 3.1.2 to jailbreak them.

    It is untethered for the remaining devices.

  • Carmella

    Why does my mc iPod touch 2g need to be on 3.1.2?? It's got 4.1 FW cuz stupid me updated it and now i can't downgrade it or restore it to the one that saves on desktop that Snowbreeze 2 creates…can someone please help me out or tell me what to do or wait for…it would be greatly appreciated..thanks

  • Pennywaltz

    Is it downgradeable to 3.1.3? I'm on that right now with my 3G, afraid that my iphone would be slow again on 4.0 :)

  • Rob

    to shad

    No i have an iphone 3G, try downloading ireb from the ih8snow website en see if you can kick it out of recovery mode. If this doesnt work maybe you can try recboot, google this maybe it wil be of any help.

  • kajdasisaprick

    PRICK!

  • jay lou

    i couldnt get it to work just kept timing out for me and stuck me in recovery mode so i had to restore to apples ispw 4.1

  • jl

    wut u need to do is…
    1:build ur ipsw with snowbreeze
    2:use ireb to boot ur phone into the snowflake dfu mode screen.
    once its booted to the right screen it will tell u that its ready for jailbreak…
    3.u then go to itunes and hold shift and select ur custom prebuilt ipsw

  • jay lou

    even if i have the new ispw 4.1 with new basband it will still jailbreak?

  • Goose

    Hey guys, there is a glitch in snowbreeze that does not allow you to activate it. Went on the forums and found a hack to fix it. You have to manually log in to the iPhone via USB and change some files. They are probably going to release an updated version in a few days to fix the glitch but for now don't upgrade until its fixed or you can end up with the "iTunes screen of death"

    Hey guys i have iPhone 3gs on 4.0.2 with baseband 05.13.04 and booloader 6.4. I used forecast to find out if i can jailbreak my phone. At the bottom where it says jailbreakable it says "only with shsh blobs". My phone has never been jailbroke and i dont know what to do with it. Do i hqve to wait for shatter to come out??? Any help would be great.

  • delfynu

    IF YOU RELY ON UNLOCK DON'T TRY THIS. hacktivation patch from pushfix.info does not support 4.1. if you change sim it will apear sim not supported. i had to downgrade to 4.0.1.

  • Stranger

    I am getting 1600 error on Windows, when I used the IPSW on Mac OS I get 1604… have 3GS 4.1 no previous jailbreak. Had such high hopes!!
    I used f0recast to get my Baseband and it’s 05.14.02, I also had upgraded to 4.1 and never jailbreaked this 3GS before. I recently jailbroke an Iphone 3G, that worked so well I want to jailbreak mine as well. What does 1600 or 1604 mean? F0recast said that my phone should be jailbreakable, but it’s just not working, why do we need to use iTunes to restore, obviously Apple has built in errors for this reason. Would be cool if we could restore with a jailbreaker software instead.

    Anybody with 05.14.02 baseband used this and worked? Any ideas? Can I even downgrade?

  • http://www.drunkmunki.com DrunkMunki

I try to restore back to 3.1.2 via pwnagtool because when I connect the phone to iTone it was detected and got the message "iPhone in recovery mood you have to restore". I made a custem IPSW and try to restore it did not work and got Error 1600.

    Sorry Moodi, but that's just too funny… iTone said Iphone in recovery mood LOL

  • http://brittosa.com brittosa

    I think you guys are restoring the custom firmware with iTunes 10. Try it with iTunes 9.2. Seems like Sn0wbreeze's [H]Activate doesn't work with iTunes 10.

    To remove iTunes 10 properly before installing 9.2 uninstall in the following sequence:

    - iTunes 10
    - Apple Mobile Device Support
    - Apple Application Support
    - Apple Software Update

    If you get "Error 0xE8000065" :

    Power off iPhone
    Load iTunes
    Now plug in USB and wait till iPhone boots.
    If no luck, restart phone again while plugged in.

  • Agus

    Dev-team i want to asked if i have iphone4 with OS 4.0.2 than what should i do to unlock the phone?

    you said that this unlock must wait for the shatter exploit, if the shatter exploit is release than what should i do??

    upgrade my iphone4 with itunes or upgrade it with your program??

    n where can i find my bootroom type??

    please advice me.. thanks before

  • cool_dude

    hey guys , sn0wbreeze 2.0.1 really worked on mine and i'm on baseband 5.11.07. but the only problem is the hacktivaton patch , once you install ultrasn0w , the different sim card detected error will appear , and you can’t patch it cuz hactivation patch is only available for 4.0.1 and below and so you’ll need to delete the lockdown folder with i-funbox and install the patched lockdown …………

  • stistud2k7

    Hey guys, I am having a bit of a problem. I have a 3G. I just jailbreaked it from sn0wbreeze and used ultrasn0w for unlock. Btw, I am on t-mobile network. The phone won't unlock. It says searching then says wait for activation and then shows 1 bar and doesnt show carrier logo. Does this mean the ultrasn0w unlock didn't work? Is the ultrasn0w unlock ver 1.1.1 i believe work with ios 4.1? Please let me know asap!

  • cool_dude

    hey buddy withn is ur baseband? check it n i'l help you…..

  • Nicofeine

    does anyone know if the Shatter will be unlocking those who got stuck on 5.14.02 baseband 6.4 bootloader? or is it just for the iphone 4 & ipad? im using a 3GS. thanks

  • melvarius

    Well so far so bad. Iphone 3G f0recast says I should be able to JB but not unlock. I'm not bothered about unlocking it's an unlocked device by default. I've got baseband 05.14.02 and have been JB'd on 4.0.2 using 05.14.02, so I can't see an issue with the baseband. However snowbreeze creates the modded ipsw and when I try to install it the phone gets stuck in Device F* Up mode. Every time I kick it out of DFU it re-boots straight back into it. Also Itunes keeps giving me a 1604 error during the restore. Gonna try another computer when I get the chance and see if that makes a diffrence. Gone back to 4.0.2 for the moment. Ho Hum!

  • stistud2k7

    Hey baseband is 5.14.02 and bootloader is 5.8!

    I installed fuzzyband from cydia to downgrade the baseband to 5.13 but it says doesn't support iOS 4.1.

  • Marvin

    What is the difference between tethered and untethered jailbreak? What does it do? I am kinda new with the terms. Thanks.

  • KK2010

    does snowbreeze work if I am on the blackra1n jailbreak on an iphone 3GS 3.1.2 old bootrom ?

  • Mackie

    Put your Iphone into DFU mode not recover mode and restore. Google for instruction.

  • Mackie

    To all 3G owners,
    It is really not worth to upgrade your 3G to iOS 4. Keep it at 3.1.2 or 3.1.3. There isn't much benefit at all.

  • Mackie

    Google for instruction of downgrade to 3.1.2 firmware then you have it

  • kvs

    doesnt work with me.. used ireb to install snowbreeze image.. but it updated my 3g like default ios4.. now my baseband is updated and unable to unlock it..

    u dnt have any choice
    the firwmare can be downgraded incase u have ur SHSH blobs saved on Cydia, but in any case the baseband can't be downgraded

    Is this mean it cannot be jailbreak if you have 5.14.02?

    I used Sn0breeze 2.0 on iPhone 3g with 4.1 update already installed. It worked fine with only one issue. The Remove BG app from Cydia crashes my springboard and has to reboot. All other apps working fine thus far. Thanks guys, great job. Looking forward to comments for fix Remove BG app
    BTW, I use ATT and didn't need unlock. Happy with ATT in Dallas

  • http://profile.typepad.com/hanginlowe Hanginlowe

    Plug into pc. iTunes must be closed. Hold down power for 3 seconds, Holding Power press and hold Home until you hear the driver load (a 2 tone sound in windows), release power button while holding home button. When you hear reverse 2 tone sound (hardware drop from windows) release home button. Your phone is now in DFU. Launch iTunes. It wil recognize phone in DFU mode and request restore. Restore from an original ipsw, you will not be able to reload custom ipsw, you have to go back through the jailbreak again. Been there, done that. I now and running a 3G on 4.1 jailbroken. I use ATT so don't need an unlock. There is currently no unlock for 4.1

    If that doesn't work, perform above steps without plugging into pc first.

  • cabbit

    It's a problem with Snowbreeze. Follow this here: http://ih8sn0wforums.com/viewtopic.php?f=8&t=3389&sid=5af7c276005a5afce2db074849eb2e1a

    Works great!

  • Mackie

    Look like you have to wait for the new tools

  • Mackie

    Your phone is not dead. Just google for DFU mode instruction and try again. It may take few times, don't panic. You can try Recboot and hey google is the best friend for your success.

    8. When you are asked whether you are already Jailbroken select NO. This will launch the DFU helper.
    9. Remove the SIM from your iPhone. This is an IMPORTANT step and without doing this hacktivation WILL NOT work.
    10. After removing the SIM switch off the iPhone with the dock connector plugged into your iPhone and PC and click Start on the DFU helper. Follow the prompts to enter DFU mode.
    11. Once in DFU mode, open iTunes.
    12. iTunes will prompt to perform a restore. Hold down the shift key and select Restore. Go to the desktop and select the
    sn0wbreeze_iPhone_3G.ipsw and begin the restore.
    13. The restore will complete and the iPhone will reboot. Keep the iPhone connected. It will then be hacktivated. Once hacktivation is complete, reinsert your SIM.
    14. Perform your restore in iTunes.

    I hope this helps guys.

    I'm sorry I'm new to this stuff..

    I jailbroke my 3gs 4.0 using jailbreakme.com without any problem but now i accidentaly upgraded to 4.1.

    Is this mean it cannot be jailbreak if I have Version 4.1 with a Modem Firmware of 5.14.02?

    And how do I check the bootrom from my 3GS iOS4.1?

  • Coolwave

    I just bought a iphone 4, and it was preloaded with firmware 4.1, I know there's no jailbreak out for it yet but is there a way to downgrade to 4.0.1 so that i can use jailbreakme?

    For the step 2, is this the one by holding power and home to reboot on the dfu mode?

    Hello, When I tried to restore the IPSW 3.1.2 that I built, I get an ERROR: 1600

    Can you please help me? Thanks!

  • mlumin8ing@hotmail.com

    To all those getting error messages. I was getting them too. All I had to do was install NET framework 3.5
    That should work. It did for me.

    snowbreeze 2.0.1 hacktivation problem solved

    1) Create a modified firmware in expert mode without activation, flash it and wait until the phone starts up and presents you the emergency screen. Use iREB in case iTunes prevents you from applying the firmware to bypass the error.
    Use a file browser to access the filesystem. iPhoneBrowser does the job.

    2) Now, download the right bundle for your phone from msftguy's homepage and get the file "lockdownd.patch".
    (It can be used in the recent PwnageTool for Mac by the way and activates your phone correctly. You need to do it manually now.)

    http://sites.google.com/site/msftguy/

    iPhone1,2_4.1_8B117.bundle_v0.zip for 3G ,
    iPhone2,1_4.1_8B117.bundle_v5.zip for 3Gs.

    Get the bsdiff_win_exe.zip from http://tpokorra.blogspot.com/2007/11/bs … d-net.html

    3) Using iPhoneBrowser download "lockdownd" from "usr/libexec".

    Place "lockdownd", "lockdownd.patch" and "bspatch.exe" all in one directory on your PC.

    Holding shift, right-click this folder and open a command prompt.

    Enter this command to generate the patched lockdownd file:

    Code:
    bspatch lockdownd lockdownd_patched lockdownd.patch

    4) Do the following steps with iPhoneBrowser on your phone:

    Open the path "usr/libexec" and right-click the file "lockdownd", choose "Replace file..".
    Select "lockdownd_patched", it will be renamed and the permissions will be copied automatically.

    5) Restart. Your phone is now hacktivated.

    i got the same error, help please.

  • mervman

    use to have this error (14). after the snowbreeze 2.0.2 update, the problem is solved. thanks!

  • a bit lost…

    I have a 3Gs now on 3.1.3 jb with JailbreakMe and unlocked. Did the "make my life easy" when was on 3.1.2 (now cydia say SHSH 3.1.2, 3.1.3, 4.0, 4.0.1, 4.0.2). F0recast say basaband 05.12.01, bootloader 6.4, model MC132, tethered "maybe-Depends if refurbished".
    This iphone has never sent back to apple for refurbishing, and i do not have a valid sim to activate in case.

    now the easy question: can i move to iOS4.1 and activate it and jb it and unlock it?
    anyway, thanks for the hard work you've done.

    many tks in advance

    Just jailbroke my 3GS using this method.

    I was on iOS 4.0, already jailbroken. However I forgot which method I used to jailbreak iOS 4.0 So I installed spirit2pwn first and realized I might have used jailbreakme.com. So I uninstalled spirit2pwn and installed JBme2pwn. Didn't seem to harm anything…

    Used sn0wbreeze 2.0.2

    Baseband: 05.11.07

    Works perfect as for now. We'll see what happens over the next few days.

    All previously installed (jailbroken) apps were backed up with PkgBackup. After restoring, non of the icons were there. Reinstalled one of the apps (iRealSMS 3.0) and all the icons came back.

  • *WOOF*

    Thank you to the jailbreak programmers!!!!!!!! Looking forward to 4.2 and shatter jailbreak!

  • BigK

    Hey all a bit of a noob question. I have a 3GS that is running 3.0 that I jailbroke using the step by step on this site. Now I need to update where should I start?
