Sn0wbreeze 1.4 Released to Jailbreak and Unlock iPhone OS 3.1.3

Sn0wBreeze - PwnageTool for Windows

iH8sn0w dev team have released Sn0wbreeze 1.4 to jailbreak and unlock iPhone OS 3.1.3. However, please read the post carefully before proceeding.

Sn0wbreeze allows users to upgrade from a jailbroken iPhone OS 3.1.2 or lower to iPhone OS 3.1.3, which was released few days back to fix some minor bugs.

sn0wbreeze is a tool for Windows that will jailbreak your iPods and iPhones, setup custom boot logos, activate your iPhone, root partition size, build custom IPSW, and more!

As mentioned earlier, Sn0wbreeze will work ONLY if you have an iPhone or iPod touch running iPhone OS 3.1.2 or lower, which has been JAILBROKEN or PWNED. It will NOT work if you have already upgraded to iPhone OS 3.1.3. It allows users to upgrade their jailbroken iPhone runing iPhone OS 3.1.2 or lower to jailbroken iPhone OS 3.1.3.

It can jailbreak the following devices:

  • iPhone 3GS (OLD BOOTROM ONLY. If the 4th/5th digits of the serial # are before 40 then you should have the old bootrom. If your current jailbreak is tethered DO NOT try this.)
  • iPhone 3G
  • iPhone 2G
  • iPod Touch 2G (OLD BOOTROM ONLY. If your current jailbreak is tethered you have the new bootrom so stay away and/or If your model # starts with MC you have the new bootrom so stay away!)
  • iPod Touch 1G

And it can unlock the following devices:

  • All iPhone 2G
  • iPhones with 04.26.08 Baseband
  • iPhones with 05.11.07 Baseband

(You can find your baseband via the Settings app (General->About->Modem Firmware)

You can download the latest version of Sn0wbreeze from iH8sn0w’s website.

Please remember hacking your iPhone could void its warranty. So please proceed with caution and at your own risk and don’t forget to take a backup of your iPhone (refer to this post for more details).

As always, let us know how it goes.


Dev Team have released PwnageTool 3.1.5 and Redsn0w 0.9.4 for iPhone OS 3.1.3

    Any purpose of upgrading to 3.1.3?

  • Good point, assuming the bugs that have been fixed in iPhone 3.1.3 are really bothering you.

  • Bullfrog

    First…ha ha, seriously, I will only upgrade if this fixes the
    3.1.2 battery issues. I had to downgrade my 3gs
    back to 3.0 to have a decent battery life. Most likely
    will wait for Dev Teams solution.

  • cosmo2389

    If you upgrade to OS 3.1.3 can you still tether using the profile install like you could on previous OSes?

  • Sean

    So this doesn't jailbreak my 3.1.3 🙁 ?

    My stupid friend upgraded my phone !

  • lsaman

    You have a good site, but it is so much difficult to read posts from it. I think there's something to be done. you 'll have to decide a better place for advetisements.

  • steve

    works fine battery last much longer I think I did my phone 5 hours ago and battery level still on full

  • steve

    no if you can downgrade using tutorial you be able to then jailbreak using this that's if you saved your file on cydia

  • Wes

    Kinda confused…if im already jailbroken and i use this…THEN i upgrade to 3.1.3? im running a 3Gs old boot rom on blackra1n with 3.1.2 someone let me know pls….

  • MonicaPressley

    working on my at&t 3GS. But I cannot get native internet tethering to work. I tried MyWi, but the option to toggle on is there for a second and the disappears. Tried mms and tethering settings from all over even help.benm nothing works.
    anybody got any ideas?


  • waseem4u

    Is this upgrade also updates the modem firmware from 4.26.08 to the newest one?
    I have a 3GS, just returned back to 3.0 because of the battery life.
    After upgrading to 3.1.3 can I still go back to any version i want? I have SHSHs on file for 3.0, 3.1, 3.1.2 with cydia.

    Please help

  • square

  • Josh

  • kratos

    these are the last days of jailbreak!!!!!!! too bad. there are no new exploit!!!!! found.

    What we will do when iphone 4g comes out with iphone os 4.0 or iphone 3gs factory installed 3.1.3

    fu****ck u apple.

  • sam

    dev team said if u have the new boot rom do not come near this will that mean the nex generation of people will not be able to jailbreak.

    ****apple is shipping 3gs with the latest firmware***

    i appreciate the dev team for there hard work very much but we are losing The battle!!!!!

  • steve

    last night big problems but this morning snowbreeze released v1.4 it it worked as long as your on 3.1.2 jailbroke old boot rom you be ok

  • Jon

    my jailbroken 3gs 3.1.2 went kaput on me yesterday. i lost cell reception in the moutains, so i put it in airplane mode thru sbsettings. and it just froze and i had to shut it down. went home and tried to turn it back on via tethered blackra1n like usual, and it keeps hanging on the geoh0t screen before going back to restore mode (usb to itunes screen). i know i have my ecid shsh thing on cydia, but for some reason, modifying my host file didnt allow me to restore to 3.1.2. so i was forced to restore to 3.1.3. anyone have any idea on how to get back to 3.1.2?

  • kratos

    u should be able to go back to 3.1.2 since u have ur shsh with cydia,

    u have to proply direct itunes to jay freeman servers otherwise it will not work.

    try this

  • kratos

    also u have to put ur iphone in DFU mode not the one with itunes pic

    search youtube dfu mode

  • Ricardo

    hello i have a question. have an iphone 3gs on 3.1.3 never jailbroke it and it's model number starts with MB. so which program, if any should i use to jailbreak it.

  • rEiNiEr

    since your phone is working fine, a piece of advice, just stay away from it at the moment. If you need an unlock, some people are reporting issues on blackra1n compatibility, it could mess up your unlock.

  • rEiNiEr

    Using sn0wbreeze will not upgrade your baseband. As for downgrading, some have already tried downgrading to 3.1.2, not sure about lower.

  • rEiNiEr

    sorry, but there is none at the moment.

  • rEiNiEr

    piece of advice, stay away from the update at the moment. there are some reports on issues regarding blacksn0w compatibility if you need an unlock.

  • rEiNiEr

    there's an update for sn0wbreeze, v1.5.1. have not yet tested.

  • Devin

    how do i downgrade my software back to 3.1.2 can i

  • Vicky

    Hi, I am from india. I am unable to upgrade to 3.1.3 and i am still struck with 3.1.2. My itunes when connected tells me that 3.1.2 is the latest and it does not indicate any upgrades what so ever. Pls help as to why i am unable to upgrade.

  • rEiNiEr

    maybe you need to update your iTunes if it wasn't. are you sure you really just want to update to 3.1.3? no jailbreak or unlock?

  • Simba

    i just upgraded and jailbreak my iphone 3g 2.2.1 to 3.0. the last step was to sync with itunes but upon sync with itunes it asked me to upgrade to 3.1.3 and without doing so i cant switch on my iphone. so i want to ask is it safe for me to upgrade it to 3.1.3 and use sn0wbreeze 1.4 to jailbreak it and so on? thanks

  • rEiNiEr

    if you update to official 3.1.3, your baseband would be updated, but you may try redsn0w instead, to jailbreak without unlock. Otherwise, use sn0wbreeze to make a custom FW, to retain your current baseband. PS. try to use an earlier version of iTunes, maybe 8.x

  • Simba

    cool redsn0w it will be, thanks. but is there any possibility that it would make my iphone not being able to operate?

    are there any requirements i should know before i jailbreak it, just to be on the safer side?

  • bogart

    i have a jailbroken iphone 3gs on 3.0.1. baseband is still 04.28.08. how do i upgrade it to only 3.1.2 preserving the jailbreak and baseband?

  • rEiNiEr
  • i was wondering if anyone knows whether you will be able to jailbreak the iPad (not ipod) like the iphone? desperately keen to find out 

  • fingers

    As with all jailbreaks, they take time, i have NO doubts that the Dev team will figure out a way to jailbreak the iPhone 4G when it arrives, even if it does take time. Pretty sure it would take less time if people didn't pester them! We're not and never will lose the battle with Apple, thanks to the genius of the Dev!

  • snooky

    i have iphone 3g 3.1.2 its unlocked and jailbroke i used blackrain i been looking for days if i upgrade to 3.1.3 can i unlock it i have tomobile so it has to be unlocked for me to use it if it can be unlocked will someone please tell me how to unlock it

  • rEiNiEr

    if your unlock depends on blacksn0w, stay on 3.1.2, but if you're using ultrasn0w, then you can either use sn0wbreeze or PwnageTool.

  • dan

    I tested out sn0wbreeze 1.4 today on my jail-broken & unlocked 2g. The result was less than satisfactory. Once I was done, my experience was my edge/data connectivity was gone. The T-mobile logo and any connectivity signal were all gone. I waited for a couple hours, but nothing changed. So, I had to downgrade my OS back from 3.1.3 to 3.1.2, and my phone now works fine.
    One cool thing it has that I admire is doing the jailbreak process, Sn0wbreeze can build a custom ipwn firmware and place it on my desktop. This is cool.

  • nvmyre

    i downloaded sn0wbreeze and it says file is corrupt why would this be

  • Apel Papa

    quick question my phone was already jailbroken and when i connected it to the cmptr it automatically updated to 3.1.3 and erased all my blackrain and cydia and my phone has been locked from westcentralwireless please help

  • Calvin

    My tethering suddenly disappeared and force me to reboot my iPhone then I got freeze at the apple logo. I had no choice but forced to restore with 3.1.3 …i'm so screwed! F****king Apple. If I can't get it jailbreak i'm going to cancel my AT&T and using Android instead 🙁

    I got it reversed back to 3.1.2 but the baseband stuck at 5.12.01

  • simon

    hi i have iphone 3gs 3.1.2 fw, but in cydia front page its say that i have 3.1.3 on file.can you tell me what does that mean.mine is 3.1.2 not .3.1.3 and how come its say 3.1.3. thank you

  • allex

    it doesn't work at all!!!

  • dave

    like the experts say im staying away from 3.1.3 until the DEV team comes up with a solution, by the thanx alot guys. i have faith in you.

  • Genius

    This method worked fine for me. Remember you have to have a phone that had the 3.1.2 or lower that was already jailbroken and with the old bootrom for this work. I had a 3GS, 3.1.2, old bootrom, with baseband 5.11.07. I jailbroke 3.1.2 before doing this method to restore to a jailbroken 3.1.3. THIS WILL NOT WORK IF YOU ALREADY UPDATED TO 3.1.3.

  • Richard

    Will there ever be a jailbreak and unlock for iphone 3gs 3.1.3 to work on t-mobile??????

  • Craig

    I was on 3.1.2, then thru error landed on 3.1.3, i noticed decreased battery life on 3.1.3, i also noticed bugs in Safari – pages dealayed when closing, and finally i noticed decrease in volume output.

    I've just rolled back to 3.1.2 and i don't have those gremlin's no longer.

    In my experience 3.1.3 sucks all round, avoid if possible.

  • Craig

    Stay away from 3.1.3, have you all gone mad?!
    God, wait ffs, 3.1.3 is shite, stick with 3.1.2 if you can!!

  • Craig

    If you're with o2 UK, ask them to officially unlock you, i did, and i'm on t-mobile now, brilliant network (least where i live)
