Jailbreak iPhone 3.1.2 Firmware with blackra1n

George Hotz (aka geohot), the kid who was the first to unlock the original iPhone back in 2007 and then iPhone 3GS in July of this year is back! This time he is the first one to release jailbreaking solution for the new iPhone 3.1.2 Firmware for all devices through his new tool called blackra1n. blackra1n is a software tool which can jailbreak (not unlock) all iPhone’s (iPhone (Edge), iPhone 3G and iPhone 3GS) and iPod touch’s (iPod touch 2G and 3G) running on firmware version 3.1.2. blackra1n is currently for Windows only, a Mac version of this app can be expected soon.

UPDATE: An updated version of this guide for blackra1n RC3 with blacksn0w can be found here.

So, what is blackra1n? blackra1n is a 30 second ALL device 3.1.2 jailbreak. Even the ipt3, but the ipt3 is tethered. In order to boot it, just rerun blackra1n.

  3. This worked for me. OS X blackra1n. Thanks very much! I had used pwnagetool, and bricked my 1 day old 3gs after breaking my 3g (left on car) the day before. Got it to finally come out of DFU mode by restoring official 3.1.2 using iTunes. Was getting 1600 errors non stop, and no screen, no apple, no iTunes logo, no nothing. Just black no matter what. So when I tried blackra1n and it wanted to restore again, I was less than happy till I found this post. Much appreciated Teagan!

  4. I tried this and it ended up fucking up my fone. It wouldn't let me restore it it just gave me an error I had to get a replacement fone. I don't recomend this

  5. if you are having problems getting you phone to jailbreak, disregard instructions in step 4 above as far as running in “compatibility mode”. My phone would not jailbreak until I unchecked “run in compatability mode” under properties, then it ran flawlessly.

  7. hi, im having the same problem as burjisp. i follow the steps and just keeps coming up with the itunes and usb screen 🙁 i did manage to install the blackra1n once but nothing worked so i restored my phone (3g) and now cant get any of peoples steps including urs. can u help at all??? as u seem to have the best explanation so far 🙂

  9. Hey Teagan,
    you saved my day after a lot of trials with other instructions before:-)
    Your steps are working perfect….also with Vista.

    cu and thanks a lot.
    Thommy

  10. I Love You brother.. yo the man.. and GeoHot.. and this website.. i love you all woohooo thank you

  12. How do you change the color on the keyboard..everytime i try and change it, it doesn't work..if someone knows how to change it..please let me know ..thanks

  13. hey man i dont have any luck every time i click make it rain, my screen will just turn black what to do ?

  14. If my iphone 3g is already jailbroken can I just update it to 3.1.2 through blackra1n or do I have to make a backup of my phone and restore then use blackra1n?

  15. Worked flawlessly! Too simple! Thank you..
    I have a 3G
    Was scared it wouldnt work from other comments
    but all I did was

    Updated my 3.0 JB phone to 3.1 using itunes..
    Turned off ituneshelper.exe through task manager
    and.. made it rain! by just sitting there =) and blackra1n's dl of course
    Checked all was workin.. Yup!
    Installed Cydia with blackra1n

    No problems!

  17. I just completeled the jailbreak, took roughly 30 seconds. running windows xp SP3 as admin, using 3.1.2 and latest itunes. worked flawlessly. I highly recommend, to all of those trying this make sure to follow the guide to the T. that means software version and each step, I tunes may try to get you to sync once the phone reboots, I closed this out as to unsure what it would do (clicked X did not presss OK)

  19. So, if I want to do this in a Linux OS should i go through wine? (which is normally dissapointing) or do I need to build a virtual box with windows? I would rather not, and I know it's ridiculous not to have a single windows os running, but I tend to overlook these things, I have already done this once using wine to run a win32 version of Itunes, nevertheless it didn't work and (this isn't your problem but…) I couldn't read anything so I navigated my way using screenshots. I just don't wanna have to do this again. I'm lazy.

  20. check your phones settings, the userinfo number should match, if it doesn't something is wrong. I would google it, google is your friend.

  24. hey will i this work for my OOTB iphone 3Gs 16gb firmware 3.1 upgraded to 3.1.2 throught itunes
    ps. The modem firmware is 05.11.07

  25. hey will this work for a iphone 3Gs 16gb OOTB 3.1 upgraded to 3.1.2 through itunes? btw its modem firmware is 05.11.07

  26. I’m having real troubles with this, I’ve restored my new 3.1.2 3gs back to original, the jailbreak all seems to run flawlessly.

    Start blackra1n, click make it rain, it restarts into DFU mode, then geohot appears, it says successful and reboots, but then it comes up in DFU mode again. If i start blackra1n again then it jailbreaks it again reboots it and I’m back in normal mode, can install Cydia etc, but if I then reboot the iPhone again, its back in DFU mode. Running blackrain again gets it back into normal mode but the same thing happens on every reboot.

    Am I missing something?

  27. I ccidentally downloaded the blackra1n to jailbreak (thinking there is away to unlock the phone — I know I should have read all the description), but I don't know what to do.

    It is unlocked — everything works except for the phone function.

    So … what do I do next. I read in a website that the unlock code is coming, but when and where should I exactly look.

    Is there a person who can unlock it for me? I don't mind paying the price.

    Help me and I am totally getting frustrated; especially when I am not a techno person!

  30. I follow all the steps but then when I download and install the video record app on cydia, it goes on the splash screen where is says “loading” and immediately just crashes. Also happens on regular apps I had install on prior to the jailbreak like facebook. It would just pretend to load the splash page and then crash/disappear. Anyone else had this problem?

  38. Is blackra1nRC2 tethered for iPhone 3g and 3gs? First blackra1n was not, I know this for sure because i've rebooted my 3gs number of times and i did not have to re-run blackra1n again!

  41. Ok, I understand now, OOB 3.1.2 can be Jailbreaked but is tethered due to the bootcode update so will require blackra1n to start up again.

  42. i just did what teagan said and everything went well. i jailbroke my 3GS on the first try and i just got it an hour ago. thx teagan

  45. hey! I did this, and everything is fine, except this:

  48. wir87:

    blackra1n will NOT unlock the phone, there is at least 2 warnings telling you this, it will just jailbreak it:

    Note for iPhone 3G and 3GS: Do NOT upgrade to iPhone 3.1.2 with blackra1n if you want to keep your unlock as doing so will result in upgrade of your baseband which will make it almost impossible for you to unlock.

  49. dude you can NOT unlock your iPhone anymore
