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.

Follow the steps below to jailbreak all iPhone’s and iPod touches on OS 3.1.2:

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.

Step 1: Download and install the latest version of iTunes (download link given below).

Step 2: You will now need to first update/restore to the original iPhone OS firmware 3.1.2 on your iPhone by using the latest version of iTunes. Download link for iPhone Firmware 3.1.2 is given at the end of the post.

Step 3: Download blackra1n for Windows (download link at the end of the post).

Step 4: Start blackra1n app. If you are on Windows 7 or Vista, run the app with “Windows XP Compatibility” mode by enabling it from the “Properties” tab to avoid any errors during the jailbreak process.

Step 5: Click on “make it ra1n”:

  2. ok i ran this verbatum and it still does not work. i have never jailbroke this phone before so now what? i even tried to switching to widows xp comp and it erased everything and left me in recovery mode. i has to do a complete restore, lol

  3. for anyone that is having the problem where it gets stuck on ‘running’ and you see the itunes logo an usb cable. move the blackra1n into c:/ and make sure itunes is completely closed, go into task manager and anything in processes that says itunes end it. I had that problem all day and then i tried twice after doing that and now it works

  4. scratch that. IT FREAKIN WORKED!!!!!!!!!!! manual shut down of itunes kicked the bitch in, thank you. i get paid this wednesday and i will be donating money to you brother, that actually was not all that easy but it actually worked thanks to the wonderfully informative posts, noctem aeternus, me

  9. This is BS, this kid couldn’t hack previous attempts and now he fd up kernels on the iphone lol do this and you will fup ure iphone, apple is making it harder for ppl to jailbreak without screwing up other functions of the Iphone i.e itunes

  10. Worked liked a Dream people! just make sure

    1. itunes is NOT running,
    2. make sure all itunes related processes on task manager are terminated
    3. save blackrain exe. in C:/
    4. plug iphone/ipod , iwhatever into the pc
    5. load up and enjoy winterboard again =)

  11. I’m just getting stuck at connect to iTunes screen on my iPhone. iTunes wants me to recover…does blackra1n not do this itself?
    I lost everything on first attempt…2nd attempt is not going anywhere fast!

    Any pointers?

  18. hi
    thank you very much for sharing your experience, could u kindly tell me what fw version u had and which iphone did u have? before trying this method was your phone locked, where it would only show itunes and usb and emergency calls only?
    your reply will help me a lot. please explain as much as u can as i am very new to this iphone stuff.
    thanks once again.

  19. everytime i click make it rain, it puts the phone in recovery mode and i see a usb to itunes logo. is this normal? what do i do? thanks

  21. i have tried to use this over and over again and keep getting stuck at the reboot, all i did was update to 3.1.2, made sure i had the most recent iTunes, plugged my iphone into the computer, closed out of iTunes, ran blackra1n, then the program sent the phone into recovery mode and got stuck 🙁

    any help would be greatly appreciated!!

  22. If you get stuck in recovery mode, disable your anti-virus software! I tried for hours to get jailbreak with blackra1n and once I disabled my anti-virus I was finally jailbroken:)

  24. Looks like the RC1 version is not for everyone. Didn’t work on mine either. Just stalls on the Connect to usb and iTunes screen. Upgraded to 3.1.2 per instructions.

  25. Jailbreak worked great, now I can’t connect to 3g. Wifi works & 3g works fine if I put the sim back in my tilt. Is there a way to fix this or am I just screwed? Thanks

  26. I restored my iPhone 3GS million times, and did blackra1n, but failing in having cracked apps…… this means my iphone isn’t jailbroken?? what should I do? need help pliz!!

  28. Hi all. I have read all your comments, tried everything option listed (disable antivirus, change compatibility,..etc) and nothing worked. I’m still stuck at the recovery freeze as everyone else. I’m tried and wasted serious amount of my sunday. I will try again when something working is available.
    If anyone can post a video of his process on youtube that would definately help us all.

    For developers, I have a virgin iPhone 3G update with the recent update and modem 5.7…

    Thank you for you efforts.

  29. Mine’s doing the same thing. Won’t move past “entering recovery”. Running this in XP compatibility in Vista 32-bit.

  30. Just Jailbroke my 3gs running 3.1 firmware very easy… So happy for Blackra1n you do not have to update to 3.1.2 firmware just follow all other instructions

  31. well is there an answer? never had a problem with new jailbreaks in the past now im experincing same probs as everyone else. STUCK IN RECOVERY, i turned off all virus programs followed the instructions and i dont have nothing

  32. i keep getting an error and blackra1n closes,tried it on 2 different PC’s, iTunes was not even installed on these two computers…i have a mac?what am i doing wrong?how do i jailbreak now :S

  35. IF IT’S STUCK IN RUNNING/RECOVERY, DO WHAT WAS SAID ABOVE AND DISABLE YOUR ANTI-VIRUS AND FIREWALL.

    As soon as I did that, it worked right away!

  36. Sorry I cant be more of an assistance mine went on first try I just left it at 3.1 firmware and did everything else like he said

  37. I have a friend who has a jail broke his phone and he has something installed to where all he has to do is swipe his finger across the top of the screen to turn wifi on or off and 3g on or off. Can someone tell me what that is?

  41. Hi, I have 3gs 3.0.1. i jail broke it using Redsnow and tried unlocking it with ultrasn0w. After down loading and running ultrasn0w my mobile does not start. I tried re-running red snow but it does not work any more, the mobile does not start at all. Can any any one tell me what do I do. Jack

  42. Pingback: StealthCereal | “Geohot unleashes blackra1n upon iPhone OS 3.1.2″ and related posts

  46. If it doesn't work, try closing out iTunes completely before running Blackra1n. AT THE SAME TIME PRESS CTRL, SHIFT and ESCAPE. CLOSE ITUNES MANUALLY AND RUN BLACKRA1N. Worked for me that way-

  48. I did everything on my 3g touch 3.1.2 and his picture showed up now its asking for me to connect ipod to itunes, when i reboot it it asks same thing what do i do?
