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”:

Step 6: Let the app do its thing and wait for the phone to automatically reboot.

Step 7: You should now have “blackra1n” in the list of applications on your iPhone. Run “blackra1n”, download Cydia and let it install it.

  25. Hi..i have iphone 8GB 3g..the problm is that i am using it in pakistan..i unllocked it from almost 1 year and the firmwork was 3.0..now i update my iphone from itunes store to 3.1.3 nd its is locked and ..plz tell me what should i do?????thnx.

  26. whgen i go to the downloadf site i try to download the software but it keeps popping up”blackrain has encountered a problem, we need to close down it” so what do i do…..PLEASE HELP!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

  27. Do not upgrade if you want to maintain the unlock. The upgrade will also update your baseband and there is presently no unlock. If you wait a few weeks we expect an unlock from the Dev team for 3.1.3 after apple releases the new version 4 of the firmware.

  28. What is the “in a few weeks” based on? (when the 3.1.3 unlock will come out since apple hasn't said a word about when the next iphone is coming out….)

  29. i would like to know when will iphone 3gs 16 gb v3.1.2 will going to unlock plz kindly help me

  33. theres nothing you can do about it.. just use another computer in order for blackra1n to run normally

  34. i have itouch with 3.1.2, its already running on blackrain. it is possible to upgrade to 3.1.3 ???????????

  37. I followed this guide exacly and the unlock works as well, but after JB I have no sound at all from the phone.
    No ringtones no keyboard klick, nothing and I can not play any Video or music.
    Anybody now about this problem?

  43. Hi I need some advice. I currently have a 3G with firmware 3.0.1 (have been using it to tether) and would like to jailbreak and retain ability to possibly unlock. I plan on updating to a 4, so I would like to play with this one in the meantime. What is the best way for me to proceed? Which tool should I use? How difficult is it to reverse the jailbreak if necessary?

    Sorry for the newbie questions and thanks for all the help,
    E

  44. mine went into recovery mode and now i need to restore my iphone…. everything gone…
