Jailbreak your iPhone

Jailbreak Unlock iPhone 2G 3.1.2 With Blackra1n Windows Mac


The Blackra1n RC3 software is available for both Windows and Mac (Tiger+PPC) users, and it supports  iPhone 2G, iPhone 3G, iPhone 3GS. Blackra1n RC3 is the most advanced and easy to use utility. Blackra1n RC3 includes the Blacksn0w “ unlock for the latest 05.11.07 baseband ” “ enable official tethering ” and a ” huge 15 second speed improvement ”.  We also apperitiate the stand of GeoHot to declining the $ 10K prize money from Jody Sander. We already published the Jailbreak Unlock iPhone 3G 3GS 3.1.2 with Blackra1n. Here’s the guide that allows you to run the Jailbreak, activation and unlocking the phone part of all the EDGE.  Please note Blackra1n is just for jailbreak later we need a working WiFi connection to Install BootNeuter from Cydia.


Guide to Jailbreak your iPhone

Step One. Download Blackra1n RC3 and double click the rain drop icon to launch the program. Windows 7 Vista users if you have any difficulty in launching the program follow the highlighted instructions otherwise jump to Step Two. I didn’t faced any problem with Windows 7so just in case if Blacksn0w crashes during the launch follow the following three steps otherwise Jump to Step Two.

  • Right-click the blackra1n icon and click properties.
  • Click the Compatibility tab.
  • Under compatibility mode click the box to enable it and select Windows XP (Service Pack 2). Click OK, and then run blackra1n.

Step Two. Click the make it ra1n button.


Step Three. You iPhone will now be placed in recovery mode. You will see a picture of GeoHot that replaces the regular recovery mode screen on your device.

Step Four. Your iPhone or iPod Touch will reboot once blackra1n is done doing it’s thing and you should see the blackra1n icon on there. If you don’t see the blackra1n icon, go to the last page on your iDevice and you should see it.


Step Five. Install Cydia from the blackra1n app. You have the option of choosing Cydia, and Rock. I don’t recommend you to install both of them at once, because that may cause problems. Install them one at a time then reboot and then second one.

Step Six. Open Cydia and run updates essential. Now search for “BootNeuter” and install the bootneuter app.When BootNeuter Starts make sure that the application has following configurations. 2385378772_045094124a

Step Seven : When you are ready click on the button “Flash” and after a few seconds you will have unlocked the phone part of your iPhone 2G a.k.a. iPhone EDGE

Warning do not interrupt the process of flashing : This may take some time before being completed, so you should have a little patience. Another tip while first syncing to itunes set your phone as new phone to avoid long run problems.

    Just a note to say that I had the same unlocking problem with 2g 3.1.2 using blackrain. It jailbroke but did not unlock, seemed to be a boot neuter problem.
    So I tried what SOLUTION from November 11 4.30 am said (put phone in dfu mode, restore to 3.0 ispw, and then use redsnow v.0.7.2) and it worked —it unlocked and phone now works with my rogers sim card (it was at&t previous).
    Thanks and just passing it on in case anyone missed it.

    Hi – i have the same problem like paresh. My iphone (2G) was working fine on FW 3.0, redsno0wed (jail broken + unloked). I have no service after i upgraded (Itunes 9.0.3 + Windows 7). I tried Redsnow 0.7.1, 0.8, 0.9.2, with IPSW 3.0 & 3.1.2; Also tried Blackra1n+bootnueter with (iPhone1,1_3.1.2_7D11_Restore.ipsw). My WIFI, blutttoth, everything works fine. I am confident it is not the HW problem. At times immediately after the jailbreak and unlock I get the service and works intermittently for a short time. I could call and receive calls. Any help is highly appreciated. thanks in advance.

Now my phone is in recovery mode but instead of seeing GeoHot page on iphone I can see a USB cable with itunes sign on my phone. Does anybody knows why this happened and how to resolve this.

    Hi everybody!

    This quide also helped me (iPhone 2G). But after the blackra1n the apps which were installed earlier were not removed. And there was no need to install them again after upgrading.
    And the another thing is that I have installed cydia without wi-fi, just with gprs.

    Thanks again!

  20. Trev January 19, 2010 Reply

    This process cannot work on a locked phone. Once the firmware is installed and jailbroken, the iPhone won’t allow you to access any applications on the phone. This means that you can’t access the BootNeuter to unlock the phone. If your phone is locked then best wait for the DevTeam to PWN the 3.1 firmware. I had to put my iPhone into DFU Mode and roll back to 3.0 firmware and used the DevTeam QuickPwn to unlock the phone.

    Hi I installed blackra1n on my iphone but now I am unable to use wifi as on click of blackra1n app on my iphone it shows message “Please check your internet connection…” though I have a wifi connection on which I am using my laptop also.

    Hi, everything worked fine thanks.

    I first updated with itunes and when the iphone was put in “emergency state” (activation screen), I used blackra1n with XP service pack 2 compatibility to jailbreak.(with no sim card)

    Out of curiosity I placed in my sim card before I installed Bootneuter and it worked 🙂 I think that blackra1n unlocks your 2g iphone as well without the need of bootneuter.

    everything worked perfectly. These steps are the only ones that worked on my 2g iphone when using blackra1n RC3.

    Good effort,
    but a bit risky that one cannot reboot the iPhone without having access to a computer running blackra1n – I’m about to travel and if I for some reason need to restart the phone, I will be out of order 🙁 🙁 🙁

    Oh I’m pretty sure now that it is unlocked I only need your official say about if it really is when I said the things above…
    That’s because when I enter boot Neuter it said it flashed and everything works fine… Please let me know ASAP so I’ll be sure if I can buy a SIM card for the iPhone and start a contract for it for my iPhone cause I don’t have one..:)

    Hi Maddy,
    How can I be sure if my iPhone is unlocked..?
    The modem firmware still states – 04.05.04_G and there is ICCID with blank space on the right that appeared..?
    also when I try to do the process again it gets stuck sometimes before I get to press flash and I have to reboot the device..am I doing something wrong here??
    Please leave some contact details – Skype, or Email…I’ll be very much grateful..

    Hi, I upgraded my iphone2g to 3.1.2 and jailbroke and unlocked it using blackra1n using the above tutorials. It worked real fine. I just want to share few points for the blackra1n users and this might answer some of the qns posed in the comments.
    1. My iphone didnot hv any SIM card while I updated it to 3.1.2 using itunes 9.2. i am not sure if this will make any differnece at all but I just wanted to let you guys know.
    2. Till jailbreak, I follwed the same steps as above. Before installing Boot Neuter, set AutoLock to “Never” in your iphone.
    3. When I flashed the Boot Neuter, the screen hung with “Please wait…. Determining current settings…” message. At this moment, I noticed that my Wifi option was disabled. So I clicked on “Reset Network Settings” in Settings>General>Reset. That is all, my iphone detected my local non ATT SIM card. ANd its working fine.

    Hope this helps.

    Thanks GeoHot for blackra1n and various blogs including ihackintosh (needless to say) 🙂

    It really works for my iphone 2G. After Flash with BootNeuter, if it hang at determine current setting then just quit by pressing the home button and then power off your iphone. Then On it back again and you will get an unlock phone.

    Thanks to the owner of this website as well as the developer.
    I will donate.

    I have a iPhone 2g, I am just afraid it wont work with Cell C, one of our networks in South Africa. Is it safe to try?

  45. Alex December 2, 2009 Reply

    iPhone 2G 3.1.2 here. I tried the blackra1n jailbreak after a previous (successful) jailbreak with Pwnage Tool 3.1.4 (which loads Bootneuter automatically after jailbreaking), but had irregularities with WiFi. These irregularities being:

    About 20% of the time it would connect and keep connected flawlessly, however the other 80% it would be in all possible states of ‘not working’ from the WiFi ‘greyed out’ problem (only occurred once though) to it recognizing all wireless routers in the vicinity but was unable to connect to any of them, be it WPA2 protected or open connection. Sometimes it would connect for a few seconds, but disconnect before you are even able to open any other application, and other times it wouldn’t find any wifi connections at all.

    Now with using blackra1n, I still have the Bootneuter unlock, and the jailbreak went flawlessly and quickly. So I do have my phone capabilities, due to the previous Bootneuter unlock, but my WiFi still has exactly the same problem. I’m beginning to think it might have something to do with my baseband, which is currently still at 04_05_04, although I thought it should have been upgraded to 05_11_07 with my last jailbreak to blackra1n with 3.1.2 firmware. Or am I wrong?

    Does anyone else think my current baseband might be the problem? I’ve pretty much ruled out a hardware problem, since WiFi worked flawlessly for a full two days in a row when first jailbreaked with Pwnage Tool 3.0, and also because it still regularly picks up signals, but just can’t connect to them.
    If it is a baseband issue, how do I resolve/upgrade it?

    This is the first time I’ve jailbroken/unlocked an iPhone, so any info or thoughts on the WiFi issue are welcome. To others who do not have an issue with WiFi, I could maybe suggest using the method of jailbreaking I used before blackra1n if you’re really out of options, to get the Bootneuter to do its job. Afterwards you can still always jailbreak again with blackra1n and 3.1.2, like I did.
    I just hope my method/tools have been the cause of my WiFi issues!

    Any feedback is gladly appreciated, and I hope I could give some insight with my personal experience.

    After reading all the problems with 3.1.2 and blackrain/bootneuter problems with 2G, I’m thinking the firmware 3.0 and redsnow is safer (as described by Solution!!! on 11/11/09).
    I’m getting my 2G iphone from ebay soon. Anyone knows how to check FW version without SIM card?
    Also is the unlocking doable without valid SIM? I’m hoping to use T-mobile one after unlock.

    So i have a 2g with 3.1.2. i jailbroke with blackra1n and then unlocked with bootneuter. I am stuck with a recognized t-mobile signal but can’t get past emergency call screen and it says Different Sim detected….please connect to iTunes.

    When this is done itunes replies with that the simcard inserted does not appear to be supported. Only compatible sim cards can be used to activate iPhone.

    What do i do now? In your answer please tell me if sim card is to be left in or not? do i put in an inactive att sim? I have searched many forums and haven’t gotten a clear answer. I have also repeated all steps many times. Even restore to original form and had to re-jailbreak.

    Please help. So far all advice up to this point has been great and appreciated.

    Was this wrong or was I doing anything wrong? because now I can’t access WIFI and it says “searching…” in the carrier space all the time. another thing – when I enter BootNeuter it says please wait Determining current settings and it won’t end.

    I have an I phone 3G and I have a bit of a problem.

    It’s running 3.1.2, updated today.

    I go through the blackra1n process of jailbreaking, and everything seems to be fine. I have i tunes open in the background while doing this.

    The problem, is when I open up cydia, the phone starts flickering between cydia and an apple icon with a loading bar. If the phone sits idle, the apple icon and loading bar is there, and it loads to about 95%, then stops. I hit the home screen, and it just continues flickering. The only way to get rid of it is power cycling the phone.

    Any suggestions or anyone know if they’ve seen this before?

Not sure of the baseband cause everytime I hook it up to iTunes, it asks me to activate it (btw, I got the phone from my friend) I have tried to downrev the firmware but I get an Error 20 each time. I tried to unlock it using the above procedure but after it reboots, it comes back to the “slide for Emergency” screen and on my PC I am still left with the greyed out “done,wait for reboot” screen from blackra1n. What am I doing wrong??

    same thing and i am realy hope some 1 answer cuz now my iphone 2g is sitting without being used 🙁 plz help

    I found a solution. I did everything with the 2g 3.1.2 firmware to unlock it but the bootneuter didnt work. SO:

    Plug into computer and do a DFU restore (refer to google on how)

    In itunes w/ phone connected hit SHIFT (KEY ON KEYBOARD) + RESTORE, and select the 3.0 .ispw (FIND it on google somewhere)

    Then run REDSNOW 0.7.2 for WIN or MAC

    Continue as instructed. Make sure you hit CYDIA and UNLOCK, not ICY.

    Once redsnow is done. After reboot. I just put in a TMOBILE sim card and i got service no problems, works perfectly!!!!!!!!!!

    OK sooo, I have an iPhone 2g, everything worked great until I opened bootneuter and it’s stuck on “Please wait…. Determining current settings…” what did I do =[ and also when I plug it into iTunes is says that the phone is still in recovery mode…. but if I fix that with itunes then everything will go away…???

    When I get blackra1n on my phone there is cydia, rock and sn0w. I have an iphone 2g 3.1.2 and BB 5.11.07 should I install it?

    I have an iPod Touch and I don’t have Wi-Fi. Is there any way to install Cydia without Wi-Fi?

    OK, I deleted the Blackra1n icon because everything was working fine including the wi-fi. However, how do I get the icon back so that I can re-install snow again? Is there a way of getting the icon back?

    I posted a question a few days ago about procedure, why was it deleted?

    Anyway, can anyone confirm it improves anything over 3.0? For example, my apps/menus often take 8 seconds to open. Better? Wifi reception and password retention better? Battery life better?

    I followed every step a few times everything seems good but when i insert the t-mobile sim card it says “Different SIM detected Please connect to iTunes”? But it does show the carrier as t-mobile.. any help please?

    Yes, Before you do any of the above, open up iTunes and download and install the latest 3.1.2 version. After this, your phone will be back to factory settings. Next, open up Blackra1n and run it and follow above process. I have a 2g iphone and had it unlocked and jailbroken with 3.1. I downloaded and installed the latest version 3.1.2 and followed the above steps and I have successfully unlocked and jailbroken my 2g. Not to be on this guy geohots nuts or anything, but this guy is a genius! I have been unlocking my iphone since way back when and this is by FAR that EASIEST and FASTEST unlock and jailbreak ever! If you have any questions, I’d more than happy to assist.

    I have a iPhone 2G with firmware 3.0.0. Is it guaranteed that I’ll have my iPhone working and unlocked after this procedure? Including the upgrade with iTunes?

    Worked like a bomb for me. I did a SHIFT+Update in iTunes to choose the 3.1.2 IPSW from my hard drive and was pleasantly surprised to note that the firmware upgraded without wiping my phone clean AND without upgrading my baseband! Way to go Geohot!!

    Should I upgrade to the 3.1.2 OS via iTunes before starting this process? Should I use default ispw file iTunes gives me or do you recommend a specific one?
    Thanks Guys!!!

      @USMC7372 Yes update to 3.1.2 first then blackra1n
