Download Custom Firmware 3.1.2 IPSW – Jailbreak, Activate, Unlock iPhone 2G, 3G, 3GS [Mac and Windows]

Kiran Konathala • October 13, 2009 • 4 min read

iPhone 2G, 3G, 3GS users can now safely update to 3.1.2 firmware without updating the baseband (for unlock). If you are not the one to download all the various files and just want the ultimate result, these files are waiting for you to download! If you rather want to start from scratch, download Pwnage 3.1.4 tool for Mac.

  • Caution #1 : A restore is going to wipe the iPhone clean. Hence, please backup your iPhone using iTunes and then proceed.

More info about these custom firmware files :

  • Has factory boot logos (Apple and restore cable),
  • Only Cydia, No Icy
  • Preserved Unlock baseband (that is the whole point of a custom firmware, right?!)
  • Activated/Not Activated (Check the files carefully)

Prerequisite (recommended) :

If your iPhone is already jailbroken at the current firmware (3.0, 3.0.1, 3.1), it will be a hassle free upgrade! Restore mode will work just fine with already jailbroken iPhones.

Step 1.1) Download Files for iPhone 3GS (Please read the following carefully)

p.s : I am paying for these downloads (purchased RapidShare Download traffic due to overwhelming demand). Please consider donating to keep these downloads free and instantaneous. Thank you…

Step 1.2) Download Files for iPhone 3G (Please read the following carefully)

OR

Step 1.3) Download Files for iPhone 2G (Please read the following carefully)

OR

Step 2) Join the downloaded files

  • The files downloaded above have an extension .001 and .002. They need a special opensource (free) software HJSplit to join.
  • Download HJSplit to join both the files – Link for Windows Computers here and Macs here.

Step 3) Restore the firmware in iTunes 9.x

  • You should now have the respective firmware file with an extension .ipsw (make sure it is .ipsw or else, it will give you an invalid firmware error) . Follow the steps in order :
  • 1)Launch iTunes and connect the iPhone to your Mac / Windows computer.
  • 2)If your iPhone is already jailbroken (if you see Cydia on your iPhone!), put your device in Restore mode (Turn iPhone off, keep holding Home button while you plug it in to your computer). Proceed to step 7. If not jailbroken already, continue to the next step (3).
  • 3)If you are aware of DFU mode, proceed further. If not, watch this quick video and pay close attention to the steps to achieve DFU mode.
  • 4)Turn your iPhone off. Press and hold the Home button and the Power button at the same time for 10 seconds.
  • 5)After exactly 10 seconds release the Power button. Continue holding the Home button until iTunes pops up a message saying that it has detected an iPhone in recovery mode.
  • 6)The iPhone will show you a blank screen (black).
  • 7)Click on ‘Ok’ to the prompt displayed.
  • 8)For a Mac : Hold Option key and then hit Restore button.
  • 9)For Windows : Hold the shift key and then hit the restore button.
  • 10)In the dialog box that pops up, browse the downloaded custom firmware file (the .ipsw file that you downloaded and joined using hjsplit in step 1.x).

Step 4) Give it few minutes to perform the restore. Once the iPhone is up and running, proceed for software Unlock using Cydia. Follow this guide to install Ultrasn0w to software unlock your iPhone 3G/3GS. iPhone 2G is already unlocked with this custom firmware!

You are now good to go! Post a comment if you are stuck at any of the steps described above.

    2. so i have a 2G unlocked and JB firmware 3.0(7A341) modem firmware 04.05.04_G. I just want to make sure if i download the 2G files (activated) above and combine them then restore in itunes. I will still be unlocked right? Im just being extra cautious cuz i skrewed up my 3G a few weeks ago. thanks for your help.

    3. Question. I used the activated 2g one since I am on tmobile. If I instead used the NON activated one, and restored in iTunes with a spare ATT sim I have, would I still have my unlock? I'm thinking of doing it, and letting it activate that way so that I can receive push notifications.

          1. Valid contract means – it activates the iPhone for you and you don't
            have to unlock to use it (you can unlock it later though)…

            Non-Valid contract – you need to jailbreak it to activate it and you
            have to unlock it to make it work…

          2. Since I'm already unlocked, will the Valid one remove that?

            Basically, I am unlocked using your "No-Valid" one. I'm wanting to restore with the Valid, use an ATT sim I have (although its not in use, when I put it in my phone and connect to itunes it shows a different phone #) to activate and get Push working. Then maybe unlock somehow. I'm on a 2g.

          3. You can always unlock your 2G iPhone no matter what since the baseband
            is unlockable directly, Apple stopped working on it.

            For push, simply try reflashing to 3.1.2 and then activate it using
            ATT sim and then you may use blackra1n to jailbreak.

  11. I ha ve a question here
    I have a new iphone 3gs 3.1.2, and i am not able to unlock it , i can only see the emergency call screen
    I used blackra1n to jailbreak, jailbreak was sucessfull but iphone didnt unlocked
    Now if i dwnld from will my iphone be unlocked without the at&t official sim and somebody told me that if i use custom firmware my iphone's baseband would change and it wont jailbreak ever, nor it would work with the official sim

    2. Similar problem – I'm on 2G 2.1 firmware (jailbroken). I put it in restore mode (I see a caricature of Steve Jobs), then when I choose the 179,200 KB file (ipsw) it says it's not compatible.

  13. Awesome posts man your the other person that I can find that is willing to do this. And when I awoke i saw the blog post from the dev team and you were already ahead of the game. Thanks a lot keep it up!

  14. Does anyone else have the problem where the rapidshare download is going from like 300kbps to 0 and sitting on 0 for about 20 seconds and downloads just a little bit at a time?

  17. ok got a question…

    i currently am using an iphone 3gs on an official carrier (t-mobile netherlands) but i want the unlock option to be available just in case something happens in the near future. that means i should download the activated firmware but would that affect my use of the official carrier now? what should i do?

    thanks

  20. I have iphone 3gs US ATT contract, i will need the phone with other carrier in future travel. I JB and UL using this site previous Custom firmware 3.1 on windows Vista. Which of the above should I download.
    ATT and Others or T-Mobile and Other, and what differ between the 2.

    Many thanks

  21. I have iPhone 3GS with the following serial # MC137LL running 3.1 fw and already Jailbroken and unlocked to be used with my local carrier. now I'm confused which custom IPSW to download? the one in the first link or the second one. Any advice plz.

      1. Thank you for the quick response. I imported my 3GS from the states and I don't have contract. Used redsn0w to unlock it and now I'm using my local carrier. So the activated FW is the choice right?

  24. doesn't work on my 3gs, the dev team said that you can use it on software out of the box (Note for 3GS users not already jailbroken and stuck at 3.1.x: this version of PwnageTool has a side feature to jailbreak your 3GS. It uses a simple implementation of the usb control msg hole found by chronicdev, geohot, and our very own gray.), but your custom firmware doesn't work, I know I'm asking A LOT but could you post one that doesn't preserve the baseband for users who had 3.1 out of the box or who updated officially to 3.1.2 because they don't need the unlock? thank you, even if you can't upload that ipsw πŸ˜‰

  25. I created a custom IPSW using Pwnage Tool 3.1.4 for my iPhone 3GS but keep getting error 1600 when trying to restore custom firmware (DFU Mode) in iTunes. πŸ™
