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. Thanks, worked great on my 3GS. All of my apps from appulous didn't sync at first, then I realised I had to reinstall appsync. Like others I also lost my carrier logo (something to do with the 04.26.08 BB and 3.1 firmware not talking). I simply downloaded MIM (Make It Mine) from Cydia and set it back to O2-UK. Cheers

  5. Awesome, it worked Flawlessly!.

    I was a bit worried, since it gave me this weird "error code 13" but, I did it again, paying attention to what I was doing, and it was done in no time.

    Thanks!

  7. Hi Guys, I am downloading these custom firmwares now for my 3GS. 3.1 (7C144). baseband already shows 05.11.07. Does this mean I can use this firmware or no? I read elsewhere 05.11.07 will not work. Is that true? Thanks a lot

  9. I have a iphone2g on 3.1.2. I JB'd yesterday with blackra1n. When I try the restore in itunes I get the error 'the iphone "iphone" could not be restored'. Anyone know why?

  11. The reason I ask (and apologize for posting a link from another site) is because this is what I am experiencing.

    http://www.cultofmac.com/tethering-mms-hack-broke…

    iPhone 2G on T-Mobile UL and JB running OS 3.1 via Pwnage 3.1.3

    I had MMS on the 3.0 update as well as tethering and have seem to lost them both. Was thinking about replacing the carrier files that I had added when I updatd when going to 3.0 but I dont want to mess anything up. Please advise.

      1. Thank you. I can actually go without that since I only used it a few times but my main concern is getting my MMS back. 🙁 Im stuck emailing pics now, lol.

          1. Nope, still not working. I'm starting to think the phone has been blocked by the network. Can this be the problem?

          3. Yeah i tried it that way aswell hehe. Tried to JB again with blackra1n but its not having it. I am doomed with this phone that refuses to obey lol.

  13. Yeah tell me about. Everyone seems to get a good JB except me :s The error is:
    The iphone "iphone" could not be restored because the firmware file is not compatible.
    I'm using the latest itunes if that makes a difference.

    1. worked flawlesly, one more Question, does the 2G not support Bluetooth Headsets for use with the ipod part of the iphone? I know it works for phone calls. If not are there any 3rd party software that can enable this? thanks again.

  18. Sorry if this seems lame…but lets say I used Pwnage 3.1.3 last week (on a Mac obviously) to get to 3.1 and I want to use this to get to 3.1.2 and I am currently at work on a PC. Will I encounter any problems or have any trouble?

    1. What if I tried installing a MMS repo and it caused my phone to stay on the boot screen but i was able to get it into restore mode, will this get me out of my jam and onto 3.1.2? Sorry for all the questions. Worried that I messed my phone up! 🙁 Thank you.

  21. Thank you, I am currently downloading the files and will follow the step by step instructions and let you know how it turns out. I appreciate all of your help and the quick replies. 🙂 Always makes the situation less stressful dealing with iPhones when someone can reply right away. 😉

          1. I must have been in DFU mode. Saw the cartoon of Steve Jobs come up, knew it was recovery mode finally and am updating as we speak. Hopefully it all goes accordingly.

            ***Future reference for everyone***

            Do NOT install an unknown repo! You will be stressing, sweating and driving yourself mad!

  23. Hey, I got iphone 3gs v3.1.2 Modem Firmware 05.11.07, can i still use the custom firmware for 3gs. I can't jailbreak with Blackra1n for some reason, the phone wont start up after it go to reboot mode.

  24. I have a new 3gs ATT with fw 3.1.2 and baseband 5.11.07 using winXP and when I try to jailbreak it keeps giving me error 1601 I uninstalled and reinstalled I-TunesI confirmed I downloaded the correct (non-activated) firmware and joined them and have the .ipsw extension, any other ideas?

  25. I have the Iphone 3gs Which Was locked and I unlocked it Via Ultrasnow. So now my Carrier is working on this. Right now am not 3.1

    So kindly Let me know which links i have to Download.

    1. Download the non-activated link. I downloaded this yesterday and joined with hjsplit, Worked like a charm now on 3gs 3.1.2 t-mobile mms and t-zones working perfectly.

    2. Download the non-activated link. I downloaded this yesterday and joined with hjsplit, Worked like a charm now on 3gs 3.1.2 t-mobile mms and t-zones working perfectly. And I actually had to put it in restore mode not dfu.

          2. Its the activated link. Sorry I typed it wrong the activated link for non-activated phones. i.e. T-mobile…..
