Jailbreak, Activate and Unlock Original iPhone 2G 3.1.3 Firmware Using redsn0w [Windows/Mac]

Kiran Konathala • February 10, 2010 • 2 min read

Original iPhones (metal back, silver color, referred to as 2G iPhone) are blessed with a fully unlockable baseband 04.05.04_G. It entitles the iPhone 2G to be easily hackable. So lets get the ball rolling and get to the latest 3.1.3 firmware with a full unlock, jailbreak and activation in place!

Step by Step :

Download redsn0w 0.9.3 from downloads section and extract them to your Desktop [Both Mac and Windows versions of redsn0w are available there]

Connect your iPhone 2G to your PC/Mac and launch iTunes [Update iTunes to the latest version]

Update to 3.1.3 firmware directly from iTunes itself [Just click the update button in iTunes]

Meanwhile, download 3.1.2 Stock iPhone firmware and save it on the Desktop [Make sure it is .ipsw extension and not .zip]

Once the update is done, launch redsn0w 0.9.3 and click on browse button and browse to the 3.1.2 firmware that you just downloaded [Saved on Desktop] and click Next as shown. Follow the screenshots and proceed accordingly [Make sure Unlock and Cydia are checked]

Download the bootloader files for iPhone 2G. Extract the downloaded files 39.bin and 46.bin to the desktop.

When you are prompted for the bootloader files 39.bin and 46.bin in redsn0w , browse to the respective files saved on the desktop and click Next.

Now make sure your iPhone is connected to your PC/Mac and turn it off [Hold the power and slide to power off] and click Next.

Now follow the on screen instructions carefully, it is ok to miss those on the first try. Click back and try again [The 3 steps should as prompted should be done in the time shown on redsn0w].

Now let redsn0w do its thing! You will see some images on the iPhone which means it is jailbreaking, unlocking and activating your iPhone 2G! Wait till you see the homescreen, in other words leave the iPhone alone for few minutes.

Enjoy your jailbroken, Unlocked iPhone!

  1. stucked up on the emergency call screen, when i am running the redsnow and and browsed the downloaded firmware redsnow couldn't recognize the ipsw file i've downloaded. what am i going to do now? help me please,,,,

    1. I believe you are using the latest version of firmware instead of one step lower. For instance, while trying to jailbrak 4.0.1, you have to browse iOS 4 instead of 4.0.1.

    2. hi sugar, i had an issue with redsnow not recognizing the ipsw file. I did a google search on the exact anme of the ipsw file, and found other download links. I then used the other downloaded file, and then it recognized and did the jailbreak unlock stuff no problem. If you need the iphone 2g file referenced above, you can email me at romeomm@hotmail.com and I can email it to you. I may be able to find the download url i used as well. Hope this helps you.

  2. My current situation: my 2g iPhone is stuck on the iTunes logo with the USB cord pointing at it, when attached to iTunes, it says that the SIM card isn't valid, but my T-Mobile card is in, I can receive texts and phone calls, and make calls from the emergency screen to any number. I updated to 3.1.3 on my Windows XP computer, & got locked to the iTunes/USB screen. Redsn0w has the same problem on Windows as on Mac.

    Running 10.4 Tiger, 2g Iphone, updated through iTunes to 3.1.3, but the newest Redsn0w doesn't run on my OS – I got Redsnow 8, and though it won't recognize any ipsw file newer than 3.0.7(I tried official, unofficial, custom from this site, official moved to another folder, unofficial put into the iTunes folder).

    PwnageTool gives me the error of "Wrong Firmware Bundle Selected" no matter which ipsw I try (and attempting it through all 3 different iPhone types).

    QuickPwn doesn't recognize my iPhone is plugged in, trying another port, and another computer.

    Blackra1n doesn't do anything, after running it twice during the reboot hang screen.

    Restoring custom ipsw from this site (after being joined) gives me an error 2001 or error 1500 – won't install through iTunes or redsn0w.

    Redsn0w: only ipsw that would be read was 3.0.7, so I attempted to install that. First attempt hung at "waiting for reboot" on my desktop. Second attempt, I unplugged and replugged, only to have it hang at the "installing jailbreak data" on the iPhone. Third attempt, I got a black screen on the iPhone after redsnow said "done!", then right back to the iTunes/USB screen.

    I then tried to restore through iTunes with the custom ipsw, but I get the same error as before, either 1603, 2001, or 1500.

    I swear, I think I've come across every single error, problem, and bug out there when I'm working on this – I've been scouring the web for each error solution as they come up, any help would be fabulous!

    1. Using blackra1n, you have to quickly unplug the usb cable after the first run. it can make a difference.

      iPhone 2G is the least secured of all iPhones. I would try redsn0w which is a proven software for iPhone 2G on a different machine, preferably Mac. It sure is a puzzle, hopefully you will find a different Mac/PC to try.

  3. THANK YOU THANK YOU THANK YOU. I spent hours trying to do this because stupid me updated software. FOllow step by step and all should be smooth. To all contributors, god bless your talented souls. : )

  8. Thanks I followed the instructions and have unlocked my iPhone 2G. After sitting in my drawer unused for over two years now I can use it again! πŸ™‚

    However I have a slight problem, after I followed the instructions, it worked well and I had apps like Cydia etc on my screen.

    But after I plugged it in iTunes, it automatically restored it again but then I lost half of the apps. I lost simple things like the App Store, Cydia, Mail, and iPod.

    What did I do wrong? I was happy with the result after redsn0w did it's thing, but now that I've lost those apps, I dunno what I can do with my phone? lol

    Any help is appreciated. Thanks πŸ™‚

  12. Thanks!

    I was having some problems with the newer version of redsnow. I found your page here, and although the steps were nearly the same, this version worked. My phone is back up and running, now with 3.1.3 fw. Much appreciated!

  19. Thank you! Thank you!! Thank you!!! Thank you!!!! I tried to "upgrade" to an Android, but it just didn't measure up, so I tried to go back to my old trusty original iPhone. Well, they gave me a new sim card (for some unknown reason) which then would not work in my old iPhone. AT&T people tried everything they could to get it working. Three ruined sim cards later, they had given up. Having no other options, I decided to try to unlock my phone. I have zero experience with any type of computer stuff beyond Facebook, so I was afraid I would fail miserably! These steps were so easy and concise that I had absolutely no problem getting it done. My phone is now working!!!!!!! I am so happy that I am not forced into an unwanted upgrade! Many, many thanks!!!!

    Thanks!
