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

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. i did this on a previously jailbroken/unlocked 2g phone running 3.1.3. i did a restore in itunes first then followed this, and now after the whole process, during the reboot it is stuck on the apple screen. regular apple screen, not the redsn0w logo…. not sure where to go from here? i'm on a mac os 10.4.

  3. Red snow won't recognise any of the ipsw files i download. and now i'm fricken pissed. i lost alot of music because apple is dumb about every thing they do. way to screw up every thing apple. i'm going to go buy a zune now.

  5. hey your the best men this work perfect some onether detail is u have to wait for a litter big and let it reboot for his own and it hoing to be perfect

  6. This works! My boyfriend found an iPhone 2G and it was useless after I foolishly updated it in itunes. I used redsn0w 9.3 on my mac with firmware 3.1.2. Awesome.

  8. There's no Installer App included with this method and I can't figure out how to install it. A google search is leading me in circles. Cydia won't load, it just keeps spinning "loading data" and WiFi keeps crashing after jailbreaking iPhone 2G firmware 3.1.3 on a Mac. I need Cydia to install Installer and I need Installer to fix Cydia. Help? I restored and jailbroke again, didn't work…

  9. hi need urgent solution
    i have an iphone 2g which my friend has unknowingly updated yesterday it has by default updated to 3.1.3 but i cant seem to jailbreak using all methods but have not tried redsn0w will i lose my data if i jailbreak thru redsn0w on windows/mac

    please reply asap

  10. you can connect to itunes and sync all your data but never click update software when prompted! and probably safer to never 'send data to apple' when prompted on the odd occasion also!

  12. I am so grateful. You have shown me how to jailbreak, unlock and activate so clearly. Everything went smoothly and my iphone 2g is now fully functional again.

    Thanks a million

  13. Oh WOW I have tried tons of ways to jailbreak iPhone and those never worked. I LOVES YOU! LOL Thanks alot. (I have iPhone 2G with 3.X version and used Win)

  14. Thanks for these instructions. My previously jailbroken 1st gen iphone stopped booting (only showed the apple logo, then went black). I installed 3.1.3 firmware on itunes, but then it wouldn't activate because it didn't recognize the sim card (tmobile). Found your instructions, followed them, and I'm back in business. Thanks again!

  15. OMG THANK YOU! My 2g was originally jailbroken but i accidently updated it and ruined everything, i didn't have a clue how to jailbreak because it was not activated! This is great! I was DYING!

  17. I'm sorry. I'm going crazy because its not working for me!I have the Redsnow, I downloaded the bootloader files and the 3.1.2 Stock iPhone firmware. Once I open the Redsnow and click browse and open the 3.1.2 firmware it say "unable to recognize specified IPSW". I dont know what else to do. Obviously it worked for everyone, but i dont know why not for me!
    Really really hope you can help me!
    Thank youu!!

  18. Thats you guys, you guys helped me out alot, i had a spare iphone 2g, and i dont got the money right now to buy a new one flat out, so this helped a bunch!! thank you so much!

  22. i have an already jail broken iphone 2g with a 3.0 firmware. i wanted to upgrade it to 3.1.3 firmware, can i use this procedure? will this work even if i had jail broken my iphone before? will this process erase my contacts and pictures etc.? Please enlighten me. Thanks in advance!!
