Other ways to unlock/jailbreak iPhone 3G firmware 3.1.3 baseband 05.12.01 Bootloader 5.8

In Apple device on 03/05/2010 at 2:51 AM

Update:

  • Bad news folks, some of the guys pointed out this iPhone has bootloader 5.8. That is why this method worked 😦
  • So to make sure you can UNLOCK the device, you need to download “f0recast” software from ih8sn0w.com.
  • Run this software, it will tell if you are able to downgrade your baseband and unlock !
  • If yes, run Cydia and search for “Fuzzyband Downgrader”  install and run. And Then let it Sn0w !

Intro:

Yes you read it right, folks ! I am able to install blackrain into my friend iPhone 3G firmware 3.1.3 baseband 05.12.01 sucessfully. And after having blackra1n appear in my friend home screen, the rest is just deadly simple: install Cydia and Unlock phone are 2 fingers away 🙂 The phone specs before the unlock is: Firmware 3.1.3 (Update through iTunes) baseband: 05.12.01 and after the unlock: Firmware 3.1.2 (7D11) baseband: 05.12.01

How can i do it ?

I guess it was my lucky day 🙂 You will need:

  1. iPhone 3G firmware 3.1.2
  2. Blackra1n from Geohotz website
  3. Patience and time cuz you will need to restore the device 3 or 4 times

Ok enough typing here they are:

  1. Connect your phone to iTunes and do normally downgrade to firmware 3.1.2 (Shift click restore)
  2. Ok and when you nearly finish, iTunes will display some stupid errors: 16xx or 2…. It is normal !
  3. Now your iPhone should stuck in Recovery mode like this picture:
  4. iPhone recover mode
  5. That is a good sign. Now next is very long process: What i basically do is run Blackra1n again and again until you can see GeoHotz picture appear in your screen. And then your iphone will have his wonderful application ! Remember that if the iPhone appears black screen for 10mins after you press Make It Ra1n, just reboot it by holding the 2 buttons and run blackra1n again !
  6. Based on my friend phone, it normally took me about 2 times to get GeoHotz screen.( I did the downgrade process 5,6 times to make sure and they were all sucess 🙂 It seems to me that Apple fix is not good enough to 100% block GeoHotz exploit

I did it. How about yours?

  1. I need someone to confirm that this method work on every iPhone accidentally upgrade to 3.1.3. So please if you are successful please post your result
  2. Also i want to confirm that the solder joint i did to my friend’s phone has nothing to do with this downgrade. (My skill at solder is terrible so i am not willingly unsolder and solder the joint myself 😦
