  10. matt says:

    I have a 3GS 8GB and I use RC6 and the loader wouldn’t open. Thinking it was a problem with the new version of Greenpois0n, I tried RC5 and successfully started the jailbreaking process. When the lines of code were scrolling through my phone it stopped and at the bottom it says “no successful firmware download after 60000 ms!! Giving up…” and it’s been stuck on that screen for a while now. I need help IMMEDIATELY!

    just turn itunes on in your computer then hold power for two seconds, keep holding power and then press the menu for ten seconds, and after that, let go of power and hold menu for 15 seconds until itunes on your computer tells you that your itunes is disabled, then it should let you jailbrake it

    • Ishaan says:

      How did u jailbreak it?
      Can u please tell me the steps of jailbreaking the ipod 3G

      • osmkid says:

        If you use tethered jailbreak, after you do all the steps the program tells u 2 do, you must re-open the program and just select the option ‘Just boot tethered right now’. After that, everytime you want to restart ur apple device, you must connect it to a computer, or all the apps you got from the jailbreak will crash, and sometimes even Safari.
