The iPhone community reacts pretty fast. Just a few hours after iPhone Dev Team released their Pwnage Tool 2.0 a torrent with a modified firmware was published and an option for jailbreaking iPhones with 1.2.0 firmware is now available for Windows users. I personally couldn’t wait until tomorrow so I gave the method a try. I’ve successfully upgraded from 1.1.4 to 1.2.0 version of the firmware. Here are the steps I followed…

Disclaimer

• A method that worked for my iPhone follows;
• This method may not work for your iPhone;
• If you want to do it do it at your own risk;
• A successful outcome is not guaranteed;

Prerequisities:

• Download the 1.1.4 firmware from Apple’s website;
• Download the 1.2.0 custom firmware from The Pirate Bay;
• Download and install WinPWN 1.0 from their website;
• Download and install iTunes 7.7 from Apple’s website;

Make Sure the iPhone is Pwned:

• Launch WinPWN;
• Click the “Browse .ipsw” button and choose the vanilla 1.1.4 downloaded from Apple’s website;
• Click the “iPwner” button to proceed:
• It automatically puts your iPhone in Recovery Mode. If it fails:
  • Try disconnecting and connecting the iPhone;
  • Put your iPhone in Recovery Mode manually:
    • Turn your iPhone off;
    • Hold both the “Sleep/Wake” and “Home” buttons for 20-30 seconds until a yellow triangle appears;
• A message informing that you iPhone is being Pwned should appear;
• A message “Your iPhone is being pwnd. Please wait for reboot.” should appear;

Make Sure the iPhone is Neutered:

• Launch the “Installer” application on your iPhone;
• Install the “BootNeuter” package (available from iClarified source);
• Launch the “BootNeuter” application;
• Select a Bootloader Version (I choose 4.6);
• Enable “Neuter”, “FakeBlank” and “Unlock” options;
• Click “Flash” and “Flash It!”;
• Wait until your Bootloader and Baseband are flashed;

Optionally Put Your iPhone in DFU Mode

• Turn off your iPhone;
• Hold the “Sleep/Wake” and “Home” simultaneously for 10 seconds;
• Release the “Sleep/Wake” and while still holding the “Home” button until the device is detected;
• Wait until iTunes is launched (if not already);
• A message is displayed “iTunes has detected an iPhone in recovery mode…”;
• Click “OK”;

Restore Your iPhone

• Go to your iPhone in iTunes (if not there already);
• While holding the Shift key of your keyboard, click the “Restore” button;
• Pick the custom 1.2.0 firmware you have downloaded;
• Click “OK”;
• Wait until your iPhone is restored;
• After your iPhone is rebooted:
  • BootNeuter starts automatically and flashes your baseband;
  • Your iPhone reboots again;

Troubleshooting

• In case an error 160x occurs during the restore process try the guidelines in Apple’s Knowledge Base;
• If you’re experiencing problems restoring in DFU Mode:
  • Get back to Normal Mode (by holding the “Sleep/Wake” and “Home” buttons simultaneously for some time);
  • Try restoring in Normal Mode;
• In case your iPhone gets bricked try downgrading to 1.1.4;

Have fun!
