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!
