Step 4.

Put the iPhone into recovery (restore) mode by doing the following: with the iPhone off, press and hold the Home button, and then plug the iPhone into your Mac.




You should now see this on your iPhone.




A pop up from iTunes will appear.




You should be at this screen.





Press the Option key on your keyboard, and click the Restore button in iTunes. In the pop up window that opens, navigate to the custom .ipsw file that was saved to your dekstop by PwnageTool at the end of Step 3.




You will see various status bars, while the restoring process continues. If you chose a custom boot logo, you will see it display on the iPhone at this point.




When the restore process has completed, BootNeuter 2.0 will launch automatically. In my case, since I was already unlocked, there was nothing for it to do but reboot the iPhone.

If you were not already unlocked, you will see these screens right after the iPhone reboots. iTunes will prompt you to set up your iPhone at this point. DO NOT TOUCH ITUNES WHILE BOOT NEUTER IS RUNNING! These are the status screens you will see:

Step 5.

The iPhone will reboot at this point. iTunes should prompt you to set up the iPhone. This is your big chance to restore your backup (personal settings, programs, et. cetera) to the iPhone. I chose to start fresh, mainly so I could finish this tutorial quicker.




Now you can name your iPhone and choose some options.




Then this screen will appear, confirming you are on 2.1 firmware.




Note: Cycorder is installed already (I selected it when building my custom .ipsw). I don't see WinterBoard or Terminal installed though...




I find, and this is repeatable, that I need to install something from Cydia (like BossPrefs) once I am jailbroken, to make my other pre-installed applications appear.




You can verify your firmwares in the About screen.
