Step 2

You can download IPSW files on the IPSW section of this site.

Use the ramdiskstripper script to make a firmware 1.0-1.0.2 IPSW ramdisk dmg mountable. Edit the mountable dmg to your liking. Then use the dmg2z script to make it a ramdisk hack exploitable file. If you need to revert the ramdisk hack exploitable file you made back to a mountable dmg, use the z2dmg script.

Once you have your final ramdisk hack exploitable file, you can use the iPHUC zhack command to boot it if your on Mac OS X 10.4.10-10.9.5. See the iPHUC page for more information.
