Welcome to the custom-ipsw-script wiki!

The function of this script is creating a custom ipsw that can be used to Dual boot your Device. It'll take files from one ipsw, patch them with Predefined patches in a bundle in the "FirmwareBundles" folder. It will not change any ipsw in any way, unless you tell it to.

IMPORTANT:

This is not the ideal method of dualbooting, since it involves messing with the NOR and may cause problems with both NAND and NOR. Unless you don't know what you're doing, you should not try this out. There are way better methods of dual booting, wait before doing this.

General Warnings:

You should not try this on devices you need. It can cause problems with them. Try this out on old devices first. Currently there is only a Bundle for the iPhone3,1 6.1.3. Others may be added in the future
