This is Part 1 of a two-part guide on how to use futurerestore.
Before attempting this guide, everyone should read the introductory article, Guide to futurerestore: Introduction. It will explain whether this guide applies to you, as well as making sure that you fulfil the requirements for it to work.
If you currently have a jailbreak and you want to move to a different firmware with futurerestore’s generator mode, you must follow this guide first before following Part 2.
If you currently have no jailbreak, and you want to move to a different firmware with futurerestore’s Apnonce collision mode, you can skip this guide and head straight to Part 2. This method does not apply to most users.
