Firmware Keys


Firmware keys are used by jailbreak developers to access parts of an IPSW file allowing them to do research, or modify these parts (in a tool such as sn0wbreeze).

I learnt about these when I was writing iKeyHelper - a tool which at the time (mostly) automated the finding of these keys, using the greenpois0n payload. For those curious about how this works, iKeyHelper is open source and available to download from my GitHub. There is also a very informative article on TheiPhoneWiki.

However, iKeyHelper became redundant in February 2013, after @iNeal, @iH8sn0w and I created a set of tools which completely automate the process. This tool is now integrated into the IPSW Downloads Updater and automatically creates the page(s) that you have been visiting on this site.

Frequently Asked Questions

Will this allow me to downgrade my device to x firmware?

  • No. If this were the case, tools would exist to do this.

Why aren't there any keys for newer devices?

  • Techniques for getting these keys do not exist currently. The easiest way to get them requires a low level exploit (i.e. Not user land like evasi0n) and newer devices do not have these available. Update: keys for some newer devices have been added to the pages. Credit to @iH8sn0w and @iNeal.

Why did you make this? Surely we can just use TheiPhoneWiki?

  • IPSW Downloads will get the keys first, and the format of the keys is easy to use and one that developers like (not subject to the moderation of TheiPhoneWiki). An API also exists for collecting the keys data in a JSON format (contact me if you wish to know more).
  • Various bots and other malicious people have been automatically scraping these pages. Requiring a login means I can track who is using the pages, and prevent this from happening.
