In today's tutorial, I will show you step by step how to save / backup your SHSH2 blobs for jailbreak and downgrade purposes on iOS 15.1. Saving the blobs allows you to upgrade/downgrade to iOS 15.1 at a later date when it's no longer signed by Apple, once a jailbreak for it gets released. Saving blobs for A12+ is a bit more work, but it's doable if you have a computer running Windows, Linux, or macOS.

The tool we use to save the blobs is airsquared's blobsaver which is free and open-source on GitHub. The tool supports saving SHSH2 blobs for release iOS versions or for Betas. Definitely save them while you can, before Apple unsigns iOS 15.1.
