Shsh Blobs Jun 2026

The SEP operates on a completely independent coprocessor that handles sensitive security tasks like biometric authentication (Touch ID / Face ID) and apple pay. The SEP utilizes its own cryptographic firmware, which must also be signed by Apple during a restore.

Because of modern SEP incompatibilities, downgrading on newer devices (like the iPhone 13, 14, 15, and 16 series) is often highly restricted or impossible, even with saved blobs. However, saving blobs remains a harmless, free insurance policy should a new exploit or downgrade methodology be discovered by developers down the road. Conclusion

Jailbreaks rely on security vulnerabilities found in specific, older versions of iOS. When Apple discovers these vulnerabilities, they patch them in the next iOS update and quickly stop signing the older, vulnerable version. If you accidentally update your jailbroken phone, or if your device bootloops and forces a restore, having saved SHSH blobs is often your only safety net to return to a jailbreak-friendly iOS version.

The golden era of seamless iOS downgrading has shifted. Due to strict SEP compatibility and aggressive APNonce randomization on modern chips (A12 Bionic and newer), utilizing SHSH blobs requires deep technical knowledge and often a pre-existing jailbreak exploit. The SEP operates on a completely independent coprocessor

Sometimes, an iOS update introduces bugs, reduces battery life, or alters a user interface element that you dislike. If you have saved SHSH blobs for the previous version while Apple was still signing it, you can potentially use third-party tools to downgrade your device even after Apple has closed the official signing window. 2. Preserving Jailbreak Compatibility

When you downgrade iOS using a saved blob, you must also flash the SEP and Baseband firmware. Unlike the main iOS software, you cannot easily spoof old SEP firmware. You are forced to use the SEP firmware from the currently signed iOS version.

To understand why blobs are so valuable, you must understand the iOS boot sequence and Apple's security architecture. However, saving blobs remains a harmless, free insurance

If you save these blobs while a specific iOS version is still being signed, you can use third-party tools like FutureRestore

(Exclusive Chip ID) and the version of iOS it wants to install.

Even if you aren't planning to jailbreak today, saving blobs is a "better safe than sorry" practice.

If the SEP firmware of the currently signed iOS is fundamentally incompatible with the older iOS version you want to downgrade to, the restore will fail, or your device will boot with entirely broken biometric sensors (Face ID/Touch ID disabled). Conclusion: Are Blobs Still Worth Saving?
