Created by developer 1Conan, TSS Saver is the easiest, no-software-required method to save blobs.
Apple's servers will generate the required SHSH blob, allowing the installation to proceed.
Jailbreaks are often released for specific iOS versions. If you are on an older, jailbreakable iOS version, you can save your blobs to ensure that even if you accidentally update, you can return to that specific, vulnerable firmware version.
This system is designed to keep users on the latest software version, ensuring security compliance and reducing fragmentation. However, it poses a significant challenge for jailbreakers and power users who may need to downgrade to an older, vulnerable iOS version to apply a jailbreak. Why SHSH Blobs Matter for Jailbreaking shsh blobs
An (officially known as a Signature HaSH or ECID SHSH ) is a small, unique digital signature that Apple uses to verify the integrity and version of iOS firmware during an installation.
Keep in mind that saving SHSH blobs is essential for users who want to maintain the flexibility to downgrade or jailbreak their devices in the future.
Once Apple stops signing an older version of iOS, your device is theoretically locked into the newest version forever. Or is it? Created by developer 1Conan, TSS Saver is the
Q: How are SHSH blobs generated? A: SHSH blobs are generated through a complex process involving device identification, iOS version identification, nonce generation, hash calculation, and signing.
You can only save blobs for an iOS version while Apple is currently signing it. You cannot "back up" blobs from a version already installed on your phone if Apple has stopped signing it. Popular tools for this process include:
For the technically inclined, SHSH blobs are deeply rooted in cryptography. The system relies on a challenge-response authentication. If you are on an older, jailbreakable iOS
A popular command-line tool that uses saved SHSH2 blobs to restore to a non-signed iOS version. It requires a compatible SEP (Secure Enclave Processor) and Baseband.
(Exclusive Chip ID). You cannot use someone else’s blobs to restore your own phone. The Signing Window : You can only save blobs for iOS versions that Apple is currently signing
Primarily for older, 32-bit devices (iPhone 4, 3GS). The General Process
