How to Save iOS 18 Shsh Blob for Future Downgrades?

Part 1: What is the Shsh Blob for iPhone?

SHSH blobs are unique digital signatures created by Apple for each iOS firmware version on a specific device. They act as a crucial verification tool during iOS installation, allowing Apple to control which versions can be installed. Each blob is device-specific and tied to a particular iOS version.

Apple only "signs" (creates blobs for) current iOS versions, typically ceasing when a new version is released. By saving blobs while Apple is still signing a version, users can potentially downgrade to that version in the future, even after Apple stops signing it. This is particularly valuable for the jailbreaking community, as it can enable downgrades to jailbreakable iOS versions.

Part 2: Is it Possible to Downgrade iOS with blobs?

Downgrading iOS using SHSH blobs is indeed possible, but it comes with certain limitations and requirements. The process is not straightforward and depends on several factors. While having saved SHSH blobs is crucial, it doesn't guarantee a successful downgrade in every scenario.

Factors such as the specific iOS versions involved, the device model, and the availability of compatible jailbreak tools all play a role. Generally, downgrades are more feasible between recent iOS versions and on older device models. However, Apple continually implements new security measures, making downgrades increasingly challenging.

Despite these obstacles, the jailbreak community continues to develop methods to utilize SHSH blobs for downgrades, making them a valuable resource for users who wish to maintain control over their device's iOS version.

Part 5: FAQs about iOS 18 Shsh Blobs

Q1. Are SHSH blobs device specific?

SHSH blobs are unique to each individual iOS device. Think of them as digital fingerprints that link a specific iOS version to your particular iPhone or iPad. This means you can't use SHSH blobs from your friend's iPhone on your own device, even if it's the same model. Each set of blobs is exclusively tied to the device it was generated from, making them non-transferable between different iPhones or iPads.

Q2. Do SHSH blobs still work?

While SHSH blobs remain functional, their effectiveness has diminished over time. They can be used for downgrading or restoring iOS, but only under specific conditions. You must have saved the blobs for the exact iOS version you want to downgrade to, and even then, success isn't guaranteed.
