However, the utility of SHSH blobs is not absolute. Their successful application depends on several factors. For devices with a Secure Enclave and SEP (Secure Enclave Processor) — essentially all 64-bit devices from the iPhone 5s onward — the SEP firmware must also be compatible. If the SEP from a newer signed iOS version is incompatible with the older iOS version a user wants to restore to, the restore will fail even with valid blobs. Furthermore, modern exploits required to utilize saved blobs, such as Prometheus or futurerestore, often rely on a nonce generator or a bootrom vulnerability—rare commodities that become scarcer with each new Apple silicon generation. shsh blobs

SHSH blobs are essential for several reasons:

Furthermore, the SEP passcode mechanism is designed to protect your data if the phone is stolen. Downgrade attacks (like "Checkm8") historically allowed thieves to bypass Activation Lock by downgrading to an old, vulnerable version of iOS. Apple closed this hard.
