| Unfortunately I have some bad news for downgrading. | |
| Before I explain the bad news at the end of this post, I first need to introduce a background of iOS devices. | |
| In iOS 16, Apple introduced a new firmware component known as Cryptex1. Technically, this is a "virtual" co-processor. | |
| It's purpose is to allow Apple to push RSRs (Rapid Security Responses) which are separate from traditional iOS updates and can be installed much faster. | |
| Like other firmwares, it also has a signing ticket locked to a cryptographic nonce (number-used-once). | |
| We commonly refer to the Apple signing tickets as SHSH blobs. | |
| Meaning the firmware can't be installed without a valid signing ticket as well as a matching nonce. | |
| The "big two" components we deal with signing/nonces are AP and SEP. AP is basically the main device chip (Application Processor). | |
| SEP is the security chip (Secure Enclave Processor). | |
| With regards to APNonce, Apple conveniently gave us the com.apple.System.boot-nonce NVRAM property which we use to set the APNonce generator. |
