SHSH blobs are created by a hashing formula that has multiple keys, including the device type, the iOS version being signed, and the device's ECID. [5] [non-primary source needed] When Apple wishes to restrict users' ability to restore their devices to a particular iOS version, Apple can refuse to generate this hash during the restore attempt, and the restore will not be successful (or at ...

The evasi0n jailbreak first remounts the root file system as read-write and then achieves persistence by editing the /etc/launchd.conf file, which launchd consults. Evasi0n then applies patches in the kernel, bypassing address space layout randomization by triggering a data fault and reconstructing the kernel slide by reading the faulting instruction from the appropriate ARM exception vector.
