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 .ipsw file itself is a compressed archive file (renamed Zip archive) containing at least three Apple Disk Image files with one containing the root file system of the OS and two ram disks for restore and update. tvOS, audioOS and macOS also include a disk image for the recovery environment (recoveryOS).
Solid State Drives (SSDs) work differently than hard disks and are not supported at this time.
To prevent iOS jailbreaking, Apple has made the device boot ROM execute checks for SHSH blobs in order to disallow uploads of custom kernels and prevent software downgrades to earlier, jailbreakable firmware. In an "untethered" jailbreak, the iBoot environment is changed to execute a boot ROM exploit and allow submission of a patched low level ...
Lee Jin-man/AP Apple (AAPL) hit fresh 52-week highs this week, with smartphones accounting for more than half of its sales. Apple sold 13 percent more iPhones than it did a year earlier, and it ...
iOS jailbreaking is the use of a privilege escalation exploit to remove software restrictions imposed by Apple on devices running iOS and iOS-based [a] operating systems. It is typically done through a series of kernel patches.
In the context of free and open-source software, proprietary software only available as a binary executable is referred to as a blob or binary blob.The term usually refers to a device driver module loaded into the kernel of an open-source operating system, and is sometimes also applied to code running outside the kernel, such as system firmware images, microcode updates, or userland programs.
[18] [19] Despite being open-source, Tails contains non-free firmware blobs. [20] Tails includes a unique variety of software that handles the encryption of files and internet transmissions, cryptographic signing and hashing, and other functions important to security. It is pre-configured to use Tor with multiple connection options. It tries to ...
