The careful organization of these components ensures that the device not only runs smoothly after an update or restore but also maintains security by verifying the integrity of the firmware files. The inclusion of SHSH blobs, which are required for validating firmware restoration, further demonstrates the controlled environment that Apple ...
This is achieved by only transferring the differences between the old firmware and the new firmware, rather than transmitting the entire firmware. A delta of the old and new firmware is produced through a process called diffing; then, the delta file is distributed to the end-device, which uses the delta file to update itself. [8]

Apple may be developing a foldable iPhone with a “self-healing” layer on its screen to automatically fill in dents and scratches, a new company patent reveals.. Apple’s leading rivals such ...
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 ...
This is a long process, degrades performance, and if more drives fail under the resulting additional workload, it may be catastrophic. If the drive itself is inherently reliable but has some bad sectors, then TLER and similar features prevent a disk from being unnecessarily marked as 'failed' by limiting the time spent on correcting detected ...

the amount of time required to bring a desired data set back from the backup media. Retention time. the amount of time in which a given set of data will remain available for restore. Some backup products rely on daily copies of data and measure retention in terms of days. Others retain a number of copies of data changes regardless of the amount ...
