Restoring the software of an electronic device to its original state For the Tilian Pearson album, see Factory Reset (album). A factory reset, also known as hard reset or master reset, is a software restore of an electronic device to its original system state by erasing all data ...
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]
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 ...
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 ...
[21] iPhone OS 1.1.4 was the final iPhone OS 1 update for the first-generation iPhone prior to the release of iPhone OS 2, and was released on February 26, 2008, while iPhone OS 1.1.5 was the final iPhone OS 1 update for the first-generation iPod Touch and was released on July 15, 2008 after the release of iPhone OS 2, to users unwilling or ...
Firmware hacks usually take advantage of the firmware update facility on many devices to install or run themselves. Some, however, must resort to exploits to run, because the manufacturer has attempted to lock the hardware to stop it from running unlicensed code. Most firmware hacks are free software.
The most common data recovery scenarios involve an operating system failure, malfunction of a storage device, logical failure of storage devices, accidental damage or deletion, etc. (typically, on a single-drive, single-partition, single-OS system), in which case the ultimate goal is simply to copy all important files from the damaged media to another new drive.
