Apple smartphones and tablets are renowned for the smooth operation of software and hardware. Due to this, the smooth operation of the devices is achieved, and the American corporation eliminates any problems with the firmware in the shortest possible time due to updates. In this case, the user may need to reflash the iPhone or iPad. You can do this yourself, without the involvement of a service center.
The concept of flashing a device refers to its restoration. This process should not be confused with the update, because it has one cardinal difference: performing recovery, all data from the iPhone or iPad is permanently erased. After flashing, the device returns to the factory settings, and data recovery will be possible only with a backup.
Why flashing iPhone or iPad
Nothing is safe from software crashes, including Apple devices. Despite the fact that one corporation is responsible for the development of hardware and firmware, problems may arise with the operation of the iPhone or iPad. A software failure can lead to the failure of the iOS device, and it will be possible to return it to a healthy state only by flashing it.
Also, recovery may be necessary if the user forgot the unlock code for iPhone or iPad. Resetting the device to its original state, the password will be removed from it.
Another reason for flashing the iPhone may be the planned sale of the device. In order for the buyer to receive the smartphone new at the factory settings and without the data of the former owner, you can perform its restoration.
Important Apple Device Recovery Rules
The recovery process for iPhone and iPad can only be performed using a computer using iTunes.
Apple does not permit the installation of an iOS version on the device other than the installed version. This rule has an exception, which has received the name "Time Window" among users. Under this concept, a period of two weeks is determined (in some situations it changes) after updating the firmware, during which the user can "roll back" the version of iOS to the previous one.
Important: This rule does not apply to beta versions of iOS firmware. If a test version of the software is installed, at any time the owner of the device has the right through iTunes to restore it to the latest official version of the firmware.
