uses iOS update archives provided on Apple servers for their over-the-air update feature.
These files are usually around ~ 2GB in size. butCydia Impactor
minimizes the cost of traffic by downloading only the files you need.
Most standard restorations will not spend more than 10MB of traffic.
First, the "bill of materials" process takes place in which a list of modified files is generated.
Further, all files that have been modified or destroyed will be downloaded directly from Apple.
There is a "neat" file transfer.
All new files will be copied to the user section.
Then all system data will be copied back to the system partition.
The idea is that no "unsafe" changes in the system have been made and ifCydia Impactor
will fall \ will give an error or the device will reboot, you can always try to start it at any time later.
When all files in the system are changed and returned to stock status,ALL OTHER DATA WILL BE DELETED
, and iOS will be launched in the "Erase content and settings" mode.
That same вЂњcritical pointвЂќ lasts only a few seconds at the end of the tweak process.
The process may take longer if you had a lot of space for user data.
Do not touch the device during this process.
When the device reboots, it will look like it was turned on for the first time.
It will no longer be jailbroken.If you need a jailbreak, re-perform the hacking procedure using a PC utility.
