Apple 6 I don t want my current system, can I restore the factory system?

No, you can only delete the apps and ** inside.

1. If your iPhone has been jailbroken, please don't use this method to reset it. First, look for the Settings app on the screen and start here.

2. Find the "General" option in the settings list and click to enter.

3. Then find the "Restore" option in the general list, which is located at the bottom of the list.

4. Then you can see that there are multiple restore options in the restore list, such as restoring all settings, restoring the network, restoring the home screen and other options. Here are the three restore options:

Reset All Settings: This feature can restore all settings on your iPhone without data loss;

Erase All Content and Settings: This option is the "Reset" feature mentioned here, and once you do it, all the data on your phone will be gone.

Reset Network Settings: This option is used to reset only the network, and will not affect other settings and data;

If you want to reset your iPhone completely, you can select the "Erase All Content and Settings" option.

The current iPhone and iPad cannot be downgraded after upgrading.

The explanation given by Apple is as follows:

iOS adopts a recommended upgrade and enforces the latest upgrade policy, and once upgraded, it is impossible to downgrade.

It is mandatory to maintain the latest system version to prevent information leakage to users due to vulnerabilities in earlier versions.

Apple has launched the ID lock since iOS7, and the prohibition of downgrade is to prevent someone from stealing and reusing it through the downgrade method, which can effectively reduce the theft rate of iPhone and iPad.

Apple's system can only be upgraded, not downgraded.

Factory reset can only delete all data in the phone (including text messages, **, songs, programs, etc.).

Yes, but you need to make a SHH backup of your system in advance, and you cannot restore it if you don't have a backup.

After backing up shsh, perform the following steps:

No, a factory reset will erase the phone's settings and some files and restore them to the initial state. Choose to erase all content and settings to return to a pure state of the system, of course, the system version will not change, it is impossible for ios8 to be restored to ios7
