A recovery mode restoration is the next suggested approach for serious software issues that could not be resolved by a factory reset. Through iTunes, you may clean, restore, and recover iOS. To get started, make sure you have the most recent version of iTunes installed on your computer. Then, using the Lightning cord, connect your iPhone to your computer. Once connected, follow these instructions to enter recovery mode and then restore iOS in iTunes:

1. Quickly press and release the Volume Up button.
2. Then, swiftly push and release the Volume Down button.
3. Finally, hold down the Power/Side button until you get the Recovery Mode screen. When the Apple logo shows, don't let go of the button since you need to get into recovery mode.
4. Wait for the Restore or Update prompt to appear when you see the recovery mode or Connect to iTunes screen. Then choose Restore from the drop-down menu.
5. Wait until your iPhone's system has been restored before continuing with the remainder of the instructions onscreen.
