1. Restore from Time Machine
1. If you want to restore the system from Time Machine, you need to meet two conditions:
1. Before the problem occurred, use Time Machine to back up the Mac OS system;
2. The current Mac system can enter Recovery disk mode;
As long as the above two conditions can be met, this method can be adopted
When starting your Mac computer, you can hold down the Option key to choose to boot from the recovery disk, or hold down the Command R key to enter recovery disk mode.
3. Then select the "Restore from Time Machine backup" option
In this step, you can insert the Time Machine device that was previously backed up on other storage devices, such as the backup I previously backed up on a mobile hard drive. Then, click on the "Continue" button to proceed to the next step.
5. Next, the computer will automatically find our backup file, click the "Continue" button
6. You will then see the date of the backup file, select one and click the "Continue" button
1. Enter DFU mode
2. Link to itunes

About how to enter DFU mode, as follows:
The first method is normal recovery
This recovery method is the most commonly used method to restore iPhone firmware in our general unlocking tutorials.
1. Connect the iPhone to the computer, then shut down the iPhone
2. Press and hold the power button and home button at the same time
3. When you see the white Apple logo, please release the power button and continue to hold the home button.
4. Open iTunes, wait for it to prompt you to enter recovery mode, then hold down the shift key on the keyboard, click "Restore", and select the corresponding firmware to restore.
Second method: Black screen recovery
1. Connect the iPhone to the computer using a USB cable, and then you will hear a sound prompt that the computer has been connected successfully.
2. Now please turn off your iPhone first, and then you will hear the prompt sound that the computer has not connected successfully.
3. Please press and hold the power button and home button at the same time until the 10th second. Please release the power button immediately and continue to hold the home button.
4. At this time, iTunes will automatically start and prompt you to enter recovery mode (the iPhone will remain black screen). Then you can hold down the shift key on the keyboard, click "Restore", and select the corresponding firmware to restore.
First make sure your iPhone is connected to the computer via a USB cable and iTunes is closed.
If your phone is on at this time, please turn it off first. Press and hold the power button, and when the shutdown option appears, slide to shut down.
Then please press the power button to turn on the phone. The Apple logo will appear on the screen, but do not release the power button.
At this time, please press and hold the Home button again until the screen goes black.
When the screen goes black, please release the power button and continue to hold down the Home button until iTunes on the computer detects an iPhone in recovery mode.
Finally, we can hold down the "shift" key on the keyboard, click the "Restore iPhone" button, and select the iOS firmware system to be restored to restore our iPhone,
Note: If you are restoring the iOS 7 beta firmware, please press and hold the "shift" key on the keyboard, and then click the "Check for Updates" button. Since my machine is already on iOS 7, the "Check for Updates" button in iTunes is unavailable.
