Apple is divided into two recovery modes, one is called DFU mode and the other is recovery mode. The full name of DFU is Development FirmwareUpgrade, which actually means the forced upgrade mode of iPhone firmware. In recovery mode, iTunes and cable icons will be displayed on the screen.

The two biggest differences are that the DFU mode does not boot the Mac OS system, iTunes can't decide whether the recovery process of your iPhone is interrupted or not, because the system doesn't boot and the related services can't be enabled. In general, if the device has a software failure and cannot start normally, it can be solved by this method. Specific steps:

1. Enter the detailed steps of DFU. Note: Be sure to connect the data cable with the computer when entering the DFU operation.

1. Press and hold the power switch for 3 seconds.

2. When you press power+home, the screen turns black and you read silently for about 10 seconds.

3. Let go of the power on-off key, keep the home keyboard for more than 10 seconds, and you can also use it for a long time, but the screen is black.

When you release all the buttons, the screen goes completely black and you will enter DFU mode. At this time, opening iTunes will prompt you to restore your phone.

If you don't have a good grasp of the time, it is recommended that novices use the Red Snow tool to enter DFU mode, which can be operated according to the prompts.

During the process, the iPhone screen will show ** walking.

Wait patiently for the progress bar to finish, and when the prompt is completed, you have successfully entered DFU mode.

1. First of all, disconnect the data cable. Turn off your iPhone2, after shutting down, press and hold the home button to hold still, connect the data cable to the computer, and release the home button.

3. Exit recovery mode. The method is very simple, press and hold the home button + power button at the same time until the white apple logo appears on the screen.
