This article is to share with you what is the dfu model, the editor thinks it is very practical, so I share it with you to learn. I hope you can get something after reading this article.

Dfu mode is a kind of Apple recovery model, which actually means the forced upgrade and downgrade mode of iPhone firmware, while the recovery mode is the mark of itunes and data graph displayed on the screen.

This article operating environment: Windows7 system, Dell G3 computer.

1. Apple has two recovery models, one is called DFU mode, and the other is recovery mode. The full name of DFU is DevelopmentFirmwareUpgrade, which actually means the forced upgrade and downgrade mode of iPhone firmware. In the recovery model, itunes and cable icons are displayed on the screen.

2. The biggest difference between the two is that the MACOS system is not started in DFU mode, and itunes cannot determine whether the recovery process of iPhone is interrupted, because the system is not started and related services cannot be enabled. It is said that the iPhone recovered in DFU mode is more thorough.

3, in general, such as our equipment software failure, can not start normally, such as our device boot password forgotten, as well as the legendary white apple, and so on, can be solved through this method. That's why I called him an invincible rebrush mode.

Tutorial:

1. Enter the detailed steps of DFU. (after entering successfully, the screen is all black) Note: be sure to connect the data cable with the computer when entering the DFU operation.

2. Hold down the power switch for 3 seconds.

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

4, release the power key, keep the home keyboard for more than 10 seconds, or a little longer, the screen is black and the screen is all black after releasing all the keys and then enters dfu mode. At this time, opening itunes will prompt you to restore the phone. If the time is not good, it is recommended that the novice use the Red Snow tool to enter dfu mode, which can be done according to the prompt. Click to download Red Snow to open the Red Snow tool, select "other", as shown in the picture to enter DFU. During the operation according to the Chinese prompt, the iPhone screen will show the code to move patiently and wait for the progress bar to finish. When the prompt is completed, it has successfully entered DFU mode.

5. The method of recovery

6. First of all, disconnect the data cable and shut down the iPhone. 7. After shutting down, press and hold the home key to keep still, connect the data cable to the computer, release the home key, and the screen prompt as shown in the figure icon, the recovery mode will enter successfully. When you connect to itunes, you will also be prompted to enter recovery mode.

8. Come out of the recovery model. The method is very simple, and hold down the home key + power key until a white Apple LOGO appears on the screen.

The above is what the dfu mode is, and the editor believes that there are some knowledge points that we may see or use in our daily work. I hope you can learn more from this article. For more details, please follow the industry information channel.
