For example, Apple's mobile phone brushing tool is iTunes, and Xiaomi's is Xiaomi's mobile phone toolkit. Tools from different manufacturers may be different, depending on whether the government provides them. Generally, it can be found in official website or some popular mobile phone forums.

The second point: you need a software package for brushing machine.

The software package is like the operating system version of a computer. For example, Apple's current version is 8.3, and Xiaomi's current MIUI version is MIUI 6. Different versions correspond to different software packages, some can be downloaded in advance, and some can provide download function at the same time.

The third point: you need to know how to enter the brush mode.

Brush mode or engineering mode is like a supermarket. As a customer, what you see is one scene, and what the supermarket staff see when they enter the warehouse is another.

For example, when Apple's mobile phone enters the refresh mode, it is connected to the computer with a data cable when it is turned on. First press and hold the power off button for 2 seconds, then press and hold the power off button and the Home button at the same time for 8- 10 seconds. Finally, just press and hold the Home key 15 seconds to enter the refresh mode.

Xiaomi's mobile phone is turned off to enter the brush mode, and at the same time, press and hold the volume down+power button to enter the brush mode.

Different mobile phones and different models may be different, and specific operation methods can generally be found.

What should I pay attention to?

Pay attention to make the machine have enough power before brushing, and don't interrupt during brushing. In addition, the brush will lose all the data of the mobile phone.

The general operation steps are as follows:

In fact, the operation steps themselves are relatively simple, much simpler than installing a computer, and some details are easy to make mistakes, such as the connection failure between the mobile phone and the brush machine, which is related to the development of software, drivers and brush machine tools on the computer.

The general steps are to install the brush tool software, run the brush tool software, and the tool software prompts to connect the mobile phone, and then the operation enters the mobile phone brush mode. Then the tool software selects the software package version that needs to be refreshed. If there is no accident, the screen of the mobile phone is moving when the machine is swiped. After the normal progress is completed, the phone is refreshed and the phone is used normally after restarting. Because of data transmission and other problems, the brush machine may fail, and you can try it many times. (Some swiping refers to the process that the mobile phone can enter normally, then save the swiping package in the memory card, and then the mobile phone enters the swiping mode and reads the swiping package by itself. )
