Some points to pay attention to when brushing the machine

1. As long as the computer is connected, you can brush it yourself whether it is normal use or white screen. If the phone is not connected to the computer (such as a black screen), then you can't brush it well.

2. Ordinary data cable can't be brushed, only pictures and MP3 can be transmitted.

It is very important to ensure that the battery of the mobile phone is over half when brushing the machine.

Please read the operating instructions carefully before brushing your teeth.

Don't put the fourth gear (or the third gear) in the wrong position when brushing the machine.

6. It is recommended to brush the DIY version with the same serial number on the basis of the original mobile phone (if this version will change the serial number, most people still don't brush it, otherwise it will be difficult for them to solve this kind of problem.

Several problems of scrubbing machine

1, not all mobile phones can swipe their cards. For example, Nokia's brush machine needs a special brush box, so you can't brush it yourself. So I can only go to customer service and some mobile phone manufacturers to brush the machine.

2. Not all problems can be solved by brushing. Some problems may be hardware problems, so don't rely too much on the brush machine.

3. It is best to brush the machine under the premise of controllable risks. The current DIY versions are based on the original version, but the original picture is replaced by another picture, and the original ringtone is replaced by another ringtone, without moving the core part. It's just that some pictures, ringtones or menu characters have been replaced or changed, which should not have any adverse effects ~ As long as you make a backup of the mobile phone software and follow the steps, there is basically no risk in brushing the machine (if you have to brush it back).
