Why did you encounter wait for device when you use fastboot to brush the machine?

I met. I have searched for countless methods on the Internet. I have told you that the driver is not correctly installed, ADB is not deleted, and I have tried none.

If the driver is not correctly installed, I have also tried it on Linux, and there is no need to install the driver on Linux. No. (Fastboot should be used for Linux and Linux)

Later, after numerous experiments, I finally tried my methods.

The reason why your fastboot has always been wait for device is that you have used an inappropriate fastboot.

The correct fastboot meets the correct USB driver, which is a lifetime of happiness...

Fastboot encounters an inappropriate USB driver and will only be waiting...

There are many versions of fastboot on the Internet. Don't think they are named fastboot, fastboot-windows, or fastboot-window. You just think they are all the same. You can use either of them. It must be compatible with your USB driver.

I have used practical experience to tell you that when I change countless drivers (the drivers are called android_winusb.inf and cannot be deleted after reinstalling), I still cannot. Finally, I downloaded a lot of fastboot from various places, including from my company. I have at least 20 fastboot instances on my computer. I tried it one by one, and 9 of the 20 showed wait for device. However, there is a fastboot. When I input the "fastboot devices" command, it displays my device correctly (my device is a development board, actually, it's the same as a mobile phone )!!! My God! I found it!

Then, after countless combined trials, I installed the drivers downloaded from different locations and used them separately with fastboot. Finally, only the fastboot can display my device. All others are wait for device. No matter what version of the driver is installed.

Finally, I came to the conclusion that most of the posts on the Internet are nonsense. It is the truth to try fastboot several more times. Persistence is victory! I hope that my friends who have encountered this problem can solve this problem smoothly.
