adb and fastboot command What is the difference

ADB Chinese explanation is the role of commissioning of the bridge. Since it is a commissioning role, you need to boot and connected to the computer, so the phone adb command is required to open usb debugging, typically a command such as typing adb commands from the computer Bryan application: adb install. There is also a command we often use (or borrow some software to use, but you do not know) that adb reboot bootloader, this command is to achieve control of the mobile phone or device from the computer to enter bootloader mode, but it is fastboot work in our so-called line of this pattern brushes are actually working in bootloader mode.
　　The reason why we confusing because generally when we install the driver, adb and fastboot drivers are installed by default together, and then, Brush tool beginning we ask you to open usb debugging, then brush machine process called adb reboot bootloader put the device into the bootloader mode, after all gone fastboot command, which makes a lot of veterans are considered adb solve it all, or that the brush must be open usb debugging (many users complain, I can not get into the system, forgetting to open usb debugging, how brush? read this article you should understand that it is time to abandon those tools up). actually not.
　　In short, need to open usb debugging command to work or operations are related adb, enter bootloader fastboot mode to work is related to the two are different commands, you need to install a different drive, you do not need to complete the work Brush any adb command to complete, there is no need to open usb debugging, and some students may ask that the total need adb to unlock it, do not need to, because those are unlocking tool called adb reboot bootloader, then call fastboot oem unlock to unlock , of course, those locked bootloader encryption is invalid.
