Fastboot mode is a protocol or diagnostic tool that is part of the Android SDK Platform Tools collection. It is a boot mode that allows you to modify or write data directly to your phones flash memory. Fastboot mode is an alternative to the recovery mode that helps with installations and updates. It is a mode that loads independently of the operating system and allows you to flash various files on your device. Fastboot mode gives you access to your devices partitions, the data partition, and the boot partition. Manufacturers often lock these files for safety purposes, but if your manufacturer has allowed the bootloader to be unlocked, you can do fastboot your Android device with fastboot.
To enter fastboot mode, you need to press a specific combination of buttons on your device while it is turned off. Once you enter fastboot mode, you can use fastboot commands to perform various tasks on your device from your computer. These tasks include flashing custom recoveries, stock recoveries, custom ROMs, and other modifications. Fastboot commands work only when the phone is entered into fastboot mode.
If you are satisfied with your Android phone and do not want to perform any significant modifications to it, then you probably do not need fastboot mode. However, if you want to modify certain parts of your phones essential files, fastboot mode can be useful. If your device is stuck in fastboot mode, you can follow specific steps to exit it.
