What is Fastboot Mode?

Fastboot Mode on the OnePlus 8/8 Pro is an interface that enables communication between the phone’s bootloader and a PC over USB, using the Android Fastboot tool.

When it comes to practicality, Fastboot mode can be used to unlock the bootloader, flash the device partitions for upgrading/downgrading the software, for unbricking, and even for installing a custom recovery such as TWRP or flashing patched boot images for rooting.

What is Recovery Mode?

OnePlus 8 (Pro) Stock Recovery Mode

Recovery Mode is a bootable partition in Android where the stock recovery (OxygenOS recovery) is pre-installed by the manufacturer (OnePlus).

Recovery Mode on your OnePlus 8/8 Pro can be used to perform a variety of tasks to recover the phone from a bootloop or to fix software-related issues. These tasks include performing a factory data reset, sideloading software updates, and more. In case you have a custom recovery installed instead of the stock recovery, you could use it to install custom ROMs/kernels/mods, take NANDroid backups, format/erase partitions, flash root solutions like Magisk, and more.
