Help fastboot command

[Android Question]

How would I use the command fastboot getvar all? Does this require a computer or can it be used on the phone? What is fastboot?

Welcome to our AndroidForums .

The fastboot utility does indeed require a PC.

It also typically requires specific USB drivers if you're using a Windows PC (Linux / Mac is a bit easier, but likely requires using sudo).

It also requires that your device is booted into what is called fastboot or bootloader mode (some a small number of (stubborn) devices that won't even show you the bootloader screen).

fastboot is a utility for interacting with the bootloader to do device-specific things (checking the bootloader lock state, flashing the boot or recovery partitions, etc.).

The functionality does vary by device and whether or not the bootloader is unlocked, though.
