You just ordered OnePlus 6 and want to learn How to enter fastboot mode/bootloader mode on OnePlus 6 to make some tweaks or modify it later on. Every Android-based smartphone has some fastboot mode that requires a properly configured computer to flash system files on it. Popular uses of fastboot mode include installing the official firmware, custom ROMs and custom recoveries on OnePlus 6.

If you are not a technical person you should know you don’t have to install fastboot, it is a built-in feature on your OnePlus 6. For those who are worried about warranty, you should be aware of simply accessing bootloader and even flashing official software will not void it.

In case your OnePlus 6 is not detected by computer at all, all you need to do is to install OnePlus 6 USB drivers.

What is Fastboot Mode?

Fastboot is a tool/protocol for writing data directly to your phone’s flash memory. In practical use, it is used to flash images such as recoveries, bootloaders, and kernels to your Android device. Outside of the obvious, you can also restore android backups, change your splash screen, and flash system updates.

With Fastboot, you can easily flash certain parts of or a full system. There are vital parts of Android OS, the modem, bootloader, and system. These parts can be upgraded or changed manually via a computer that recognizes the phone and has the Fastboot software.

Other than installing/upgrading firmware, fastboot is not of much use. Except there is a trick that allows you access other system modes on OnePlus devices, but for that, you need to have access to Fastboot.
