I'm trying to unlock the bootloader on my LG G6 (specifically LGUS997) phone to enable root access. Following LG's instructions, I've downloaded the command line Android SDK tools, notably ADB and fastboot.
ADB recognizes my phone just fine but in order to unlock the bootloader I need to reboot the phone into fastboot mode (which ADB can do). The problem is fastboot.exe does not recognize my phone at all, even after installing the Google USB drivers as well as my phone's specific drivers.
All of the solutions I've found online are to install the drivers I've already installed, or to enable USB debugging (which I have done).
For clarification, I'm using 64-bit Windows 10.
