I'm trying to unlock the bootloader of my OnePlus 6 so I can root but my laptop can't recognise my OnePlus in cmd prompt. I tried uninstalling and reinstalling the drivers and even a rooting tool that I got from XDA and nothing is working, can someone help me? (I'm fairly new to rooting)

See if you can find your device in Device Manager. If it has an yellow triangle on it you need to install adb drivers for it.

Did you both checked "allow USB debugging" under developer options and actually allowed it after connecting to USB port, it it didn't appear on your phone?

As mentioned, make sure you've enabled Developer Options, then through there, enable OEM unlocking and USB debugging. Is the phone booted into fastboot mode (bootloader) when you're trying to find it via the command line? If you're booted into the system, fastboot won't work. Only adb will.

Another thing that might help is to use a Mac if you have access to one. There's no need for drivers, so that problem is eliminated. Connect via USB and the command line should work. (This is not a PC vs. Mac thing; it's just a practical matter.)

Solution

I had the same issue and the solution for me was to reinstall oneplus drivers the updated ones from the oneplus drive that appears when you connect the device.

-Download latest OP6 drivers
-Enable Developer Options
-Enable USB debugging in developer options

When the phone is booted, you can use ADB devices commands, however, when in the bootloader, you'll probably have to use Fastboot devices.

On my phone, ADB devices never works at the bootloader, only outside of the bootloader.

I had an issue where every time I wanted to connect to fastboot, I had to turn off USB debugging, plug into my computer, wait for it to recognize, unplug, enable USB debugging, and reconnect to PC. Might be worth a shot to see if it's the same issue.

Doing this and enabling test mode on W10 LTSB before reinstalling the official OnePlus drivers worked on my OP5T (OOS 9.0.5). I had the same issue the OP described.
