How to Fix OnePlus Device not showing in Fastboot Mode

Enable USB Debugging
Next up, you will have to enable USB Debugging. This will make your device recognizable by the PC in ADB mode, which will then allow you to boot your device to Fastboot Mode. So head over to Settings > About Phone > Tap on Build Number 7 times > Go back to Settings > System > Advanced > Developer Options > Enable USB Debugging.
Connect OnePlus to PC
Now connect your device to the PC via USB cable. If this is the first time, then you should see the CD Drive: OnePlus Drivers option. Open it and install the associated drivers.
