Hidden fastboot mode or no fastboot at all? So here is my problem: I cant get in to fastboot mode on my lg k8 us375 android m 6.0. 

Here is what I'm doing: 


adb and fastboot are installed on pc (windows)
I have developer options and OEM bootloader unlock enabled 
In terminal adb devices shows my phone 
I enter adb reboot-bootloader but it does not say "fastboot mode" on screen like I have read it is supposed to. It just restarts my phone. 
( note I have tried variations like reboot_bootloader; same result ) 


So my question is am I doing it wrong or is fastboot not on this phone. Or is it hidden somehow?
To go in Fastboot mode: 
- Switch off the phone
- Hold Volume down button
- While holding down the button, connect the USB cable to the phone (assuming the cable is already connected to the computer)
The phone should go in the Fastboot mode. 
In the command prompt, tape fastboot devices , you should see xxxxxxxxxxx device as feedback.
Drivers must be installed as well.
Hope this will help.
