I am unable to enter fastboot mode. I have tried all the adb commands and holding the buttons but it just reboots like normal. I have Allow OEM Unlock activated in Developer Options why won't it work?

After messing around with my shield last night and not being able to get root access on cm12. I tried to reinstall one of the ota updates from a while back. Now I am bootlooping and when I try to boot into CWM it looks to be corrupted and doesn't load. I cant use ADB because usb debugging is no longer active. Does anybody have any suggestions to re-install recovery or somehow enable debugging or am I dead in the water here? Any help would be greatly appreciated
Is your bootloader unlocked?
Can you get into fastboot mode?
HW method:
Turn off the device
Press and hold "Back"+"Home"+"SHIELD" buttons till device boots

If you can get into fastboot mode and your bootloader is unlocked, you can use a command like "fastboot boot recovery.img" to have the device boot a recovery.img from your computer without flashing anything.
If you can get into fastboot mode, but your bootloader isn't unlocked you could try unlocking your bootloader, but this will wipe your data - so only try this if you don't have anything important saved. The command is "fastboot oem unlock".

The bootloader is unlocked Whenever I try fastboot mode the device is not recognized because USB debugging is disabled .
Update: Fixed
I am in the process of rooting my phone and have already unlocked the phone but for some reason I am unable to boot into the bootloader. I have a MT7-CL00 and I have tried pressing the buttons on the phone, but every time I go into the normal boot mode.
I have USB debugging activated and I am able to connect with ADB / Fastboot and when I type ADB devices my device is shown as active.
When I type fastboot reboot I just get a message < waiting for any device >
Have I some now turned off the bootloader booting method on my phone?
Is there an alternate way to trigger the phone to boot into the bootloader?
Thanks!
Type adb reboot bootloader
Then fastboot devices, if it detects run further desired fasboot commands.

Bought this device and everything works great and I have root. When I try to unlock the boot loader by going to "Developer Options" and checking the "Oem Unlock", I then
Code:
adb reboot-bootloader
At this point I do a
Code:
fastboot oem unlock
Which then the device asks me to use the volume buttons to confirm, Volume up for yes and volume down for no. The problem I'm running into is in fastboot mode it seems my volume up and power key are completely ignored. They work in recovery and in android but not in the boot loader itself.
I have tried unplugging the phone after sending the command over to see if that is a factor but it doesn't seem so. I'm only allowed to use volume down which denies unlocking the boot loader.
Another thing if anybody can get me a scatter file that would be much appreciated.

How did you root the phone?
Hoping for an answer to the bootloader question as well. For root I'm going to attempt kingoroot and replace with supersu

@Tab E mercy but i can^t exit out of the fastbood mode to chagne the settings i`m locked inside this bootloader mode and cant do anything else but try with fastboot oem unlock...
Try
Code:
fastboot devices
fastboot reboot
@jwoegerbauer the commands work the oneplus is rebooting into the fastbood mode again i need to exit the fastbood mode because maybe the os deleted and can only use fastboot mode to flash it or else i dont know how to exit the fastboot.
I don`t know if developer mode is on or if oem lock is unlocked but since i cannot go back into the oss of the system what can i do to recover the device completely
i`m stuck in this fastboot mode and no commaand is helping to get out of it what is the solution_maybe to take out the battery it is really hard have you had the same issues?
Whether phone should run in ADB mode or Fastboot mode or Recovery mode or ADB Sideload mode is set via a kernel flag read by bootloader when phone boots up. Pulling out phone's battery doesn't change this flag.
Typically to boot Android in NORMAL mode you run
Code:
adb devices
adb reboot
Hello! I was messing around with key combinations, and I found that in the default android recovery on this phone, you can enter a Fastboot mode, and ignore the download mode that samsung phones traditionally use. I can't seem to get it to communicate with my computer, and I was wondering if it would be of any use to unlocking the bootloader on this device.
Fastboot mode is a way to unlock the bootloader.
Download mode and fastboot would be the same thing
fastboot oem unlock does this same thing
It would be nice for a picture though.
