No... There is no "magic" or anything else... If OEM unlocking is not turned on, then you cannot unlock the bootloader.

Nexus 5X Stuck on fastboot mode, won't open up recovery mode

Hi pals,
My excuses if this sort of problem that I post (English is not my native language, so I am sorry for any spelling mistakes), is already posted earlier.
My Nexus 5X is currently stuck on Fastboot mode with the following specifications:
FASTBOOT MODE
PRODUCT_NAME - bullhead
VARIANT - bullhead LGH791 32GB
HW VERSION - rev_1.0
BOOTLOADER VERSION - BHZ11m
BASEBAND VERSION - M8994F-2.6.37.2.21
CARRIER INFO - N/A
SERIAL NUMBER - 00ce1aff0bcc3ea6
SIGNING - production
SECURE BOOT - enabled
DEVICE STATE - unlocked
As you can see, I already unlocked my bootloader with help from the Nexus Root Toolkit. My device is currently in Fastboot mode. The working functions are Restart bootloader and Power Off. Neither Recovery mode and / or Start.
But I can root my Device with help from Nexus Root Toolkit.. When I do that, a TRWP warning pops up, and it says that I don't currently have a OS on my device and that I sure want to do this.
So, my questions now are:
-How can I get to the original OS?
-How to unroot my device?
Edit 1: After I chose the option 'Flash Stock + Unroot' on the Nexus Root Toolkit program, my device is now stuck on the Google logo with a unlocked bootloader, after everything is finished in the Command Prompt.
Any help would be appreciated.
Thanks in advance!
Update 1: I chose the OEM Lock option in the Nexus Root Toolkit program, and I don't have a unlocked bootloader anymore by startup. But my device is still stuck at the Google screen... I created a AB backup before I wanted to root my device, should I apply that backup now to my device?
Best way to fix it is to post in NEXUS 5X FORUM! btw i think its emmc failure, as many 5x got this..

Can't enter fastboot mode after unlocked

I have unlocked my Huawei tablet using
Code:
oem shell
-> reboot fastboot
and later in fastboot mode:
Code:
fastboot oem unlock <pw>
now each time I am trying to enter the fastboot mode I get the
nasty "Your device has been unlocked and can't be trusted"
and throw me back to the regular boot.
Any idea what else I can try?
Code:
The info of my model is:
Named: Huawei M3 Youth
Model: CPN-AL00
Firmware: : MSM8940C00B056SP01M_AMSSJun28201718:26:30
Hardware ver: : SH1CHOPINAL0M-V2

Thanks for the reply but nop in HuaWei the gicky stuff comes with volume up button but in that case the
same thing I get the ugly text message and normal boot :/
Any other ideas?
Found it: you really hold the volume down and just plug the USB cable no other
actions required, it will turn on into the fastboot mode.
i have a insignia with same problem get nasty mess. bootloader error code 3 but can not get to boot to fastboot mode only factory recovery . in factory recovery mode i select reboot to bootloader and if just restarts again with same bootloader mess. error code 3

Please could you tell me if your device is able to boot to system ?
If so
Please open settings and go to about phone option. Tap build number few times until you get a message you are now a developer.
Once done, navigate back to system settings and enable oem unlock and usb debugging option. if not you need to manually flash OOS from boot loader.

Please try flashing recovery using the below command.
fastboot boot xxxxx.img
xxxxx.img is the recovery file name you download .
Please download the recovery img and zip files from the forum . If that doesn't work please let me know.

Enable Oem unlocking in developer options
@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
