Unlocking Bootloader Android 7.1.2 I have a RCA device running Android 7.1.2. I'm having difficulty unlocking the bootloader.

On my device I've an option to turn on OEM Unlocking. When I try it asks if I want to enable when I select Enable it just jumps back to off position.

This is what I have tried.
adb reboot fastboot
The device reboots and stays on the splash screen when I do fastboot devices it shows "0123456789 fastboot". This seems weird to me I expected to see the S/N number like I see when I do adb devices.
Then I tried "fastboot flashing unlock" I don't see any change on the device and I instantly get FAILED.



How can I get the bootloader unlocked?

I have seen people that have gotten it unlocked, but they were on a previous version of Android.

My tablets info:

Enable OEM Unlocking
If your devices manufacturer allows OEM unlocking
A.K.A (Also Known As) "Bootloader Unlocking".







After Enabling OEM Unlocking    


Reboot to Fastboot   

ADB


adb reboot bootloader

OEM Unlock   


fastboot oem unlock
or
fastboot oem unlock -go
or
fastboot oem unlock /path/to/unlock-token.bin    



If you have an MTK CPU you might be interested in flashing image's using a scatter file and SP Flash Tool v5.16 or above, as it doesn't require an unlocked bootloader.
