Many of the Android phone companies nowadays lock the bootloader, so as to limit the change of the stock firmware or software that is pre-installed on the Android phone regardless of Mediatek chipset based or other.

What is Bootloader:

A bootloader is a software code that runs when an Android phone is powered up, whose job is to load the boot image then the rest of the software will be loaded by the boot image.

So, when you are powering up the Cube U27GT Super Edition or entering into recovery mode, there is a boot kernel that is loaded by the bootloader to memory to execute. The bootloader is locked to make sure the bootable image always remains the same and cannot be altered.

To be able to alter or modify the bootable image to be loaded by the bootloader, you need to unlock the bootloader.

The Advantage of Cube U27GT Super Edition

once unlocking the bootloader, you might be able to flash or put in any bootable image you would like to.
But still, it can be hard. You cannot simply install anything in it.

Each Android phone includes a recovery mode that is generally used to restore the Android phone if the phone software went bad and to reset the phone to factory setting etc.
In order to alter the stock Android software or to install another Android Custom ROM to your Mediatek phone, you have to initially install a custom recovery image.

TWRP is a superb custom recovery designed for many or nearly all Android phones out there.
After installing the TWRP recovery in your Mediatek phone you are able to ROOT your phone, install LineageOS, or any other custom ROM you can also install mods, and so on.
