YOUR PHONE DATA MIGHT BE DELETED DURING THIS PROCESS, SO MAKE SURE TO HAVE A BACKUP BEFORE YOU UNLOCK BOOTLOADER ON YOUR MEDIATEK PHONE.
I CANNOT BE HELD RESPONSIBLE IN ANYWAY FOR THE MISTAKES DONE BY YOU.
Why to Unlock Bootloader on the Mediatek Device
Most of the Android phone manufacturers now a days lock the bootloader, so as to prevent modification of the stock firmware or software that is installed on the Android phone regardless of Mediatek chipset based or other.
A bootloader is a software code that runs when an Android phone is powered up, whose job is to load the boot image then rest of the software will be loaded by the boot image.
So, when you are powering up the phone 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.
What you can do after Unlocking Bootloader on Mediatek phone
Well, after unlocking the bootloader, you are free to flash or install any bootable image you want to.
But still it is not easy. You cannot just install anything into it.
Every Android phone has a recovery mode which is usually used to recover the Android phone if the phone software has gone bad or to reset phone to factory mode etc.
To be able to alter the stock Android software or to install any other Android Custom ROM to your Mediatek phone you need to first install a custom recovery image.
TWRP is a popular custom recovery available for many or almost all Android phones out there.
After installing the TWRP recovery to your Mediatek phone you can ROOT your phone, install LineageOS, or any other custom ROM or you can install mods, etc.

Hi, I’ve got an issue with my bootloader, which seems to sit at showing “Fastboost mode =>” only.
If I write anything into CMD, such as fastboot oem device-info, It just shows “…” forever on. Seems to happen after writing any line with OEM in it.
What am I doing wrong?February 19, 2019 at 6:19 AM #73046
I think it is a problem with the fastboot USB drivers.
