Please do not use u-d-f on production MX4 with Flyme. Even if your phone is
unlocked, Ubuntu installation will fail.
If you have MX4 with Flyme, you will need to use MTK flash tool to
repartition phone in order to install Ubuntu. Flyme has partition table
incompatible with Ubuntu requirements, so even if by some magic you manage
to flash Ubuntu recovery to kick off Ubuntu installation, it will
eventually fail with out of disk space error. u-d-f --bootstrap works on
Nexus devices where it's using compatibility mode, since we have no option
to repartition those phones, also idea of developer previews on Nexus
phones was to give developers option to switch back to Android....

Also having ability to boot to bootloader does not necessary mean your
bootloader is unlocked. You can refer to Google Nexus devices, where you
need to run oem unlock to unlock bootloader, which wipes user data.
Otherwise this would open big backdoor to otherwise secured phones. (Flash
custom recovery and get all users data from stolen phones....)
cheers
