There's a critical bug 
(https://bugs.launchpad.net/canonical-devices-system-image/+bug/1551150) 
that makes devel-proposed failed to boot.

I recommend you to reflash your phone to stable or rc-proposed using 
instruction you linked above in recovery mode. But, as I don't have 
Meizu MX4, I don't know if it's recovery image have ADB enabled or not. 
If it doesn't (and it likely doesn't), then you'll have to find recovery 
image that have it enabled. I don't know where is it, but I've heard 
people in this list talks about that at least once. When you have that, 
you'll have to flash your phone in fastboot mode using --bootstrap and 
--recovery-image flag with ubuntu-device-flash. Beware that this will 
wipe all data on the phone.

Good luck,
Ratchanan Srirattanamet.
