What you did in interfaces file? I use the change mac address tweak. This lines are from my interfaces file:

auto eth0
iface eth0 inet dhcp
hwaddress ether 00:13:8F:4F:6B:D8

first there were code:
..................................................
auto eth0
iface l0 inet loopback
hwaddress ether 00:1:....( mac adress i changed)
..................................................
then i chancged like u with my mac adress
but still take the same mac of the device

How about right-clicking on the icon of network manager and then "Edit connections"?

I tried left click and edit connections but that did not work for me
