can i downgrade kazam trooper 551 from 5.0 to 4.4

[bazza1306]

I have a new kazam trooper 551. It comes with 5.0 on it however i have only got it to run a certain app and the app will not run on 5 and above. Would it be possible to put 4.4 onto the phone. Hope someone can help thanks. p.s i also have a wileyfox cyanogen 6.01 if i could downgrade that but assumed that would be too much of a downgrade
