i also have the A56 ....... i also have the same problem
i am going to try a new way of doing it next weekend as i am having my exams
if you want , you can try this and give me the results -
A quick tutorial to ROOT Micromax A50 Ninja - xda-developers
this is for the A50, but if we can somehow make it work for the A56 it would be great !!!!!
Best of luck !!!!
