Unhappy Root Problem on Micromax A120

My Device is Micromax A120.
I've rooted my device as shown in this link:
When checked for status, it shows rooted. But root actually is not working.
I knew this as MobileUncle Tools doesn't work.
When boot into recovery mode, it shows root possibly lost, want to fix? I always select yes.
But no luck. Please help me with this issue.
