[Q] Root and Complete Unroot of ASUS ME175CG topic

I have an ASUS K00Z (ME175CG) fonepad 7.
I rooted the device using flashboot using PC. Then removed all bloatwares. Further I unrooted the device from Superuser.
Now I wish to unroot the device completely and want the Factory Settings with initial firmware including all the bloatwares etc.
Kindly help me to accomplish the task.!!!
Thanks in advance.
