dear friend, my mediapad x1 (7D-501U) using B011 chinese ROM , rooted. but when i want to using swap file the application say that my kernel doesn't support it. B011 ROM neither support init.d and setting cpu governors. I'm interested to try KANGVIP ROM. should i unroot my device before flashing KANGVIP ROM? is KANGVIP ROM stable yet?

regards,
adrian
