Well the rooting wasn't the problem at all (Phone is rooted). I used mobileuncle mtk tools to flash a new recovery but it didn't work. i tried to install cwm, twrp and even ctr but all of them didn't work for my device. the device is mtk6572 (ubifs). on booting i hold the keys required to goto recovery but it only displays a white screen and then boots normally without displaying any recovery!
