finally managed to root micromax a80 , using fly iq275 firmware.everything works perfect, except the touch keys combination. as fly iq 275 have home key in place of menu key in mmx a80.
it is possible to port rom made for micromax a75. to micromax a80
i used recovery.img of micromax a75. and for porting in flashable zip
just replace boot.img. from iq275 firmware.
