mobile

I have xperia M which i think is bricked now. It gets stuck ay the sony logo and later a black screen appears with a white horizontal bar at the bottom of the screen and restarts all over again. it is rooted but the bootloader is still locked. while connected to pc it shows qhsusb_dload and detects only fastboot mode in flash tool. it still runs the stock jelly bean which i updated using pc companion. Earlier i installed xposed framework and went goofing around in build props, may be thats what caused it. Please someone help me fix this.
