Unhappy [Q] LWW not booting, no recovery after /system format

I think I've bricked my phone.

I flashed Carbon Kitkat ROM on LWW with CWM. I later flashed MIUI 4.7.27, but eventually formatted /system. No there is no recovery. MIUI was pretty slow to keep continuing with the ROM so I wanted to flash Carbon back, hence flashed boot.img.
As currently there is no recovery, device just loads a blank screen.

Please help guys to install recovery and any ROM to get the phone work.
