Camera is not working with MIUI 7-UPDATE NO-5.8.20-4.4.2-BETA

My device is Micromax A116. I installed MIUI 7-UPDATE NO-5.8.20-4.4.2-BETA ROM by fa1zali. After installation Camera is not working. (Earlier, when I installed MIUI 5-4.2.1 by fa1zali camera was working fine in my device.). I tried another method. First I installed MIUI 5-4.2.1 by fa1zali and then updated with MIUI 7-UPDATE NO-5.8.20-4.4.2-BETA ROM by fa1zali even in this method camera is not working. Now I installed MIUI 5-4.2.1 by fa1zali again now camera is working. When I connect my device in my computer and enabled USB connection with MIUI 5-4.2.1 by fa1zali my device is shown as A116i in the computer but in "About Phone" in my device, my device model number is A116

Please help me why camera is not working with MIUI 7-UPDATE NO-5.8.20-4.4.2-BETA ROM by fa1zali even though my device is A116
