How to make your own CWM flashable stock ROM from "SP Flash Tool" Flashable Stock ROM ? I can't restore my stock ROM of device XOLO A500S IPS by using SP Flash Tool. I need a stock ROM that can be simply flashed by CWM recovery. There is no such ROM available on the internet, as I have searched for it, but couldn't find it. 
Can I make one myself ?
How to do this ?
There are stock firmware images available for download here that can be flashed with the SP Flash Tool.

In terms of creating your own ROM (CWM-based or otherwise), that is beyond the scope of this site.
