Erase Cyaniogen Recovery?

I have a rooted Xperia M c1904, which had a cwm recovery, after installing Cyanogen 12.1, it got replaced by cyanogen recovery, I tried flashing other recoveries through flashify and rashr, didnt work. I cant flash anything at all. I heard some people talk about twrp and then 'dd'. Could someone come up with a solution? Thankyou in advance.
