iMac 21'5" late 2009, nvidia, El capitan 10.11

I was trying this tutorial
To install Catalina in my unsupported Mac. I read other people with my same model (and from What the tutorial says) had succed so I decided to give it a try.
I converted my HD to AFPS and unmount, as the tutorial suggets. Now I cant boot on my Mac. I dont mind loose data but If I try cmd+S and write "fsck -fy" the device its OK but if I write "mount -uw /" says "disk1s1 device is write locked"
