Root Mount-o: permission denied

[B2L]

I just unlocked and rooted my nexus s. Now im trying to stop the phone from reinstalling the custom recovery image and all im getting is problems.

I put in the command

mount-o rw,remount/dev/block/mtdblock3 /system

And every single time i get

mount-o : permission denied

Anyone have any ideas? im worried about rebooting my phone now cause i don't want to go through the whole process again. After reading around on XDA it doesn't seem like you are required to do this. Does anyone know if it will reinstall the custom recovery image if i don't do this step?

If anyone has any ideas i really need help ASAP.

I had the same problem. Check out How To: Root the Samsung Nexus S (Updated 01.20.11) | TheUnlockr

Watch the video instead of the instructions. He is using an alternate method that worked for me.

I found out I was typing it wrong. I just changed the name of the image with root explorer. And that made it much easier.

Btw that video was actually the best guide for rooting the Nexus S that I found. It was definitely much easier to follow than anything on XDA.

I've successfully intalled clockworkmod, rooted and flashed Cyanogen 7 - I don't seem to have the file "install-recovery" where the video says it should be so I can't rename it. Also I've now rebooted many times and have never lost the custom recovery image. This is great but I'm wondering why this has happened?
