Whenever I try and mount system as writable I get

Mount: operation not permitted

The error occurs whether I use adb or terminal.



Sorry! Realized after posting I'd gone into the wrong forum! Could a mod move it please? Or delete it and I'll make a new one?

Maybe try to download the ICS rooting.zip and run the macro using fastboot.

Open up terminal emulator and type:
su
mount -o remount,rw / system

This won't work on the a100. You still need the mempodroid exploit.

Works on mine. It's only a small price to pay to have the CM9 goodness on my tablet and it's R/W until next reboot.

This method doesn't work on my tablet.
Isn' there any other method to acquire r/w?

Either of the ICS root methods in the dev section should fix it

You might try "busybox" after the su and before the mount command, e.g.: 'busybox mount -o remount,rw /system'
Busybox knows about these things.

just type in "su" enter it then type commands as normal.
your permissions wont let you at present,
letting the system know to run su works good.
hope it helps!
