Hi Meryl
You are always root in the emulator. That link is about how to gain
root access on a real G1 device.
I think the problem is you are trying to (re)mount a wrong partition.
On my emulator /dev/block/mtdblock0 is mounted on /system, and
remounting it with rw works fine. To make sure what partition you need
to remount use the mount command and see what is mounted on /system.


Regards.
