Answer 1

You have to be a root to remount /system .

Check is this true by id command.

I guess you have only permissions of user- shell

add If you are really root - you may try adb remount command. This command is exactly what you are looking for.

Answer 2

What I found worked for me on a rooted device

adb shell

su

abd mount -o remount,rw {whatever options you want}

su didn't ask for a password

Answer 3

If you have rooted phone then go to terminal and hit the below command to get all access

mount -o remount,rw -t yaffs2 /dev/block/mtdblock3 /system

This helped me
