First go to shell using

adb shell

Then remount the system folder as writable using following commands

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

Then change the permission of system folder to Read, Write and Execute using

# chmod 777 /system/app

Try adb remount in terminal. If you want to do it from the device shell, see this question on how to remount the file system with write permission.

Just type in your android device terminal 

       su

and then

       chmod 777 system/app

su- grants you superuser permission

and chmod 777 file, change the permissions of the file to read, write, and execute..
