Next, I needed to make /system writable on the Tablet Z.
The instructions below worked for me:
I used almost the same commands except busybox was not available on my tablet.
Instead, I used ps and kill command to remove the /sbin/ric process.
shell@android:/sdcard/hydrive $ ps | grep ric
root 308 1 1316 616 ffffffff 00000000 S /sbin/ric

NOTE: This is a temporal solution, meaning you will need to do it again after your system reboots.
