Removing ads on 5.1.1

I have found a way to remove ads on 5.1.1, it is exactly the same way as 5.0.1 except you NEED root for it to work.
Type in the following commands in a command prompt. Be sure USB debugging is on and it is securely connected to your computer. Although you do type reboot as the last command, the tablet turns off, just press the power button . This was successful on two of my tablets. :D

Code:

---

adb shell
su

---

At this point grant superuser access from the tablet

Code:

---

pm hide com.amazon.kindle.kso
exit
reboot

---

In theory this should work from a terminal emulator straight on your tablet but I have not tried it out
