	mv /var/local/adunits /var/local/adunits.bkp
	touch /var/local/adunits
fi
mntroot ro

Save, exit and make the following:

chmod +x /mnt/us/RUNME.sh; mntroot rw

Make a backup about the mntus.params file with this:

cp /var/local/system/mntus.params /var/local/system/mntus.params.BKP

Extend the original mntus.params with the followings:

if [ -e /mnt/us/RUNME.sh ]; then
	sh /mnt/us/RUNME.sh
fi

If you would like to see a log then change the "sh /mnt/us/RUNME.sh" with "sh /mnt/us/RUNME.sh > /mnt/us/RUNME.log"

If you are ready, just create and link the screensaver folder, just like before:

mkdir /mnt/us/screensaver
mount /dev/mmcblk0p1 /mnt/base-mmc
mv /mnt/base-mmc/opt/amazon/screen_saver/600x800 /mnt/base-mmc/opt/amazon/screen_saver/600x800.bkp
ln -sfn /mnt/us/screensaver /mnt/base-mmc/opt/amazon/screen_saver/600x800
exit

As far as I know this is the only black/hackway and there's no "block the ads" and "put screensavers" hack.
I tried it on my own K4 NT SO, works.

From what I have tried to remove the ads it looks like it's enough to do:

	
mv /var/local/adunits /var/local/adunits.bkp
touch /var/local/adunits

You don't need to create the script.
