Hummmm. I'm looking into this but can't this week I'm super busy. I don't have the 8.9" I have the 7" so it is hard for me to test. I'm not sure if moving the rootme.sh was a good idea. I think the exploit code isn't finding it. You may need a rebuild of the exploit file. I say throw your question in here to see if someone can help. Still, just hope for the best.
