STOP trying to INSTALL the themehax installer again.
You DO NOT need to install anything anymore.
All you need to do is rename your ropbin file that you downloaded and upload that into the root of your SD card.
Now what you rename it into, check the original post. If they doesn't work, then I don't know.
thank you it works now, althoug i have to do that thing while on shutdown screen because i always get stuck at a yellow screen if i do it on boot.
