Okay, well make sure you have metamorph installed from the market of course. Next unzip the files you downloaded in this thread that you want to install and put the folders into the AndroidThemes folder on your phones SD card. Next open metamorph and start checks (sometimes metamorph randomly closes, just reopen it). Go to Pick existing theme, click on the folder of the theme you want to install, click the name of that folder again, then click on the yournamehere.xml file. After that opens up just click apply all. Before you do all that I would also make sure to go to mm settings and check Disable all warnings. Hope that helps!
