Its very simple. First you have to download rubix 1.6 zip and save it to root of SD card. Next, go ahead and download blackjuice 1.6 theme and do the same thing. Make sure you make a backup of what you are running now either in rom manager or in bootstrap. After you backup, wipe data and cache. After you wipe, install zip from SD card. Choose Rubix1.6.zip. after that is downloaded, you have to install zip from SD card once again. Choose blackjuice1.6(blue or green whichever you download) and install. Once complete, reboot and you should be good to go.
