Important information for users of Clockwork recovery: right now only version 188.8.131.52 or earlier is supported for installing Sapphire. In some instances even this doesn't work, in these cases you will need to flash SP recovery to install. Please make sure your zip files have a .zip extension, and not .zip.zip. Recommended install order of operations: Install base package + gapps (if using SP recovery, you can mount usb storage in between installs to rename files to update.zip) Boot Sapphire, enter google account information, and let apps sync + install. Don't open market until sync is complete. Once done, install alternate themes and kernels as you wish. It's good to make a backup before trying these.
