Once you've done all of these, you can now proceed to the installation process: Connect your phone to your computer via the USB Cable.

Boot into recovery mode. You can do this by holding the Menu button while you power on the device. If it boots into normal mode, try again. Once in recovery mode, select "Install zip from SD Card," then "Choose Zip from SD Card". Choose the ICS Myth ROM ZIP file to start flashing the ROM to your phone.
