Sorry, but this looks like one of many hundreds of almost identical pages where they just change the device and ROM names to create each new page. These instructions almost certainly won’t work - typically aftermarket ROMs for a device only provide updates up to 2 or 3 versions newer than the Android version the device originally shipped with due to hardware requirements.
