To get the latest software you need to get in touch with the second level software.
Some firmware aren't on the website for many reasons.
Hello. I just bought a Phaser 3040 and wanted to flash it with the latest firmware, which is officially SG1_XC_2.02. But the flashing utility detected the current fw in my unit as SG1_XC_2.04. So you might want to update your site, or if there's a reason why v2.04 isn't offered for DL, I'd like to know it. Thanks.
