Extreme II SSD Firmware version 1411 for Mac download and installation instructions

Has anyone been able to apply this update? All I’m getting is an update failed message. After that, it asks if I’d like ot try another drive - if I click yes, it says ‘there is no ssdson this system that match teh model string of this update’.

Which is corerct, as the serail number of my drive is different to the serial first shown.

Running Yosemite, 64bit 240gb file.
