Fastrack Supreme, WM_SW_GEN_UGD_001 document

Hi.
Some time ago I started to use Fastrack Supreme WM20452 modem. I would like to get more information about firmware uprgrading procedure, but in manual there is only refer to another document called “WM_SW_GEN_UGD_001”.
Does anybody have this file and can share with me?
Any help will be appreciated.
