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.
This model might be off-market, hence support for this device is no longer available.
You may try some things here https://source.sierrawireless.com/open_at/#sthash.5nzi0sjs.dpbs,
which is similar to WM20452 and running OpenAT.
