NW_WM_FW.UPG
to root directory on device (the one with MUSIC directory) - use scsitool
scsitool list_devices

/dev/sg4
scsitool -d -s nw-a50 /dev/sg4 do_fw_upgrade
(may require root)
- device reboots, upgrades a little, reboots again and upgrades again (fully)
If your player has adb on, there is no need for scsitool.
Turn USB Mass storage OFF.
Copy NW_WM_FW.UPG

adb push NW_WM_FW.UPG /contents/

See Linux section. You'll have to build scsitool
yourself, good luck!
