In a gist. from within x64 folder. file old.mem is backup of firmware that comes on W520. File F402103.mem is the new firmware. cfg.ini is already modified.
What you do is this
w200fw36 /srom ?
This will give you Bus, Device, Function, which you will use in the next command.
Then you do this
w200fw36 /srom 0 /address ??-??-?? /write F402103.mem cfg.ini
Where address you stick from the command above.
You can also do this prior to doing all that above
w200fw36 /srom 0 /dump back_up_file_name.mem
To backup your old firmware... If you want.
But anyway.. After you done you reboot and you reinstall the driver from the message above.
This solves situation where moving USB cable disconnects the device -- as if the USB connector is bad, which is not true, it is not bad.. Plus other problems where USB 3 does not work properly in some situations.
