It's not that hard to find your way around it. Just install it, reboot your computer and you're good to go.No, but I could get away with some explanations
Run an instance of SWDownloader and try burning any firmware to any M028T device as this will put the device in download mode which is what we need.
After that, open BusHound and go to the device's section. Tick on the Marvell WTP device together with the "auto select hot plugged devices" checkbox as shown in the images I've provided.
That's it. You'll be ready to start capturing.
Now just plug any flashable modem and make sure you tick the 'Erase All Flash' option.
That's what I want captured.
