The USB downloader method is much more powerful (and preferrable, of course), but at this time we simply don't know how to make the PW hardware enter that mode. If anybody figures out a hardware "key combination" that makes the PW show up as 15A2:0052 (or even as another unsupported device), that'll be a major breakthrough for PW debricking.
USB Downloader mode sure simplified things when the kindle was "too bricked" for runme.sh script debricking which required opening the kindle and using its internal serial port. In fact, simple debricking is so simple that it is now used to do a "full factory reset" without needing to uninstall a pile of hacks. Yes, we need that for the PW too.
I sure hope we do not need to remove the cover of a PW to activate USB Downloader mode.
