How To Remove Ghosts using hub tools or a UZB Stick

Does the [Guide] Firmware Update using PC Controller (Z-Wave Devices) method still work? I've used it successfully in the past to remove ghost devices with a UZB stick (GoodWay Z-Wave Plus USB Z-Dongle Z-Wave Radio Stick WD6050). However, I've tried it multiple times over the past few weeks with no success. Pairing never completes with my C-8 (2.3.9.201). I've tried re-installing everything on a different PC. I've excluded the UZB dongle many times. I've probably tried 100 times overall. The UZB is 10 ft away from the Hubitat, clear line of site. Before I waste more time, can someone confirm that this method still works and that a Hubitat update didn't break something? Thanks.
