Hey there fellas, great source of help you have here, congrats everyone!
I've tried on different PCs but no matter what, I cant make my XT925 shows up as a COM port and thus, I cant work on it on QPST!
Fast boot it in BP Tools do give me enough permissions to do the job?
5/ Run QPST Configuration from your Windows Start menu. Switch to the second tab ("Ports") and choose "Add new port" (bottom left button). You should see a COM port associated with "USB/QD Diagnostic". Select it, then press Ok. You can close the QPST Configuration window now.
