Godox XPro-N Firmware Update = Actual Hell (WinUSB vs GuiSTDFUDev driver madness)

I’ve spent hours trying to update the firmware on my Godox XPro-N trigger and it’s been an absolute nightmare.

To do the update, you have to: • Hold MODE while plugging it into USB (puts it into DFU mode) • Use their Godox G3 updater software to flash the firmware • Sounds easy, right? Nope.

Windows keeps installing a Guillemot-signed driver (GuiSTDFUDev) as soon as I plug in the trigger, which makes the Godox firmware tool unable to detect the device.

I tried: • Using Zadig to replace the driver with WinUSB (it works… briefly) • Booting into Test Mode and disabling driver signature enforcement • Blocking the INF file (oem151.inf) via registry policies • Deleting the bad driver using pnputil • Disabling Windows Update driver installs • Reinstalling the Godox firmware tool with admin rights • Screaming into the void

Every time, Windows reinstalls the GuiSTDFUDev driver behind my back — even in test mode, even with blocks in place. I literally watched it switch back to the wrong driver seconds after installing the correct one.

I gave up and I’m contacting local PC repair shops to handle this. I just want my trigger updated. This should be a 2-minute job, not a full-blown battle with the Windows driver store.

If anyone’s cracked this reliably — without just finding a lucky USB port combo — please tell me. Or if Godox is listening: PLEASE update your updater. This process is totally broken on modern Windows.
