Windows 10: Error updating HP WMR Headset Firmware

I'm trying to set up my HP Mixed Reality Headset on a new computer and I'm getting an error.

My Mixed Reality portal hangs forever on the 'updating your headset firmware' step. In the device manager, the headset shows up with the name 'HoloLens Sensors' and the properties has the message 'Device Error : 0x80040201 : E_DEVICE_FIRMWARE_UPDATED'. I have tried uninstalling and reinstalling the device, the driver, and the Mixed Reality portal.

:)

 

WMR no longer working after last update (October 2019)

After the last windows update KB4524147 which included an update for the WMR drivers. I am getting a 14-2 error code and the WMR portal does not recognise my HP WMR headset. I can redo my boundry etc but the headset shows no display.

I updated the GEFORCE display driver to the newest version...

 

Lenovo Explorer WMR - Error Code 2181038087-5

I've been struggling to get my brand-new Lenovo Explorer to work. I have 2 VR capable computers, both well within specs for WMR, both throw error code 2181038087-5 despite my exhaustive efforts.

Here are the specs,

Main PC:

• CPU: Intel i7 4790K
• Ram: 32GB DDR3
• MB Chipset: Intel Z97
• GPU: GTX 1060 6GB
• Windows 10 Home, Version 1803, Build 17134.112
  
• Screenshot of Device Manager and WMR error code: Imgur

Streaming PC:

• CPU: Ryzen 5 1600
• Ram: 16GB DDR4
• MB Chipset: AMD B350
• GPU: RX480 8GB
• Windows 10 Home, Version 1803, Build 17134.112
• Screenshot of Device Manager and WMR error code: Imgur

So far, I have attempted, on both machines:

• Unplugging all other devices and hubs on USB 3.0 and 3.1 ports
• Unplugging and plugging back in the HMD into a different port
• Confirming Host controllers have Microsoft drivers (see pictures)
• Updating UEFI to latest firmware
• Disabling USB selective suspend settings
• Disabling Legacy USB Support in UEFI
• Uninstalling all USB controllers and devices in the Device Manager, and allowing them to reinstall on a restart
• Installing beta versions of the "HoloLens Sensors" firmware
• Plugging HMD into a powered hub

Suggestions?

 

Recent WMR updates have completely broken WMR for me

Ever since the latest WMR updates, WMR hasn't worked correctly at all for me:

• Edge won't play WebVR videos. After the update this worked intermittently (Edge would play a video, but crash). After the most recent Edge update it's been completely broken. Usually the videos are black and when I click the googles to go into immersive
  mode nothing happens. At best, many sites tell me to get a WebVR compatible browser. Note I've tried this with and without the 360 viewer plugin. Doesn't seem to make a difference.
• I have a laptop with an external graphics card. I used to be able to plug my headset into the laptop's HDMI port. Now this is broken. The headset won't start up unless it's plugged into the external graphics card, which is extremely inconvenient and doesn't
  seem to work correctly with SteamVR (Steam VR will keep telling me my headset needs to be plugged into my primary display).
• For some reason every time I start Edge now, Steam VR starts up and then crashes. Then Edge crashes. And this cycle repeats.

So my headset's basically a worthless brick right now and has been for a couple of months. I can get into the cliff house but that's about it. I keep hoping the next windows update will fix this but no luck so far. I'm not sure what to do.
Everything worked flawlessly before that WMR update.
