I have been unable to update my Envy X2 BIOS using sp69946.exe. The executable does brings up a InsydeFlash 4.37 window with blank fields for ID and versions of the current and new BIOS. After several seconds, a popup appears warning me that "No WMI! Do you want to continue?"
If I answer OK, the current and new BIOS version fields show 12 and 14 respectively for less than a second, followed by a reboot. Using Windows System Information, I see both before and after the attempted BIOS update that Windows detects my BIOS as InSyde F.12, 5/8/2013.
I am running Windows 8.1 and have disabled my firewall and anti-virus based on a previous thread, but the results are always the same.
Try restoring the BIOS settings to default before applying the update. Once you're in the BIOS you should be able to press F9 to restore the default settings. Try applying the update after that.
If that doesn't work try recovering the BIOS before applying the update again. TO recover the BIOS you need to press the Windows Key + B on boot. You can see a more detailed guide here: HP Notebook PCs - Restoring the BIOS.
Hopefully that works.

I stumbled on to the answer when the tablet detected an error during shutdown and presented me with a series of menus that led to an option to upgrade the BIOS. I clicked on that control and the update process launched a series that popups showing the steps of reflashing to V1.14. Inadvertent on my part, but the tablet's code is now where I want it to be. Thanks for your time.
