That may be, but it doesn't help me get back.
As I mentioned to Barb, I believe that the .bin files in the C:\Windows\Firmware directory are Surface Pro 4 files and not the .bin files that should reside there. I can't unpack the .cab files for the Surface Pro 2, so I'm really not sure. There's obviously
something terminating the installation of the SurfaceProUEFI.inf file. There is most likely a Registry key someplace that's the culprit. I never get any fault message though, just a message that the process was completed successfully.
The Registry HKEY_LOCAL_HARDWARE DESCRIPTION /SYSTEM /SYSTEMBIOSVERSION Type is listed as REG_MULTI_SZ and the Date is MSFT - 0 108.1926.769 MSFT - 10000
While poking around in the Registry, I noticed a file called "Panther" in the Windows directory. The files in that directory appear to be associated with rollback.
