I have an hp pavilion zv5405us. I went to the downloads page for it and downloaded SP30397.exe (BIOS vF.35). I followed the instructions to a "T". It went through the process, dialogs, and shutdown as if it was successful. But upon verifying the version change, my BIOS version is still F.30.
I even tried installing it again, and it still is at F.30. I contacted hp support and they gave me the run-a-round and wasted my time, shitheads . Anyone have any advice???
