Hi mate,
We have to try with an older one v.F.35
Then to reflash that Bios Mod You need to Downgrade !
So Downgrade to version F.35 use the Recovery Method

Get this HP tool to prepare an USB Stick and rename It as
HP_TOOLS :
http://ftp.hp.com/pub/softpaq/sp52001-52500/sp52264.exe
And copy into the Recovery Files :

Then follow the Procedure . . .
With the flash drive plugged in, hold down the Windows key and the b key.
Press the power button while continuing to hold down those two keys.
After a few seconds, the activity light on your flash drive will flash.
You can now stop holding down those two keys.
The screen may stay black for as long as 40 seconds and you might hear some beeping,
but eventually a screen like this will come up.
Wait for it to flash your BIOS and verify the new contents. Then it'll restart and your computer shouldn't be bricked anymore.
Here You go Bios Mod F.35 :
