You have tried the Recovery Bios ?
Let me know
Regards

It's a Brick, I will upload the Recovery Files quickly !

Use this tool to prepare an USB Stick then rename It as HP_TOOLS :

ftp.hp.com/pub/softpaq/sp52501-53000/sp52509.exe

Then extract the Recovery files from this archive and copy them into USB Stick :

http://rghost.net/7cQqKmFG5

Follow the Recovery Bios Procedure :

Put the USB Stick into the USB port and switch on you laptop pressing WIN + B Keys
wait the led signal to read from USB and then release the Keys !

Let me know

Format an USB flash drive with an FAT partition, and create this folder structure:

USB_Name:\Hewlett-Packard\BIOS\Current

!!!!case sensitive!!!!

Then take Recovery files I sent and rename Rom.bin and Rom.sig as

68CVD.bin
68CVD.sig

Copy them into the "Current" folder of USB flash drive.

In order to initiate the BIOS recovery, "Window Key + B" must be pressed during powering on the system.
BIOS recovery can be manually forced by pressing and holding the 4 arrow keys and pressing the power button.

Let me know
Regards

P.S. I would You get the Tools to continue our work Wink

So it seems this Bios is RSA Internal Checked !
We have to try to Downgrade !

Using this procedure please Downgrade to oldest Bios . . .

F.03 01-2010 6.2 MB sp47212.exe

Then i will upload a Bios Mod for F.03 and if It will work then We will update to
any new Bios version bypassing the RSA Check !
Let me know
Regards

P.S. use Recovery Method to Downgrade so unpack ROM.cab file using WinRar v. 5.20 or
above then rename like I done and try !
