Roll back the BIOS for HP 250 G6 notebook (from f42 to f33)

[M-M-R-2000]

Hi,

Recently, I bought an HP 250 G6 notebook. I updated BIOS from f33 to f42. After updating BIOS, the hard disk makes grinding sounds. I tried to roll back BIOS but I could not.

I checked two methods for the rolling back of the BIOS but none of them not succeed.

Method 1: I created a USB key from the previous versions of BIOS and used "Win key+B" but only Caps lock blinking and have not run anything.

Method 2: I used the "hardware diagnostics UEFI" with the press F2 key. I used a USB key that I created from the previous version of BIOS but I faced with the following error. "Unable to open BIOS Signature file".

I think HP must be very careful about releasing new BIOS.

I will welcome any help from you about my problem.

Best regards,

absolutely correct .. f42 bios version have problem. my motherboard burned because of this problem. Hp has to let bios get back to the old version.
