HP 250 G6 F37: Roll Back BIOS
#1
Hi,

Recently, I bought an HP 250 G6 notebook. I updated BIOS from f37 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".

Please send me bios signature file give me

Model PC : HP 250 G6Notebook PC

Bios Revision : F.37 Rev.A
