    Use the Guides to find and extract a virgin bios

    [Guide] How to find the right HP bios version to flash https://www.badcaps.net/forum/troubl...flash?t=122195
    [Guide] How to extract ready for programming dump from HP update executable file https://www.badcaps.net/forum/showthread.php?t=121948

    Copy the DMI (serial,feature Byte,win key) from your backup to the virgin bios using a hex editor.Select the same offsets (select block in HxD) in both bios,copy from the old,paste to the new.

    Offsets: 0 - 10FF and 8000 - 803F

    HxD Hex editor https://mh-nexus.de/en/hxd/​

    Sometimes the 5long blinks, 3 fast blinks is caused by loose ram slot pins, cracked solder balls under the SOC.
