    HP Omen 15-ax004np BIOS

    Hello,
    I have an HP Omen Laptop 15" 15-ax004np (SN:5CD6242KJH).
    Updated the BIOS from 2016 (F07) to the latest from 2020 (F56 revA) with HP application on Windows 10 (sp111733.exe).
    All went well at first, programming and verifying. However the laptop didn't boot...
    Got it open, removed battery, but still the same.
    It has a Winbond W25Q64FV flash I managed to read it with Xgpro and a TL866ii.
    The motherboard is a DAG35AMB8E0 REV:E.
    I didn't find this laptop model in the forum, but there lots of threads about the mainboard.
    If you guys can help me out with the bios file, it would be great.
    Thank you!

      Thank you for the file!
      I tried to flash the bios with it several times, but keeps failing the verify.
      Checked the WP line and was ok.

      Anyway, I boot up the laptop and it worked!
      However, Product information is missing.
      It boots to windows.

      I'll have to buy another W25Q64 and program it with the file you sent.
      Thank you again.

        You'll need to transfer DMI data from your bios backup to the Gayyum's bios with a hex editor using offsets mentioned in his post.
        Do the same with the Windows key - offsets: 278000 -27803F

          Thank you Vesko356 for the help!
          I'm searching the forum on how to transfer the DMI (data and key).
          The new chip will arrive this week and also a different programmer.
          I'll reply again as soon as I have news.
          Thank you again.

            Hello there,
            I finally got it working.🎆
            Changed the DMI and key data with an hex editor.
            Programmed 1 and then a second flash, but for some reason it wouldn't start.
            It was always showing 5 longs and 3 short pulses on caps lock led.
            I decided to program another flash out of the laptop, instead of in circuit, and it worked...
            Thank you qayyum786 and Vesko356!
