    HP EliteOne 800 G6 BIOS Problem

    Hello, I have an HP EliteOne 800 G6 that I believe has some issues with the BIOS. The computer has entered a boot loop, and the only things it shows are the HP logo followed by an HP BIOS update message, and then everything starts over. I cannot enter the BIOS since, as I mentioned, only these two screens keep repeating.
    I managed to dump the BIOS file, so if someone could look at what the issue is or if you have a different BIOS file that I could test.
    Thank you for your help!

    Please , Use hardware device to backup bios, don't use any software to do it.

      Thank you for your response.
      I have been using Revelprog IS for the past couple of years and have never had any problems with it.
      Does that mean my BIOS backup is not good? I even took the chip off the motherboard and read it directly in the programmer. It passed verification.
      I'm not sure I fully understand what I need to do. Should I try using the CH341A programmer to make a backup?

        Need Clean BIOS/EC Bin File for Lenovo ThinkPad Yoga 11e - Stuck with 0275 Error CMS

        Hello everyone,

        I am attempting a repair on a Lenovo ThinkPad Yoga 11e that is currently stuck at boot with the error: "0275 error CMS" even after setup new bios battery and will not allow me to enter the BIOS/Setup.

        This is a critical issue that I believe requires flashing the BIOS chip directly using a programmer (e.g., CH341A/RT809H), as standard software updates or resets are not possible.

        I have opened the laptop and identified the main BIOS chip...

        NT955XED (Samsung Galaxy Book2 Pro - 15.6) BIOS dump file Request
        by Citymin
        Hi all,

        My Samsung Galaxy Book 2 Pro 15.6-inch laptop has no display and won't boot.
        The charging red LED lights up, but the charging screen doesn't show any indication.
        When I press the power button, the blue LED cycles on and off three times, then the screen doesn't turn on, and the device won't boot.
        (I've tried removing the battery and resetting the device, but the issue persists.)

        NoteBook Model name : Samsung NT955XED-KK51G(Galaxy book2 pro, i5-1240p, 15.6inch AMOLED)

        Looking for BIOS flash file for HUAWEI MateBook X Pro 2019 (MACH-WX9)
        by maanee11
        Hello Everyone,

        I have HUAWEI MateBook X Pro 2019 (MACH-WX9) whose BIOS got corrupted i beleive. I have acquired Ch341A SPI flasher to program the BIOS externally. I see that to program the BIOS, i need BIOS bin/hex file which i could use to reflash it externally via the flasher tool.

        It seems like the support page of this model no longer exist: https://consumer.huawei.com/be/lapto...ro-2019/specs/

        In the website, you can only see specs etc.

        I have not tried to extract the BIOS dump yet as I want to see if there is any ray of sunshine...

        Notice to users of XGecu TL866II Plus / T48 / T56 / T76 programmers regarding BIOS backup file size
        by m1ch43lzm
        Hi everyone
        I noticed on the Xgpro software the BIOS backup files have extra bytes at the end when reading some chips, this is because the Xgpro software also reads the OTP region of those flash chips, and by default will append that region to the saved file
        Programmer models: XGecu TL866II Plus / T48 / T56 / T76

        Example: GD25LQ128D (1.8V), IC size is listed as 0x1000000 Bytes (16777216 bytes) + 0xC00 bytes, those extra 0xC00 bytes will be appended to the end of the saved file by default, resulting in a file size of 16780288 bytes
        There's also an extra OTP Secu.R...

        Lenovo ThinkStation P520 BIOS file needed
        by Forest79
        Hello,

        I got a Lenovo ThinkStation P520 (Type 30BF) from a friend, asking me for a repair. Windows 11 offered a firmware upgrade as an optional update, and it failed.
        The emergency flash procedure from the hardware manual has also failed. So, I asked an acquaintance with better skills to flash the BIOS directly.

        However, the chip (a Macronix MX25L25673GMI-08G) has a size of 32 MB, and the BIOS file from the Lenovo website (extracted with UEFITool) has a little more than 16 MB. Thus, the software my acquaintance used (SiberiaProg v1.45, with a CH341A Programmer)...
