    Bios Request for HP DV7-7121NR

    I'd appreciate anyone who can help me with Bios for my laptop.

    The laptop turns on but caps lock stays blinking white.

    I have done some attempts on flashing and configuring but there are incomplete things that I cannot get through (it´s been lots of days of reading and downloading many files, watching videos, making mistakes on purpose and others not so much)

    The faulty Bios backup I got has the exact information for the new "clean" BIOS. Maybe you can help me ¨see¨ where the problem was with the old Bios.

    I manage to do the following:
    1º Decompress the Bios from HP exe from drivers backup website
    2º Decrypt the bin file
    3º Split the EC and System Bios
    4º Backup the corrupted/damaged BIOS
    5º Flash the new Bios to the laptop
    6º Remove the ¨Manufacture programming mode is in unlock mode¨ warning using the HP BiosConfigUtility64 through the config.txt file
    7º Use the DMI tools on a FreeDOS usb stick to manually write: Product Name, Product Serial Number, Product Number and System Board CT Number

    8º STUCK: On boot still shows message for 2 missing data fields. Can´t write the Product Configuration and Product Family since none of the DMI exes show them so I can´t edit them.
    The config.txt file doesn´t show any of these info, the ones I´m stuck or the one I successfully typed in, only the Unlock/lock mode
    I used the Wistron DMI exes that let me write the invalid ones, but doesn´t show the 2 missing data fields.
    The Quanta 193 shows me other data but it always shows wrong symbols on already correct data (eg Product Name shows ¨random¨ characters)

    I´d appreciate if anyone can complete the information:

    Serial
    2CE2231G09

    System board CT
    RCPATAR11-0220

    Product name
    HP Pavilion dv7 Notebook PC

    SKU
    B5R49UA#ABA

    PCID
    078f190000205720000620100

    Board
    Kroyer/Yeats 1.0MB
    11277-2
    48.4sv01.021

    I attach the 2 Bios, old one and New one ¨clean¨

      The Bios you uploaded is identical to the one I posted as Clean, HP dropped support for this laptop so no files can be acquired from HP website.

      So the Bios still doesn´t have the Product info that I mentioned on my post #1. I cannot write the mentioned (Product Family and Product Configuration) missing data fields through any of the DMI tools or the HP BiosConfigUtility64.exe

            🛠️ MSI GP75 Leopard MS-17E71 – No Display, Deep BIOS/EC Troubleshooting
            by macabook
            Hello everyone,

            I’m currently working on a dead MSI GP75 Leopard (MS-17E71) motherboard (i7 CPU, NVIDIA GPU) with a no display/no backlight issue initially. After extensive investigation, I’m at a critical stage involving EC firmware, BIOS/ME region interaction, and possible deep corruption. I'm seeking advanced insight from anyone with experience in EC/BIOS sync issues or PCH-level behavior. Here’s a full breakdown:
            🧩 Initial Issue
            • Board powers on (fans spin, keyboard lights up and can be adjusted, caps lock led lights), but no display or backlight
            • External display (HDMI) shows
            ...

            ASUS TP500LA BIOS request/repair/merge?
            by jbonavita
            Hi, my laptop wont boot at all
            With original bios no POST, only LED lights
            With alternative BIOS from model TP500LN (flashed via programmer) the notebook works again
            Some issues
            A- with bios from 500LN, it won't update from bios of model 500LA (from 500LN v203 to 500LA v300)
            B- If updated from 500LN version 203 to 300, the battery stops being recognized

            Things I tried

            1- Update / clear ME: Took the non working bios, made a backup, and did this: https://www.badcaps.net/forum/troubl...theory/trouble...

            [REQUEST] Dell G3 3579 BIOS Password & AMI Protected Range/BIOS Guard Unlock
            by zenius
            Hello, I have an old Dell G3 3579 (ST: 2WQ7LP2-8FC8) with a newer 8FC8 BIOS password. I have successfully attached to the flash chip (W25Q128JVSQ) on the motherboard with a CH341A programmer and made several modifications using Intel FIT (e.g., allow software SPI write) without bricking. I was also able to boot to a modified GRUB shell where I attempted to edit many BIOS security related options like BIOS Guard/Lock, Flash Signature Override, ME FW Image Re-Flash, etc.

            Unfortunately, some of these modifications like to Intel BIOS Guard failed because it is fused into the PCH. Also,...

            HP Pavilion Gaming Laptop 15-ec2523nd - Dimm2 slot disabled after corrupt bios repair? Advice requested.
            by Bloodhoundje
            Hi everyone,

            I have been doing hardware repair as a hobby for some years now and recently decided to learn about repairing laptops as a fun challenge.

            I managed to get my hands on a "HP Pavilion Gaming 15-ec2523nd" notebook that only shows a white power LED and doesnt respond to anything.

            After initial testing I concluded the bios seems to be corrupted since all voltages are normal and there are no shorts. HP has a feature for a bios restore from USB with winkey+B for this model. This did not work.

            I have desoldered the bios chip (GigaDevice...
