    Casper Nirvana X600 IP3_DN21C_MB_V11 - Main BIOS & EC Dump Request / Extraction Help
    by agestec
    Hello everyone,

    I am working on a Casper Nirvana X600 laptop with the IP3_DN21C_MB_V11 (20230629A) motherboard.

    The board uses an ITE IT5570E (128KB) embedded controller. I need to extract or obtain a verified EC firmware / working dump for this specific revision.
    • EC Chip: ITE IT5570E (128KB)
    If anyone has a working backup or can guide me on how properly cut/extract the 128KB EC region from the main update package for this specific board layout, I would greatly appreciate it.

    Thanks in advance!...

    🛠️ 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

    Acer Predator Triton 16 PT16-51-99GL (DA0ZQDMB8AE Rev. E) - Looking for original 32MB BIOS dump (Winbond W25Q256JVEN)
    by Trademark
    Hello everyone,

    I’m hoping someone can help me locate a verified original BIOS dump for my Acer laptop.

    This is NOT a BIOS password removal request.

    I’m looking for an original 32MB SPI BIOS dump to use as a reference in case my BIOS firmware is corrupted. My plan is to first dump and back up my own BIOS as soon as my programmer arrives. I am not planning to blindly flash someone else’s BIOS.

    Laptop Information
    • Model: Acer Predator Triton 16 PT16-51-99GL
    • Motherboard: DA0ZQDMB8AE Rev. E
    • Main SPI flash: Winbond W25Q256JVEN (32MB)
    • Secondary

    [Problem/ Request] Bricked TongFang GK7MRFR BIOS
    by cr4zychriss
    Hello everyone,
    I am requesting urgent assistance to unbrick my laptop, a rebranded TongFang GK7MRFR chassis. The laptop is completely dead following a faulty in-OS EC flash attempt.
    I have successfully used a CH341A programmer and can read/write/verify both flash chips, but using my backups/extractions has failed to restore power. The root cause is likely a corrupted Intel Management Engine (ME) region or an incompatible EC/BIOS pairing. System & Hardware Details
    • Barebone / Chassis: TongFang GK7MRFR
    • MB: MB: GK5MP5X V1.0 Prod :GK5MRFV10T04201310281
