    Toshiba P50T-B bios

    I'm asking for your help,
    I have a Toshiba P50T-B laptop which I wanted to update the bios, when I was updating the Bios the computer crashed, and now when I turn it on it stays on black screen.
    I downloaded the manufacturer's Bios updates, made the CD-ROMs with the included software, started them by pressing the letter C as the manual says, but it doesn't work.
    Also try via USB and still can't get me to even read the USB, I don't know what key to start it, I already test with Fn F, Fn B, F, C, B and I don't get anything. I wish you could help me, I thank you very much.

      you have to take down the BIOS Chip and use an external device to read and rewrite with something like an EZP 2010
      Just cook it! It's already broken.

        🛠️ 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:
        đź§© 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

        [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

        ASUS Zenbook Pro Duo UX8402ZA BIOS
        by pirati
        Hello everyone,

        I recently bought a non-working Asus Zenbook Pro Duo OLED UX8402ZA that was listed for parts only. The seller mentioned that it had no display output but that the charging lights worked.

        When the laptop arrived (without a charger and SSD), I connected a charger and confirmed with a multimeter that it was charging the battery. However, when I tried to power it on, only the backlight of the secondary display came on. There was no image, and it didn’t boot into the BIOS.

        I decided to try flashing a new BIOS, but since I didn’t want to desolder...

        HP Elite Dragonfly Bios Crashed - HELP NEEDED
        by techlab
        Hi Guys,

        Looking for some help with an HP Elite Dragonfly.

        The customer explained it was updating the BIOS, the flashing completed, but afterwards the laptop wouldn’t power back on.
        • The laptop has no power but does take the correct voltage.
        • It shows 5 flashes white/amber, which indicates a BIOS issue.
        • I backed up the original BIOS to extract the feature byte etc.
        • I then flashed the BIOS with a clean version from HP’s website, but the laptop still gives 5 white/amber flashes.

        Just wanted to pick your brains on this — has anyone come across this before or...
