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.

Hey everyone,

I recently bought a Dell G15 5515 with an AMD Ryzen 7 5800H and 3060 RTX. The BIOS chip on it was dead, and my hardware guy replaced the chip. After that, everything was working fine.

The BIOS is currently at version 1.22.1, and I wanted to update it. I downloaded the latest BIOS version from Dell Support using my ST: FQZMYJ3, but when I tried to run it, it says "unsupported system." I asked my tech guy what he did, and he said he took the chip from another board and flashed it onto mine.

When I check the BIOS using the F12 menu Flash...

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

Hi ya folks,

I have a HP Star Wars Special Edition laptop for fixing.
System pulls the right voltage and fan spins but nothing on the screen
Im leaning towards BIOS.

Ive checked the BadCaps and found that HP 15-an***** are all 16MB files. But my lap has 8MB file.
