Thanks i study after i respond but the first thanks very much for your answer...

Hi, thanks for your answer.

The BIOS and EC firmware I’m using are the official ASUS releases, available directly from ASUS support website for the TUF Gaming A17 FA707NUR (2023).

The EC firmware version (for the ITE IT5570VG-256/CX) is R3.00 or R3.01, depending on the BIOS version (300 or 303).
I extracted the .CAP files and separated DXE and EC-related modules using UEFITool and IFRExtractor, but the EC binary region isn’t explicitly separated inside ASUS’s update packages — it’s flashed automatically by their EZFlash utility during the BIOS update....

Hello everyone,

I’m trying to recover an ASUS TUF Gaming A17 FA707NUR (Ryzen + RTX 4050, 2023 model).
The laptop powers on, fans spin, but the dGPU (NVIDIA) is not properly initialized — sometimes it shows up in Device Manager with Code 43, sometimes black screen.
After several BIOS downgrades/upgrades (versions 300, 301, 303) and EC resets, it thinking looks like the EC firmware (IT5570VG-256) might have a persistent fault or flag stored in flash.

I already extracted the BIOS .CAP files and DXE sections with UEFITool and IFRExtractor, but I couldn’t find...

thanks verymuch...
