problem with asus tuf A17 FA707NUR

[boticario]

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 any separate EC binary region.
If anyone has a verified clean EC dump (.bin, 128 KB or 256 KB) for this board (FA707NUR / FA707NU, same revision), it would be very helpful.

Board info:

• Model: ASUS TUF Gaming A17 FA707NUR (2023)
• EC: ITE IT5570VG-256/CX (marked as KU1 on the board)
• I can flash via CH341A + SOIC-8 clip or through service pads (TP_ECCLK, TP_ECDAT, TP_RST, etc.).

Additionally, in the boardview I located a J1 jumper that connects GND and +3V_RTC.
If anyone knows whether this or any other pad combination can safely force an EC reset / RTC clear (without reprogramming), I’d appreciate the info — just trying to confirm if ASUS designed a manual reset path for the EC flags.

Thanks in advance — any EC dump, partial read, or reset tip would be great to help restore this unit.

post the original contents of the bios chip(main)..post the EC bios if possible...

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.

So, the EC firmware I have is the stock one contained in ASUS’s official BIOS package, not a dump from an external programmer.

If you need, I can share the exact BIOS version (.CAP) and specify which EC version it installs.

Thanks again for your help — I’m trying to confirm whether a full EC reflash could restore proper EC behavior before going that route.

Code 43 on NVIDIA GPU may be faulty VRAM or something else related to the GPU itself, or VBIOS (stored on a separate chip, usually a 25Q80 or 25Q16 1.8V chip near the GPU)
If you want to flash EC assuming you have a programmer for it, the firmware starts at 21000h on the BIOS dump (search for ITE until you see ITE EC or similar string, then select the block starting after FF FF FF...) + the size of the EC chip in KB, for 256KB (262144 bytes), select from 21000h-60FFFh (length 40000h) with hex editor and copy/paste to a new file
Don't know if the IT8390 programmer is suitable for this IT5570 or you need something more expensive like SVOD4 or Vertyanov Successor

You can dump the EC chip contents with programmer and compare it to what's stored in the attached file, at least the header should look similar

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