    problem with asus tuf A17 FA707NUR

    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.

          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

                      Hello everyone,

                      I need a full 32 MB BIOS dump for an ASUS TUF A17 FA707NU laptop.
                      Mainboard: DAONJSMBAFP REV F
                      CPU: AMD Ryzen 5 7535HS
                      EC chip: 25Q16
                      Main BIOS chip: GD25B256 (32 MB)

                      The original BIOS dump I have is corrupted – the board powers on (keyboard lights, charging works) but no logo, no display.
                      I already tried the official ASUS BIOS 316 (.CAP) but it only contains the BIOS region, not the full dump with PSP/Descriptor.

                      If anyone has a **working full dump (32 MB)** from a similar board (FA707NU Ryzen 5 7535HS), please share it or DM me.

                      Thank you in advance!

                              You were asked for a picture of the QR code on the motherboard, not the case..write the rest with the keyboard..
                              post the contents of the bios chip even if it is corrupted..
                              The bios chip must be unsoldered from the board before writing or reading..
                              do not use the clip, you may have errors..if you do not have anything to unsolder it with,
                              solder wires between the programmer and the bios chip..
                              you need an SPI programmer...here is a video for example..https://www.youtube.com/watch?v=DWWi...nnel=ThisIsHow
                              read the forum rules..

                                  With ASUS, not everything is quite so simple. I will show you my way. It may be longer or harder but it is the right way to do it in my humble opinion.

                                  For example, you can have 3 similar ASUS motherboards, all being the same model, all of which will have different BIOS versions.

                                  I will give you an example and my version of preparing BIOS from ASUS website and in the process I am always cleaning Intel ME while doing it so you have fully cleaned BIOS, no DMI data, no password, nothing.

                                  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...

                                  ASUS TUF GAMING Z790-PLUS WIFI - BIOS Help
                                  by grimacelord
                                  Hello,

                                  I have spent the last hour on this and I guess this is just over my head, so here I am.

                                  I have an ASUS TUF GAMING Z790-PLUS WIFI motherboard here that needs to have the BIOS updated in order to accept the latest CPUs.

                                  The BIOS chips seem to come as a set of two: GD25B64ESIG and GD25B128ESIG. My guess is one of them is a fail-safe for the main BIOS? I really don't know. Or one of them is ME and other is BIOS? I don't know.

                                  Anyway, I took dumps of both chips and then downloaded the latest update for this motherboard from ASUS's website...

                                  A- with bios from 500LN, it won't update from bios of model 500LA (from 500LN v203 to 500LA v300)
                                  B- If updated from 500LN version 203 to 300, the battery stops being recognized

                                  Hello... Where do I start. I have 2 questions/scenarios that might bring this laptop back to life, so here it goes!

                                  I have this laptop (Asus UX52VS) where I was flashing the BIOS to it and it froze during the process. I didn't have a reliable BIOS chip programmer at the time (It was a CH341A USB Programmer from Amazon where it took hours just to get the clamp on the chip and then every time I read, it gave me different results/corruption, and never would pass the verify test as no 2 reads were the same data), so I brought it to a shop. They had it for almost 2 months, but during...
