ASUS ROG GL703GE EC and BIOS dump needed (DABKNBMB8D0)

[mitchw]

Need both BIOS dump and EC dump for the DABKNBMB8D0 REV. D laptop.

Bit of a history on the board:
Audio codec ALC295 removed as it was getting hot, no improvement.
Already tried it with one unverified BIOS and it didn't work. No reaction on power button press. 3.3V LDO present. No shorts. Sometimes it kinda starts, but only partially (5V and 3.3V and 1.05V present, no other rails/VCOREs). Won't charge the battery either - battery charges fine on other board. No activity on charger IC data lines also.

EC is next suspect, but would also need to find a way to flash it (ITE 8587E). Only have CH341 and TL866II at the moment.

This is EC file but need original bios for build new file bios.

Thanks, will try this. What programmer do you recommend for ECs?

Thank you. I can borrow a RT809H in a day or two. Any info on how to hook it up to the EC?

Looks like the connection is via the keyboard cable slot.

Hey, finally got the RT809F that I ordered few months ago. I also got the PEB-1 expansion board for it.

The RT809F itself works fine, with it I reprogrammed KB9022 on 2 boards so far.
But the PEB-1 with IT8987 on this board it is giving me nothing but frustration.
For 4 straight hours I troubleshooted it with no avail. I first soldered the new IT8987 on the ITE Adapter board that plugs into a PEB-1.
Got the "Chip failed enter into the ISP status, operation terminated." every time I wanted to read it or do anything else with it.

I then resoldered the chip on the board, and the board actually powers on (kinda), CPU and GPU gets hot, but there is no image and no activity on the USB. Also no battery charging. There is possibility that the EC I put on was pulled from some board that already has some code in it. Or there is some other problem and the EC got flashed from the main BIOS and there is nothing wrong with it.

I then discovered that there is a debug port near the EC that accepts the 24-pin flat cable. Again, I connected it, set the lines on the RT809F (triple checked them). Did all the right things (connected the ground wire), plugged the board in, etc.
And I am still getting the darned: "Chip failed enter into the ISP status, operation terminated." in RT809F program.

Any suggestions why it is failing the detection? I am suspecting the PEB-1 board, but can't prove it.
The reason I replaced the EC on the first time is that it was getting slightly warm, but there is a chance it was fine, just flashed with some wrong program.

Thanks

Any luck with the board. I got 5 of those board that I have to work with. Will get the programmer tomorrow. I do have the original BIOS on 2 other functional working motherboards.

Funny enough even though the motherboards are the same model and revision, they have 3 different bios chips! That's nuts. Am I looking at the wrong component?

Here is a board diagram that I found out https://www.badcaps.net/forum/showth...ht=DABKNBMB8D0

The chips that the board has are the following 3:

Board model: DABKNBMB8D0 Rev. D
Windbond W25Q128JVSQ
Gigadevice:25B127DSIG
MACRONIX: Can't find the board, Will look it up later.
