Assistance with identifying resistor value on 820-02918 A2992 board?

Working on a 2023 M3 A2992 unit with 820-02918 board, and it uses a new USB-C power architecture, with rectangular controllers. I do not have a perfect-matching board, so have been repairing this one the old-fashioned way (slowly).

I managed to blow-away a single resistor that I can't find and can't determine the value of. It connects to ground, so I went ahead and stuffed it with a 100K resistor in case it's a simple pull-up. But, I'm now having issues with that side of the board, and am curious if it's possibly related to this resistor! I have no schematics and no board view, so working blind here.

Photo attached; for reference--this photo was taken of the FAR-LEFT-SIDE of the board when the board is lying CPU-down, and the battery connector oriented towards yourself. It's a small resistor underneath the 2nd-down USB-C controller IC.

THANK YOU IN ADVANCE!

By the way: I am hoping someone has this same board and can measure that resistor for me; I know the schematics don't exist and the resistor isn't marked, of course.

Cannot locate the components with the picture. Can you please take another picture that shows exact location? This is like a close up and need the picture shows the general surrounding components. My buddy from Netherlands also looking for schematic but no luck yet. I will check with the Russians and Indonesians if they have it. I usually buy the schema once they get them but haven't find any where yet.

Thanks so much, Dave!! Sure thing--I have provided two more photos showing the location of the resistor. This is on the reverse-side of the board (side with WiFi chip), on the left-wing of the board (when battery connector is towards you/at-the-bottom). Let me know if these are still not good enough and I can take some more.

Just check with my working board the resistor is 15K.
