How to Hard reset CCR1009-8G-1S-PC in case the Reset button is damaged.
Can I short the circuit at which pin? (As per the attached image)
Thank You.

Check with a ohmmeter, but 1 and 2 should be connected directly (0 ohm) and as well 3 and 4.
So shorting 1 and 3 or 2 and 4 should be the same and initiate the reset.
The original button should be similar to this one:

Thank you very much. jaclaz I will try to test it. How it works will be reported again.

Yep, those kind of press switch buttons have only one contact, normally open, many have consequently just two terminals, while others (particularly the ones that are intended for side-push) may have four terminals, but they are (internally) two couples, this is essentially only because four solder points make the component more stable/better fixed to the PCB.
Then the PCB may have all four contacts connected as two couples, or only two connected and the other two only as solder points connected to nothing.
Anyway the symbols on the PCB seem clear enough in your case, checking with the ohmmeter is only "good practice", rendered as "ascii art"

Thanks for this thread, it helped me out.

I can confirm shorting out 1-3 (the two on the left) did the trick for me. I assume 2-4 does the same.

I ended up drilling out the reset hole so i can get my tweasers in via the front rather than take the whole board out. It can be quite tricky to make good contact whilst plugging in the power. It took me severals attempts but i got there in the end. Remember, keep contact and the green light should flash for a while, release when it stops flashing.
