Hacking Hardware Switch OLED rp2040 blue screen

I tried to install rp2040 picofly with flex cables. Did testing with multimeter don't know if everything is ok.
Here are the readings:
3.3 - 0.936
B - 1.573
D - 0.730
Clk - 0.728
C - 0.718

But I when I tried for the first time I knocked off the resistor near D point. Reading the forum I thought it was 4.7k om. So I managed to get other one and install it. The reading before chip install was 0.7, now after chip install the resistor shows me it's 2.518, but D point still 0.73.

4.7k ohm is referred to the resistor blue pointed, and 47k ohm next to it(which you should not bridge to the A point).

Thanks for the quick reply, when I posted I saw on the photo that I soldered wrong and I corrected it. Other question do you know the value of this resistor in red circle near point D? Because on some thread I read it was 4.7k, on other that it is 100r ohm

that's 100 ohm

that's 100 ohm

Thank you for your quick response. I'll order 0201 100r from Ali
