Could you tell me which resistors need replacing? This is my current setup. I already found the clk to have a 0 ohm resistor and replaced it with a 47 ohm one. Do I just replace the dat0 resistor with 100 ohm?
I've seen these boards with higher resistance on dat0 lately, like yours which seems to have a 250 ohm resistor? Then changing to a 100 ohm won't help you. I'm thinking it's more likely that the the flex cable itself is the source of the problem, as it adds a lot of wire length to the emmc with not very good signal separation. I guess you can try adding even more resistance to dat0, but otherwise replacing the entire chip might be your only option.
