hello did u use a 10 ~ 50 ohm for the dat0 when using the core?

I didn't, I was using the old guide which worked before.
I just bought some resistors and will put on my setup.

but I think my 4th switch has a bad trace for idk reasons, I removed a wires and I still get purple screen. 3rd switch was the same but miraculously it worked after repeating everything.

also I managed to fix the 3rd, I did some tests and I made the clk very very short. it's tricky to make that loop around the heatsink. also I twisted my clk wires twice for the thickness and signal strength and now no more block read error and ofw boots on switch #3

now I have to get testing with switch #4, hopefully the resistor will help. I purchased 10,30,50 and will check which one works best

seems to not improve at all, now have a resistor, I managed to recover from the purple screen.

it seems the cmd line is very sensitive. if you managed to dislocate its soldering, it could result in a purple screen, also the clk line.
one switch oled I had 5th one, it would get block read errors, I shortened the clk wire and the error went away.

this is what I was using.

Please try to use the UL10064 wires, 36AWG

thanks @sthetix
I used a thicker wire like you said and it never happened again.
I also would like to add that clk and cmd points matter a lot.

the lite version seem to work better than the core (hwfly) on using with THE OLED

btw, it would be great if you can produce video guides on internal installs on unpatched marikos using the prevalent RCM dongles like this
