Would you show me yours?

Use hard surface and steady hand, it cuts like cheese

This is also my preferred way now

Hi. I have just received the rp2040 tiny. I am aware that i should remove the resistors because they have put there ones with 470 ohm instead of 47 and then add those to the board. Is there any other issue regarding the board? I get that the firmware is compatible and there is no other issue?

I have used the search and found nothing else related with that board but as it is not on the guide...

No other known issue. You could measure the resistors on board just in case you got lucky and received the revised version with correct resistors
Also, if you remove them, don't forget to bridge the connections once they are gone.

Nop, 470 ohm confirmed. The one for pin 29 is 1kohm. Regarding the firmware i don't need to brindge any pin for the software to "detect" the board?

Just assembled my first rp2040-zero in oled, everything went ok but when I turn off the switch I can't turn it on. I need to disconnect the battery and after a few minutes I can turn it on. What can that be?

You only need to remove/replace the ones in red

Which size of magnetic wire is recommended? 0.1mm? 0.2mm? I’m using “regular” wire AWG36 for everything, should I use thicker wire or this size is fine?

Thank you in advanced.

Do you get any light? Check the white ffc cable, and the USBC to PC cable aswell

yes, on the usb board i get the power light, in red. i will try with another cable...

That should work and 0.2mm (32awg) for mosfets.
The best would be to read the guide by lightninjay before you move forward: https://gbatemp.net/download/a-definitive-picofly-install-guide.37968/download

It seems I can't flsh the firmware. I keep getting this error... any idea of the problem?

I am able to flash the flash_nuke.uf2 so could it be something related with the 2.73 firmware? where can I get older versions?

Seems to be usb controller issue.
Can you try on different pc? Also try disabling antivirus.
You could also try reinstalling the USB Storage controllers from Device Manager.

I figured it out. The ffc cable does not fit properly in the conectors... Thank you very much anyways!

Now ur getting dirty here ....you show me yours I'll show u mine .....Hahahahahahaha

But scissors is the cleanest way to go if u have the disk cutter it also gives a clean cut , but I still need to sand on the bottum side of the cut

Yeah that cable is not wide enough, you have to slot it in just right
