    What you need:
    And unused PC Power Extension cable such as this one.
    A cable cutter or a simple scissor.
    ~5 minutes of time.

    Steps:
    1. Cut off both ends of the cables
    2. cut off around 3-4 cm (1-1.4 inch) of one of the cables
    3. take the cutoff part and remove the a bit of the inuslation on both ends (~0.4cm or ~0,1 inch)
      Either use a cable cutter or use a scissor which you dont fully close, just enough to get through the insulation.
    4. twist the now lose cables on both ends together until they Form a decently solid "string"
    5. bend the cable in a u-form and put it in place, the switch joycon rail should hold the cable for you
    6. adjust the cable by pressing both ends towards the closest side of the rail.
    Dont worry if you mess up, you should have a dozen tries before you run out of cables ;)
    Pictures

    Troubleshooting:
    Pin 10 isn't shorted.
    -push the cable closer to the rail sometimes they seems to hit the empty space between them
    -try moving around the switch preferably so that gravity pulls the cable closer to the pin.

    Is there any indication if the switch is in rcm mode? Mine just doesn't work. It boots up normally into OS.
    How to enter the rcm mode correctly? Do I have to hold only "+" while powering on or do I need to hold power?

    I'm pretty sure I shorted PINs 9+10 and even PIN 1. Or do you have to short ONLY PIN10+1/9?

    I tried paper clips, wires. I have no clue why it doesn't work. Must the cable be connected BEFORE it gets into rcm mode else it will boot up normally?
    I have an USB type A to C cable but it clearly is a USB2.0 cable (missing 3.0 pins). It works for my 8bitdo controller (in USB-Mode) and I can charge other devices with it.

    Can someone help please?

    You shut down your console completely.
    You short pin 10 and 1.
    You press VOL- and hold it down (or was it VOL+?).
    You turn your switch on.
    If you see black screen (no light at all) instead of Switch logo, you are in RCM.

    PS: It should stay in the black screen for ever, not boot into the OS. There you can connect it to the USB and do further steps.

    Ok I've got it working. I just took a power cord (thicker cable) and only used one side to bridge PIN9+10. This worked immediatly. Seems that my paperclip/other cables either shorted too many pins or they are not pushed hard enough against the pins.

    Instead of pressing power you also just can insert the USB cable. If it doesn't turn on or show the battery icon it works. Also you device should detect it as an apx device

    Not forever... if you wait a couple minutes and try turning it back on - it’ll reboot unaffected (I think) - that’s what happened to me.

    Do I beed to cennect nx Switch to a PC in order to get to RCM mode ir should it work regardless and I made a mistake?

    What would happen if the wire touch the next pin? Those wire seem a bit big for the pin.

    Nothing. Even if you if you hit other pins it would be 9 and 2. All of them lead to ground

    Thanks OP, about to try this. Once you have entered RCM mode, do you need to remove the wire before you run the payload or is it ok to leave the wire connected to the pins?

    I tried many times and gave up lol. Then grabbed two small screwdrivers and joined pins 1 and 10. Bham! Worked first try.
