You can also inject the payload with TegraRCM. If you connect your switch to your pc and have TegraRCM started, you can check if the switch is in RCM.Should I Use a PC?

I am more familiar with PCShould I Use a PC?
You can connect your switch with usb C to usb A cable.only USB3.0?
Do you have a pc you can test it on?
Is the battery dead?
Is it your first time trying ever or is it just not working now?

You first need a way to enter RCM! You need something to bridge the Pins eg. Jig/Paperclip. Then Power your Switch off. Power your Switch On while holding the Vol + Button. If the Screen stays Black you can try to send a Payload either via Android or PC.

what are the steps you took? can you list them one by one?
