Now as a test-payload we will use biskeydump.bin which will dump your Switch’s device key. DO NOT under any circumstances share this key online.
Download biskeydump.bin from here (Just extract the zip file to get the .bin file). Copy the bin file next to TegraRcmSmash.exe. Now just drag and drop the biskeydump.bin file onto TegraRcmSmash.exe and see the magic happen on your Switch. To ease getting the keys and not having to manually write them on your PC the Screen shows a QR-Code. Just scan the QR-Code with your Phone and save the text generated from it in a Test file.
