That's correct, but you can't use anything higher than 6.1.0 with the guide you're following. You will temporarily have to downgrade to 6.1.0. Your Switch won't boot normally until you update to 8.1.0 afterwards.I have 10 burnt fuses, I have to update to 8.1 am I right? if I update to 6.1 I will have more burnt fuses then the right ones
