okay so I wanna update for the online stuff and want to make sure I have everything so I can downgrade if I need to. I have a raw emmc but it's in bits,how do I unite them? is the emmc dump all that is needed?
EDIT: I am on 5.0.2 sorry for confusion.

it is, the 5.1.0 does not burn efuses.
to 5.0.0 yeah but there's literally no point in downgrading to that version, also you would have needed to make a backup of your system on that previous version.

every major version burns a fuse. so you cannot go lower that 5.0.0 when you are on 5.1.0

It'sa nand restore not downgrading.
The nand restore becomes a downgrade if he do the update to 5.1.0 before that.

I don't think that this all is a good idea. What if nintendont keeps track which device is at which fw state and could easily tell that this particular device has now a lower fw it had before?
It's potentially as dangerous as messing around with their CDN in my opinion.

Why?

There is 0 logical need for this. Why do you want to do it? What is the actual need for such a thing? Are you doing it just for shits and giggles?

You have a 5.0.2 backup and a 5.1.0 console. Explain to me why do you NEED to downgrade, because right now there is no logical need to do such a task.

Updates also happen from carts which Nintendo has no way of detecting. they could log an OTA update and then log a 2nd one for ban. I'm pretty sure they wouldn't go through the trouble.

Thinking about it as a console company and a developer results in: "there is no trouble"
Your console pings N servers which then authenticate you anyway. They see you have version X and announce this to some backend system that keeps a super simple DB of sold console SN's and FW versions.
If you authenticate with a lower FW than saved you get flagged. There is nothing hard or difficult connected.

The big plus for N is that they have an easy way to keep track of overall FW statistics and collect ban flags...
