Hacking Question Temporarily load old NAND backup with too many efuses burnt?

ipkryss · Oct 15, 2018

My switch came with 4.01, which means 5 fuses burnt. As soon as I got it I took a full NAND backup via Hekate CTaer 3.0. I have never taken it online, always airplane mode.

Since then I have updated the firmware to 5.10, causing the 6th fuse to be burnt, rendering my old NAND backup useless(?).
I have also done a lot of stuff on my switch that will cause a ban as soon as I taken it online.

Looking forward I would love to be able to utilize future proper emuNAND solutions to take my switch online.

My question is: Is there a way to load this old NAND at least temporarily, upgrade it to the latest FW and start over from there? This way I could clean up my traces of homebrew. The bootloader should not allow to boot fw4.2 with 6 fuses burnt, but is there a way around this?

If you boot thru RCM, you'll bypass the fuse check.
So booting to Hekate, restoring the backup and choosing stock will allow you to boot normally.

Right, I see.. So I could restore nand, launch it from RCM and Hekate CTaer, update it.. and hope that these things does not leave any traces.

Maybe im not the only one with this issue and someone comes up with a method for this that makes it safe(r).

Exactly.
Restore -> boot thru RCM -> update

And then I guess it all comes down to how detectable one single RCM boot is for Nintendo. Maybe since I only boot it from RCM with update 4.01 (and not a later version), it may not send any data to Nintendo. I read that later versions include more data.

Apparently, hekate "masks" (or covers up, idk) that you are booting from RCM.
Don't quote me on that.

Well thats fucking great. Thanks for your info, as soon as there is a proper emuNAND out I will do this. I am not convinced to use the SX OS one yet.. I only get one chance for ban

I'm guessing after you boot in RCM and restore, you can update via gamecart to 5.1.0, then you would be able to boot normally. Don't quote me on this since I've never touched switch hacking.
