No sciresm has said that he has achieved trustzone execution up to and including 4. 1 which means cold boot for custom firmware.Yeah, I think it's up to 3.0.1 only.
It's a shame because my Switch came with 3.0.2
Now all that is left for me is to wait for software hacks that exists up to 4.1 only as far as we know.
Trustzone exploitation =/= coldboot. The Trustzone exploitation SciresM is referring to is Deja Vu as seen below:

Anyway, I would strongly recommend not updating when new firmwares release.
As you can tell, this is a warmboot and not a coldboot.
It's my understanding anything past 3.0/3.0.1 or whatever will never get coldboot. ever. At the very most we get warmboot maybe eventually.Coldboot?

You can skip the nand backup part if you already have one!
You can downgrade to 3.0.1 and you don't even have to use AutoRCM as 3.0.1 and 3.0.2 use the same efuse count.Yeah, I think it's up to 3.0.1 only.
It's a shame because my Switch came with 3.0.2

Once Emunand is released I will downgrade as I'm also on 3.0.2, but my Mario Odyssey cartridge requires 3.0.2 for now.
The first tutorial makes it look way harder than it actually is, there are only 18 small steps.

I'm not sure if this downgrade method will work the way you think when it comes to exploiting. Can you really do downgrade 3.0.2 to 3.0.1 and never have to use hacks to boot?
As for Mario Odyssey: it can be played on 3.0.1, as it requires >= 3.0.1
Yes, you can also downgrade from 5.1.0 to 5.0.0 as they require the same amount of fuses.

My Odyssey cart is v001 so it requires 3.0.2 instead of 3.0.1, it's very recently purchased.
You need hacks to restore a NAND backup. But since the stock firmware of your console was 3.0.2, where do you want to get a 3.0.1 NAND backup which you can restore?
