Are there any tools and/or tutorials yet on backing up the NAND in recovery mode? I want to make that the first thing I do on a new system.
Nope. Not yet. But I can see them coming even from SciresM him self in the future
For Now, you have to create payload that can do it :D

Wouldn't that be possible to access eMMC from Linux running on switch and create dump of eMMC easily ? (considering we will get keyboard working under switch)
I'm currently looking at possibilities.

I would assume you could at least do a basic image of the eMMC from Linux using dd, that doesn't require being able to mount any of the partitions.

Hence we know all the keys and got tools we can extract and decrypt partitions from raw dump. Am I wrong ? ;-)

I dont know if linux have acces to nand (probably has), so.. maybe?

It should be detected as standard block device under linux without any special drivers...

I can't wait to get huge 32GB dumps of my nand. Ah yeah, time to find another hard drive.

Ima make a backup every week just in case. /s

Yeah, I need to make some purchases soon. Bigger SD, better reader, SNS-30 Pro (I like my SNES controllers and my d-pads. and my cables).

The nand itself is 2.7gb is this what's you're saying? Hope so, a 32gb emunand is going to kill even big SD cards.

The NAND itself is 32GB. As it's likely it's encrypted without privileged access to the HorizonOS we're going to get only raw NAND dump which is 32GB. The HOS partition might be 2.7 GB but there is no was to get it without proper dumper payload - yet.

We can already dump individual partitions via pegaswitch.

Lucky you then. I can't. I'm on 3.0.1. Unless you give me the payload to execute the pegaswitch from FG vector I'm only able to dump whole NAND via Linux and decrypt/get individual partitions that way.
