All jokes aside, this completely defeats the only one left purpose of SX-OS. :bow:
will it be possible to load xcis?

also im not so familiar with emunand on switch, i did use it on 3ds to play online.
but what is the purpose of it on a switch?

also it'd be super nice to coldboot into cfw.

Sorry, im not installing anything on my Switch, not even on EmuNAND, XCI all the way.
xcis are nice because its easy to use them , no need to install ,reminds me of .3ds instead of cia.

but i usually only have the bigger games in xci formate (i own a 200gb micro sd and have it nearly filled up with nsps) and have around 30gb remaining, i have around 12 games in xci format and i damn sure cant fit even half of them on my 200gb card.

each of those games is like 14gb in size +3gb of their updates, that is 17!

edit : shoot , sorry double post, thought there were already replies after mine.

EmuNAND has nothing to do with loading .XCI files. But its looking like free CFW will never receive the ability to mount .XCI files like SX OS so TX will always have that trump card similar to how Gateway and other 3DS flashcarts were the only to play .3DS/.3DZ titles.

Anyway, point of EmuNAND is the same as it was on the 3DS; you use it to load a higher firmware without updating the firmware of your SysNAND. This was pivotal in the 3DS scene because Gateway didn't work past firmware 9.2 so there was no way to play online and retain Gateway without EmuNAND. On the Switch, this isn't as necessary since the exploit we have works on all firmware versions. For patched units however, EmuNAND is going to be the only way for them to be on a firmware higher than 7.X whilst retaining CFW so if you want to play online with a hacked patched unit, EmuNAND is a must. And I guess you could also use EmuNAND as a way to keep CFW and homebrew separate from your legitimate online usage.

By the way, EmuNAND itself also has nothing to do with coldboot. Its like a CFW, it can be either coldbooted or warmbooted.

thx nice explanation, but they say you might still get banned even if you used sysnand (original copy of game) etc.
unless you have a super clean backup or soemthing , which i personally dont.

but i dont care much about playing online, and if one is banned what do you lose exactly apart from not being able to use 'eshop' or playing 'online' ?
(because i had my switch hacked since like day 1, a year ago and i am still not banned, i still open eshop at times within sx os OFW option)

Exactly, EmuNAND isn't going to save you if you don't have a clean SysNAND, or backup, in the first place.

And it depends on the ban as there are multiple types of bans but the most common one prevents you from using the eShop, online play, and potentially game updates (jury is out on this as there are conflicting reports on this phenomenon). You can read about the various Switch bans in my thread.

so if i am not intending to play online or do not care about online stuff, then i dont need emunand?
or would emunand still be necessary if i wanted a coldboot feature?

i like the idea of being able to turn off my switch any time and not need to send any payload and shit in order to get into cfw,not needing otg cable or any dongles (i currently use an otg cable with my phone to send payloads) or usb c with latptop.

it'd be dang sweet, let me know if emunand is needed for coldboot. (and also is this thing in the thread something about coldboot feature besides emunand?)

Second i didnt question the importance of emunand.. I just said that before every user of atmos said it was an unwanted feature.. But then when atmos say that they now are working on it . its suddenly a nedded and important.
Thats the hypocrisy.
That was sudden...

The purpose of EmuNAND was not originally to be a ban shield. Like I said, EmuNAND is a way to update your firmware without updating SysNAND. For unpatched units, this means you can update your firmware without burning fuses or relying on AutoRCM. For patched units, it is the only way to update your system past 7.X which is the highest firmware Deja Vu supports which is the only way for patched units to load CFW.

And by coldboot, I assume you mean untethered but either way EmuNAND has absolutely nothing to do with coldboot. EmuNAND is another way of booting CFW. You would need a way to boot it which would be another exploit. The only way EmuNAND would matter in the case of an untethered coldboot exploit is if that exploit only works on a certain firmware version meaning booting EmuNAND is the only way you would retain the exploit while being able to load higher firmware versions than the exploit supports.

Your patience explaining the same thing that's been asked over and over again is inspiring - keep it up!

Regarding the low-enoguh-FW for a coldboot: what's the highest FW supported for that?
How do I find out the FW my NAND backup was made on?

This is where we get into theoreticals. SciresM made a post last year explaining the best firmware to get untethered coldboot is up to 3.0.1 however no one is working on it (he even has a bounty set up for it just to indicate how challenging it is). Technically, there may be an undiscovered coldboot exploit that works on higher firmware versions or all of them but the chances for this are slim to none. This is generally why the lower your firmware version, the better. I should also point out that its not the firmware version that is important here but the fuse count because if your fuse count exceeds the firmware version you are trying to boot, you will not be able to boot that firmware. I am also pointing this out because some people have very low fuse counts but are on the latest firmware so they can take advantage of an untethered coldboot exploit if its released on a very low firmware version.

As for checking the firmware of your NAND dump, you can use Firmware Version Inspector

That's why I'm asking for the NAND Backup FW.
Once emuNAND is out, I want to have a "clean" SysNAND (hence the backup) and a CFW emuNAND.
As far my understanding goes, for this I need to
  • Revert my current FW (installed with CoiJou... without burning fuses) to the one matching my NAND Backup
  • Then "install" my backup
  • Then officially updating through Nintendo (I have an unpached unit)
  • Then I can use SysNAND on highest FW for online play and emuNAND for homebrews (on any desired FW - because I can bypass fusecounting on CFW)
Did I get that correctly?

/Edit: what backups will I have to rewrite? As far as I remember I only backed up NAND, maybe also boot, but it's been pretty long time since then, I can hardly remember...

Well downgrading before your backup is pointless since your NAND backup will end up downgrading your firmware. In fact, downgrading with a NAND backup is better than downgrading with ChoiDujour/ChoiDujourNX.

As for updating your firmware, I always try to urge people to update without burning fuses even if there may be an inherent ban risk in doing so even though no one has been banned for only having a fuse mismatch (or AutoRCM for that matter). But if you're content with the current exploit and/or don't care for any other exploits, then you can just burn fuses by updating online. Otherwise, you can use ChoiDujourNX to update without burning fuses or if you're feeling risky, manually enter RCM after performing a system update by having your jig inserted and holding volume + when the system reboots.

I'll just quote myself
But before that.

I think it is valid to call you a moron. Especially when your first word is fist.
You're a moron. The only reason why atmosphere has just now given support to it or started to is because they had different priorities, targeting on a replaceable module system and getting homebrew to more than just function. And then add emunand. We wanted it but understood it was not immediate priority for the team.
I think I rest my case.

Interesting. First time hearing about no one being banned so far for fuse mismatch/RCM mode online - sounds promising...
Even though I'm still inclined to having a "100% >legal<" (normal online update), that would mean I'd have to buy some jig since I've been using a self made one made of a paperclip xD

/Edit: what backups will I have to rewrite? As far as I remember I only backed up NAND, maybe also boot, but it's been pretty long time since then, I can hardly remember...

Any info on that?

A full NAND dump comprises of BOOT0/BOOT1 as well as the eMMC raw GPP. eMMC SYS can be substituted for eMMC raw GPP at the cost of any save data or installed content since those are found in eMMC USER (eMMC raw GPP is comprised of both eMMC SYS and USER). You need BOOT0/BOOT1 if your current firmware does not match the firmware of your eMMC raw GPP/eMMC SYS and consequently, BOOT0/BOOT1 should match the firmware of your eMMC raw GPP/eMMC SYS; it won't do you any good to have a random BOOT0/BOOT1 and eMMC raw GPP/eMMC SYS. If you have an eMMC raw GPP/eMMC SYS, you can generate a corresponding BOOT0/BOOT1 with ChoiDujour if you know the firmware of your NAND dump but keep in mind ChoiDujour only supports up to firmware 6.1. If your eMMC raw GPP/eMMC SYS has a firmware above 6.1 but you do not have a matching BOOT0/BOOT1, you will have to use mattytrog's custom Hekate to restore a smaller BOOT0/BOOT1 that he made which we cannot link here (but can be found on xbins).

For those who are planning on grabbing bigger SD cards for emuNAND, just a reminder to always watch for a fraudulent SD cards!

There's a large number of us who haven't seriously delved into CFW because there was no real emunand option.
