Hacking How to use emummc to update from 3.0.0?

[bobovieri]

I have a switch on 3.0.0
I do not want to update it, but I want to update my emummc which I created with Hekate 5.0.0
I can launch the CFW (emummc) option and I'm in the switch main menu, I can launch homebrew etc.
If I look at the system info my current version is 3.0.0 (AMS 0.9.2)

Now ideally I would like to update the emummc to the latest version, so I could read there 8.1.0(AMS 0.9.2)
I do not want to update my switch, which I would like to keep to 3.0.0
I do not want to burn any fuse.

I hope I understand correctly and I can do that.
But how should I do that?
Can somebody help me?

I have the same questions. If I create a emuMMC and update her to the last firmware, the fuses will be burn?

 

[Zuzuooloo]

My Switch sysnand is still on 3.0.0 firmware. My emummc is on 8.0.1. I don't believe any fuses have been burnt because I accidentally loaded up my sysnand fine. I may be wrong though.

The process is simple.
Load up hekate, load up emummc, use choidujournx to update from 3.0.0 to 8.1 (turn off autorcm, you also need to download the update file from that site). Emummc will then be on 8.1, with sysnand still on 3.0.0

Hey thanks for the help Zuzuooloo!

So just to recap n make sure I understand you correctly:
by using choidujournx to update emummc fro 3 to 8, when I will turn on my switch without any hack it will be 3.0.0, and if I will launch CFW emummc from hekate it will be 8.etc, correct?
All without any burned fuses?

So I updated my emunand to 8.1.0 and enabled autoRCM, I dont want to play online, just keep my sysnand in the lowest firmware possible. I need to do a backup of my emunand in case of a accidentally burn my fuses? I'm confused.

EDIT: Nevermind, I got de idea now, it's not possible to burn the fuses if I keep sysnand on the lowest firmware.

Hey Janio, thanks for the update.
So can you tell me how did you update the emunand?
Did you use choidujournx like Zuzuooloo said?
He said to not enable autorcm, why did you do it?
If you boot up without any exploit, do you have the system at 3.0.0 (or whatever is your low firmware)?

1. you just need to make sure never update the sysnand to avoid burn fuses and since the fuse count matches the firmware version (3.0.0) autorcm isn't needed so u can boot up without a dongle or jig then you activate the warmboot to access cfw and emummc 8.1
2. update emummc using choidujournx to be safe and not burn fuse
3, but it also re-enables autorcm

Thanks PCwizard7, but I still don't get the exact order here.
your "3, but it also re enables autorcm" doesn't compute here.
Like you said, autorcm is for booting without dongle.
I don't want it, I'm fine with using my paperclip every time.
Does choidujournx NEED autorcm? If so, why? Can I switch it off?

ChoiDujourNX enables AutoRCM by default, I'm not sure if there's a way to turn that off but you can always disable AutoRCM afterwards. I think you can use Hekate to do that.

this is what 3 mean't. now as long as you keep your sysnand on 3.0 you won't need a paper clip or dongle. the warmboot exploit allows you to boot into cfw or emummc without the need for a paper clip or dongle

1 question: Yes I used choidujournx, its a pretty simple process.

2 question: I enabled for extra precaution, but isnt necessary, I already disabled it.

3 question: When I boot without any exploit, my switch boot into original sysnand (6.0.1), so its impossible to burn fuses.

Choidujournx let you enable or disable autoRCM during the update process, you can also choose in Hekate.

Sorry for my bad english.

Awesome, thanks for the help!

Is it possible to update the emummc firmware on an ipatched switch? It looks like I can follow the normal tutorial and just make sure I disable AutoRCM within ChoiDujourNX when installing the firmware file.

Ipatched switch
OFW 4.1.0
CFW 4.1.0 (Atmostphere 0.9.2)
Hekate 5.0.0

That is the purpose of emuMMC; to have an updated firmware without updating the firmware of the console (sysMMC).
