Hacking Question Accidentally updated switch while in EMUMMC but it DIDN’T update OFW of the system to 9.0?

Sejo · Sep 19, 2019

So I’m a bit confused what has happened.

I am on 8.10 and the next update would be 9.0. I was trying to start a game in EMUMMC too quick by pressing “A” and didn’t realize it asked me to “update” and I accepted the update .

I tried to stop it to no avail, then it rebooted and I was back in hekate menu. I had the option to run CFW (SYSNAND), CFW (EMUMMC) or Stock (SYSNAND), here’s a picture:

The only ones I could start were CFW (SYSNAND) and Stock (SYSNAND). When I tried to start CFW (EMUMMC) it just returned me to the hekate launch menu.

So then I started CFW (SYSNAND) and I noticed my Switch firmware said 8.1.0|MS 0.9.3|S.

When I turned of the system and went booted up the switch normally to check my firmware it stated was on 8.1.0...? I’m so confused.

Am I still on on 8.1.0 OFW Technically?

My EMUMMC shows that it’s still active and available:

So my question is, does anyone know what happened here? Was the EMUMCC only updated to 9.0 and since its not compatible with the hack it won’t start?

Is my EMUMMC salvageable? My saves if I didn’t save them via EdZion/Checkpoint?

I didn’t try putting my MicroSD card into my pc, but I’m sure I can still access my games / game saves from the partition.

Try to download the latest builds of Atmosphere (0.9.4) & Hekate (5.0.2).
0.9.3 & 5.0.1 are not compatible with 9.0.0.

Btw what happen if you try to load your emummc?
Blackscreen?

Atmosphere
Hekate
Atmosphere Sigpatches
Hekate Sigpatches

You are.
Just update Ams/hekate.

Atmosphere

Hekate Sigpatches

So I just download and drag/drop the newer ones into the partition and I should be able to launch my EMUMMC?

When I try to load/launch EMUMMC, it just starts loading it and immediately goes back to Hekate launch menu.

Can someone explain what happened with the update not updating OFW to 9.0? Was it because I was in EMUMMC and it saved my ass when the update happened?

Yeah that should work!
Just make sure to keep your emummc Folder and your hekate_ipl.ini from the bootloader Folder.

Stupid question, where are those usually located?

crazy_p · Sep 19, 2019

emummc & bootloader should both be on the Root of your SD Card. hekate_ipl.ini is inside your bootloader folder.

Thank you! Can’t wait to get back at my Switch.

Good luck!

Out of curiosity, why do I need to make a copy my EmuMMC if I’m not deleting it on the MicroSD card?

All I’m doing is dragging and dropping Atmosphere, Hekate, Atmosphere sig patches and Hekate sigpatches onto my MicroSD card. How will that affect the EmuMMC folder and the hekate_ipl.ini file?

Sorry for so many questions.

Nice to hear that everything is working fine. :grog:

I don't usually comment, i actually made an account just to say thank you, you saved me after i did the same, was on emummc, updated accidentally and hekate would just restart when i tried to launch cfw emummc, dragged and dropped all files mentioned (but for fw 9.1.0) and it worked. I also wanted to ask, since i updated from nintendo i am probably banned now right? And do i need to do anything regarding sysnand still being a earlier version than emummc? Thanks again.

Update your Atmosphere Build, there should be no titles Folder, it's now called contents.

Best would be to try a spare micro SD with only Atmosphere on it and formatted as Fat32.
Also make sure that you're really injecting the latest Fusee-Primary with TegraRCM, or whatever
you're using.

It sounds like he had only updated a game and not the firmware itself since he says his fw was still on 9.0.1 meaning he could still launch cfw and see his games had disappeared after updating which i don't think it would have launched if he had updated the fw. I'm far from an expert though but think you shouldn't have updated your ams build after this since your firmware is still 9.0.1 and updating your cfw made them incompatible causing that black screen, maybe try restoring the ams build for 9.0.1?

MasterJ360 · Jan 10, 2020

Also use incognito mode or use the 90DNS internet connection. It can prevent accidental updates
Also higher Atmosphere updates work for previous firmware. Its not firmware specific. Its hard to pinpoint the issue b/c some of it doesn't make any sense. Updating a game shouldn't cause his other games to disappear. Dealing with latest Atmo will require to delete old atmo and kosmos folders from your SD card. You cannot copy/paste them over the previous atmo you had or it will cause errors.

I think it was the system firmware ,it said system update and i was in a panic i took out the ethernet cable from our modem! not liked it helped as it restarted ,but still had the theme on but my games were all gone ,when i checked the system software it still says 9.0.1,so i tried to follow what sej did but when i try to launch cfw emummc its just a black screen,tried to launch the fusee primary but it goes blank after the nintendo logo.

When you say update my atmosphere build does that mean delete the atmosphere folder completely and paste the latest one?im using an rcm loader which i did not update by the way ,could that be the problem?i put all the new updates of atmosphere amd hekate on the sd card but just copy and paste it and replace all the previous ones.Thank you so much for replying ,this is doing my head in

Now im a bit confused should i have not written over the atmosphere and hekate folders ,will need to check what else i written over ,at first i could launch into cfw but not the emummc ,but when i download the latest updates for atmosphere and hekate thats when i couldnt launch cfw anymore

So what should i do now?should i just wipe the sd card and start from scratch?i mean its ok for me its just that i dont evem know where to start,all im thinking is reformat the card to fat32 as it on exfat ,that wipes out wvwrything ,then put all the necessary files in the sd ,does that also mean that i download the latest updatea for the rcm dongle?

Overwriting should be fine. Make sure you also update the sig patches.
