Hacking ChoiDuJour EmuNand backup problem ?

Deleted member 514389 · Apr 16, 2020

First off:
This is not a thread à "I f+++ed up, pls help".
I was able to reflash my 9.2.0 Backup and my EmuNand in the switch is happily working again.

However
This is a Why did ChoiDuJour f*** up my Emunand while trying to update ?!?!" - thread.
[Alternatively this might be a /why did *I* fail/ thread, but who knows.]

Breakdown
EmuNand upgrade attempt: 9.2.0 -> 10.0
a) selected folder /game/update/fw10
(with *.nca files insed for fw 10.0)
b) updated (selected the left option as I'm not using ExFat)

** My Switch wouldn't boot up in Emumand anymore (Blackscreen after Atmophere logo)
[Normal Sysnand parition is -ofcourse- unaffected, boots as if nothing happened, no further efuses burnt either.]

I attached the screenshots I took while running it, it reported some errors, so maybe I did something wrong

Ideas ?

PS: yes I did copy the new atmosphere files (compatible with 10.0 over).
And no, I currently do *not* care so much about sigpatches or w.e. (even though they apparantly exist...)

Using ChoiDuJour 1.02 from the official site + recopying Atmosphere to the MicroSD again
+ recopying the fusee-gelee.bin payload to the RCM-Dongle again
=> WORKS

Possible explanation would be either you used a bad firmware update files, or you didn't properly updated/configured your CFW to Atmosphere 0.11.1 for it properly to work.

did you update your sd files?

go here to grab all update files and select kosmos defaults then feel free to select things you wish to add to it
http://sdsetup.com/console?switch

then you need to update hekate and atmos so once you have the above on the sd card then overwrite files with these updates
https://github.com/Atmosphere-NX/Atmosphere/releases/latest
https://github.com/CTCaer/hekate/releases/latest

PS

Reminder for EVERY HOS update:
- Always check for new cfw updates in the first days. Bugs are normally ironed out timely.
- Run both archive bit options in hekate
- Delete custom themes
- Delete incompatible sysmodules
- Keep an eye on devs updating their hb apps

i’m having exactly the same problem..

after following your suggestions pcwizard7, I can now get the system to boot using hekate, but after 2 seconds I get Atmosphere Error:
2168-0002 (0x4a8)

Injecting Fusee-Primary rather than Hekate still gives me a black screen after the Atmosphere screen.

any ideas would be appreciated!

EDIT: following the advice on other threads, this solved the issue: https://github.com/borntohonk/NEUTOS/releases/tag/0.11.1-NEUTOS

@pcwizard7
Looking good, will take a gander.

@Beetlebum89
So update via choi. and then use neutos atmo fork ?

Thats it ?

Whats so special about Neutos ?

PS: Are the update files region specific (US/EU/JPN) or universal ?
I suppose they work across the board ?

Edit:
Updated Atmosphere and Hekate via AtmosUpdater.nro,
prior to trying Choi. and FW 10.0 Upgrade
=> same result as last time, no more boot

Tried suggested alt. FW:
=> Same result...

I'm starting to wonder whether or not my FW 10. files are somehow botched...

EDIT2:
I just noticed that people usually have exFAT microSD's and appropriately select Choi's ExFat option...

As my microSD is in FAT32 (as suggested all over the internet) I always choose the left otption.
Is that a problem perhaps ?

Finally it works

1) Using ChoiDuJour V 1.02 finally wrote the Emunand FW 10.0 correctly.
(Now however Atmosphere spouts a nice crash on boot...)
2) Replace the "atmosphere" "sept" folder with a new one
3) replace the payload on my rcm dongle with the new fusee-gelee one
=>
F-I-N-A-L-L-Y 10.0 on EmuNand, sweet

Thanks for all the help ppl
