Alright. I have to completely rewrite this post after learning a lot from reading this topic and tinkering with the files.
The key to add a linked account offline is replacing contents in the
8000000000000010 file or the file itself.
The easiest method for doing this, especially considering the current state of Atmosphere emuMMC seems to be by using the KefirUpdater. You install it like any other homebrew, then with the press of a button it does everything automatically for you.
HOWEVER KefirUpdater is a closed source program with account info from someone you might not trust and therefore it's likely some will not prefer this method.
I've tried to tinker with KefirUpdater to see what it actually does and discovered the following:
- The program is downloading a zipfile called
su.zip containing the linked account files.
- It unzips these files to sdmc:/switch/kefirupdater/su
- Then it opens and save the
8000000000000010 and
8000000000000011 files. Injection happens here and I'm not sure what goes in 8000000000000011.
- Finally it reboots to RCM using the reebot to payload method. (At least that's what happens for me)
Furthermore I've tried to provide modified files manually but the program will always try to download the new files anyway.
These are the downloaded contents unzipped (same as post #88)
Code:
su/avators/*.jpg
su/avators/profiles.jpg
su/baas/*.dat
su/cache/
su/nas/**.dat
su/nas/**_id.token
su/nas/**_refresh.token
su/nas/**_user.json
su/registry.dat
* unique string generated only for this account
** another unique string generated only for this account
Lastly, a probable way to trick this program to use your own files would be spoofing the address it's looking for by making your custom DNS. But in that case it'd probably be easier to dump emuNAND, use hacdiskmount and recreate your emuMMC again.
