Hacking Manually updating romfs.bin for backups

[Zumoly]

Yeah but you have to follow a WHOLE procedure to get them out of the SD card in the right format.. Is not so easy as copy and paste xD

Oh I see. I sure hope we'll get a tool to directly download them off Nintendo's server.

Problem is they need to be decrypted first.

Yeah that's right! I guess that's why we need the title keys.

How or where can i find updates?

Tried it with Splatoon 2, works with update nca but not with Octo expansion nca.

That's interesting! Let me try something I've been thinking of for the Octo expansion...oh wait I have the card game.

And if i want to get the titlekey my own, how do i install pycrypto ? It never works for me

Did you first update and tried merge Octo with updated game ?

Input:
hactool -k keys.txt --titlekey=49C2C*******************D1BC4 --basenca="xenoblade.nca" --section1="done\romsfs.bin" --exefsdir="done\exefs" "xenodlc1.nca"

Output:
Section 1:

BKTR section seems to be corrupted.​

Error: section 0 is corrupted!

Saving Section 1 to done\romsfs.bin...
Size: 000000000000
Error: section 1 is corrupted!

"xenoblade.nca" need be decrypted (games from cartridge are always decrypted, but eshop games not), if it's already, you aren't with correct title key for the update

not sure how to do that exactly...
decrypt so i end up with romfs.bin and exefs? or how would i do that?

sorry I'm wrong, you dont need decrypted file, I just tried again with Arms (encrypted)...
you just need the correct titlekey for the update....

Common tickets (a.k.a. cetks) can be downloaded from atum.
Simply send a certified HEAD request to https://atum.hac.lp1.d4c.nintendo.net/r/t/ (Update Rights ID, eg Super Mario Odyssey version 1.2.0 update: 01000000000108000000000000000004)
Then send a certified GET request to https://atum.hac.lp1.d4c.nintendo.net/c/t/ (X-Nintendo-Content-ID value returned from HEAD request)
I strongly recommend you use the extended User-Agent header which gets generated by the snprintf function in NIM.

Actually Octo includes the latest update plus some additional bytes for new characters, weapons etc. If you try to to merge Octo into already updated romfs I'm pretty sure it'll fail to boot.

Common key ? Did you mean title key ?

 

[huma_dawii]

Titlekey, and yes the one he game me that is the title key, what I don't get is, why my title key was different?
