DBI asking for prod.keys

[The Real Jdbye]

I'll check Nx-update and about BigOnYa's question, I did answer it but for some reason the message is under moderation.
I said I used that version and the file that had "hekate" in it.

I see, I wanted to find something that can automate it.



It just my monkey brain telling me "you have to keep everything update :3" but I guess I should get used to not care about updates that much.

You will never have everything up to date, the latest updates are often not even dumped, so that's a losing battle. Just look for updates occasionally and be happy with whatever you get.

I'm having some issues using DBI.
Every time i run it, I get this error:
View attachment 546636

I googled it and translated it, and for what I understood I had to use Lockpick_RCM to creat the prod.keys file.
This is the report of Lockpick:
View attachment 546637

The file is already in switch/prod.keys but I still get that error.
And I don't know how to fix it.

My concern is on my Switch.
I bought a Modded but banned Motherboard on Aliexpress and swapped it.
This moderboard has a fake Serial number.
Since it was banned I didn't put the emunand, I'm running everything on syscfw.
Thank you all in advance.

Run Hekate's fix archive bit on the sd card

That is not accurate. The latest updates are usually dumped quite quickly, a lot of time the same or next day.

Thank you all for the reply and suggestions!

I was thinking about the situation with DBI.
I think I can start to care to update only what needed as said by @Earthshine.
But what I liked a lot with DBI was the MTP mount, where I could install games, browse the SD and copy/paste save files.
Is there a good alternative for this MTP function?

EDIT:
I found sphaira that has a good MTP for installing game and browsing the sdcard.
But, Still I haven't found a good homebrew for the save files. Does anyone has a good suggestion for that?
Because if I find something good for the save files too then I don't need DBI at all.

I tried for the records, but no luck.

Hi OP.
I have exactly the same situation as you.

Switch Erista V1 RCM Exploit (Unpatched)
I received the console in a bricked state, without a backup and without the PRODINFO partition.

I restored the OS using NAND FIX PRO with a donor Prodinfo provided in Sthetix’s guide.
The console boots and works on 21.1.0.
I’m running from SysNAND (a ban is not a concern, online doesn’t work anyway).

When I launch LockPick_RCM, I get the exact same errors:

SSL keypair has invalid GMac
Unable to derive SSL Key
Invalid eTicket keypair
Unable to derive titlekeys

When I open DBI, I get the same message saying that keys are missing.
Any game launched from a cartridge or installed via DBI causes the console to freeze completely.

Other people who used the same NAND restoration guide do not report this issue, so this seems to be a problem specific to my console.

Is there anyone who understands well how the key dumping process in LockPick works?
SSL keypair has invalid GMac
What exactly does this line mean?
Which key pairs are being compared to produce this error?
Could there be some chip inside the console that stores this key and is now dead?
Or does this key depend on the contents of the NAND and the PRODINFO partition?

Have you managed to run games in any way despite this?

Not a helpful post, but just wanted to say I also have this 'issue'...not really an issue though, plenty of alternative workarounds.
I'm in the same boat, I have a Switch Lite that was internal NAND corrupted due to overclocking, and I had no prodinfo or any backups at all. Also used the NAND restoration guide from sthetix to generate fake info all around to get a working system again with all donor info/keys.

So it seems here DBI doesn't like the donor keys and or any files generated from having a donor system in the first place.

Please read Lockpicks's readme file:

Mariko-Specific Keys​

Mariko consoles have several unique keys and protected keyslots. To get your SBK or the Mariko specific keys, you will need to use the /switch/partialaes.keys file along with a brute forcing tool such as https://files.sshnuke.net/PartialAesKeyCrack.zip. The contents of this file are the keyslot number followed by the result of that keyslot encrypting 16 null bytes. With the tool linked above, enter them in sequence for a given keyslot you want the contents of, for example: PartialAesKeyCrack.exe <num1> <num2> <num3> <num4> with the --numthreads=N where N is the number of threads you can dedicate to the brute force.

JKSV is way better than DBI. You can even use the cloud for saving and restoring your savegame files.

When using the Russian version 863 on an Erista with CFW 20.2.0 and ATM 1.10.2 this message appears.

Nothing with DBI 854.ru

 

[duckbill007]

It is correct. 854 has less checks and in case of some missing keys it allows some operations but due to missing keys produces garbage or incorrect behaviour. 863 has aditional checks and reports what keys are missing.

After using the latest version of lockpick_RCM.bin, 863.ru no longer displays the warning message.

Thank you.
