Hacking NTRBootHax vs Bricked N3DS, help required

[Cuphat]

Maybe you can try to boot an emunand...

If he had a usable EmuNAND, he could have already restored that to SysNAND.

The problem is that the N3DS downgrade to 2.1 does weird voodoo bullshit to the NAND to make it work that is apparently not undone by GodMode9.

I'm not sure why Decrypt9 isn't working, but it sounds like d0k3 is working on allowing GodMode9 to fix this issue.

What did you do exactly just for future reference

The magic was putting all the keys into the files9 folder.

But we're not out of the woods yet. Autofix CTRNAND throws an error in my face, currently using the Auto Restore, we'll see how that goes.

I just looked through the source and it looks like should it fail to auto-fix, we can do a manual fix any way. Just need to recalculate the CMACs on the required files and rename the id0 folder to match that of your 3DS, which we can do all from GodMode9. Also, those slot keys are copyright, so may want to remove the link from your post and just say you needed all the slot keys instead of the compiled aeskeysdb.

Aaaand, "Auto CTRNAND Transfer: failed!"
Apparently it can't find SecureInfo_A?
Would "Forced CTRNAND Transfer" work?

Hey thanks for those keys boi been lookin for those

Link removed, but the further steps I'm gonna need some help with. Exactly what should I do in layman's terms? What are the required files and how do I recalculate them CMACs? Where is id0 and what exactly do I rename it to?

 

[DocKlokMan]

Let's try and do a manual fix. Boot into GodMode9. First, go to your SD > Nintendo 3DS folder. You should have a folder in there with a long name of alpha numeric characters. Post it here, it's not personal or anything.

 

[eworm]

...
Huh.
Somehow I didn't realize that my Nintendo 3DS folder is empty. I dunno what happened to the "random sequence of numbers and letters folder", but that might explain some of the issues, probably.

I don't actually think it means anything

Damn, alright, well let's try fixing some files and see if the ID0 is fine. In GodMode9 go to 1:\dbs\ and press A on each of the files there and choose Calculate CMAC. If any say they don't match confirm to fix them. Once all of the files in there are recalculated try and see if it boots.

EDIT: Oops, also go to 1:\private\ and run the CMAC fix on movable.sed too.

 

[jimmyj]

not gonna interfere sorry

 

[eworm]

All the files passed without the need for fixing, booting doesn't work. But I wouldn't be surprised if some were just plain missing. Should anything besides certs.db, import.db, ticket.db, title.db, tmp_i.db and tmp_t.db be here?
No, I didn't ttry the forced transfer. Should I?

I edited my post above because I did not want to interfere but you could try

No, that's all the files. Did you see my edit about the movable.sed? Also don't do a forced transfer yet.

 

[eworm]

Oh, movable.sed also passes no problem. It's the only file in the private\ folder, is that correct?

Yes.

Alright, there's a few more that need fixing that are system save files which are not as easily accessible by GodMode9. One moment while I compile and check how to fix those ones. If they also pass without needing to be fixed then it's the ID0 folder name that needs to change, which D9 usually calculates but failed for some reason with yours. I'll need to research how else to find it since the folder is missing off your SD card (which was the easy way).

This is as good a time as any for me to thank you for your time and effort. I appreciate it a lot. Hopefully my example will help even more people in the future, not that I wish anybody to get such convoluted bricks.
