Homebrew Help -cfw app and games gone

[saintcarmo]

Hi guys, I have a problem. I have a 2 sd cards saved, both with B9bs and luma, so one of them (which I was using) got corrupted. Ok, I got the second because it had games and other files, but they disappeared, even containing the splahs of the sd running and the sd showing no aspect of being corrupted. In summary, all the homebrew files are gone, even though I still manage to enter the luma is to the B9bs is the space of the applications is still in SD, could anyone help me?

1. Copy everything off the SD card onto a computer.
2. Reformat the card in FAT32 + 32 KB cluster size with Windows File Explorer or guiformat if bigger than 32 GB.
3. Full Write + Verify the empty card in H2testw. Do not skip this step.

Report back your hardware test results.

Before doing the above, simply go into the "Nintendo 3DS" folder, you will see a folder with many random characters as it's name. Open that folder and if you see only one folder of again many random characters as a name, then follow the above. If you see two however, compare the sizes, then delete the smaller one and rename the bigger one to exactly what the smaller folder was called (copy past the name). That just happens when changing SD cards and the system re-makes the ID1 (the folder name of that folder so if it doesn't match what the system is using titles don't show up). Just for reference, it's "Nintendo 3DS"→"[ID0]" (this never changes on each system)→"[ID1]" (this changes between SD cards).

I tried to do the way ThoD , I did not get any results.




I checked in h2test, the result is below.
Warning: Only 7578 of 7579 MByte tested.
Test finished without errors.
You can now delete the test files *.h2w or verify them again.
Writing speed: 6.98 MByte/s
Reading speed: 19.2 MByte/s
H2testw v1.4

So your SD card is good. Look in the Nintendo 3DS folder.

• sdmc:/Nintendo 3DS/<ID0>/<ID1>

You want only one 32-char <ID1> folder. If there are two, find the one that has your stuff.

Other than that, keep in mind that your <ID0> are not interchangeable between different 3DS systems (unless it's target system receiving the setup from System Transfer) and reusable on the same 3DS/2DS after Format System Memory because of encryption.

There are ways to correct for the latter case but that depends...

huuuum, I understood, the sd exchange occurs in the same system and the splash appears showing that it can still read the sd, so I do not consider that it should be a problem of 3ds.I will study further down this folder because in my so appears in the image attached and because of this I am confused as to follow the instructions correctly.

1. You have two <ID0> folders, one of which has your original setup.
2. You can't shared <ID0> folder between different 3DS systems because of different movable.sed.
   • Unless it's System Transfer.
3. You can also lose the matching encryption KeyY tied to that <ID0> on the original system if you did a Format System Memory.

To learn more about this, read here:

***

You might be able to brute force back the lost KeyY using this gm9 script.

• CTRTransfer (Type D9)
• Make a SysNAND backup before you try finding it.
  
• Do not use the actual CTRTransfer option. You want the run the KeyY option only.
