dumping your games or apps without pfs protection

[ShrineFox]

I kept getting an error trying to transfer the psp game with the pboot back to my Vita.
It's this exact thing:

what's the error?

During copy PSP Game from PC to Vita, after transfering it from PSVita (so it shows ~1,1GB instead of 230MB) - C1-2753-7 error
Before doing this i've deleted all folders in pspemu dir (except GAME and flash).
No matter which method i use (abb.db, pboot.pbp) - the same error.
After this error, when i check pspemu (ms0:) directory i have:

-temp (empty)
-PSP (Game, license, savedata dirs)
-flash (TNV files)
-SceIoTrash (empty)
-data (empty)
-music (empty)
-mms (music, photo, video dirs with AVContent.db in it)
-calendar (calendar.db file)
-id.dat

(From this thread: viewtopic.php?p=402455#p402455)

Solved by using the database dumping method, but instead of ../../../. I put ../../../app

However, I still get an error (albeit a different one). It's c0-11274-5 error, "failed to copy some content"
so idk if the dump is incomplete or if it's just the psp game that didn't dump. Is there some sort of filesize cap?
The PSP game itself is already ~ 1 GB and I don't see the size go over even 2 GB in the content manager, even when I'm dumping a 3 GB game.

Maybe I should try with a smaller PSP game?

Thanks for the tutorial.

After a lot of trial and errors, I managed to decrypt a PS Vita retail game cartridge successfully.

1. Backup the cartridge.
2. Install the backup files.
3. Manipulate app.db using the method in this thread.
4. Keep the cartridge inserted while decrypting the files.
5. Profit.

The sequence of operations is very very very important. DO NOT touch app.db before the backup is installed successfully.

No, it is impossible to decrypt the files without installing them legitimately.

The files that needs decryption must be fully licensed (that you can actually run). If not, launching Near (Manual) via Browser will instantly result in an error. Therefore, it is absolutely necessary to keep the cartridge inserted while decrypting.

However, I guess that decrypting a digitally bought game from PSN store seems to be very easy, since it naturally meets the conditions (fully installed and licensed). Just edit the app.db file and you are good to go.

Love you

I really dreamed long of decrypting retail games. Originally I thought only after PS4 has been fully studied can people find something about PS Vita, then decrypt the contents...

By the way, it costs me a little bit more than $10 USD to decrypt the game since it is required that the backup files be installed legitimately. Nowadays you cannot trigger an update download via PSM in older firmwares (I'm on 3.18), it does nothing but forces you to update. So I went to GameStop and bought a used copy of LittleBigPlanet solely for triggering an update download.

@ShrineFox
try to specify the game id
../../../app/your_game_id

Good idea, next time I run into that I'll try it.

I actually solved the problem by rebuilding the database and starting from scratch again.
For some reason that helped

Hey, could you tell me what sort of files/folders you saw within the decrypted game? Like, were there file types we've seen before (eboot files, PARAM.SFO files, etc), or was everything completely unknown? I tried carrying out this tutorial but I couldn't get past the penultimate step.

I succeeded decrypting Destiny of Spirits game and now I wish I could extract the graphics from cards stored in a .gxt format just to play with them. I know there is a library in vitasdk that deals with that kind of files, so any help would be very apreciated in order to get images maybe in png format out of .gxt files through rejuvenate...

Please refer to this thread viewtopic.php?f=65&t=45014 to find out the files and folders in the cartridge.

That tells the system to copy the file "app" 3 directories above the current one.
Tried ../../../app/. Dumped correctly (along with other encrypted apps)
The game I dumped was Gravity Rush. The data is in a huge psarc file. Any way to extract it?
