How to install .pkg Vita game update?

This seems like an easy way to decrypt a game:

Let me see if I can use to decrypt.

Wait a minute, I don't think this decrypt .pkg updates. Or am I wrong?

 

Yeah, I did decrypt it without ZRIF with pkg2zip, same error. I'm now trying this other method to decrypt .pkg how do I do it NPS?

Also, my Indonesian internet is fucked up, I can stream YouTube 1080P with no buffering, but downloading 42MB file off PSN takes an entire day.

 

Finally successfully patched Oddworld via NPS!!! 42MB patch file (3+ hour downloading time), Killzone is still downloading (42MB/536MB in 3 hours), but I've also downloaded an encrypted .pkg patch file off PSN, but I have no way of decrypting it.

I tried this method, but it doesn't seem to work:

How should I decrypt this? I did:
- unpacked via pkg2zip with ZRIF ---> error
- unpacked via pkg2zip without ZRIF , and then copied the work.bin from NoNpDRM game folder, and then decrypted the patch folder with _decrypt.exe ---> No result, there should be a new folder created, but none.

 

DONE!!! Successfully decrypted the .pkg patch with pkg2zip, game is updated. My problem last time was I was trying to patch the game with a single 1.11 patch, apparently this patch will not work unless I installed 1.01 - 1.10 patches in succession first.

I wanted to do this because update 1.11 removes the touch screen controls and replaced it with analog gestures for Vita TV. I was trying to force this mode to appear on PS Vita, because the option does not appear unless you play the game on Vita TV. Someone suggested that if I install 1.11 only and not the 1.12, the option might appear.

So installing 1.11 patch only doesn't work, and downloading patch 1.01 to 1.10 is too much work (1.01 alone is 1GB) , I'll stick with this 1.12 update (which is a 500+MB cumulative update).

Thanks for everything, I learnt a lot! Now I can download .pkg updates much faster and decrypt it myself.

 

New problem. The DLC downloaded from NPS are not recognized, and when I try downloading and installing the DLCs from PKGj, the game is corrupted and can't launch!

EDIT: weird, deleted everything. copied the game, patch and DLCs again with VitaShell and refreshed Live Area, now everything works.

Now, I backed up my saves (from my official cartridge game save), with this method: https://psvitasaves.xyz/faq.php#backup
Let me see if I can restore it.

 

BTW the reddit post is correct, patching a version 1.00 game doesn't remove the update button on the live area, the game is patched and on the info it is listed as the latest version 1.12 but the yellow arrow update button is still there. I deleted everything, copied the game and the patch at the same time, and then refreshed live area and only then is everything displayed correctly.

Also, the save backup restore doesn't work... it corrupted the game. Oh well, back to copying the game and everything via VitaShell again.

 

Nope, patch folder went into ux0/patch/PCSA00107 folder, save data I copied by following this instructions: https://psvitasaves.xyz/faq.php#restore

But I missed one crucial step, this: "In Vitashell go inside that folder and if you see "sealedkey", "keystone" or "clearsign" delete those files. These could be in a sce_sys folder."

I did it again, deleted said files and it worked, my save data is restored.

 

Thanks to everybody for offering their guidance, I made a lot of errors. At one point I disconnected my VitaShell USB connection during copying and it screwed up my NoNpDRM script. Searched online and found that I need to delete the tai folder in ux0 (whch has my NoNpDRM and my 0syscall6, and to reinstall Henkaku. Now my 0syscall6 is gone and my NoNpDRM is in my ur0 tai folder instead, but evrything works? Do I need to reinstall 0syscall6 too?

 

Okay, I'm running Enso 3.68, if I ever encounter any game that requires 3.68+ then I'll reinstall.
