Is it really possible ?
Even if the update flag is permanently set ?

Thanks for this app Proxima! :)

Anyway, the app made by cfwprophet need to lower the "unique" characters ;)
The one made from tomtomdu80 is working well, but if you want a better GUI, the cfwprophet version is very good: LINK.

Proxima, this tool can be used to find only update files or also the normal pkgs?
Thansk again!

This is only for how the vita downloads updates, not original pkg files.

Hey,

I am trying for nearly 5 hours now to get this dang hmac_sha256 function working but everything errors and I don't know what to do now.
Proxima's Link hasn't all Dependencies in the Repository and other Dependencies don't work.
Has somebody a working Source Code ? (maybe on Github)
I don't want a compiled Version because I am working on a bigger Project with NoNPDRM Dumps where I have to batch check for Updateds :D .....

Greetings Lucas

Here's a Python script I wrote few days ago: https://gist.github.com/mmozeiko/4f868c ... b5a80da952
Examples:

Code: Select all

$ python get_update_pkg.py patch PCSB00786
Name: STF Ultra
Patch: http://gs.ww.np.dl.playstation.net/ppkg/np/PCSB00786/PCSB00786_T1/de17f818a05071b2/EP2003-PCSB00786_00-SUPERTIMEFORCEUL-A0102-V0100-5bd071fb2ba4d4718223a2ac7d621d81986b0248-PE.pkg
Version: 1.02
FW: 3.52
Size: 69046176

$ python get_update_pkg.py patch PCSE00491
None

$ python get_update_pkg.py latest PCSE00491
Name: Minecraft: PlayStation®Vita Edition
Patch: http://gs.ww.np.dl.playstation.net/ppkg/np/PCSE00491/PCSE00491_T56/6e9f5f7ad0e40815/UP4433-PCSE00491_00-MINECRAFTVIT0000-A0157-V0100-bb616dca2eb6637d4c388aca98ce16adb587c120-PE.pkg
Version: 1.57
FW: 3.65
Size: 964788064
Basically "patch TITLEID" will return info about latest patch that works on 3.60 or "None" if patch doesn't exist or requires 3.61+. "latest TITLEID" will return info about latest patch, including one that potentially requires 3.61+ fw version.

Enhanced mmozeiko's Python script a little bit: https://gist.github.com/windsurfer1122/ ... df21d91a53

Enhancements:
  • When using the script in automated scripts then error messages on stdout can be harmful for further processing. Therefore implemented eprint() for error messages.
  • Some titles have new lines in their string. Therefore used replace() on name retrieval.
  • Added command "nps" to output TSV lines for NPS database including XML URL and SHA1.
  • Renamed "info" command to "xml" as it fits better and is easier to remember. Also fixed a crash in this routine when no update is available.
  • Allow to calculate hash with PSV key for any given value (currently SHA256, SHA1, MD5).
  • Display help whenever the parameters are not right.
Update 2018-03-26:
  • Added RIPEMD-160 for hashing

Btw does anyone know what the hashes in the update package URLs are?

Example URL:

  • 650e9d8042dd5a01 (64-bit/16 chars) = ?
  • d20e9a97cca6e1082b6e6c2073411ba8181a52ac (160-bit/40 chars) = ?

all you would need to do is set up a router to search for a specific https connection, and reroute it to another site, or better yet, your own home server with the files you need.
