Features
Written in JAVA, so compatible with any OS that supports a JVM (Windows, Linux, Mac...)
Removed the need to use any external program (like SQLite Browser) and to find and edit SQL tables/records manually: all you need to do is to pass an app.db and your theme info, the program will write records automatically in your DB file at the correct table.
Support for SQL blobs: this means that you can insert even a title and an author/provider for your custom theme that will appear in PSVita Theme Settings page. In this way there will be really no difference between an official PSVita theme and your custom theme, like you can view from these screenshots HERE
Basic and easy to use GUI
Application's window resizable by the user so as to fit any screen resolutions
Tooltips with explanations on every field:
Support for drag & drop in the input app.db text field
The program will check if a record with the same UNIQUE key is already existing so as avoiding SQL errors.
Ability to insert all params about your theme info, such as version, last mod date, size, etc...
Ability to calculate the size of your theme automatically (by passing the main folder of your theme the program will calculate automatically the full size)
Ability to set the last modified date to now automatically
Ability to create a backup of your app.db automatically before writing changes
Ability to quickly fill all text fields with default values (I used the same of the HackInformer's tutorial)
English and Italian translations

I decided to share the 3.50 vita modules and prxtool mod with you guys, so everybody can take a look at it!

This dump contains more modules than you could have dumped with vitasploit (it even contains the webkit module or an other interesting module SceCompatDialogPlugin) The important thing is that all these modules are NID UNPOISENED which means that prxtool will be able to resolve all the known NIDS.

I have also included my extended db.json file in this package. This file has been manually adjusted, so don't mind the order of the NIDS. This database has got some SceAppMgrUser API's resolved which are very cool for you guys:
sceAppMgrPspSaveDataRootMount, sceAppMgrConvertVs0UserDrivePath or sceAppMgrLaunchAppByUri.

This is how to translate the modules into ARM assembly files:
prxtool -r 0x81EFC470 -i -b -w -n db.json SceVideoExport_0x81EFC470_0.bin > videoexport.S

The -i indicates whether the module is thumb mode or ARM mode. Most of the prxtool's feature won't work so don't bother trying other arguments than these here.
Have fun reversing guys!

What’s new with PSVita DB Theme Installer 360?

Instead of manual copy of the app.db file to and from the Vita, PSVita DB Theme Installer 360 has an integrated FTP client that lets it retrieve and update the app.db file directly to your device, meaning much less manual manipulations.

I have updated my PSProxy application to v3.1.0.0 which fixes some bugs regarding support to PS Vita.

This will allow you to bypass the new 3.61 update and sign-in to PSN on 3.60 firmware.

Instructions:
Press start on the utility.
Add IP and Port to the Vita.
Sign-In to PSN
Profit?

The client is currently available for linux x64 (ubuntu) and windows x64 (wip).

you should then add the flag back when releasing your application.

- Please note that when using psp2shell library, you're application
will never enter "deep sleep" ("power lock"), so the network connexion will not be lost.

- init psp2shell in your app : psp2shell_init(3333, 0)

- to print to the shell from your app use : psp2shell_print(..) / psp2shell_print_color(..)

- update/reload your app from the shell : reload "path/to/eboot.bin"

- type help (or ?) for more commands
cd, ls, pwd, rm, rmdir, mv, put, reset, reload, launch, umount, thlist, modlist)
