Hi everyone! Today I’ll be guiding all of you in wololo.net trying to put some sweet on their PS Vita and PSTV. There were some guides about how to put some custom themes on your systems but they were kind of complex. That’s about to end with the tools provided in this tutorial and the hard work done by Red Squirrel.

Requirements:

-PSVita/PSTV DB Theme installer 1.1 Here
-A Custom Theme of your choice
-Thunderbird for Windows Here
-A PSVita/PSTV between 3.00 – 3.52 firmware
-A Windows running PC

1.- Getting the app.db File from your PSVita/PSTV.
For this you’ll need to do the Email trick on your PS system for getting the file (if you’ve done it before you can just keep this tutorial). If this is the first time doing the email trick you can check the forum on how to make the first step. You can use this tutorial to start up: Here
To get your app.db you have send an E-mail to your PS system with this text as an attached URL

email:send?attach=ur0:shell/db/app.db.

Here’s a screenshot using Gmail (sorry for the language but I’m Spanish native-speaker)

Open the Mail app on your PS System and hit it the link on the mail you just received and a window for e-mail writing should be opened, send the email to yourself and open it on your PC. It’s ok if the email app on your PS System closes after hitting send, that’s normal. The attached file in the mail it’s your personal app.db file!

2.- Writing on your app.db file.
In order to activate the themes on your PS system, your app.db must have the info of your custom theme in them. Open the app.db file with the DB Theme Installer and complete the fields.
It should look like this

3.- Transfer your Custom theme to your PS System.
You can use any method you want to transfer the folder with the custom theme, like the FTP file transfer method. Notice that the path you choose must be the one you put in the DB Theme Installer.

4.- Write back the app.db file on your PS System.
Using the Thunderbird send an e-mail to you with the subject:
ur0:shell/db/app.db
Attach the app.db file and rename it “#0” (without the quotes) and send it to your Vita.
Here’s the screenshot

Open the Mail app and search for the mail you just sent. Click on the attached file (should be displayed as a camera icon. If there’s a “?” symbol, repeat the last step and send again the mail). Close your Mail app (DON’T HIT THE OK BUTTON)

5.- Restart your PS System

Restart your PS System and go to Settings to change your theme.

6.-Enjoy! 😀

NOTE: rebuilding your Database will reset your app.db and you’ll have to do it all again.
Thanks to Red Squirrel for the tool used in this tutorial and mr. gas for the writemail method.
