1) Download the PBOOT_dump.PBP file if you haven't already and rename it to only PBOOT.PBP

2) The next step is to transfer the file to your Vita and apply it to any PSP Game.

There are different ways to do that:
Method 1: Use TN-V / ARK / VHBL in combination with VitaFTP for example
Method 2: E-Mail write Method (for 3.00 - 3.52 with smaller PBOOT)

1) On your Vita open the VitaFTP Homebrew App via VHBL, TN-V, ARK or whatever.

2) On your PC open FileZilla or any comparable ftp client software to transfer files and connect to the IP displayed on your Vita.

3) And transfer the PBOOT.PBP file into any PSP Game of your choice next to the EBOOT.PBP

ms0:/PSP/GAME/GameIDofYourChoice/PBOOT.PBP

4) If there happens to be a /temp/ folder, delete it!

1) Download this smaller version of the file and rename the 'PBOOT_dump_.PBP' file to '#0' without any file-ending!

2) Now we are going to write a new e-mail with the #0-file as attachment and the path we want the file to be installed (ux0:pspemu/PSP/GAME/GameIDofYourChoice/PBOOT.PBP) as Subject. Send it to your vita!

3) If everything did go right you should see a camera symbol. Touch it and DO NOT click OK on the appearing Error Message but simply close the e-mail app completely!

Optional: It might be a good idea to check via a PSP filer/FTP Homebrew if the process was successfull if you have access to it.

And since your connected to the Vita already check if there happens to be a /temp/ folder in the root, if yes, delete it just to be sure!

3) Now connect your Vita to the PC and transfer your game with the applied PBOOT to your PC. (The PBOOT will be recognized and applied to the game)

4) Transfer your backup back to your Vita. (The bubble will change its look)

5) Transfer the game once again to the PC (You will notice that it will take longer this time.. thats because your whole memory card gets backed up now)

6) Transfer this backup once again back to the Vita..

7) Now once again open VitaFTP and check the ms0:/temp/ folder..

To get all these files onto your PC at once I would suggest you to use a PSP and the Adhoc File Transfer v0.7 Homebrew by Minerva.

Note: If you want to redo the process, remember to delete or rename the /temp/ folder first!

All the magic is located in the PARAM.SFO of our PBOOT.PBP file

../ means move up a folder

By default if we do a game backup via CMA it backs up the 'NPUGXXXXX' folder and all its subfiles for example. If we now move up in the folder hierachy 4 times via this trick, we are at ux0: (the root)! This way everything gets backed up at step 5.

And because the Vita isn't prepared to find all these folder in the backup, everything simply gets transfered and stays in the temp folder. Simple as that! :D
