Man, does anyone know how you keep your fucking wallpaper?
Like, whenever I change it, and turn the PSP into sleepmode or play a game, when I turn it on again, the background becomes pure black. Then you have to set up the wallpaper AGAIN.
Is there a way to make it permnant?
Hey guys, I just solved this, I will share what I did so if you have this problem, this is how you can solve it!
First of all, I assume everyone knows how to get in the recovery menu, so get there, and go to:
advanced-->Format flash1 and reset settings (it took all my courage to press this, but its harmless!)
Beware this will TOTALLY reset all your settings, (date/time/psp name)
Afterwards, boot into recovery mode once again
This time, connect your USB cable, and then go to
advanced-->toggle flash1
on your PC, your PSP will activate, you have but one thing to do here, make a new folder called "vsh" and inside that, make another folder called "theme", so it will be:
ms0:\vsh\theme
thats it. On your PSP, click "toggle flash1" again, and this will deactivate the USB connection, now just exit the recovery menu
FINISHED!
Now you can apply ".ptf" theme files AND wallpapers will no longer be reset,

This is EXACTLY how I did it (just 5 mins ago)
Hope this helps!
