[Jouji]

is there a guide that can downgrade the psp version 3.30?

Update to 3.50 sony firmware!

Download this

Make a new folder on you memory card named UPDATE and place it in PSP/GAME

Then get your downloaded file and rename it EBOOT.PBP (if it isnt already) and place it in PSP/GAME/UPDATE

Plug in the charger and make sure your battery level is above 75% and run the update off the memory card under game!

Dont unplug anything and dont turn the PSP off while it is updating!

Then when you have 3.50 you need to buy Lumines the game (you can get this game off ebay or amazon for very cheap!), once you have Lumines the game email me or make a new thread here!

If you know anyone with a downgraded PSP you can use pandora battery!
