How to download from the psn store using psp 3000 GEN-A

NOTE: if you are using psp 1000 or 2000 this will work but I would suggest upgrading to 5.50 gen
NOTE 2:this is the name of your psp for example mine would be vsh:p6427 go into system configuration -> system information its the first one

Editing version.txt for media go to work

 

press select to access the vsh menu press the down arrow to recovery menu go down to
Run program at /PSP/GAME/RECOVERY/EBOOT.PBP and go to toggle Flash 0 (usb mode) press x connect your psp to your computer (if you haven't already). Once in your memory stick, go to the VSH folder, then to the etc folder. In here will be a version.txt. First we will need to make sure its not read-only, right-click on the file and go to Properties and uncheck the Read-Only attribute and hit OK. Now open the version.txt file.

release:5.51:
build:3218,0,3,1,0:builder@vsh-build6
system:52303@release_551,0x05050110:
vsh:[*read note 2]@release_551,v52628@release_551,20090605:
target:1:WorldWide

 

Using Media Go
