Hi, I can't download from here.
I do this in three stages, and it works for me, it probably can be done in less steps, but hey.
you must down load this from mega upload DOWNLOAD, i t contains three folders and they correspond to the three steps below.
the download is no longer there.
the pandora is incase of a brick to enable recovery,when the keys were cracked for the psp it made signing of basically anything you want to be allowed run on the psp,with limitations only to your particular model,my sons is on 620 pro b permanent,im still on 5.33 cfw,there is some models that cant be permanent but the fast recovery is just a extra step,there is no need for the mms marker with the new cfw
5.33, that's the promethus CFW isn't it? This is what I am running at the moment also, I have found it runs everything that I have thrown at it so far. is there anything better with your son's than yours?
Windows would not be able to open that jimian it is a psp file,if you have already formatted the memory stick with the psp you will put that file in a folder called UPDATE all caps,then connect the psp to the computer and examine its file structure,you are looking for PSP open that and look for GAME it is in this folder you will put the UPDATE folder you made,disconnect the psp from the computer and turn on your psp and goto your game icon and update,make sure your psp is fully charged
