I have a PSP 2000 model it had cfw 6.60 on it.
Recently my memory card shows up corrupted so i had to format it.
Now what should i do, its just blank , should install CFW again?
Formatting the memory stick will not remove the CFW files from the PSPs flash0.
If the CFW you had installed was a LCFW then all you need to do to get the CFW back is put the launcher/fast recovery back on the memory stick and run it
