I have 6.20 PRO-B8. It was suggested previously that I update to 6.60 on this page:http://wololo.net/wagic/installing-pro- ... 2000-slim/
However, here's where I get lost:
"To install the 6.60 Firmware, just unzip the archive on your PSP’s memory stick, in the “PSP” folder (you should end up with an “UPDATE” folder in the PSP folder, if you do things correctly), then run the update from your PSP menu."
I have no idea how to "run the update from your PSP menu", and apparently my inability to understand this step is preventing PRO Update from running correctly.
