If you are not yet on 6.39...
Download 6.39 official firmware (for PSP 100X/200X/300X) or (for PSP Go).
Place the UPDATE folder into /PSP/GAME/ on your memory stick (or the Go's internal storage).
Run the 6.39 update on your PSP and allow it to install.
Now to install the hack!
Download 6.39 PRO-B7
Copy the 639PROUpdate and 639FastRecovery folders to /PSP/GAME/ on your memory stick (or Go's internal storage).
Run 6.39 PRO-B Updater on your PSP, and press X to install.
Your PSP should restart into hacked mode. This will last until your PSP is shut fully off (sleep mode is okay). To hack it again quickly, run the Fast Recovery to get back into 6.39 PRO.
When you're done, you can delete the update off of your memory stick, since the hack is stored on the PSP itself and you only need to keep the fast recovery to re-activate it when needed.
