First you need to actualize your FW or the Hack don't work and for that:
1. Go to "Settings" then to the first option "System Update" (If you have hacked your PSP please take of the hack and then do this)
2. Clic "X" then "Update via Internet"
3. Select the Connection of your house
3. Then wait that confirm that there is a new FW
4. Select "Download"
5. Then when it's finished just select "Actualize Now" (FOR THIS YOU NEED TO HAVE AT LEAST 80% OF THE BATTERY CHARGED)
6. When the actualization finish then use the Hack 6.60 PRO-B10 (It's the most recent) Here Direct Link --> http://procfw.googlecode.com/files/660PRO-B10.fix1.rar
7. When you download the file unrar it
8. Put the files that are in the folder "GAME" onto your PSP "GAME" folder....
9. BUT JUST put the files "PROUPDATE" and "Fast Recovery"
10. then run "PROUPDATE" and that's all YOU HAVE THE PSP HACKED
11. I recommend you to run "Fast Recovery" too.... this help for recover faster the Hack (Example: If you PSP shut off fully, don't in suspend mode!! the hack desapear so for that's it's "Fast Recovery")
--> ONLY FOR PSP 1000 and 2000 WITHOUT PLATE(?) Ta-88 V3 and the newest (PSP 3000/GO)
If you want to do it permanently just put the "Cipl" folder to the "GAME" folder and run it
AND FINALLY YOU HAVE THE PSP HACKED!!
PD: I hope this help
