Currently I am using CFW 3.90 M33-3 CFW on my PSP 2000 with PSP Slim 2000 TA-085 V1. I am able to play some fixed games like WWE 2010, NBA 2010, Motocross Arctic, with Decrypter B2. Now my problem is that I am unable to upgrade from 3.90 M33 to CFW 5.00 Gen or Higher. I tried updating my PSP with CFW 5.00 but my previous hack with 3.90 M33 is also updated and I am unable to see ISO folder on my PSP. Can anyone help me out?? I really need to update from 3.90 M33 to 5.00 or higher version. Please let me know how I can do it.
List of Question:
What should be done to upgrade from CFW 3.90 M33-3 to 5.00 Gen or higher?
Do I need any OFW before updating CFW 5.00 GEN or higher?
Do I need Pandora stuff while I am upgrading?
Please help my giving step by step hack
Thanks for any of your help
