    I have a slim psp with 6.20 PRO-B8 on it. The only time I have done anything with CFW is when I installed the 6.20 CFW. I have googled it but couldn't find a guide on how to do it.

    Any help that any can give would be greatly appreciated.

    Thank you.

    cause if you upgrade you lose the perma patch and have to go to a backdoor patch which is worse
