Nice tutorial this might be off topic but do u know there is a way to downgrade from 6.39 to 5.50 GEN with a psp 3k i just tried it and it works good lol

Sorry Juggs, but a psp 3k will never be able to run 5.50 GEN since PSP Brites (PSP 3000s) aren't fully hackable and they never will be unless some one can crack the pre-IPL on them. That and 5.50 GEN wasn't designed to run on a 3k.

That's why the perma patch was a big thing for 3k's and Go's, but it only works on 6.20

If you really want permanent CFW on a 3k you'll have to stick at 6.20, but if you want a GEN cfw and have a 3k (3g) model you can always downgrade to 5.03 and run 5.03 GEN-C enabler.

Not sure why you would want 5.50 GEN though? the newer CFWs are better.
