I have a PSP 3001 and I saw both 6.2 TN and 6.2 Pro. I heard that 6.2 TN is mostly for homebrew compatibility and 6.2 Pro is mostly for ISO compatibility. So I'm just wondering, how can I switch from 6.2 TN to 6.2 Pro and vice versa? And I think 6.2 Pro B8 is a perma cfw so thats why I'm just wondering.
