Hi i bought a psp go from a random person on the internet with 6.60 and cfw 6.60 PRO-B Fast Recovery However i wanna make this permanent and i understand that 6.60 permanent can be buggy so i wanna downgrade to 6.20 and install 6.20 cfw on it But i dont know if i should because i dont know if it came out the box as 6.60 or 6.20 I love this thing and i dont wanna screw it up but isnt permanent cfw better? then to use a quick install each time? It says Model 05g under mac adress and it is a PSP go N1004 PSPIdent wont work on it (i thought that might give me some answers) Do you guys know if i can install permanent cfw on this psp go? And does non-permanent cfw damage the psp? Thank you!
