There's no reason for you to downgrade to 6.39! You can use PRO CFW or LME on 6.60 itself!

If it has Pre-Installed, there is no way you can downgrade (yet)

@popo
as what nisarg_kolhe said no need to downgrade install 6.60 PRO-B10 or LME 1.8 or even both

Thank you for your help!!!

Actually you can, the new chronoswitch downgrader by Davee made it possible for PSP 9g to downgrade as low as 6.20 and install the permanent patch!

That my friend is false. He can install every FW which provides 09g modules, it does not matter which FW was pre-installed.

There's been a downgrader for 6.60 since August 23, 2011 Where have you been?!?

As for downgrading a PSP 3000 9g, technically it can be downgraded to 6.20 (you can fake it to a 4g) but it's not worth the risk when you can simply use 6.60PRO-B10f1 or 6.60LME 1.8. (You can find both in PSP/Custom Firmwares (HEN/CFW/LCFW)

downgraders. but They all do not work and get error "CAAFFFFFCF7".

IMHO, it was never worth the risk in the first place. 6.60PRO/LME are very good (L)CFW's. If you need any help with plugins etc on them feel free to PM me or make a thread in one of the sub forums (depending on what it is you need help with).
