How to downgrade a 3.11 psp?

Is there another way to downgrade from 3.11 some way without having to rent lumines?

This is in the wrong section, should be in help

Anyways...

Yes... purchase a mod chip then solder it to your motherboard, or... Send it to the guy on ebay that fixes completely bricked psp's lolol Don't be cheap, go out n spend the $5 to rent the game or purchase it for $15.

Its a friend that wants cfw ive got $30 so if i wanted to i would! ok ill tell him to get Lumines before even thinking about it.

He doesnt have a TA-082 if it helps

You didnt really read up on the downgrader did you?

It works on all psp's with all motherboards as long as the firmware is 3.50 or lower.
