How can I do it?

Please don't start with the old "Why would you want to? M33 is better", I just want an answer to my question.

I think if you have the 1.50 file on your memory stick in the recovery folder then you can run a program from your recovery window that will make your psp revert back to 1.50.
"run program at / psp/game/recovery/eboot.pbp"

If I'm wrong about the above then you need a Pandora battery to and original magic memory stick in order to downgrade to 1.50

Then from 1.50 you can install 3.40 oe-a

Yeah scratch that 1st suggestion. I tried it and it didn't do what I thought it would. Just use Pandora.
