I need help downgrading

Hi, I'm new and all.
My friend Pazicles sent me to here, told me you guys can help me.
Well My psp runs on the firmware of 1.52.
I've been looking but I'm not sure..
Is there a way to downgrade my psp to 1.50?
I really want to play some good old games on my psp.
Thanks for the help.

Things you should download before u get started.

-MPH Downgrader (make sure theres no virus)
-2.0 EBOOT
-1.5 EBOOT

Search for it on google. But first upgrade to 2.0 and after you have upgraded downgrade to 1.5. But before you do anything, like even think about asking about how to do it correctly, I suggest using the readme file.

we have clean mph files on this website somewere thats were i got mine until i found out i had 2.01

If you still need help feel free to pm me Montes.

so did you get it downgraded successfully?
