Hey FreePlay, you said that the psp's tested were all originally 1.50 to 2.50, what if mine was originally 1.0 and upgraded to 2.50, should it still be the same result as the others?

edit: Does anyone know what those 2 bricks original firmwares were? I'd want to try to do the downgrade with mine, but just want to be a little cautious first since there were some bricks with this.
