all psp version is downgradeable now?? anyone know??
no, depends on the mother board.
open your UMD slot, and check for a white sticker, if no have then can down grade.
icic...non downgradeable psp cheaper rite??
if i am not wrong the new 3.50 downgrader works on all motherboards
use flashed firmware instead.....now only versions 2.7 and below can upgrade with the flashed firmware
