why would you wanna go back?

to use 4.21dex PS3UPDAT.PUP

nope you cant unless you have to to downgrade with like a e3flasher or progskeet. You could of bypassed the update though but i doubt that sony updated there keys much because there was not nothing major added into 4.25

does anyone know if there could be a 4.25dex

wtf lol 4.25 is DEX

only progskeet or e3flasher
