(adsbygoogle = window.adsbygoogle || []).push({}); ok so my ps3 is on the 4.11 ofw can i just upgrade it to the rebug 4.21 firmware or what will i need to all do i would like an answer quick thanks

Only people currently using cfw can use 3.56+ cfw. You would need to downgrade your ps3 to 3.55 first and then you could use a 4.21 cfw.

so i can never jail break my ps3 again without a e3 flasher?
