No, there isn't. But why don't you want to update from 4.11 to 4.21? If you were on 3.55 I could understand that, but 4.11?

Xbox 360: Slim untouched with a faked 320 GB harddrive for XBL, phat with LT 3.0, played Halo early, so going on live would be an instand ban, also with a faked 320 GB harddrive
PS3: Untouched 160 GB Slim, 60 GB Fat with latest Rogero and 160 GB internal harddrive.
PSVita: hardly ever play it
GameCube: Black with a Viper chip installed. With gameboy player. Trying to get a Wavebird controller.

Eisherz is right but only if you wish on using psn (playstation network) if you're not than just turn off your auto update in setting then you cant be updated unless you want to

heh... unless you know how to crack ECDSA

y^2 = (x^3 + a * x + b) mod p

this is the equation

the PS3 uses 160bit ECDSA algorithm so any vital key is encrypted by it
normal 160bit is 49 digits long.... now that's not enough.... you also have to find the random number used in the encryption and that number can be anything(any length) and that impossible by itself....

example of 160bit keys using the equation

and there are just simple numbers my friend lol the basic idea is this R = k*P EVEN IF you work out the R and the P "k" will never be found and the "K" is important here lol

ECDSA is here to stay it cannot be broken even simple DSA cant be defeated :3

i sugest you to read http://en.wikipedia.org/wiki/Elliptic_Curve_DSA to learn more on the subject it will make your head hurt for sure ^__^
