so putting a new HDD in your ps3 & upgrade to 3.41 will NOT work, as the NAND knows you were on 3.50 previously..
kk gotcha can u MAYBE send me a link where i can download the 3.41 fw?? cuz i might borrow my friends ps3 and he doesnt have psn so i dont think he has 3.50 and i think i found a psjailbreak for like 20-30 $$
