(adsbygoogle = window.adsbygoogle || []).push({}); So i have a ps3 slim and a
FAT PS3 on a very old firmware but it has YLOD,
if i give it for sony to fix would they put it to the newest firmware,

Q2,
Isnt it that you have to be on the newest firmware to sign in,
So how would you sign in if you are not on the highest firmware?

No it will stay the same. i sent mine in & when i got it back it was still the same firmware.

i honestly i have no idea sry.
