(adsbygoogle = window.adsbygoogle || []).push({}); Hi there so i want to downgrade my ps3 using 999 downgrader from rebug but when i go to system update it is grayed out and what does this mean and is it safe to go throught recovery/safe mode and update it there or should i just install 4.70.1 d rex straight from 4.75.1 d rex

u gotta use the special 3.55 dex downgrader pup file..regular 999 downgrader wont work as u r on dex !

Thank will i have to install via safe menu or normal way

either works..first try the regular way via xmb..if it fails or gives an error..try the safe method !

Ok thanks m8
