(adsbygoogle = window.adsbygoogle || []).push({}); Ight so I had this problem before and it well sorta broke my PS3 but anyways so last night I was wanting to update to 4.78.1 Rex and after I did everything n went to the update thingy it showed the update on my usb but it was grayed out n when I tried downloading it it would just restart my system I also tried it in recovery mode I'm on 4.75 DEX

Is your qa flagged enabled?

Well when I bought this system from someone they said it was already qa toggled but how would I check that

just install 4.78.1 D-rex

I'll post back letting u know if that works

if your 4.75 DEX, it will work

Go to rebug toolbox and it'll be at the last row at the right side! Qa flag should be at the first/second column! Check if it's enabled or disabled! If disabled , then you'll have to enable it in order for you to install any CFW!

I'll post back letting u know if that works

It says it's enabled

It should let you install any CFW since it's qa flagged!
