(adsbygoogle = window.adsbygoogle || []).push({}); My issue: Just bought a 3.55 ps3 and jailbroke it. currently im on version Rebug 4.75.1 D-REX and when I covert to dex using Rebug ToolBox everything goes smooth and works fine and then Spoof to 4.76 I cant sign in to psn.
I have tried to fix my issue with: Research and asking around no one seems to help and know what the issue is.

What firmware should I be using???

Dex doesn't need a spoofer

I can convert to dex but I cant sign in.

what is the error code?

Look up how to sign in on a DEX psn. You have to use rebug toolbox

You don't need a spoofer on Dex buddy, I'm on 4.75 Rebug d-rex and can sign in no problems.

Before you sign in, go to Rebug Toolbox, then go to the last tab, and press Use PS3ID, then press Use EID85 (CEX) and then it will kick you back out to the XMB and you can sign in through there

Also i debug settings make sure your np environment is set to 'np'
