(adsbygoogle = window.adsbygoogle || []).push({}); I just converted my ps3 from CEX to DEX while on cfw rogero 3.55 now whenever I plug in the USB with an update etc it says storage device cannot be found or it finds it and loads and it says file corrupted I already tried +25 different PUP files. It says "Rogero 3.55 Downgrader" when I start it up idk if that really means anything. I tried changing Firmware everything.
Help would really be appreciated.

Did you put it in the RIGHT slot of your USB inputs?

The far right? The closest to the Blue Ray? In that case, Yes.

You need A DEX Downgrader
Use the PS3 ITA DEX Downgrade if your on DEX

Edit: Also try recovery menu.

Turns out I'm on CEX firmware.
I still can't install any firmware it keeps saying no matter what PUP file I put in the USB.
Can we Skype? I really need help.
