I was on Dex 4.81.2 rebug and wanted to upgrade my hard drive space so I bought a new hard drive and installed it.
Now it's asking me to press START and SELECT. When I press it, it says "No appliable update data found".

I have Rebug 4.81.2 D-Rex in my flashdrive. USB > PS3 > UPDATE > PS3UPDAT.PUP

Can someone please tell me what I'm doing wrong?
