(adsbygoogle = window.adsbygoogle || []).push({}); So my nephew's PS3 was running CFW 4.76 CEX and he accidentally upgraded to 4.78 OFW. However the update fails at 75% when installing.

The PS3 still asking for firmware 4.76 or later. Not 4.78

I have tried to install 4.76 CFW again with another HDD of course since the old one just keep installing update.
But right after the PS3 preparing the update it says "The Update Data Corrupted"

So before i messed up with this PS3. I would like to ask is this still on CFW ? Does there something i can do to install CFW again without flasher ?

Any help would be highly appreciated.
