(adsbygoogle = window.adsbygoogle || []).push({}); Hey I was just wondering what happens when I use Format Utility on my ps3. I have been having problems on my 4.50 ita DEX and I just want to restart. BUT I don't want to LOSE my CFW.

You wont lose your cfw but all data on ps3 will be deleted.

Have you tried restore file system option from recovery?
