Hacking Update PS3 on CFW 4.55 Rogero to latest stable CFW?

[hankarlo]

Hi all,
I haven't updated my PS3 CFW in a couple of years. Is there any real benefits of updating to the latest ReBug? If so, how do I go about updating? do I need to downgrade or is it possible to update from the xmb?

Cheers and thanks for reading
