can 3.60 be upgraded to the new cfw out ???

Can 3.60 be upgraded to the new CFW out ? i have been searching for a straight anwser and I have not found one . I am on 3.60 and want to install the new cfw firmware out . Can I upgrade to the CFW at all??? I have attempted to install Rogero 4.21 and get data corrupt on the install. Can I update to OFW then install the cfw like in 3.55. All I have been reading is that every one has to be on 3.55 to upgrade to the other CFW out their. Some one shout out some options that do not require soldering. I have a old PS3 backwards compatible 60 gig cecha. Any information will provide useful to me.


Thank for your time and efforts a local nobb.
