Hi, I just wanted to say that I have checked many threads on the forum. Though, I apologize if i sound redundant. I have already checked the sticky regarding the the custom firmwares questions but I have found that the last edit is from a long time ago. I would like to know if its possible to downgrade from 3.66 to 3.55 (without soldering), or update 3.66 to a recent version to be able to use a recent CFW. I could not find any recent CFW, so I am curious, are there any? Are there any work on custom firmwares for 3.66+. Also, for 3.55 systems, is it possible to play the games that require 3.6+? Again, I am sorry if I sounded redundant. Thanks for your time.
