if you are on CFW you have to install the 3.55 OFW first before updating to a newer OFW .
it either brick you system or lead to bann when they discover.
but now worries til the end of Feb. March. Sony wont release a new update :p
they are way to busy on the GeoHot/Fail0verflow Lawsuit and how they are going to solve the Leaked Root Key Problem :rolleyes:
so sit back and relax
