With the recent release of 4.60 official firmware, bitsbubba has made a version spoofer that works on 4.55 Zero and 4.55 Rogero CEX custom firmwares. It also works on Rogero 4.55 firmware with the NOBD patch installed. For those that need to connect to the PSN, this is one way that CEX users can accomplish the task. Just be sure to use a stealth app like psnpatch too! Get more information from the developer below!

version spoofer for Rogero/Zero 4.55 CFW :)

NOTE: Use with caution, I have no way to test, but should work fine!
