So I was told that Japanese PS4s are identical to USA ones, just a different box. I got one that was on firmware version 1.52, meaning I can run exploits on it. Yay! Only problem... it has the Japanese mannerisms (Y/M/D date style, 24-hour time, safety warnings in Japanese) and the O/X buttons are swapped from my USA console. Even though I picked English (United States) when setting it up. As a test, I swapped the hard drive and downloaded a 1.60 "full" PUP file. But it still kept the Japanese style. Since the updates are identical in all regions, I get this feeling it's impossible to switch. I've seen some tutorials talk about opening the PSN menu and trying to change regions there, but it's going to just force me to update if I try to connect it to the Internet. I'm planning to update it to 1.76 at some point, but is there a way I can basically switch it to a US firmware? Would using a US retail disc with an update help? Or was I misled a bit and it's not really identical?
