Haven't tried this yet myself, but I know a new tool called "Rogero Downgrader PUP" has been released that's supposed to downgrade any CFW to 3.55. Google it, hope it helps.
if your not running CFW dont even think about that file, if your running OFW you will need to downgrade (depending on model and numbers) by using a flasher which isnt easy to install, and if you have a super slim you are shit out of luck even trying to downgrade
i have a slim got it 3 days ago and running CFW can i downgrade still? Because the game i'm downloading says you can play it on firmware 3.55 or 4.21
also take note if its rogero 4.40cfw keep in mind its a frankenbuild... in other words its build on other devs work(patches) so unless the original dev fixes some problems rogero aint gonna fix them... im afraid you should get the 4.30 or 4.21 cfw.... and btw there is a 4.40 spoofer.... so only multiman should tell you what cfw version you are on.... and btw 4.40 by MLT works very nice and has klicense disabled... in other words YARRRRRRRRR!!! games/dlc/psn/minis/themes work w/o any need of rif/rap/reactpsn... so yeah... YYYAAAAARRRRR!!!!
