um i could possibly help you out, first off i dont know if you want the newest firmware yet, cuz i heard it becomes a problem with a lot of people ,like some emulators wont work etc...but the way i can help you is, i can share the 4.01 m33-2 cfw file with you, it runs pretty much everything, ill even share all the stuff i have so far

You need to update to 4.01 then you can go to 5.00m33-6, this is the latest M33 software and has no issues, if you want to go to the PSN then you will need 5.50Gen-B, however this does have some issues, 5.00M33 runs most games (currently 6 games need 5.55 which is not available)
