I left my ps3 in a store to make donwgrade. The man in the shop told me the ps3 is with the latest version of Rogero. But the error is in multiMAN, I start to multiMAN it gives me an error: "multiMAN can not enable bd-rom emulator. Functionality may be restricted, error: unsupported system firmware. Blacked out and went to install Ja, ja installed and eliminated many BDEMU times and nothing.
Does anyone know how to solve?
