No if your on firmware 3.56+ you need a e3 flasher or something similair to downgrade (if your ps3 is compatible)

Moved to PS3 Mod Questions. You cannot downgrade a 3.56+ OFW through USB, and if you are attempted to hardware downgrade, please make sure your PS3 is compatible

If your PS3 is not compatible, try looking into using Cobra ODE, which will allow for homebrew, emulation, among other things.


Edit: Closing this thread, as you've been spamming the PS3 forums all day long, and NextGenUpdate does not accept your behavior.
