I have recently updated to 4.3.3, ever since the update, my phone has been locked. I've tried using programs such as redsnow, umbrella etc to unlock. But I can't enter DFU MODE, Also I cant turn off my phone, Sleep + home button does not work also. any help please?

You need to be able to get into DFU for programs like redsnow to work.

Is there a way to get into DFU mode with my current situation?. I can't reset or turn the phone off.

As long as your home and power buttons work you can always get into DFU.
