You have my sympathies, I know how hard that phase can be! I have 3yo and 18mo DSs who went through the same thing, and *man* was it tiring! And trying on my patience. I guess what I found works best for us is to give them options. Tell them what they *can* do, otherwise I felt I spent all day in a battle saying "No! you can't!" which clearly amped up their rage, too. So I'd try to distract with "Here, you can have this toy phone!" (instead of tv remote he wanted). I also read "Happiest Toddler on the Block" and I found that mimicking (not mocking, mind you) their frustration got their attention and helped them feel understood. I'd say "I know! You are SO ANGRY that you can't have that whatever! And you want it!" Then when he'd calm down and listen I'd say "Can Mama help you find something else to do? Can you help Mama make this puzzle instead?"
Didn't always work, but often it did... and sometimes even a slight reduction in the behaviour was a Godsend.
