Sorry, i dont know what you're doing but the code i provided works, not beeing anything else that a pure php implementation of the tea-decrypt algorithm, exactly like the DecodeTEA(AVal *key, AVal *text) from rtmp.c.

Remember that before make de tea-decription you need to transform the r2-string to make it hex-number:

function transform_r2($r2)
	{
	$_local2 = "";
	$_local3 = 0;
	$chars = "ABCDEFGHIJKLMNOPQRSTUVWXYZABCDEFGHIJKLMabcdefghijklmnopqrstuvwxyzabcdefghijklm";
	
	while ($_local3 < strlen($r2)) 
	    {
	    $_local5 = $r2[$_local3];
	    if (strpos($chars,$_local5) or $_local5=="A")
		    {
		     $_local5 = $chars[strpos($chars,$_local5) + 13];
		    }
	    $_local2.= $_local5;
	    $_local3++;
	   }
	return $_local2;	
	}

I've just implemented the code in rtmp.c and now it's compiled and throwing the right response, but there is some pings i must resolve.

C code for transposition

		  int local8,local3,r2size;		  
	 	  char *chars = "ABCDEFGHIJKLMNOPQRSTUVWXYZABCDEFGHIJKLMabcdefghijklmnopqrstuvwxyzabcdefghijklm";	 	  
		  char *local6 = text;
		  r2size = strlen(local6);		  
		  char local2[r2size];	
		  
		  local3 = 0; 
		 
	 	 while (local3 < r2size) 
	 	    {		     
	 	    local8 = local6[local3];
		    							     				     
		    char *b = strchr (chars, local8);
		    int pos = pos ? b - chars : -1; 
		    		    		   		    		    
	 	    if (pos>-1) 
		      {local8=chars[pos + 13];}
		      
		    char local52[2];
		    memcpy( local52, &local8, 1 );
		    local2[local3]=local52[0];
						    
	 	    local3++;
	 	   } 
		    
		memcpy(text, local2, r2size);:cool:
