Some more progress made, new code:

   byte[] request = new byte[] {0x00};
   byte[] response = new byte[0];
   Log.i("Sending MR command");
   boolean result = mTwi.writeRead(0x27, false, request, request.length, 
response, response.length);
   Log.i("MR command result: " + result);         // result is true after 
power cycling
   Thread.sleep(100);
   request = new byte[] {0x01};
   response = new byte[4];
   Log.i("Sending DF command");
   result = mTwi.writeRead(0x27, false, request, request.length, response, 
response.length);
   Log.i("DF command result: " + result);          // result is false

I am struggling to understand what should the value of the second request 
be for Data Fetch.
