someone told me that i can update the cracked firmware to 300d to "open" the hidden functions which are similar to 10d, is it true? if yes, can anyone show me the steps or where can i learn more of it? pls advise, many thanks!

我部300D剛過了保用，我都好想知點可以裝。
唔知我想要的單張對焦，同閃燈曝光補償，佢俾唔俾到我呢？
另外唔知可唔可以裝回原本的firmware。
謝謝。
