Add two wires to DFU and 3.3V (break out the DFU-Button so you can boot into DFU-mode while the case is closed). -<img src="images/b1.jpg" width="100"> -<img src="images/b2.jpg" width="100"> +<p align="center"> +<img src="images/b1.jpg" width="300"> +<img src="images/b2.jpg" width="300"> +</p> #### 2 - Prepare the IBM Dials Open up the case and unscrew the old connector.
