=>JL: burnchipkey 0x152f
Your current chip key:
    _     ______    _     ______
   /|    |_____    /|    |_____
    |          |    |    |
  __|__  ______|  __|__  |

Chip key you're going to burn:
    _     ______  _____   ______
   /|    |_____  |     | |_____
    |          |  _____| |
  __|__  ______| |______ |

Well, there is a key burnt into this chip which won't let this key being burnt correctly.
Here's what you get instead:
    _     ______  _____   ______
   /|    |_____  |   / | |_____
    |          | |  /  | |
  __|__  ______| |_/___| |


Do you still want to proceed?
Say "yes i do" to proceed: yes i do
Result:
  _____   _____   _____   _____
 |   / | |   / | |   / | |   / |
 |  /  | |  /  | |  /  | |  /  |
