Clicking brick syndrome

Have you got this situation?

Your LEGO NXT Brick wont start… it wont show up… but it gives a strange sound.

Put your ear right up to the LEGO MINDSTORMS NXT Brick with fresh batteries and it turned on. Do you hear a clicking noise?

tic… tic… tic… tic… tic… tic… tic… tic… tic… tic… tic… tic…

There is no way you can start your brick. Whether you press the orange button or whatsoever. The brick isn’t even recognized in the NXT software! But don’t worry, this is a very common problem. Let’s see…

There are many names for this case:

  1. Dead brick
  2. Clicking brick syndrome
  3. Coma state
  4. Samba mode   (technical term!)
  5. You can also give a creative name!

Explanation: Very simply, the firmware got washed-off / corrupted / erased / anything else! That’s it. There is no physical damage to the brick.

Reasons for this problem:

  1. Unfinished Firmware update
  2. Hard Reset (Button) applied
  3. Changing firmware / installing different firmware (changing the firmwares  like NXT, RobotC, Enchanting, Labview etc.)
  4. Seriously bad programming (rare, but not impossible!)
  5. Pulling out the USB Cord while a program is downloading
  6. Anything else… ______________

 

Solution: It’s very simple to solve this problem.

1.  First try the Hard Reset as shown below.

2.  Connect your NXT Brick to the computer.

3.  Open your LEGO MINDSTORMS NXT Software, go to Tools -> Update NXT Firmware

4.  Check for the latest Firmware version available

5.  Select the latest Firmware Version and Click on the Download as shown under. Let it finish its work.

6.  Your NXT Brick is now ready to use!

7.   Precaution: Do not update the firmware when batteries are flat or low on charge. You may totally ruin your NXT brick!

Happy Roboting…

  1. I have several bricks that went into clicking syndrome with a firmware update, I have tried all suggestions here and it isn’t fixing the problem. I have unistalled the driver as suggested, tried a hard reset but when I go to download the firmware again it says currently no bricks connected via USB. It isn’t recognizing the brick while it’s in clicking mode. What do I do?

    1. I had the same problem and none of the suggestions have worked for me so I came up with my own way combining some of the other suggestions. So first disconnect from the internet then open up device manager by going to my computer right click and select manage. Then connect your NXT to the computer and you will see the device manager refreshes. Go to ports and select the Bossman port and click on update driver, click manual update and then select “select own program” then there will be a list of drivers and select the lego driver. Then you can go to the nxt software and update the firmware to get it working again.

      1. I had the exact same problem. I was able to fix 5 of 6 bricks using both suggestions above. However, the last one will not work with either your steps or the ones at the top of the page. Any additional suggestions?
