How to recover NXT from clicking brick syndrome

How to recover NXT from clicking brick syndrome

20382

The brick is dead, and it's making clicking noise!

Generally this happens when the USB driver is incompatible with NXT Brick.

 

Two USB Drivers

The NXT Brick uses two USB interfaces (thereby needing two drivers). First driver is needed for normal operation (when you are connecting the brick to your PC while making your robots). Where as the second driver is needed when the brick is in firmware update mode.

 

The first driver is generally installed when you install the NXT software, where as the second driver is a default driver provided by the operating system. In Windows 7 (or higher) the default driver is not compatible with the NXT brick.

When you invoke that driver to upgrade your firmware, the firmware upgrade fails and brick goes into a clicking mode.

 

Device Driver in Firmware Update Mode

Connect your clicking brick to your computer using a USB cable and open the 'Device Manager' of your computer.

(Right click on 'My Computer' and select menu 'Manage')

Look for LEGO Devices, and see what the brick is listed as.

If you don't see 'LEGO Devices' at all or it isn't listed as 'LEGO MINDSTORMS NXT Firmware Update Mode' then you have incorrect driver.

Workaround - Use Windows XP or Mac for your firmware update

insert screw-driver to hard reset

 

Hard reset your brick and then update firmware using a Windows XP or Mac computer.

 

(For hard resetting, there is a press button in top corner mounting well on the bottom of the brick - press and hold it down for about 5 seconds).

Hi, I tried many things said on forum and the only working solution was here : http://www.legoengineering.com/clicking-brick-syndrome/By Gianni : 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.
