how to fix a clicking bricked lego mindstorms nxt
I happens to have a LEGO Mindstorms NXT.
I just love it!
I have been doing/playing with LEGO all my life.
Today my youngest wanted to build robots with me.
He is 3½ years old, so we build parts of it together but I do the programming.
Soon he will learn or at least so I hope.
But when updating the firmware from version 1.03 to 1.05, things went bad.
Somehow the flashing process failed and I ended up with a bricked “brick”.
At the time I didn’t see how funny this actually was. But I was lucky to find a way to
fix this after a bit of googling. The process involves hitting a hidden reset switch.
The blog suggested that this switch is the one under one of the batteries.
That didn’t help anything, the NXT brick keeps saying “click click click”.
I actually assembled the NXT brick just to see if the switch was broken.
Which it wasn’t, and to be honest I really didn’t believe it my self.
But then i found another switch…
It turns out that the right switch to press with batteries inserted and no USB
attached is locate on the backside of the NXT brick in the upper left hole just
below the USB plug.
Holding it for 5 seconds did the trick.
The NXT brick now correctly boots into flashing mode.
Start up your Mindstorms NXT software and flash the (new) firmware
via the menu “Tools -> Update NXT firmware”.
If I just knew that from the very start…
Hope this helps you.
