Recently when I plugged my NXT brick into my PC I clicked on the wrong option and now all it does is clicks when I turn it on? How do I get it back to a usable state?

Hold on... are you seeding this site? (Seeding == asking 'not genuine' questions.) –  muntoo Nov 14 '11 at 23:04
    
@muntoo: Yes, the Mindstorms proposal has been closed, and we're adopting their questions. Essentially, what they'd do during closed beta if it had happened. –  user23 Nov 14 '11 at 23:22
    
@JoeWreschnig I thought that was discouraged. (Or maybe my knowledge is outdated?) –  muntoo Nov 14 '11 at 23:38

@muntoo: I've never seen seeding discouraged, as long as the seeded questions were good questions - they should originate with real issues real people (ideally expert people) have. This is the same process used for Area 51 questions. Hopefully, the Mindstorms proposal did that. Normally, this all happens during closed beta. blog.stackoverflow.com/2010/07/… –  user23 Nov 14 '11 at 23:53

Some of these questions are worth asking, and this one certainly belongs. (Not sure I would have placed "samba" in the question though; to me it's more likely to go in the answer) –  Joubarc Nov 15 '11 at 5:12

If you are using NXT-G, the software that comes with the NXT set, then here is what you do:

  1. Get into NXT-G, start a new program.
  2. Select the tools option, and from the drop-down menu, select "Update NXT Firmware..."
  3. Plug your USB cable (one comes with the set) into your NXT. Don't try using bluetooth, as it won't work.
  4. Click the download button on the interface which popped up at the end of step 2.
  5. Don't unplug your NXT, wait until it reboots with its firmware loaded.

Congratulations! You have just brought your NXT out of SAMBA mode!
