The 1.31 firmware for the brick is here -> http://www.lego.com/education/school/default.asp?locale=2057&pagename=softu&l2id=3_2&l3id=3_2_4&l4id=3_2_4_2  along with the NXT-G 2.0 to 2.1 patch.

The firmware doesn't have instructions with it in the zip file.  It's really quite simple.  You just make sure the firmware is in the right directory on your PC.  Fire up Mindstorms.  Connect your robot with a USB cable.  And then use the Tools menu choice, update NXT firmware, to do the upgrade.

1. On my PC the firmware goes in "C:\Program Files\LEGO Software\LEGO MINDSTORMS Edu NXT\engine\Firmware".  Your's should be something similar depending what version of NXT-G you are using.  You want the unzipped file "LEGO MINDSTORMS NXT Firmware V1.31.rfw" in this directory.

2. Directly hook your brick to the PC via a USB cable.  You can't do this via Bluetooth.

3. In Mindstorms on your PC go to Tools -> Update NXT Firmware

4. Select the 1.31 firmware from the "Available Firmware Files:" and click "Download"

5. Wait until all 3 progress bars are done.  Don't unplug it early.

6. You're done.  EASY!
