I tried to update my NXT brick running .7 to the latest version on a freshly formatted computer with Windows 7. After installing all the software, and the NXT drivers, I used the graphical flashing tool. The tool placed the the NXT into firmware update mode, and then Windows selected an incorrect driver ("GPS Camera"). The tool failed with the error "Bad news: An error has occurred lejos.pc.comm.NXTCommException cannot load comm driver."
I exited the tool and selected the correct driver, but the tool still fails with the same error. I'm not sure if there is a way to get the brick out of firmware mode, or if I have to use the Lego Firmware Update tool. I'm hoping you have a solution that doesn't involve the Lego Firmware software, because I don't have the disk at present
Thanks for the help!
