Hello,
I was doing the upgrade to firmware v10, I did everything that the site said: the robot was fully charged, the only programmed open was firmware upgrader, and I just had downloaded the last version of the programs. I started the process, everything was OK until the upgrader reached 90% that it showed me a message saying that a critical error has been presented, I clicked Ok and after that Windows was not capable to establish a continuous USB connection with the robot. I unplugged the robot and try to plugged again and nothing. I have also tried with a different USB cable but nothing. So I decided to try in Ubuntu 15.04, I downloaded the programs and see what happen, and I got the same problem, Ubuntu is not capable to have a stable connection with the robot. Ubuntu and Windows detect the robot but after some seconds it disconnects. When the robot is plugged to the computer a red led near the USB port turns on, and after some time in changes to blue. Additional to this, the robot is unresponsive, I cannot turn it on. There is any solution?
