I try to update the firmware but it shows me the error " **There was a problem connecting to the Robot Brain.First make sure no other programs are connected to it, then unplug it and plug it back in to try again **" but I didn’t have any program who connect to the brain except the “VEX IQ firmware update” and now the brain is not working. the only thing shows on the screen is vex lego.
how can I fix it
mamalisaranjam,
There is an issue with the early version of firmware which causes the user programs in the catalog to get corrupted. We have a fix in work to ensure this doesn’t happen with future versions (still going through testing) and we have a procedure to help recover your brain from its locked up state.
