System is dead :(
If you continuously cannot connect to the Rover access point or there's no access point after several resets - it may mean that the system is just dead.
This may be caused by too many force power offs during the Rover operation.
To fix this, please proceed to software flashing tutorial.
To make sure it doesn't happen again, read carefully and remember to turn off the Rover the right way every time as described in the link:
