I got my 2 bean+ from KS. This morning, after upgrade firmware one of them is ok, but other got problem.
The sketch on Bean+ still working since the led is on when I shake it but bean loader cant find it (on Windows, iOS or Android). The only time it appear is when the power on and then it disappear.
Any one face this issue before? I tried to reset with RST pin to GND but still the same.
