My D3 robot just dead after a week using the latest v4 firmware, although it never give me any problem previously.
Both lights indicator (blue & green) will blinking alternately for about 20 seconds, after that only the green light (battery) will light for about 1 minute before it's turned off by itself.
After pressing the only button for few seconds, and press again the same button, the whole process above will repeat.
Can't find any workable solution right now as mostly to troubleshoot
botvac xv and connected by using USB cable connected to PC to "wake up" the robot, but it doesn't work as well for my D3.
Anyone able to help me with this issue please...... thanks!!
