The EV3 brick started by flashing red. Then started where it is stuck on two red buttons. Have changed batteries, and manual reset with no change.

  • Is there any chance that the replacement batteries you put in were already running low? That would explain the red light. Just a thought. – Magnus Apr 11 '19 at 18:53
  • Can you please add more details on when this happens and if it's flashing red? Red flash means batteries are dead, and if problem remains after replacing batteries then it's likely that your EV3 brick is defective. Therefore you should contact Lego at Lego.com/service and get a replacement. Remember to make an account, though! – mindstormsboi Apr 5 at 19:32
