SparkMAX blinks magenta, but it looks weird

I’ve been testing my team’s NEO Motors, using REV Hardware Client. The first SparkMax used on tests blinks magenta (brushless color) with no problem, but some trouble and fail tries happened:

  1. NEO was power on, but it made a strange noise and a lot of stalling while turning;
  2. NEO never start to spin, even if I change the percentage of motor controller in Hardware Client.

Any tips to fix this? Or is my SparkMax bricked? I already try to set at the Recovery mode (reinstall the firmware), and restored it to factory default. I have a little impression of electrical smell inside motor controller too.

Yeah, if I change to another SparkMax, the NEO works without problems.

Sometimes the pins in the port that connect the spark to the neo can get bent. That causes problems.
