How to unbrick a totally dead WD My Cloud Mirror gen 2

Thanks, @Q-Fireball, but it didn’t work also.

My unit is bricked in a weird way. Even if I remove both drives the unit shows solid blue LED for the drives and the power LED keeps blinking blue forever. I’ve opened a thread about it here:

Thanks in advance.
