My Vectrix started suffering from the problem described here:

Basically, it interrupts power momentarily, which causes me massive chills!, and then it continues with reduced power and the yellow wrench lighted up. Has soon as I stop, the red battery light comes on.

According the latest comments in the mentioned thread, the MC firmware version here contained still has the described bug, i.e., the MC cooling fans do not restart after the 'UpRst' error.

Where can I get the a MC firmware without this bug ?

Thank you,

Ricardo de Matos
