Oh no, sorry to hear that. Let's see what we can do to resolve that.
So as not to be redundant and streamline the process, what have you attempted already to unbrick the VOXL's?
Could you also provide further information on the board as well as what you were attempting to do before the VOXL's bricked? eg. software version, setup, camera config, computer setup, usb cables, power management, etc. The more information you can provide, the better we can help you.
