VOXL mainboard appears to be dead

[kiprock]

Hello,

Yesterday the voxl main board stopped responding. I removed all cameras and devices except for power and cannot get adb shell to respond.

If I do adb devices, I get a device in the list, but when i try adb shell, I get error, closed.

I attached the fastboot interface and tried following the unbricking procedure described at https://docs.modalai.com/unbrick-voxl/ but no response.
