My 4c has been working perfectly up to this point. It started updating the new firmware that was deployed, and that’s when this started.
Firmware update either gave up or crashed. Now it’s bricked. Driver doesn’t see it. Have tried rebooting, reconnecting, moving it to a new port. Lights are on, but the device doesn’t respond. Tried removing/reinstalling drivers and software to no avail. It appears that the failed firmware update bricked the device.
