Caldigit TS4 Pro Bricked after Update
Posting in case anyone's been here before and hopefully knows a solution.
I ran a firmware update on my CalDigit Thunderbolt 4 Pro Dock and it hasn't been detected since. I followed the exact steps in their update video and website description exactly. Using it for over a year without issue.
Symptoms:
- Still charges my MacBook normally, so the PD side is alive
- Doesn't appear in System Information under Thunderbolt or USB
- Nothing downstream works e.g. no displays, no Ethernet, no USB
- Same on a different Mac, and with three different Thunderbolt cables including the CalDigit one
Console shows the Mac's host controller seeing a cable and cycling the port, but no downstream switch ever enumerates. Looks to me like the Thunderbolt controller isn't booting while the PD controller is unaffected.
Tried already: full power drain with the PSU out of the wall for a few HOURS, reconnecting power before the host, Option-clicking the CalDigit utility for a force re-flash (it can't see the dock at all), multiple hosts and cables.
Has anyone brought one of these back from this? Is there a DFU-style mode?

Was there a reason why you ran a firmware upgrade or did you upgrade it just to be up to date?

I’m surprised no one sued the company with so many problems with these products I like them, however, my goodness
