With it timing out during a write calibration, it just means no calibration has been loaded, the operating system is still there. I suspect it's not bricked, but I really can't say for sure. Other people here have more experience with this than I do. I do know, that this has happened to me a few times with my 2014 Camaro e38. A new USB cable fixed it for me, but I can't say it will work for your specific situation.
