I just updated my cr1000x OS to 8.02. After updating the OS through device config without connecting to my PC, the power light flashes and then remains on. I then try to connect with device config, but it can not find the pack bus address. Presumably, all the setting reverted to factory default, so the pack bus address may no longer be there. I cannot connect directly or with IP.
Easiest way to get back into it is direct USB with Device Configuration Utility. The only thing that would block that is some security settings, which are off by default.
