Factory Reset C-5 on Firmware 2.3.8.118 (Diagnostic Tool stuck on version 1.0.92)

[672southmain]

See this post for how to force a diagnostic tool update.

On 2.3.3.121, can't soft reset, can't upgrade diagnostic tool

Run http://your.hubs.ip.here/hub/cloud/updateDiagnosticTool endpoint to force diagnostics tool update. It will take a few minutes with zero feedback but will come back with a simple meaningful text response eventually. Also, you shouldn't need to preemptively soft reset to update to a new version.

Factory reset has nothing to do with diagnostic tool update. Have patience, it sometimes takes a VERY long time for update to arrive.
