NOTE: You may start to see EVT_AP_RestartProc events in the controller log. If you see these, please report if there is anything specifically in your setup that triggers the events. The processes restarting is not new, but the reporting of the restarting is, and we are using these reports to clean up these issues.


IMPORTANT NOTE: In preparation for an upcoming code merge, we've updated the minimum firmware version to 3.9.42 for certain hardware. That means if you flash this firmware onto any HD/SHD/XG/BaseStationXG then you will not be able to downgrade to firmware prior to 3.9.42. 



*This firmware is meant to be a one file solution that works with all models of UniFi switch. You can use it when upgrading from 3.9.40+ only. It will not work when upgrading from earlier releases.


Any and all feedback is welcome, including lettings us know about successful device upgrades. When reporting an issue, please ensure that you include the following information:

  1. Controller version.
  2. Firmware version (previous and current). 
  3. Device model(s). 

Links are all HTTPS. This assumes your device(s) are currently running at least 3.7.51, and that the device's date is properly set (i.e. it can reach a NTP server). If you encounter issues with the upgrade, or your device isn't on a minimum supported firmware, then you can change the link to HTTP before performing the upgrade.
