Tried upgrading a ER605 v1 from firmware 1.3.0 Build 20230511 Rel.51317, fails
Both from the prompt/ using the auto-upgrade, as well as manually.
Same error both times - autoupgrade error is " [Failed]Failed to upgrade xx-gateway to firmware version 1.3.0 Build 20230511 Rel.51317 online." (using the firmware that the device suggests)
Manual error is "[Failed]Main Administrator xx failed to upgrade xx-gateway manually. " (using firmware from https://community.tp-link.com/en/business/forum/topic/647338)
Have tried rebooting. Still fails.
How did this pass QA?
it looks like it went well for me without any major problems this time. I don't have a local controller, the controller is somewhere else and is connected via wan. I don't know what your setup is like?
it is a bit more work but you can delete the router from the controller and upgrade in stand alone to see if you can do it then.. when it is upgraded you can adopt the router into the controller again.
