The current system is 6.11.5. The system cannot be accessed after restarting, but ssh and wireguard can be used. After connecting to ssh, enter "/usr/local/sbin/emhttp&" to open the web, but it is in English. The language pack needs to be downloaded and installed again.
I think it may be related to the USB flash drive, so I changed the USB flash drive, redo the system, and copy the config to cover it. The result is still the same. Connect TV and see the following figure. The system is downloading a 16.8M file. The speed is very slow, resulting in no access to the system. Who knows why?
