Hello, I have a DS-KV8113-WME1 door station bell.
Now I wanted to go back to the first firmware V2.2.53_210907 with TFTP.
Now it just flashes white on off on off.
Does anyone have an idea how I can get this fixed?
I thank you in advance.
Greetings Micha

Unfortunately I have to translate it via Google because I don't speak English

I do not know if this is possible. If you can use wireshark you can check for tftp activity during the boot phase.

what language do you speak?
