Yeelight LED Color is blinking and can´t be accessed any more. It can´t be restored too

My lamp started to blinking and it can´t be restored using factory reset procedure.This firmware is corrupted I think. How can I fix it?

I tried to reset, turned it off for a long time and turned it on and it just flashes.My app screen says it has a latest firmware but I don´t know what is this version.

What can I do to solve this. Is it possible to access it via telnet and send firmware via tftp server? That lamp can´t get any IP address anymore.
