Xiaomi Miwifi R1d In Safe Mode

Hello guys, I need help with my router R1D. Version of system is 2.1.8 developer edition. Router is in safe mode with system boot failure, light blinking red. I am not able to flash ROM to the new one automatically, or another version manualy. Router worked well for a year and now this issue.
Do you have, please, any idea how to fix this?
Thanks in advance.
