Unsuccessful attempt to install OpenWRT on Xiaomi Mi Router 4A 100M version

Hello, a few days ago I've tried to install OpenWRT on my Xiaomi Mi Router 4A, but it was unsuccessful (I have bricked it). I followed this guide to flash then to try and unbrick. At my first attempt I forgot to change my IP after that one of the lights is turning on and off at intervals of 2 seconds instead of staying always on.

On my second attempt I did everything right, but I don't think it worked. The light turned blue. Now I don't know what to do and I can't access nor of miwifi.com .

Any help is greatly appreciated!

have you done it.,?
