Hi, today I upgraded routeros from 6.45.5 to 6.45.7 and router entered in a boot loop. I tried netinstalling back to 6.45.5, 6.40.8, 6.42.12, 6.43.16, 6.44.3 and every time it flashes correctly but goes back to bootloop. Tried also other working power supplies with no luck Thanks in advance for any ...
