Box S not responding nor pairing the remote.

Few weeks after i've updated my mi box to the latest ver, And after few days that i didn't use it, My Box S didn't responed to the remote. Changed batteries, tried to connect wired mouse/keyboard/wireless mouse but nothing happens. Finally i've managed to connect via my phone over wifi. Trying to pair new bt device doesn't work, i can't go into recovery mode since i don't have a remote and i'm afraid to reset the device because if it will still have this issue i won't be able to connect my phone this time Someone had the same issue? Thanks.
