Thank so much !

Here is the guide from 4pda for firmware downgrade :

1. Download the necessary firmware (appropriate version, full or incremental) below the link;
Download:
Yandex MiBOX3S_queenchristina_r198.zip
https://yadi.sk/d/aETJG42mvky3Y
the md5: 3c2da1f127fbbfe7fb81eb77338d7423

Yandex MiBOX3S_queenchristina_r145.zip
https://yadi.sk/d/UVgpzJgjvhCpy
the md5: 1c179a334046d1723bf86557d8ef96ae

2. Unrar any downloaded file archive;

3. Copy files update.zip and xiaomi_update on the USB-stick not more than 32Gb and formatted in FAT32 format
4. Connect a USB flash drive into the USB-port of consoles:
➾ for Mi Box 3/3 for USA / 3S using a standard USB port;
5. Go to recovery:
➾ Unplug power of the Mibox when it still operate
➾ For Mi Box 3S (remote IR) press and hold the " Home " + " Menu " button on the remote, and supplies power to the Mibox. The process of "firmware" will start automatically (the Chinese hare screen will repair androjda), after finish the Mibox will restart automatically;

USB port stop working because ADB on. You can connect Mibox and PC to run adb command.

When ADB off, USB can re-use
