Restoring, fixing or upgrading Xiaomi Mi MIX 2S can be easily done using the firmware in this post. Aside from repairing any software associated fault on your smartphone, the fastboot ROM can be used to migrate from Beta to Stable ROM (and vice versa). To put it simply, this firmware will guide you through restoring your device to its default factory state.
If you currently have a rooted device and/or modified other partitions of the phone, flashing the Fastboot ROM will overwrite all existing modified partitions and replace with factory software. So, you should ensure to backup all important data on the phone- like contacts, messages, app data, etc. It is very necessary, to avoid loss of data after flashing.
Also, charge the device battery to at least 40% so that the flashing process will not be interrupted by low battery. Interrupting the firmware installation process could damage your phone.
From the links below, download either the Fastboot or Recovery firmware and follow the recommended flashing instructions afterwards. Do not hesitate to report any broken links detected.
