WARNING: New Untested Firmware could potentially remove root and break some open source tools.

For some firmware versions it is possible to download them from Xiaomi's CDN directly. The availability of firmware files is dependent of server location and region. Mirrored copies of the firmwares can be found here:

File name convention

• v11_00XXXX.pkg (for all Gen1 firmware and for Gen2 firmware older than January 2019)
• v11_00XXXX.fullos.pkg (for Gen2 firmware newer than January 2019)

A higher number for XXXX does not mean a newer firmware. It seams that there are multiple branches of firmware, sometimes depending on region, some times also dependent on features.
