Roadblox It's more interesting here. Previously, for Android One devices, it was not at all customary to upload images. Yes, there were no images of firmware. People themselves from the logs got direct links to ota updates from the sources I quoted above. Links of this type:
https://android.googleapis.com/packages/ota/google_mi438ssprout_mi438s/1f8376c5ace8f2907746fb8cfb098b35a2052436.zip
As you can see, the link is quite working and the file can be downloaded separately. But for the most part, all these updates were incremental (rarely complete), there were no complete images. So in case of problems with loading it was necessary to rely on backup and its recovery.
Xiaomi decided to spread it, and that's great.
