Just been looking over at UMI¡s main web and they've changed the rom info for the max mini, now it states Cyanogenmod v11, not v12 and Android 5.1 is not even on there anymore only 5.0.

Is there a chanhlog to see a difference if any) between v100 from 25.9. and v100 from 19.10.
Chec ...
The 25.9. version permanently collapses if you try to access the recovery. That even happens if you initiate a factory data reset in the running Android. Version 19.10 is safe with working stock recovery. No other changes are known.
