6. Run a rollback command (replace com.miui.calculator with the desired package): adb shell pm uninstall-k --user 0 com.miui.calculator Flag -k saves application data, --user 0 applies changes for the current user.

After the reboot, the app will return to the factory version. If the command doesn't work, try adding --user 0 to the end (for some MIUI firmware, this is a must).
