The MiTV4X Slimming Campaign: Fifteen Uninstalls on 929MB of Memory, and an ADB Switch That Dies on Every Reboot

A 720p, Android 6.0 Xiaomi TV with only 929MB of memory (107MB free) got a full medical after ADB connected. The Xiaomi TV advertising quartet — push, quality reporting, cloud control and statistics — together occupy about 20MB resident and keep networking. Fifteen packages were uninstalled successfully, expected to free 30-40MB of resident memory and cut all background networking. But after reboot the ADB switch was reset, and persistence改造 also failed: persist properties, adb_enabled and developer_status all set, yet 200 seconds after reboot 5555 stayed closed — this firmware deliberately resets the network ADB switch on every boot.
