Hisense SmartTV 4K FFM Debloat List

Notes & quirks on this firmware

• Security patch 2023-02-05. Sold in Latin America; the Android model string is "SmartTV 4K FFM".
• The same device and build ships in the USA as the Hisense U9DG (75" Dual-Cell ULED, 2021), with a
• US preload set: the "US (U9DG)" groups below. 2 GB RAM, armeabi-v7a (32-bit userspace), 7.7 GB /data.
• Everything is DISABLED, not uninstalled. Comment out any line you want to keep.
• WARNING, read before applying: a first version of this list that also disabled
• com.hisense.tv.smartsense, com.vt.tv.smartsense.ui and com.vt.tv.aiot sent the TV to Android
• Recovery on the next boot ("Can't load Android system. Your data may be corrupt"). "Try again"
• booted normally and tools/restore.sh undid everything. Which of the three was the cause is not
• confirmed, so all three are left out below. Never pick "Factory data reset" on that screen
• before trying "Try again".
• This list was then applied in seven groups with a reboot after each: no crashes, normal boot.
• If you experiment with more packages, reboot after each small group, and wait ~15 s after
• pm disable-user before rebooting: rebooting immediately lost the change on this TV.
• US (U9DG), 2026-10-21: the Hisense, Google and US groups applied in five batches with a reboot after
• each, OTA kept: normal boot every time, all 7 inputs (HDMI 1-4, composite, two tuners) still
• registered, HDMI switching from the launcher and Chromecast work. Fresh on that set, not yet lived
• with for weeks.
• ADB: turning USB debugging on opens port 5555 directly (no Wireless debugging pairing);
• ro.adb.secure=1, so the TV asks "Allow USB debugging?" on first connect.
• Input button (U9DG Bluetooth remote, Vendor_000d_Product_3838.kl): scancode 220 = KEYCODE_TV_INPUT,
• which the Live TV app and the launcher's InputKeyService turn into com.android.tv.action.VIEW_INPUTS.
• Nothing on this firmware answers that action once tvlauncher is disabled (no global_keys.xml, no
• vendor input picker), so the button does nothing until the launcher answers it itself:
• handle_view_inputs in config.json in this folder (TV_HOST=<tv ip> tools/theme.sh
• examples/hisense-smarttv-4k-ffm), with INPUT_KEY_SERVICE=1 at install.
• setupwraith (com.google.android.tungsten.setupwraith) owns the Wi-Fi saved at setup but does not
• claim HOME on this firmware, so it stays enabled; launcher/build-and-install.sh worked unchanged.
• Keep: com.mediatek.* (including com.mediatek.wwtv.tvcenter, the Live TV and HDMI app),
• com.hisense.tv.hitvinput, com.hisense.tv.smartservice, com.vidaa.persistent.service,
• com.hisense.tv.customerlauncher. HDMI-CEC and the inputs keep working with this list.
• Stock launcher: com.google.android.tvlauncher (the default in restore.sh).
• Already disabled at the factory: net.vidaatv.android.tv, Pandora, Vudu, Play Games (and on the
• U9DG also Google TV movies, YouTube Music, the Hisense browser and the calendar provider).
• Netflix, YouTube, Prime Video, Disney+, HBO Max, Apple TV, Hulu, Peacock, Peloton, Tubi, Pluto TV.
• Do NOT disable (see warning above): com.hisense.tv.smartsense, com.vt.tv.smartsense.ui, com.vt.tv.aiot Checked with dumpsys and kept because they look tied to the system or features: com.vt.tv.aipq (picture quality), com.hisense.tv.protector, com.hisense.kpad, com.hisense.favkey, com.hisense.uifac, com.hisense.tv.rcs, com.hisense.mixbar, com.hisense.tv.dlna, com.jamdeo.tv.mediacenter (USB media), com.hisense.audio_update_service, com.vt.eula, com.hisense.tv.videocolor.
