# Panasonic TH-40HS550K (Skyworth-built, GS655, codename shibuya, MediaTek m5621), Android TV 11 (API 30), firmware RTO9.240708.002 (12195242) # Vendor fingerprint skyworth/SW1_T/shibuya. armeabi-v7a, UI at 1280x720, about 0.9 GB RAM. # Classic Android TV home, not Google TV: the stock launcher is com.google.android.tvlauncher. # # Stock launcher: com.google.android.tvlauncher # Live TV app: com.mediatek.wwtv.tvcenter (Live TV and the input panel; keep it) # Never disable any com.mediatek.* package: they are the tuner, input and HDMI stack. # # Apply: TV_HOST= tools/disable.sh examples/panasonic-th-40hs550k/debloat.txt # Undo: TV_HOST= tools/restore.sh examples/panasonic-th-40hs550k/debloat.txt # Everything is DISABLED, not uninstalled. Comment out any line you want to keep. # # Disabled before this debloat, so not listed (restore.sh would turn it ON): com.google.android.marvin.talkback. # # Status: disabled in four batches on one TV on 2026-10-19, with a screenshot after each batch and remote-key # checks of Home, Live TV, the input panel and HDMI detection. Nothing broke in that testing; the list had # about a day of real use when submitted, so treat it as a starting point. # # Quirks on this firmware, all checked on the TV: # - Only the stock launcher and Settings' FallbackHome claim HOME; setupwraith does not. A sideloaded launcher # installs and can be set as home with `cmd package set-home-activity`, no signature check. # - Screenshots: `exec-out screencap -p` mixes "Init wrapper sys mutex" / "open mma dev failed" lines into the # PNG. Write to a file with `screencap -p /sdcard/s.png` and pull it. While Live TV or an HDMI input is on # screen the file comes back empty (protected video layer). # - The TV powers on to the last source (Live TV or an HDMI port). TV Settings contains a "Power on behavior" # string but this firmware shows no menu for it. # - HDMI-CEC devices appear as child TV inputs, so the input list can show "HDMI 1 PlayStation 5". # - Disabling partnercustomizer (below) removes the Inputs and Wi-Fi icons from the stock launcher's top bar; # irrelevant once launcher/ is home. The stock launcher also keeps a Play Movies tile after # com.google.android.videos is disabled: it is a built-in shortcut, not the app. # - About 0.9 GB of RAM: the low-memory killer ends background apps (Netflix included) quickly. # Skyworth auto-installs, shop demo and setup leftovers android.autoinstalls.config.skyworth # Play Auto Installs config for preloaded apps fusion.android.tv.demo # Skyworth retail demo service, starts at boot com.smartdevice.common.demonow # "Demo Now" store demo app com.mstar.android.tv.disclaimercustomization # disclaimer screen used only by the first-run setup com.Smartdevice.emanual # on-screen manual (E-Manual) # Telemetry and background services com.google.android.feedback com.google.android.apps.nbu.smartconnect.tv # Google background data service (registers a VpnService), starts at boot com.mediatek.testpq # MediaTek picture-quality test tool, starts at boot # Recommendation rows and stock-launcher partner config com.google.android.tvrecommendations com.google.android.leanbacklauncher.partnercustomizer # see the top-bar quirk above # Not used (by choice) com.amazon.amazonvideo.livingroom com.google.android.videos # Play Movies & TV com.google.android.play.games com.mediatek.wwtv.mediaplayer # the "Media" tile: plays files from a USB drive com.google.android.katniss # Google Assistant / voice search com.airoha.ble.ota # "RC Upgrade": firmware updater for the Bluetooth remote; pairing still works # Stock launcher, replaced by launcher/ # com.google.android.tvlauncher # launcher/build-and-install.sh disables the stock launcher itself, after Home has moved # Kept on purpose: com.mediatek.wwtv.tvcenter / com.mediatek.tvinput / com.mediatek.tv.service (Live TV, HDMI), # com.mediatek.network (persistent network monitor), com.coocaa.factory (Skyworth factory service; boot # receiver, left alone), com.google.android.tv.remote.service, Bluetooth, Gboard, Play Store, Play Services, # com.google.android.apps.mediashell (Chromecast) and com.google.android.backdrop (ambient screensaver) by choice, # YouTube, YouTube Music and Netflix by choice.
