# Live hardware session with manual ADB; not an end-to-end run of all.sh/verify.sh.
status: partial
tested_on: "RTT2.220118.001"
models: []
adb:
  port: 5555
  transport: wifi
  first_connection_prompt: >-
    USB debugging alone opens TCP 5555 on this build; no Wireless debugging
    pairing code was needed. The first adb connect shows "unauthorized" until
    the TV's "Allow USB debugging?" dialog is accepted.
developer_mode: >-
  Settings > System > About > Android TV OS build > press OK seven times.
  Then Settings > System > Developer options > USB debugging: ON.
ip_location: "Settings > Network & Internet > the connected Wi-Fi network"
prompts:
  - name: "Allow USB debugging?"
    when: "first adb connect from a new computer"
    blocks_automation: true
    fix: >-
      Accept on the TV with the remote, with "Always allow from this computer"
      ticked. Later connects need no prompt, including after a reboot.
data:
  packages: data/androidtv/packages.txt
  protected: data/androidtv/protected.txt
  never_disable: data/androidtv/never-disable.txt
  user_apps: data/androidtv/user-apps.txt
launcher:
  package: tv.dumbtv.home
  reason: >-
    launcherx holds HOME at priority 2 and setupwraith at 1. dumbtv home 1.1
    (release APK, checksum ok) took HOME after pm disable-user of
    com.google.android.tungsten.setupwraith and then
    com.google.android.apps.tv.launcherx. No accessibility Guard and no
    alarm_manager_constants change were needed.
  fallback: >-
    com.android.tv.settings answers HOME at priority -1000, so with both
    disabled and dumbtv home missing the TV lands in Settings rather than a
    blank screen.
  quirk: >-
    LEANBACK_SETTINGS does not resolve on this build, so the Settings chip
    falls back to android.settings.SETTINGS, which opens the real TV settings.
quirks:
  - >-
    Google TV "Apps only mode" removes the recommendation rows but keeps a
    "Sponsored" hero banner at the top of the home screen. The logcat hosts
    around it are tv.google.com and play.googleapis.com, which the launcher and
    Play Store also need, so DNS cannot strip the banner. Replacing the launcher
    is the only fix found.
  - >-
    adb exec-out screencap -p produces a corrupt PNG: the vendor screencap
    prints "Init wrapper sys mutex successful" and "open mma dev failed" on
    stdout first. Write to /data/local/tmp and adb pull instead.
  - >-
    discover.sh flagged 0 of 136 packages. Hisense and MediaTek bloat uses names
    like com.hisense.service.message (promo notices) and com.hisense.storemode,
    which its patterns do not match.
  - >-
    The UI layer reports 1920x1080 in dumpsys display. Video still plays at 4K.
    HDR types 1-4 (Dolby Vision, HDR10, HLG, HDR10+) and ARC DD+ with Atmos
    were unchanged after the session.
  - >-
    Private DNS works with no app: settings put global private_dns_specifier
    <an ad-blocking DoT host> plus private_dns_mode hostname. dumpsys connectivity
    showed it validated, and ad hosts resolved to 127.0.0.1 after a reboot.
notes: >-
  Tested on a real TV on 2026-10-21 with manual ADB. Disabled for user 0, all
  re-enableable: com.hisense.storemode, fusion.android.tv.demo,
  com.google.android.feedback, com.google.android.play.games,
  com.hisense.service.message, com.hisense.alexa, com.google.android.katniss
  (voice search goes with it), com.google.android.tungsten.setupwraith,
  com.google.android.apps.tv.launcherx. No PROTECTED or failed disables. The
  first seven survived two reboots; the launcher swap survived the one after it. Netflix launched
  from dumbtv home and HOME returned to it. Device codename songshan.
known_limits:
  - "One TV and one firmware build; other Hisense Google TV models may differ."
  - >-
    all.sh, debloat.sh and verify.sh were not run: debloat.sh refuses non-Amazon
    hardware, and verify.sh checks Fire OS hosts. An ad-blocking Private DNS
    resolver was used instead of personalDNSfilter.
  - >-
    data/androidtv/packages.txt is still unpopulated. The disables listed in
    notes are one household's choices, not a removal list for other TVs.
  - "Firmware OTA services (com.hisense.tv.ota, com.hisense.remoteupgrade) were left enabled."
