# Alwtniet HY320 Mini projector (device adt3, Askey; Allwinner/HTC firmware), Android 11 (SDK 30) # Firmware UI_Veng.projector.20250117.194417, 1280x720 panel, ~1 GB RAM (ro.config.low_ram=true). # Same firmware family as examples/portronics-beem-470/ and examples/magcubic-hy300-pro/, older build. # The firmware reports the generic "ADT-3" / "adt3" / askey identity: match on the build string, # or on ro.product.model=HY320Mini. # # Apply: TV_HOST= tools/disable.sh examples/alwtniet-hy320-mini/debloat.txt # Undo: TV_HOST= tools/restore.sh examples/alwtniet-hy320-mini/debloat.txt # Everything is DISABLED, not uninstalled. Applied 2026-10-21 and lived with since: Wi-Fi, the # remote, YouTube and Spotify keep working, and the launcher (STOCK_LAUNCHER=none) owns Home. # # Getting ADB: Settings > About > press OK on "Build number" seven times. This firmware says # "Setup mode turned on" rather than "You are now a developer". Developer options is then under # System; USB debugging opens port 5555. ro.adb.secure=1 (the Allow prompt appears). # # Kept on purpose: # - com.htc.htcsettings: the projector's own settings (keystone, focus, picture). # - com.htc.closedialog: the power-button menu (it holds REBOOT and SYSTEM_ALERT_WINDOW). # - com.hotack.writesn: factory serial/MAC writer that starts at boot. Left alone here, as # disabling it while connected over Wi-Fi risks losing the connection. # - com.android.nfx (NFXAccessibility, v1.1.3, updated in /data): left on here; the Portronics list # disables it without issues. # - com.htc.htclauncherhighenglishd08: the stock Home. build-and-install.sh does not recognise it, so # run it with STOCK_LAUNCHER=none; set-home-activity takes Home and the stock one stays as fallback. # # Firmware notes: # - The panel is 1280x720 but ships at density 240, which gives apps an 853x480dp screen. TV apps and # the launcher are laid out for 960x540dp: `wm density 213` (undo: `wm density reset`) fixes the # cramped layout. # - Low-RAM device (about 30 MB free with apps running), yet Android still allowed a notification # listener (`cmd notification allow_listener`). # - The unit arrived with unofficial streaming apps in the user partition, not the system image # (HDO Box, a "Cinema HD" build as com.yoku.marumovie.analytics, Sports Zone, UKTurks, StreamFire, # Drama Player). A factory reset removes them; they are not listed here because this list only # disables. com.hotack.silentsdk (the dropper on some H713 units) is not present on this build. # HTC ad overlay, telemetry and app store com.htc.expandsdk # starts at boot, draws over apps (SYSTEM_ALERT_WINDOW) and uses the internet com.htc.eventuploadservice # usage/event uploader com.htc.storeos # HTC app store # Firmware updaters, disabled on the tested set (uncomment all three to do the same): this unbranded Allwinner/HTC firmware takes OTA images from # an unknown vendor server, and projectors in this H713 family have shipped firmware with preinstalled # droppers and adware, so this owner chose no silent firmware changes. Re-enable all three to check # for firmware updates. # com.htc.htcotaupdate # com.softwinner.update # Allwinner OTA # android.rockchip.update.service # Rockchip updater left in this Allwinner image # Factory and burn-in test apps com.htc.hyk_test com.softwinner.agingdragonbox com.softwinner.dragonbox com.softwinner.dragonatt # Preloaded store for another brand's devices com.huawei.appmarket # Huawei AppGallery, installed in the user partition on this unit
