Installation and updates

Check the version

The version shown on a development device can be newer than the publicly available download. Check the release label and APK checksum before assuming that a Downloader code contains a particular build.

The public Downloader code is 9509249. On 5 November 2026 its actual download was verified as 0.62.0-dev / version code 66 and matched the qualified release APK. The app version and public download are checked separately.

• Use the APK from the TiviNerd Development preview-build release, or enter code 9509249 in Downloader.
• A download is not an installation. Complete the normal Android installer and then check the version shown by TiviNerd.

Keep your existing setup

The same package identity and signing certificate are required for an Android update. A signature conflict is different from a network failure or a security warning.

1. Use the genuine download address and compare its version with the release you intended to install.
2. Install the newer APK as an update to the existing app. Do not uninstall or clear app storage just to update.
3. After installation, check the app version and verify that your sources and profiles are still present.

If Android displays a warning

Permission for a particular installer to install apps, an unfamiliar-app scan prompt and a harmful-app block are different messages. Record the exact wording and which Android or Google screen displays it.

The older 0.58 APK triggered an explicit Google Play Protect harmful-app block on our Pixel Tablet during an update test. Its precise classification cause remains unknown. Separate preserving-update and fresh-install observations for the exact 0.61 APK passed without disabling protection. Those observations do not diagnose the older decision or certify every device or future release.

• Do not disable Play Protect or follow a bypass instruction to resolve the report.
• Cancel a blocked installation and retain your existing setup.
• Include the exact version, device model, Android version and message in a support report. Never include provider passwords or private source URLs.

Updates offered by the app

Use the update screen when an update is available. Android still controls package installation and its security checks. An app download alone is not a completed installation. Keep the previous setup until the preserving update has been verified.
