If the APK will not download
- Reload the page on a stable network and confirm the gateway did not open an unrelated host.
- Check the browser's download permission and available device storage.
- Look in the browser download list for a blocked, paused or failed item.
- If the server returns an HTML page instead of an APK, do not rename it; report the broken release path.
- Avoid repeated downloads from different mirrors because that makes file identity harder to establish.
If Android will not install the file
- 01
Confirm the file
Check the extension, size and SHA-256 against the release record. A partial download should be deleted rather than retried from the installer.
- 02
Check compatibility
Compare the release's minimum Android version and CPU support with the device. Those release fields are not available in the supplied material today.
- 03
Check the existing app
An older BONU7 build with a different signer can block an update. Preserve account access and local data before considering removal.
- 04
Use the narrow permission
Allow the exact browser or file manager to install this package, then switch the permission off after the attempt.
What to collect for support
- Phone model and Android version, without device serial or advertising ID.
- Exact error wording and the step where it appears.
- APK filename, file size and SHA-256.
- Source URL and final download host, with sensitive query tokens redacted if needed.
- Installed BONU7 version and whether this is a new install or update.
Frequently asked questions
Can I fix a parse error by renaming the file?
No. A real APK must contain a valid Android package. Renaming an HTML, ZIP or incomplete file does not make it installable and hides the real source problem.
Why does an update say it conflicts with an existing package?
The application ID may belong to an installed app, or the new APK may use an incompatible signer. Compare package and signer information before removing anything.
