It seems you're encountering an issue where the file /data/user/0/me.bmax.apatch/patch/bootctl cannot be found, which is necessary for OTA installations. However, rebooting using the standard OTA updater app works fine. The error message indicates a failure to connect to the boot HAL, suggesting a possible issue with the boot control process rather than the HAL itself. Here are a few steps to address this issue:

  1. Verify File Path and Permissions: Ensure that the file is indeed located at /data/user/0/me.bmax.apatch/patch/bootctl and that the necessary permissions are set for the OTA updater app to access it.
  2. Check OTA Update Integrity: Sometimes, OTA updates can get corrupted. Verify the integrity of the update package and try reinstalling the OTA update.
  3. Manual Slot Switching: If the system prompts you to manually switch slots, do so. This can sometimes resolve issues with boot control by ensuring the correct slot is being used.
  4. Review System Logs: Check the system logs for more detailed error messages that can provide additional insights into why the file is missing or inaccessible.
  5. Update or Reinstall the OTA Updater App: Ensure that the OTA updater app is up to date. If it's outdated or corrupted, reinstalling it might resolve the issue.
  6. Consult Documentation or Support: If the problem persists, consult the documentation for your device or reach out to the support team for assistance. There might be specific instructions or patches available for your device model that can resolve this issue.

By following these steps, you should be able to identify and resolve the issue with the missing bootctl file during OTA installations.
