Android STB Firmware Update (OTA)

Update in Automatic Mode

The STB firmware update in automatic mode is performed as follows:

1. STB boots up.
2. After 10 minutes, STB checks for a new firmware version on the update server.
3. If there is no new version on the server, the next check will occur in 10 minutes.
4. If there is a new version on the server:
   1. The firmware is loaded in background mode.
   2. Before installing, the STB reboot confirmation dialog pops up on the screen:
      1. If the user agrees, STB reboots and installs the new firmware;
      2. If the user refuses, the dialog pops up again after a while (usually after 2 hours).

Manual Update from Update Server

In order to update the STB firmware from the update server manualy go to the Home screen of the STB client application —> Settings —> About device —> System update (menu section writing may vary).

The link to the update server is embedded into the STB firmware and usualy has the following URL: http://customer_firmware_update_server/android/check_version_ext
