This section explains how to manually update STB with commands of the System Settings menu in USB mode which intends that the update file (imageupdate) is located on the USB drive connected to STB.

If STB is running the standard factory-made software (Public or Factory image), only the Factory image is permitted to be installed through the Embedded portal.
The last stable version of the Factory image can be downloaded from the manufacturer's server - see Address of update file.

Update file location

The update file (imageupdate) that contained a new (last available) software version is located at the update server. The address (URL) of the update file can be found out via the Embedded portal:

  • Open System settingsSoftware update;
  • In the window Software update that opens, in the Update method option, select HTTP;
  • The URL of the update file is specified in the URL option.

The example of URL value that is specified in standard manufacturer's software versions (Public or Factory image) for MAG322 :

The value of the update file address is stored in STB software in update_url variable.

USB drive requirements and troubleshooting

The USB drive that is intended to perform STB SW update must comply with the next requirements:

  1. FAT32 file system format.
  2. If there is more than one partition on the USB drive, it should use the first one.

Troubleshooting of update from System Settings by USB

'Update by USB' problems, as a rule, related to 1) imageupdate file not found or read on USB drive 2) incorrect software version in imageupdate file. Cause of the problem (error) is described by Status message displayed on the TV screen:

1. 'Check image', Internal error', USB device not found! :

  • Remove and re-insert USB drive in STB.
  • Try to use different USB connectors of STB.
  • Check that the name of the folder and the update file corresponds to an entered value in the Path option of the Software Update window.

    Check extension of the imageupdate file - set Show extension view mode of the folder. Files should not have extensions (like txt, etc.).Probably, there is file accessing issue of this USB drive (especially if you know that the USB drive was used as a boot disk or was handled by a utility like "Partition", etc.).
    • Format USB drive (according to above requirements) and repeat updating procedure;
    • Use partition utilities and make the only one partition on USB flash drive (for instance, use the diskpart utility of OS Windows 10).
    • Replace the USB drive.

2. 'Wrong signature' - Probably used not appropriate type of image:

  • Make sure that the imageupdate file matches your STB model.
  • If you are not sure about the source of the imageupdate file, re-download the file from the server and try updating again.
  • Check up the image type:
    • To Public image you may update from System Recovery Utility;
    • To Factory image you may update from Embedded Portal (System Settings) if your STB runs under control of Public or Factory image.
    • To Custom image of a certain operator, you may update from Embedded Portal (System Settings) if your STB runs under control of the Custom image made by the same operator.
