Terminal Update Instruction
 (for Terminals Unable to Connect to VHQ)

If your payment terminal cannot connect directly to the Verifone VHQ system, you can perform a manual update using a USB drive. The update consists of two main parts: installing the ADK file and installing the VHQ configuration file. Please follow the instructions below carefully.


Step 1: Prepare the Update Files

  1. Download the following files:

    • ADK File: dl.adk-4.7.23.4-1606-vos2-engage-prod.tgz
      (Download button is in the upper-right corner of the provided page link)

    • VHQ File: Forte-vhq.verifone.com-3.2.6_Config_Engage_noema.tgz
      (See attachment below)

  2. Copy both files onto a USB drive.

    • ⚠️ Important: The USB drive must be small enough to fit into the port located on the bottom of the terminal.


Step 2: Install the ADK File

  1. Ensure the terminal is powered on.

  2. Insert the prepared USB drive into the terminal’s USB port (bottom of the device).

  3. Enter Admin Mode:

    • Press 1 + 5 + 9 at the same time until the menu appears.

  4. Navigate through the menu:

    • Scroll down and tap Control Panel.

    • Scroll down again and tap Sysmode.

    • Tap Supervisor.

    • Enter your Supervisor password.

    • Select USB Memory.

    • Choose the file: dl.adk-4.7.23.4-1606-vos2-engage-prod.tgz.

    • When prompted “Start Install?”, tap OK.

  6. The installation will begin.

    • A progress bar will appear.

    • The terminal will reboot multiple times during this process.

    • Total installation time is about 5 minutes.

    • Once completed, the terminal will return to the main screen.


Step 3: Install the VHQ File

  1. Enter Admin Mode again:

    • Press 1 + 5 + 9 at the same time.

    • Scroll down and tap Control Panel.

    • Scroll down and tap Sysmode.

    • Tap Supervisor and enter your password.

  2. From the Supervisor menu:

    • Tap Update.

    • Select USB Memory.

    • Choose the file: Forte-vhq.verifone.com-3.2.6_Config_Engage_noema.tgz.

    • When prompted “Please confirm…”, tap OK.
