### Updating via TF Card or Thumb Drive

1. **Folder Creation:**
   * On a TF Card: Create a folder named **'\wizarpos\homesettings\homesettings\_XXX\\**'. 'XXX' usually is 'wizarpos', aligning with the **'ro.wp.logo**' property value. Or the same with Thumb Drive as below.
   * On a Thumb Drive: Create a folder named **'\cloudpos\config\\**'. This requires PosSysAssistant app version greater than 2.11.8.
2. **Copying the File:**
   * Copy **'possystemsettings.xml**' to the created folder.
   * The update process follows the same steps as installing an APK from a TF card or thumb drive.

### Updating via WizarView

1. **Upload to WizarView:**
   * Add a new parameter file named **'possystemsettings.xml**' in WizarView.
   * Navigate to Applications > Application.
   * Click the '+' icon to open an edit window.
   * In the edit window, input the required details and select 'param' type.
   * Enter the package name (**'com.wizarpos.possys**') and the file name (**'possystemsettings.xml**').
   * Click 'Commit'.
2. **Configuring the File:**
   * In Applications > Application, click 'Search'.
   * Choose the parameter file from the list.
   * Click the 'config' icon, then 'Upload'.
   * Select the file to upload and click 'Commit'.
3. **Pushing the Configuration:**
   * Follow the instructions in the WizarView user manual to configure and push the settings to a terminal.
