Hi, I followed the same guide.
I made my app and compile it into a WGT.
Then I create a pkginfo.xml with the following.
<?xml version="1.0" encoding="UTF-8"?>
<pkg name="myapp" type="Kiosk">
<packagever>1.0.0</packagever>
<app>
<apptype>order_web</apptype>
<Existence>1</Existence>
<appfile>myApp.wgt</appfile>
<version>1.0.0</version>
</app>
</pkg>
With these two file. I made a zip (If you are on Mac OS you need to be sure there is no DS_Store and other hidden file), with the name download.zip.
Then made a file usb_kiosk_config.xml
<?xml version="1.0" encoding="UTF-8"?>
<widget>
<zipname>download</zipname>
<domain>https://kiosk_server.samsung.com</domain>
</widget>
And put the download.zip and the usb_kiosk_config.xml in a folder kiosk in the root of your USB key.
You should get this.
.
└ kiosk
├ download.zip # myApp.wgt & pkginfo.xml
└ usb_kiosk_config.xml
Now just plug it into the Kiosk and install it. This should work. If not the problem might be from your wgt.
