You need to download the file - it should be a .zip file.
Once you've downloaded it, you need to extract it. Open the zip file and in there will be a folder called "zgemma".
You need to copy this folder to the USB drive.
Once the folder is copied, insert the USB into the REAR usb port on the H2H.
Power on the box from the rear push button- the H2H will then say either "FLSH" on the LCD display, or "USB".
- If it says "FLSH" your box is flashing the software which takes a few minutes
- If it says "USB" you need to hit the silver power button on the front whilst it says "USB" - this will switch it to "FLSH".
If you don't see FLSH or USB your USB drive isn't setup correctly.
