First of all, you need to install the driver, which is usually signed, so you have to go to the next visa-free tool. After installing the driver, download the font file on the computer and install it in the mobile phone. It depends on which disk you install the driver on, and then put the font file in the Fonts folder on the C/E disk (I am x6, too, and my driver is stored in mass storage, so I put the font file in E: Data/Fonts).

If you follow the above steps, there should be no problem. See if you're mistaken.
