USB flash drive 
Any normal USB flash drive will work, provided it has a FAT-16 or FAT-32 file system 
format. (This is the default for most flash drives.)  
The size of the download is small—usually less than 100 MB—and so will fit on most any 
size flash drive you might have. 
 
4.  When the download finishes, take the USB flash drive to the TV and plug it into 
the USB port. When you do, the TV validates the files on the flash drive and 
displays a 12-digit code.  
5.  Write down the code and the web address, and take this information back to 
your Internet-connected computer.  
6.  On the 12-digit code page, enter the code your TV displayed, and then click Next.  
7.  On the 6-digit code page, write down the 6-digit code that appears, and then 
take it back to your TV. 
 
12- and 6-digit codes 
The USB update process uses a pair of codes to validate that you are authorized to 
install an update, and to ensure you are not attempting to install an old, unsupported 
version of the system software. 
 
8.  Using the TV remote, select Next to move to the next screen, and then use the 
on-screen keyboard to enter the 6-digit code. When finished, select OK. The 
system update begins. Do not remove the USB flash drive until the TV restarts. 
When the update finishes, the TV restarts. You can check the new version number by 
navigating to Settings > System > About.
