[3] SOFTWARE UPGRADE PROCEDURE
1. utv upgrade: (Now it’s only available for secured TV)
For utv upgrade, you’ll receive a file with the extension (*.utv) and a text file
“updatelogic.txt”. The content of “updatelogic.txt” is the file name of the utv
file.
For example, if the utv filename you got is “V1.34.23-SEC.utv”, the content of
“updatelogic.txt” will be “V1.34.23-SEC.utv”.
Steps to upgrade:
a. AC on and DC on to power on the TV.
(You can see the OSD or Video on the screen)
b. Put “V1.34.23-SEC.utv” and “updatelogic.txt” these two files in the root
of the USB flash.
21
c. Insert the USB flash to the USB port of the TV
d. Wait seconds then you’ll see OSD message like below indicating the
firmware upgrade is in progress.
e. After the executing accomplished, TV will reboot itself.
f. After TV reboots, you’ll see the OSD message like below indicating the
TV is installing a new firmware.
g. TV will show you current Version of TV and what version of firmware
22
you’re installing.
h. After the installing progress complete, TV will restart itself again. And
now the utv upgrade is accomplished. You can go to
“Menu
SystemSystem InformationVersion” for version number
to check if the firmware upgrade is successful.
2. Fs.sys/safe-kernel.img1/ update_demo.tgz upgrade:
For Fs.sys/safe-kernel.img1/ update_demo.tgz upgrade, you’ll receive a
Fs.sys/safe-kernel.img1/ update_demo.tgz file and the file name must be
“Fs.sys/safe-kernel.img1/ update_demo.tgz”. However, for a secured
firmware upgraded by Fs.sys/safe-kernel.img1/ update_demo.tgz, this TV
must be“re-registered” on the production NOC of ULI. You need to provide
the serial number shown on the “MenuSystemSystem
InformationTV
SN” to us. We’ll ask SX or Vizio for help to re-register this TV.
Upgrade steps:
a. Prepare a USB flash and place the file “Fs.sys/safe-kernel.img1/
update_demo.tgz” in the root of the USB flash. (No other
Fs.sys/safe-kernel.img1/ update_demo.tgz file can be placed in the root.
