Hello,

This is likely the final firmware from Seiki for their 39" SE39UY04 HDTV with 4K
support @ 30Hz and I wanted to share it for us owners as I'm somewhat happy with
my purchase of it and as it is a discontinued model, Seiki removed public links
to any firmware updates on their website, so I wanted to get a hold of this
before it was too late and Seiki totally stopped supporting it at all even via
tech support over email!

It's dated January 09, 2015 and after installing it via the Service Menu (which
is accessed by pressing Menu and 0,0,0,0), you should see something like this:

The back'n'forth wait with Seiki took about 4-5 days after opening an email
support request on their website. I had to take that screenshot above and ask
for whatever final firmware they had. It would take about a day for them to
respond and I did get a bit frustrated they polled for more information when I
felt the model and serial # was more than enough for them to have already given
me the file by the 2nd day. Anyway, I'm happy I got a hold of this for backup
purposes and to share it for others that would also like to maintain their TV!

* INSTALLATION - Upgrade to Seiki's January 09, 2015 firmware
*******************************************************************************

If you're not familiar with the firmware update process exactly, here are the
word for word simple instructions Seiki provided in their email to me:

Software upgrading instructions:

 *CAUTION: Do not remove the USB flash disk or power off during updating,
 otherwise the operation will fail.

1. Please unzip the file and put the "install.img" file under the root
   directory of a USB flash drive. And insert the flash drive into USB port
   on back of TV.

2. Press "Menu" button on the Remote control first, then press number key “0”
   4 times in a row to enter the hidden Factory Menu before Menu screen disappears.

3. Move cursor to "Software Upgrade" option and press OK key to start upgrading.

4. After about 10 seconds, it will be into the upgrade status, and the screen
   will display the upgrade progress interface.

5. Please keep power on during the upgrading process, it will take about 1~2 min.
   After upgrading successfully, system will auto turn on. 


Good luck,
