Firmware Updates

What is firmware?

Firmware is permanent software programmed into a read-only memory (ROM).  If this means nothing to you, it's okay.  Basically, all of the functions for your TV, DVD player, Blu-ray player, XBOX, etc. are controlled by the firmware.  It's a combination of software (program/application) and hardware (the circuitboards and other internals).  On one of the chips, there is a place to store data called read-only-memory, and a software version is stored there to tell your device what to do.  Often times, as with any program, the factory firmware isn't perfect.  Later down the road, manufacturers get complaints about the performance of a device and decide to edit the software for the device.  

When do I need a firmware upgrade?

Symptoms that result from firmware malfunction are normally control issues.  For example, sometimes a blu-ray player will refuse to play newer discs that have just been released.  Sometimes there is a difference in the encoding and the player's firmware won't recognize it, and throw up a "disc read error."  Any menus that work incorrectly may be due to a firmware malfunction as well.  Online services like Netflix are finding their way into TV's and disc players as well.  These services require a lot of extra programming and sometimes don't function quite how they're supposed to.  This is another case where you may need to update the firmware.

Even with all this speculation about certain symptoms, the best way to find out is to go to the manufacturer website and look up the model number.  Often times, the firmware update will be available with the fixes listed.  If your TV or other device has symptoms that are not listed under the firmware update, you don't need one! There's no use putting a cast on your leg when you have pneumonia.

If you have doubts, contact a service center or the manufacturer.

How do I update my firmware?

When updating firmware, you're just replacing the file on the chip in the device that tells everything what to do.  Sometimes features are added, but most of the time, an update just improves the performance of what's already there.

Many companies make the latest firmware available to the public.  All you have to have is a computer with an internet connection and a flash drive.  In some cases, the device is connected to the internet already, so all you have to do is find "software update" in the menus!

The basic procedure is the same for every device, but it does vary between brands and models.  Use this list as anoutline only.  For exact instructions, go to the specific manufacturer's website.  Instructions will be listed with the firmware update online.

Basic Procedure:
  1. Do a google search for "model no. firmware". 
  2. Click on the link that directs you to a URL that looks like it is the manufacturer's website.
  3. Download the firmware file and put it on a USB flashdrive.  A 128MB capacity will do.  Note: Remove all other firmware files from the USB flashdrive beforehand!
  4. Generally, you just plug it into a USB port on the device and a menu will automatically pop up.  It will show your current firmware version as well as the version that is on the flashdrive, offering two options: "UPDATE" and "CANCEL."
  5. Use the remote to select "UPDATE" and let it go!  Often times, the device will simply power off when done.
  6. Power the device up again and if everything works, you did it!
Ending Notes

Keep in mind that anything you choose to do is at your own expense.  If at any time power is lost to the device during a firmware update, you may end up with the equivalent to a taxi cab driver that doesn't know the streets he's driving on.  The device will simply not work without a "pilot."  So, don't let your dogs or toddlers near the power cord and don't do this at a time where power may be lost!

I want to say again that you need to follow manufacturer instructions and that this is only a general guide.  If you have any questions, feel free to comment!
