That site is indeed correct.  The actual firmware cannot be updated in 
the UV-5R radio.

What your second link contains are a set of image files.  The image 
files contain the contents of the memories and settings for the radio 
(which are not the same as the firmware).

Since the image file is based on the internal storage format of the 
radio, which is dependent upon the firmware level, images are NOT 
compatible across firmware levels.

In the past, some people have ended up loading old images into newer 
radios (and vice versa) which can end up making the radio 
non-functional.  These images exist to allow people to pull in a known 
good image for their firmware level in order to recover the radio if 
they loaded an incorrect image.
