I have several UV5R's and am starting to wonder how the flashing algorithm works. This is due to odd behaviors that I "think" I am seeing.
When flashing, is the total memory replaced included in-factory configuration elements?
That depends. If the firmware version of the image being uploaded and the radio that it is being uploaded to are both known and both exactly match, then the full image is uploaded to the radio.
If the firmware version of either is unknown or the firmware versions don't match, then only a partial upload occurs.
The reason I ask is that I bought a new unit which was serving for data aok, then after flashing an image (including channels) from another device, it seemed to degrade performance.
Degraded in what way?
The purpose of my question is to clarify whether I need to flash units only with their native image updated with data since factory parameters may be impacted by using another image as a baseline.
That is where I would start. I always make and save a "factory" image of all of my CHIRP supported radios as soon as I attach the battery for the first time a before pressing any buttons and turning any knobs.
