Hi Dennis,<br>
<br>
These files are not firmware fixed. The firmware in these radios<br>
cannot be changed or updated.<br>
<br>
Most of the CHIRP images that are available there are factory images<br>
that the radio owners downloaded while there radios was still in its<br>
factory delivered state and donated. They are listed by firmware<br>
version that was in the radio they were downloaded form because the<br>
memory layouts can vary and it is not a good idea to swap memory<br>
images between radios having different firmware versions. The firmware<br>
version was a good way to have CHIRP identify which radio model was<br>
being programmed and adjust itself to "match" the radio.<br>
<br>
Unfortunately the HN5RV01 firmware has been showing up in many various<br>
models. In addition to that, not of the images that I have seen that<br>
were downloaded from radios having HN5RV01 always seem to have some<br>
sort of visible corruption. So I decided not to share any of them<br>
publicly. Those that I have shared on a one-to-one basis have not been<br>
successful in "fixing" the issue that the radio owner was having.<br>
<br>
The driver for these radios has changed over the years. It has<br>
eventually been learned which areas of memory can be affected by<br>
uploading a "foreign" image and these areas of memory are now<br>
intentionally skipped during the upload process. It is no longer<br>
possible change these areas of memory so it is not possible to break<br>
or fix these areas of memory either.<br>
