Greetings,
I went to the KC9HI CHIRP Recovery site to download the firmware fix for my Baofeng UV-5R+, but can’t find it in the listing. Firmware Message 1 is HN5RV01 and Firmware Message 2 is 1FB297. I am trying to recover from using a file from an older UV-5R.

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