[chirp_users] Changing data Baofeng UV5

I gave up trying to programme my Baofeng UV-5RV2+ using the previous CHIRP release.

When CHIRP next came out, I thought maybe I could get it to programme my radio.

I went through the steps to grab an *img file and load it into the radio.

Then I saved it with modifications then downloaded, with a window saying "cloning".

Exiting CHIRP, turning the radio off and on does NOT change the file.

Am I doing something wrong?
