[chirp_users] Trying to upload to BaoFeng radio

I haven’t used my Chirp app in over a year and I am trying to add a repeater to my BaoFeng BF-F8 channels. I was able to open the .img file and make the addition, but I am unable to either download or upload from or to the radio. My Chirp app says it’s 0.4.0

Do I need to upgrade Chirp? If so where and how? Or do I need to look for something else?

Thanks, Whit
