[chirp_devel] FT-50R

I intend to give a little attention to the FT-50 interface, but before I do, I'd like to know:   What are the chances I will brick the radio?  Are there irreparable mistakes I can make?   For instance, for reasons that I am not clear on, it seems that every (Yaesu) radio programming tool requires that a cloned image be made of the radio, then updated, then sent back to the radio.  If I mess up this image and send it back to the radio, can I render the radio useless?   Thanks, Phil AG4AT
