I made a simi-brick out of 2 Baofengs. It look a while, but I was successful in restoring both of these to full use.
I find that lack of understanding how to use Chirp leads to problems in using it.
(Also, and contrary to most rumors, I have never found a programming cable that did not work.)

P.S, Before anyone says anything, the way I program Baofengs, they will not transmit outside of the amateur radio bands.
