"uv-82 the same chip in a different shell?"

Maybe, probably not. The way these are made even two uv5's can be different, especially the firmware.

When using Chip always download a file from the radio first, even if it's brand new and empty. Don't use that file for any other radio. You can save the information and import that, just not the file.

It has to do with where each version stores information in the radio. Mismatched file and you can brick the radio.
