I wonder if there is a key sequence for a full reset. Like hold down some specific buttons while powering it on. Glenn
The UV-82HP has something like three different memory layouts. They are not compatible. So uploading a CHIRP Radio Images (*.img) file from a different radio using an older version of CHIRP that didn't protect for this could cause unwanted side effects. Some have been known to be; 1 the radio won't scan, 2 the radio won't receive unless the [MONI] button is pressed, 3 the radio won't TX.
If this is the case, which I am waiting for a reply to find out, then there is a special method that can perform a full upload of a "compatible" image to correct the problem that was created by previously uploading an "incompatible" image.
CHIRP now tries to protect from this but there is nothing preventing Baofeng from changing the memory layout in another place in the future. This is why I no longer recommend swapping images between Baofeng radios (even if the model and firmware versions are the same). The only safe way is to download from both radios to open a tab for each radios. Copy-and-paste the channels between tabs as needed and finally upload each tab back to the radio that created it.
