Well well, I've got a KG-805G that's not receiving or transmitting anymore after a CHIRP slip-up. I've been playing around with CHIRP-next which is a huge improvement over the UI in my opinion. I tried to write a config to the radio with CHIRP-next and it didn't want to see the radio, so I downgraded to CHIRP-daily and tried to write the config that I had saved from CHIRP-next. After writing the config to the radio the radio started to behave strangely and revert to Chinese language and beep being on after every power cycle, and TX/RX weren't working anymore. So a word of caution with CHIRP-next.
Now, if someone would be so nice as to send me a KG-805G config for CHIRP from a working radio I would love to try to flash it and see whether it fixes my unit.
I've tried flashing a working config using the trashy Wouxun software and the radio still won't TX/RX.
(There's a chance the TX/RX issue is from the radio getting wet which happened in parallel with the programming issues...)
update: I was sent a firmware which confirms that the radio can still RX/TX, still trying to sort out some details. More over here.. .
Moral of the story seems to be: Don't edit an image in CHIRP-next, save it, and then install it in CHIRP-daily.
