Yesterday, I updated the firmware of my green K6 to losehu131hs, and also applied a patch on one side. However, the radio is unable to turn on; pressing F+0 or long-pressing 0 does not work, and all buttons are unresponsive (PTT also has no response). The only option is to shut down and restart.
I'm not sure if anyone else has experienced this, but I suspect it might be due to my own actions or a problem with the firmware. I would appreciate any guidance from an instructor.
