I have a Quansheng UV-K5(8). I have been using IJV 2.9R5 for many months without major problems.
Last tuesday I upgraded to IJV 3.21. I flashed firmware.N3.21.bin to my radio and then I reset VFO in the service menu. I did not touch the calibration of the radio.
I upgraded my Chirp to latest version (next-20240706) and transferred my channels by cut-and-paste from my 2.9R5 .img file to a new 3.21 file. I uploaded the new .img file to my radio and everything was fine. I changed channels and configuration several times and uploaded it to my radio from Chirp without problems.
Then suddenly after I uploaded data from Chirp to my radio the radio became dead! When I turned the radio on, nothing happened: the LCD was black and the radio was silent. I tried to switch to FM BC (F+FM), change channels, but the radio was dead. S1 + power on did not work either.
The last change to the Chirp file was to create new Groups and assign channels to those groups. I did not assign all channels to groups, is that a problem? And when I create new Groups, Chirp does not show them in the Group pull down menu when updating channels until I restart Chirp.
I tried to read calibration or config from the radio by using K5prog_IJV_V3.exe, but got error "radio not detected" after "sending k5_hello ..". But when I turned the radio off and on, K5prog_IJV_V3.exe displayed:
[00]2.00.06[00]4
[00][00]
UV-K5 Firmware IJV V-3.21
But firmware update mode (PTT+power on) worked! I flashed my previous firmware 2.9R5 to the radio and uploaded my old Chirp .img file to it - and now the radio seems to work fine!
