Maćku,
Wygrzebałem dla Ciebie podane poniżej opisy rozwiązań na grupie TS-2000. Jak rozumiem błąd leży po stronie softu do aktualizacji, a nie radia, i może się pojawić zawsze, gdy podczas wgrywania nowego firmware nastąpi błąd połączenia.
Hello,
A prior posting I made explained the mess I got myself into trying to upgrade
the firmware of my TS-2000 has been happily solved.
The solution was rather simple, to my amazement. Using a terminal program (putty
in serial mode) and a null modem cable connected to another PC, I wanted to see
what the stupid Kenwood firmware update program wanted to know from a working
TS-2000 and wanted to see if it was sending a valid command.
And yes, it is sending a command to the radio, the "TY;" command, which is used
to verify the microprocessor firmware type (Kenwood manual page 140).
Since the firmware update program refuses to continue until it got an answer
from a working TS-2000, I decided to create a fake reply to it on another PC by
going into DOS mode, using the MODE command to setup my COM1 port, and sending a
fake reply of "TY000;" using the echo command to COM1, and voila, IT WORKED. I
tricked the firmware update program to think it got a valid response from a
TS-2000, and the program went to step 2, which was to start the firmware upload
once I set the TS-2000 to receive the firmware update. Well I quickly setup my
broken TS-2000 to receive the firmware update and IT WORKED!!!!
My TS-2000 now has a new firmware, it is working, and my weekend has been saved.

Ok,
Below is an extremely simple solution to do the same spoof as the
program posted in the files section, but done from a DOS prompt using a
Batch or CMD file. All it does is send the response the firmware update
program is expecting.
Just stick the th 4 lines below in a .bat or .cmd file, change the COM
port number in line 1 and 3 and let the program run in a loop. Use a
null modem cable to connect to the computer running the Kenwood firmware
program and that's my solution.
MODE COM1:baud=9600 parity=n data=8 stop=1
:loop
echo TY000; > COM1
GOTO loop
Powodzenia!
