TK880 Firmware Update

[WSGI699]

Trying to flash the firmware of an old TK880H Version-1.  First issue is that I can’t find a HEX file for the version-1 to update with.

Second issue is that I don’t know what baud rate to flash at since depressing the scan key when powering on the radio does not provide a rate to use for the update, obviously an important technical setting.  Anyone have any help for this?  Thanks in advance for your response.

Try different bauds until you can read from the radio.

Thanks Steve.  Found the baud rate by looking at the PC COM port used to down load from the radio, but still haven’t found the HEX files for the firmware flash.  Probably all for naught as I can’t get the thing into PROGRAM MODE. Unless I find a way, it’s a door stop.

Will it not work using the current revision of firmware?  Why do you want to upgrade the firmware?
