[K3] Firmware update failed - need help

[k.igor]

Tried to update the K3 firmware to 4.67. First, I updated the K3 Utility to the latest version 1.13.5.9. The moment I hit Send All New Firm ware to K3, the K3 went to unresponsive state with MCU LD on the LCD and the TX LED flashing.

This happened before. That time I was able to snap it from this state by holding POWER button while powering the rig. This time, however, this did not help. The K3 Utility cannot connect to to the rig and just keep trying with different bod rates  unsuccessfully.
I do have P3 as well. I know the drill, I disconnected P3 and connected K3 directly, but it did not help as well. I am sure somebody run into this problem before. Please, help!

My K3 S/N is 4653

Last time when this happened, I was using dedicated RS232 port, this time I use USB/Serial adapter with FTDI chip and different computer. I don't know if this can be a problem.



Thanks,



Igor, N1YX
