[Elecraft] K3 FPF firmware load failed

[Pierfrancesco Caci]

Hello,
I tried upgrading the firmware to 4.93 today. I first tried a plain
"send all firmware", MCU load went fine and then FPF failed. I restarted
the K3 as suggested and at this point FPF was listed as 1.16 and no
longer proposed for update. I was able to load DSP firmware after this,
by doing a "send all new firmware". 
Then I turned on advanced mode and tried a couple of times to load FPF
again. This is what I get:


09:33:33 Elecraft K3 Utility for Linux Revision 1.13.8.27
09:33:34 K3 MCU revision 04.93. RS-232 speed 38400 bps.
09:33:48 K3 MCU revision 04.93. RS-232 speed 38400 bps.
09:33:51 Erasing Flash Memory
09:33:55 Sending firmware file "hfpf0116.hex" to FPF
09:36:05 Send FPF firmware failed at load addresst 176128
09:53:46 FPF firmware load failed
09:53:47 K3 MCU revision 04.93. RS-232 speed 38400 bps.
09:53:47 Ready

A small window suggests to check for firmware correctness, but I don't
know where to find this info. Here's the md5 of the file I have:

e6b579198d681e380a60a4036063a2cc  hfpf0116.hex

The radio appears to be working normally (for what I can check not
having an antenna other than the 2m one at this time). 
All front panel buttons and controls seem to do what they're supposed
to. 

What else should I try? 

Pf
