Don't worry, it'll get fixed:
I ran into the very same problem. Turned out the culprit was my Dell
notebook computers were the cause. The serial ports were not robust
enough, compared to a PC.
Turn on the radio as such:
(A or B)
A: HOLD the power button for a couple seconds. Let it sit for about a
minute
B: Hold HI/LO down while TAPping power. Let it sit for about a minute.
(I found B worked more often than A. The key is to wait a bit.)
Then restart the Utility
Test the serial connection.
Upon success, re-attempt to load the firmware.
Even if it fails again with resync errors, keep re-trying.
After about 5-6 times it may work.
If that fails, load the MCU/DSP with a desktop computer and avoid using a
notebook computer that reveals the condition.
If you have a spare PC handy and want to get back into the contest, try
loading the firmware with the desktop PC first.
I've been where you are; it's unsettling. But it'll work once you get a
good serial port to load with.
Other things you probably already checked... snugness of connection,
versions of firmware, working straight DB-9 cable. If you make your own,
as the manual says, you only need pins 2,3 and 5 -- which you can make
with spare CAT5 network cable.
Tips from Elecraft that were explained to me recently:
If the load fails, only try to reload the same MCU that failed .. Until it
loads keep the same version in your attempts.
Use a Desktop PC if you can. If your notebook computer works for you
great, but try a desktop if that gives you the resynch errors.
