New Fujinet 1.6 won't flash update (Unexpected error: Error connecting to ESP: Failed to connect to ESP32: Invalid head of packet (0xF0)

[ACML]

I have three Fujinet 1.6 units.  One I've had for about six months and two new ones, just showed up yesterday.  I saw that there was a new firmware drop today and I attempted to update all three.  Two worked fine, one of the new ones keeps giving me this error (see below).

Any idea if this is something I can fix on my end.  The other two updated fine, same cable, same machine???

Try holding down FujiNet button A during the entire flashing process

That worked great!  Thank you.  I have to ask, why didn't the other two need the same procedure (holding down button A)?

Could be the USB cable, USB port, the auto reset circuit or some combination of those. Hard to know for sure

Didn't work for my Fujinet 1.6 device. (Before I updated my Fujinet 1.0 without any problems)

Any other workaround?

I added some steps to the wiki that may help if you are using windows.
