SG300 Firmware Update Failing

[howardh01]

I am trying to update the boot code and firmware on my SG300-20 and SG300-28P.  I deactivated Windows Firewall, Glasswire and Malwarebytes.  I acquired TFTPD64 and extracted it to the C drive in its own folder.  I downloaded the 1.4.1.03 ZIP, extracted it, and TFTp'd the switch with Boot Code version 1.3.5.06.  I then tried to use the firmware that came along with it (ver. 1.4.1.3) but I keep getting a message that says  "Copy: Illegal software format."  Would someone please help me to understand what I am doing wrong?

Perhaps try a different (but newer) firmware version first.

I found the answer 5 minutes after I posted in this forum.  Here is the answer (click here).  Simply upgrade to an intermediary Firmware and upgrade to the latest Boot Code before upgrading to the latest Firmware. 

I've tested it and it works.
